TMJ Health
At the completion of comprehensive treatment we want the condyle (the ball of the
ball and socket of the jaw joint) centered in the middle of the fibro-cartilaginous
disc, seated completely in the fossa (jaw joint socket). As the patient arcs to
full closure we want the teeth to meet in a functionally correct manner. If we have
this harmony between the best jaw joint position and the best dental fit, the teeth
will help support the jaw joints (temporomandibular joint) and the joints will help
support the dentition. This proper relationship also helps maintain stability of
the teeth and reduces dental relapse (shifting of teeth). This also gives the patient
the best mechanical relationship of the jaw joint to allow for normal wear and tear
on this joint and not accelerated wear. Hopefully, this will help reduce the risk
of dysfunction (TMD, or temporomandibular dysfunction).
Periodontal Health
The second treatment objective is to complete treatment with all of the roots well
encompassed in the alveolar bone (the bone that holds the teeth) with adequate and
healthy gingiva (soft tissue-gums). This may sound very obvious but if one isnt
careful in the treatment planning stage the roots can be placed in a precarious
position. The roots can be placed too close to the edge of the alveolar bone, which
can result in weakened bone and soft tissue (gum) support. If you have ever seen
an eye tooth (canine) which has been crowded out of the dental arch, the tissue
around this tooth is thin and quit often has receded. This loss of support has occurred
naturally but obviously is not good. This same loss of support for the teeth can
occur when too large of dental compensations have been made for the existing underlying
problems such as narrow dental arches or large skeletal discrepancies treated with
braces only. Many times the problems created will not become apparent until the
patient is in his or her mid twenties or later.
Proper Functional Occlusion
Did you know that every groove on the surface of every tooth has a specific purpose
as relates to how your jaw and teeth function in harmony? We have very specific
and technical treatment goals concerning function. This encompasses not only the
teeth but also the jaw joints and the supporting structures. We mount every patients
models on a mechanical device called an articulator. This device is adjusted from
careful measurements of each patient to reflect the relationship of the upper jaw
to the jaw joints and mimics the movement of the jaw in the best jaw joint position.
Another device records the jaw joint position within tenths of millimeters. The
treatment plan needs to be made from the best jaw joint position and not how the
teeth are habitually put together. If our goal is to complete treatment with the
best jaw joint position coinciding with the best functional occlusion (bite), this
diagnostic procedure is critical to success. Without a map, how does one know where
one is going?
Maintaining or Enhancing Facial Features
The wonderful thing about human beings is that we are all unique. What a boring
place it would be if we were all exactly the same in every way! It is our goal to
enhance (when necessary and if possible) ones facial harmony. For example, in some
instances, teeth displaced due to habits such as thumb sucking can have a negative
effect on ones facial harmony. This, in most cases, is easily corrected and can
make a huge improvement in the harmony of ones facial features as well as improve
the function. In other instances the upper and lower jaws may not be in proper relationship
to each other making facial features less than desirable. This too can be corrected
to insure the best function and facial features. In many if not most of the situations
presented to us we want to complete treatment and maintain the favorable facial
features that already exist. In other words we want to choose the best treatment
approach that fulfills all of our treatment goals and have the patient look like
the same individual when we complete the treatment! This sounds simple but the proper
treatment approach is critical to the outcome when we are presented with significant
dental discrepancies and yet the patient has good facial harmony.
Dental Esthetics
Every one of us has an innate idea of what makes a pretty or handsome smile. The
good news is that form follows function. This means that if we get the teeth in
the proper functional relationships we are 90% of the way there. However one size
does not fit all. Ones facial form (square, square tapering, tapering, etc.), the
width of the soft tissue smile, lip posture and other factors can significantly
affect the esthetics of the smile. Other factors such as tooth discoloration, misshapen
and chipped teeth and the level of the gum line can also affect the esthetics of
the smile. These factors will be discussed with you and your family dentist and
the appropriate referrals will be made to address these problems. Nothing serves
one better throughout life than a wonderful smile!
Stability
When the comprehensive treatment is completed we would hope for the best long-term
stability. It is our goal that treatment will never need to be repeated. Many factors
play a role here. If the treatment goals above are achieved, this goes a long way
in insuring good long-term stability. Habits such as tongue thrust, mouth breathing
and making large dental compensations for significant skeletal discrepancies all
have an adverse affect on long term stability. We want what you want, which are
the best results possible given the specific situation of each patient. This requires
the best diagnosis, treatment planning and patient cooperation possible. This is
why we feel your initial examination appointment is the very most important. We
can agree on a mutually acceptable treatment plan with clear objectives. If there
will be limitations of treatment we can discuss these at the outset.
