Everyone talks about extreme makeover these days.
It involves the entire face, which evidently includes
the jaws and the teeth. Extreme makeover is a term that
was created to underline the dramatic changes that can
be created with plastic surgery and cosmetic
dentistry. An extreme makeover should be a holistic
approach that considers the functional aspects of all
involved structures.

Anatomy of a smile: the pull of a variety of small, but very responsive facial muscles.
While all changes to the face have a functional impact, even a minor change
within the stomatognathic (chewing) system needs to be based entirely on function.
Aesthetics cannot be achieved without function. In fact, any aesthetically pleasing object,
except those created in the field of art, evolved within a framework of function and interaction.
Beauty is harmony. So, let us talk about how that applies to your teeth and jaws.
What is a smile? We cannot discuss its philosophical and spiritual significance at this point.
However, it is important for a plastic surgeon or cosmetic dentist to understand the anatomical,
functional, and physiological aspects of a smile.
We have a large group of specialized mimical muscles that contract in certain situations
and pull the overlying soft tissues into a smile (see above image).
Teeth become exposed. The amount of tooth exposed during a smile varies from patient to patient.
A young person displays more tooth surface than an older person. This is caused by two things:
the progressive sagging of the upper lip and the attrition (shortening) of the upper incisors.
These signs of aging are the main reasons why many middle-aged individuals decide to 'lift' their smile
by lengthening their front teeth with porcelain veneers.
They often receive six to ten upper porcelain veneers.
However, any dimensional change of the front teeth has to consider stomatognathic function.
The front teeth are vital for the protection of the molars.
Front teeth are responsible for the disclosure of the back teeth during horizontal movements of the jaws.
Muscles shut off when front teeth are stressed by tooth contact.
This natural mechanism protects all oral structures.
This image explains the concept of 'envelope of function'
(blue line). The envelope of function is a key element of
smile design. Ignoring it will cause your new smile to be
unstabil and porcelain restorations to break.
Smile design therefore cannot just focus on aesthetic
parameters, but must be created within the 'envelope
of function' of the front teeth. When you receive
a new smile, it is not just 'painted' into your face.
It is integrated in complete functional harmony with
the surrounding structures of the skull.
Any master in plastic surgery or cosmetic
dentistry fully understands the reason for morphology
and aging, such as.''Why does the jaw have an angle?''
or,''Why do eyelids become baggy?'' or,''What do we
need to do to rejuvenate a smile?''
Any extreme makeover of the teeth has to be based on the physiological relationship of upper and lower
jaw. There are many heated discussions regarding the finding of the proper jaw relationship
(centric relation) among the dental community. The most predictable results have been obtained by
techniques developed by Dr. Peter Dawson in St. Petersburg, Florida.
Your new smile will be permanent and beautiful if all functional aspects were considered.
This image underlines the fact that teeth cannot be altered without consideration of
the relationship of the jaws, which meet at the temporo-mandibular joints. The dental contacts determine
the position and relationship of the joints upon closure and need to be in harmony with their
physiological position.
The following extreme-makeover smile design is the result of a careful consideration of the
relationship of upper and lower jaw. The patient was set into her natural centric relationship prior
to raising her bite. This allowed us to create the space necessary to rebuild the worn teeth without
changing the most physiological position of the mandibular condyle into the temporal fossa of the skull.
The makeover is truly extreme. However, the final result of this full-mouth reconstruction lead to a much
healthier condition of all oral and masticatory structures involved.
