PARTIAL DENTURES
When numerous
teeth are missing, one possible solution is to have a partial denture
(often referred to as a “partial”) made. The design of the partial is
dependent on the number of teeth missing. Stability of the final work
is very important, if there is movement while chewing, the less comfort
and functional it has. Below is one case study of what could be
considered a routine partial denture.
The first step in a
successful partial denture is to design and plan the case very
carefully. The more time taken with this important step, the more
secure and functional the resulting partial.
Next, the metal framework is
fabricated by first creating it in wax and then, through a series of
intricate steps, casting it into a very strong metal.
- Although there are several metals
available for casting. Titanium is the metal we choose most often
because of its strength and light weight. Only a few dental
laboratories in the country can work with titanium - most offices do
not offer this type of service.
In this step, the denture
teeth have been set into a proper bite utilizing a model of the
opposing teeth as a guide (not shown). Acrylic that matches the color
of healthy gum tissue is used to bind to both the metal framework and
the teeth. The partial is now ready for try-in and delivery to the
patient.
A finished partial. Notice how
the metal shows slightly around the front of the teeth. Although the
metal can be seen in this view - it will not be an appearance problem
when the lips resume their normal position.

There are other types of partials available as well.
for example, it is possible to hide all the metal from view. These
types of partials are referred to as precision (cosmetic) partial
dentures.
