What
Are Dental Implants?
Dental implants are a state-of-the-art method that solves many
problems associated with dentures and partial dentures. They
eliminate the need for a removable partial denture by providing the
support necessary for attachment of a fixed bridge. Implants can
provide a strong attachment to secure dentures to bone. Indeed,
implants offer the ideal solution for the patient who finds
removable partial dentures or complete dentures uncomfortable or
unsatisfactory.
What Can Dental Implants Do For Me?
Provide a method for anchoring your lower or upper denture.
Provide a method for replacing your partial or full denture with
fixed bridgework. Provide a method for replacing a single tooth.
Improve quality of life by removing many frustrations associated
with using dentures or removable bridgework. Improve chewing
function and restore the feeling of natural tooth function.
Are Dental Implants Right For Me?
Consult with Dr. Mendel on your oral rehabilitation program,
including dental implants. He will need a complete health history,
dental x-rays, and oral examination. Impressions of your mouth will
probably be requested as well. After evaluating the results of these
tests, Dr. Mendel will recommend you to an appropriate treatment
plan. Remember, not everyone who is missing teeth is a candidate for
implant restoration. Generally, anyone who is healthy enough to have
routine extractions can be considered for dental implants.
How Do Implants Work?
Dr. Mendel carefully "integrates" small titanium
anchorage units into your jawbone. During the healing process and
afterwards, your bone tissue unites directly to the anchorage
units - a process called osseointegration.
Titanium is a remarkable, space-age metal which has the unique
ability to form a permanent, biological bond with bone.
Once the anchorage units form a bond with your jawbone, Dr.
Mendel attaches either a permanent or removable bridgework onto
the anchors.
The insertion of the implants is a surgical procedure done in a
single office visit. Most patients report only minor discomfort
similar to that associated with a simple tooth extraction.
After a healing procedure of 3 to 6 months, a second procedure
is needed to expose the top of the implant so the fixed bridgework
may be fabricated.
After this procedure, many patients think they have
"real" teeth in their mouth.
How Long Will My Implants Last?
In a 20-year Swedish study of patients without teeth, thousands
of titanium screw implants were inserted for support of fixed
bridges. Findings of this research showed that if implant attachment
to living bone (osseointegration) is attained, there is very little
chance the implant would be lost.
Other studies have shown the implants used by Dr. Mendel achieve
osseointegration on a highly consistent basis.
What Dr. Mendel’s Patients Say About Implants:
"I have had dentures for 35 years and this is
the first time I have been able to eat peanuts."
"I never felt really comfortable around
people because my lower denture might pop-up. Now my confidence is
up 100 percent, and I even think my speech is better. It’s such a
good feeling."
"They’re well worth the investment. I feel
like my teeth are a part of me and I can even sit down and eat a
steak."

Hope For An Old Problem

Case 1
Mr. G. is 66 years old and has been wearing dentures since he was
25. Over the years the bone that supported his dentures has been
gradually deteriorating. For the past ten years it has been
increasingly more difficult to keep the denture in place and the
bottom plate hurts constantly when chewing. Eating has become a
problem. He is limited in what he can chew and is embarrassed to eat
in a restaurant. The inability to properly chew, his food has led to
digestive problems and he feels like he is not properly nourished.
Two implants were placed in the lower jaw and a new set of
dentures adapted for the implants. He has been using the implants
for five years now, gained 30 pounds and proudly informed me he was
eating peanut brittle with his family at Christmas.
Case 2
Tamie is 14 years old and has been missing one of her adult front
teeth since an accident at age eight. She has been wearing a small
removable partial denture to fill in the "hole". She is
constantly aware of this physical abnormality. She does not want to
talk in class, worries that a boy might not like it, and simply can
not eat a sandwich with it. A fixed bridge could be made, but
because of the spacing between her front teeth, this would look
unnatural.
Tamie received a single implant in the missing space and a crown
that matched her other front teeth. The spaces between her front
teeth are now even. She can talk with boys now, eat sandwiches and
not feel "different".
Case 3
Mrs. K lost her upper teeth at age 65 to pyorrhea (gum disease).
She has been trying to wear an upper denture for six months and
hates it. It feels as big as a brick, inhibits her sense of taste,
tends to gag her, and at times will slip when she wants to smile.
She has been so preoccupied by the denture that it has become a
psychological problem affecting her self-esteem.
Six implants were placed and fixed bridges secured to the
implants. She can eat anything she wants, smile confidently and,
most important, she feels like a whole person again.
Case 4
Jim is 40 and has lost several teeth to gum disease. Rather than
prepare multiple teeth for bridges, single implants are placed where
the missing teeth are. Each implant will be used to support a single
crown. The result is an excellent bite and natural appearance,
without a partial denture or even fixed bridges.
Case 5
Mrs. Q has had several different removable partial dentures made
for her lower jaw. All of them are uncomfortable. She has a large
growth of bone called torl on the mandible that makes wearing any
removable appliance difficult.
Three implants were placed toward the back of the mandible with
fixed bridges supported by implants toward the back and natural
teeth in the front. The result is a natural appearance with no metal
showing and all teeth supported by bone and not gum tissue. The
patient is tree from any bars, plates or clasps.
There are as many different individual problems created, by
missing teeth as there are people. There Is now a new branch of
dentistry that can give hope to those people that are missing some
or all of their teeth. This branch of dentistry Is called
Implantology or Implant Dentistry. If involves the placement of
Titanium anchors in the jawbone and securing replacement teeth to
these anchors. There is some special training and skill that a
dentist must develop before placing the implants, but the process of
placing an implant is not difficult or dangerous. Placing the
implant is no more traumatic than extracting a tooth. In fact every
patient I have placed an implant for, goes away from the surgery
with a positive feeling because he is gaining something, not losing
something.
The concept of replacing a missing tooth with an artificial tooth
has been around since ancient times. The Egyptians tried to implant
missing teeth with ivory teeth that were hand-carved to the shape of
the missing tooth and placed into the bone.
Patents were filed in this country around the turn of the century
for Dental Implants to replace the missing roots of teeth. Until
recently, twenty years ago, the technology did not exist to give a
patient an implant with the strength needed for chewing and a useful
service life. With the advent of the titanium implant and new
techniques, these implants are incredibly strong, with a long and
predictable service life.
About 20 years ago a European physician made an amazing discovery
while doing research on dogs. Titanium and bone grew together to
forma tight, rigid union called osseointegration. Dr. Branemark
spent the next few years experimenting and developing Titanium
Implants to support replacement teeth. With more than 20 years of
research and development titanium Implants have become a viable
alternative for missing teeth. Ther are several different brands of
Titanium Implants on the market today. They all seem to achieve
osseointegration and can be used to support replacement teeth.
The placement of the implants is a simple surgical procedure that
is routinely achieved under local anesthetics. The tissue over the
implant site is pushed away to expose the bone. A recipient space is
created in the bone to the exact shape of the implant and the
implant is placed In the bone. The tissue is repositioned and
secured with sutures. There is now a period of three to six months
in which the bone and implant fuse together - osseointegration. The
patient can wear his denture or partial denture while
osseointegration is being achieved. After the implant and bone have
formed a rigged union, the replacement teeth can be attached to the
implants.
There are five basic ways implants can be utilized. Two or three
implants can be placed and used to stabilize a denture to keep it
from shifting and relieve some pressure from the gums. Four or five
implants can be placed to completely support a denture and hold it
locked in place. Six to eight implants can be placed and fixed
bridges made to completely eliminate a denture and return the
patient to what looks and feels like natural teeth. A single implant
can replace a single missing tooth. Implants can be used in
conjunction with natural teeth to form a fixed bridge to replace
partial dentures.
The applications for dental for implants are many and vary
according to each individual. Any individual that is missing all or
some teeth may be a candidate for implants.
Normally an examination and consultation is given to determine
the exact nature of the individual’s problem, his health history,
suitable areas for implants to be placed, and what replacement
modality would best be suited to the individual’s needs and
desires.
This Is an exciting new era in dentistry - a time when patients,
now have an opportunity to replace missing teeth with implants that
can bring back normal function and appearance. My staff and I are
thrilled to be a part of this service.
Social
Insecurity
By David Leslie, DMD

Back to Top
Dental Social Security is an attractive smile, healthy looking
teeth and the ability to eat a meal in public without feeling
embarrassment.
For many people these things do not exist. The loss of teeth and
the bone that supports a partial denture or complete denture results
in dysfunction, sinking in of the facial contours and dentures that
will not stay in place. This in time produces the inability to
properly chew food.
For Mrs. G, social insecurity meant an upper denture that might
slip when she smiled or tried to eat. The upper denture was an
embarrassment and made her uncomfortable around her friends, because
it might drop at any time. She wanted to be able to laugh and eat
with her friends and not worry.
Mr. R. was the president of a small firm and needed to present a
strong image to the public, his lower denture would not stay in
place. Eating in public was a nightmare, he could not chew well and
his diet was limited. Speaking was even more of a problem because
the lower denture was pushed around with the movement of the tongue
as he spoke. He had learned how to hold the denture in place with
his tongue, but sometimes it required some conscious thought to keep
the denture in place when talking.
The answer to these problems has been the titanium dental
implant. There are thousands of individual stories of people that
wear partial dentures or complete dentures that now with titanium
dental implants once again have a functional set of teeth that are
secure and attractive.
Mrs. G. received six titanium implants and a fixed bridge on the
upper jaw. With the new bridge she has absolute confidence that her
teeth will stay in place and she can laugh and smile without fear of
her teeth ever coming out.
Mr. R. has four implants and a lower denture that is fastened to
them by two small locking devices. The denture cannot be removed
unless he releases both locks. He has excellent chewing ability now
and can cat corn on the cob, apples, and steaks to his heart’s
content. Speaking is no longer a problem because his teeth are
stable and even his diction has Improved.
These two examples are typical of the many different situations
that arise for people that have lost all or some of their teeth. For
many people traditional partial dentures and complete dentures are
not the answer to their needs. If sufficient existing bone is
present the titanium implant can be the answer many people have
waited so long for.
The steps involved in Implant dentistry are examination,
treatment planning, placement of the implants, osseointegration,
uncovering the implants, and building the bridgework on the
implants. The examination consists or an oral examination of present
conditions, x-rays, and a review of the health history. Based on
these findings a recommendation is made as to what would be best for
the patient in terms of remaining bone, number and types of
implants, and the type of bridge that would work with the implants
placed.
The actual placement of the implants is a minor surgical
procedure that is normally accomplished in a physician’s office
using local anesthesia. The tissue over the implant site is pushed
away to expose the underlying bone. A recipient space is created in
the bone to the exact shape of the implant and the implant is placed
in the bone The tissue is repositioned and secured with sutures.
There is now a period of three to six months in which the bone and
implant fuse together. This fusing of bone and implant is termed
osseointegration. When an implant has reached osseointegration there
is an incredibly strong bond formed between the implant and the
bone. During the three to six month period for osseointegration, the
patient can wear his or her denture or partial denture.
After the osseointegration phase, building the bridge work may
commence. The most common case in our practice is placing four or
five implants to completely support a lower denture and hold it in
place with two locking devices. There is no pressure on the tissue
and the denture is completely supported by the bone around the
implants. Six to eight implants can be placed in either the upper or
lower jaw and fixed bridges made to completely eliminate the need
for a removable denture. This bridge returns the patient to what
looks and feels like natural teeth. A single Implant can be used to
replace a single missing tooth to avoid making a bridge. For many
people partial dentures are uncomfortable and bulky. Utilizing
implants and natural teeth to support fixed bridges seems to work
exceptionally well in eliminating the partial denture and restoring
normal chewing function.
There are many different individual problems caused by missing
teeth and each person reflects these individual differences. Now the
titanium dental implant can give hope to those people that are
missing all or some teeth to restore normal function and appearance.
The branch of dentistry that deals with implants is called
implantology or simply implant dentistry. It involves the placement
of titanium anchors in the jawbone and securing replacement teeth to
these anchors. There is some advanced training and skill that a
dentist must develop before placing implants, but the process of
placing an implant is not difficult or dangerous. It is usually less
traumatic than extracting a tooth. Patients leave the implant
surgery feeling very positive. They are gaining something, not
losing something.
There has been some controversy over the best type of implant.
These are the result of the many manufacturers of the implants in
competition with each other. All the implants are basically the
same. They are small cylinders of pure titanium or a medical grade
of titanium alloy. They all seem to osseointegrate with the bone and
form a strong base for the replacement teeth. The competition among
manufacturers has had a positive effect in producing a very good
product, but added some confusion to the public. In selecting an
implant system it is more important to know the experience and
training of the dentist than the actual brand of implant being used.
It Is like flying; if you have confidence in your pilot, you will
have confidence in the flight.
Since conception of implants the techniques and materials have
constantly improved to give the patient a better result. There are
now studies of ten, fifteen, and twenty years that demonstrate a
very high success rate of more than a 90% retention rate. Dental
implants enjoy a very high degree of success for a medical procedure
with few complications or side effects.
The concept of replacing a missing tooth with an artificial tooth
has intrigued the medical field since ancient times. The early
Egyptians implanted carved Ivory teeth to replace missing teeth. The
Mayas of Central America missing teeth with shaved bits of seashell
driven into the bone. In this country, patents were filed around the
turn of the century for dental implants to replace the missing roots
of teeth. Until recently, almost twenty five years ago, the
technology did not exist to give a patient an implant with the
strength needed for chewing and a useful service life. The advent of
the titanium implants and new placement techniques showed
predictable results can be achieved. The strength of the bond
of bone and implant is suitable for the high pressures of normal
chewing and the service life of the implants is extremely long.
Almost twenty rive years ago a European physician, Dr. Branemark,
began experimenting with titanium implants and bone growth. He soon
realized that titanium was an excellent material to replace missing
roots of teeth. The way titanium and bone grow together (osseointegration)
allows for a strong bone-implant union. This discovery produced the
first titanium dental implants. Over the last two decades
techniques, designs, and materials have been developed to improve
the placement and predictabilily of the titanium implant.
This is a truly amazing era we live in today. Science and
technology have combined in the field of Dentistry to give a
remarkable new opportunity to people that have lost teeth to regain
normal function and appearance. No longer do people have to suffer
with the social insecurity of loose fitting, bulky dentures and
partial dentures. The answer for you or someone you know is the
titanium dental implant and the first step is to contact one of the
many dentists now placing implants to find out if you are a
candidate for this procedure. We are excited about working in this
rapidly expanding branch of dentistry, and take pride in presenting
implants for our patients.
Dentures
To Be Or Not To Be

Dental Implants May Allow You To Chew Properly & Smile
Without Embarrassment.
For more than 40 million Americans, dentures are a way of We.
Most denture wearers have adjusted well to these prosthetic devices.
They are able to chew reasonably well, and the appearance is good.
There are a large number of people, however, with full or partial
dentures that have continual problems.
Typical complaints by denture wearers include: food getting under
a denture and pinching in the gum while chewing; dentures that slip
out of place at the most inconvenient times; lower dentures that
exert too much pressure on the gum to tolerate; upper dentures that
block the palate, cutting off the sense of taste and the feel of
food as well as dulling the sense of hot and cold; dentures and
partial dentures that feel bulky and unnatural.
Dentures and partial dentures are not natural. They are plastic
prosthetic devices that are an inexpensive means of replacing
missing teeth.
Dentures have limitations. The most serious limitation is the
continuous loss of bone in the jaws once the teeth have been
extracted. The sunken-in appearance of the faces of many long-term
denture wearers (15-30 years) is the result of this continuous bone
loss. Many long-term denture wearers are very disappointed when,
after 20 years of wearing, their dentures will not stay in place and
new dentures do not solve the problem. This is simply caused by the
gradual loss of the supporting bone for the denture. These people
become increasingly uncomfortable with dentures as the years pass.
A denture or partial denture needs to he changed or re-lined
every five to seven years in order to properly conform to the
gradual changes of the supporting bone.
There are, of course, those denture wearers that would rather
have a denture than their natural teeth because their natural teeth
brought about so much pain and discomfort to them. However the vast
majority of denture wearers would love to have natural feeling,
looking and functioning teeth. This is what implant dentistry can
offer these individuals - a second chance to have teeth that look,
feel and function naturally.
What are the benefits of implants versus dentures or partial
dentures? The first and foremost is a dramatic return of the
function of chewing. An implant is a titanium anchor. It is fused to
bone and allows the individual to chew with bone support rather than
having a plastic device dig into the gum when chewing. The increase
in chewing ability is obvious.
It is truly amazing to see people that have suffered for many
years with the limitations of chewing come to me one day to get
implants - not because they cannot chew properly - but because of
some embarrassing situation. One woman lost her denture when she
laughed in front of her girlfriends on the golf course. A
businessman lost his plate at an important business meeting when he
coughed. Another woman was embarrassed when her grandchildren
laughed at her as she took her teeth out.
All these incidents triggered a desire to correct a problem of
confidence and self-worth. Perhaps more than anything else, the
return of an individual’s feelings of wholeness and renewed
self-esteem are the most important benefits implants can offer.
Another noteworthy attribute of implants is that unlike dentures,
which need routine work every few years, all indications are that
implants will last virtually a lifetime.
Along with the many benefits, individuals should be well informed
of the drawbacks of which may be associated with implants.
First of all, there are surgical procedures involved in the
placement. This seems to be a sticking point with many candidates
worried about going through a surgery. But almost everyone is
pleasantly surprised at how little discomfort is really involved
during and after the procedure.
Implants do, however, take time. It takes a minimum of four
months to place the implants, let them integrate with the bone and
then build the final replacement teeth.
Implants do no work all the time. They are successful about 95%
of the time, but about 1 in 20 will not form a union with the bone.
In this uncommon incidence, additional implants can be placed or
alternate plans can be made.
Cost is the other factor that limits treatment with implants.
Stabilizing a lower denture with two implants runs about $3,700.
Utilizing four implants to support a lower denture would be about
%5,800. Placing six implants and replacing a denture with a fixed
bridge (teeth that are not removed from the implants) could cost
about $9,000.
Because each person has unique conditions, needs and
expectations, the first step in the implant process always involves
an evaluation of one’s particular case. An oral examination I
performed with X-rays and a review of the patient’s health
history.
Following an extensive review of the initial evaluation, a
treatment plan is presented which clearly details what can be done
utilizing implants in order to solve the individual’s problems.
Fees are then discussed, along with the benefits and limitations.
Once the treatment is agreed upon, the implants can be placed. The
placement of titanium implants is a minor surgical procedure
routinely performed a dentist’s office utilizing local
anesthetics. Normally a patient can wear existing dentures or
partial dentures for all or most of the time the implant(s) and bone
are bonding together. This bonding of titanium and bone is called
osseointegration. The time required for this bonding process varies
from three to four months and in some cases can take as long as six
months, depending on the bone and type of implant.
After the implant is anchored to the bone, it is uncovered and
tested for stability. If it is secure, the rebuilding of the
replacement teeth begins. The replacement teeth can vary from single
tooth to an entire mouth of teeth, depending on how many implants
were placed.
The total time involved from placement of the implants to
delivery of the replacement teeth is between 4 and 7 1/2 months with
variances determined by the complexity of the case. It is always
interesting to see a patient’s building enthusiasm as the long
awaited day approaches and then to witness the gratification the
feel with their new teeth. It is usually reflected in the big smile
that they want everyone to see.
The use of dental implants has grown tremendously in the past 15
years. Ove that time, new techniques to place implants stimulate
bone regeneration have been developed and more are on the horizon.
Before long, we expect to see new materials developed that will
stimulate the growth of new bone to replace last bone. We will also
see new techniques and materials that will shorten the bonding time
of implants to the bone.
Many dentists have training with implants. Some have been trained
only to place or build on the implants. Others are experienced in
both placing and building on dental implants. Dental schools are
teaching basic implant techniques. Through articles like this we
hope to increase public awareness about dental implants – and to
offer renewed hope for those denture wearers who may have long ago
forgotten the feeling of comfortable, fully functioning teeth.
The
Facts About Dentures
By David Leslie, DMD
Reprinted with permission
Back to Top
Joe: "I’ve had this same set of plates since
1980. They feel great and I can eat anything I want; corn on the
cob, steak ... no problem!"
Bill: "I got these plates two years ago and
they are a constant bother. The bottom one won’t stay in place,
there are sore spots and I can not eat what I really want. All I eat
are soft foods like mashed potatoes and soups."
These are two extremes in the world of the denture wearer. Each
of these individuals is speaking the truth as he has experienced it.
For most people the truth lies somewhere in between these two
extremes. We are all physically unique individuals. What works for
one person won’t necessarily be correct for another. Dentures are
custom made to each individual’s mouth. Success or failure depends
on the bone and tissue support of the individual and the skill and
experience of the dentist.
If you have ever considered the possibility that you may someday
need to go to al denture there some facts you should be made aware
of.
- There is a gradual, continuous loss of bone support under the
denture. Just because the denture fits well at age 40 does not
mean that there will be enough bone at age 65 to support a
denture in comfort and still function well.
- The lower denture does not normally form a suction. The only
thing that holds it in place is the tongue. Any movement of the
tongue tends to dislodge the lower denture.
- The denture is a solid chewing surface. It may act like a
teeter-totter. That is, if you put pressure on one side, the
other side tends to ride up and come loose.
- The upper denture covers the palate. It inhibits, sensations
of taste, temperature (hot and cold), and the texture of food.
- Chewing ability is affected by the amount of pressure that the
denture can place on the gums without causing pain. In other
words, you can chew as hard as you can tolerate the denture
pinching the gums. This is about 1/6 the normal chewing force
available to a person with natural teeth.
- Dentures are a prosthetic device. They are artificial
substitutes for natural teeth. If you had an artificial leg you
would not expect to run a mile in four minutes. A similar
comparison is true for dentures - they are not as efficient as a
normally functioning set of natural teeth.
First and foremost, invest in your health, take time, energy and
money it necessary to keep your natural teeth.
There are excellent dental services available. See to it that you
and your children get the proper preventative care to maintain your
teeth for a lifetime.
If you have existing dentures that do not seem to be functioning
properly consider replacing them. You may have unique problems that
require special construction of dentures. There are soft linings
that can be fitted to dentures to help with sore spots. Available to
us today are dental implants,. These implants can stabilize dentures
or completely replace the dentures with teeth firmly anchored to the
jawbone.
