Process for Making Removable Dentures

How Complete Dentures Are Made
 Your
dentist will take an impression of your jaw, along with measurements
of how your jaws relate to one another and how much space
is between them (your "bite relationship"). The
color (shade) of your teeth will also be determined either
from your natural teeth or from a denture you may already
be wearing. The impression, bite and shade are given to the
dental laboratory so a denture can be made just for you.
The dental laboratory
makes a mold (model) of your jaw, places the teeth in a wax
base, and carves the wax to the exact form desired in the finished
denture. Usually a "wax try-in" of the denture will
be done at the dentist's office so any adjustments can be
done before the denture is completed.
The
denture is completed at the dental laboratory using the "lost
wax" technique. A mold of the wax-up denture is made,
the wax is removed and the remaining space is filled with
pink plastic in dough form. The mold is then heated to harden
the plastic. The denture is then polished and ready for the
patient to wear.
How Partial Dentures Are Made
 Like
complete dentures, your dentist takes an impression of your
jaw, along with measurements of how your jaws relate to one
another and how much space is between them (your "bite
relationship"). The color (shade) of your teeth will
be determined either from your natural teeth or from a partial
denture you may already have. The impression, bite and shade
are given to the dental laboratory so a partial denture can
be made just for you.
If the partial
denture is to be made of metal and acrylic, the dental laboratory
makes a mold (model) and then wax forms or plastic patterns are
placed in the exact shape and position that the metal is to
be in. The "lost wax" technique is used to replace
the wax patterns with metal. Once the metal framework has
been cast, it is then polished and is ready for the teeth
and plastic (acrylic) to be placed.
If the partial
denture is to be all-acrylic with clasps, the dental laboratory
makes a mold (model) and a wax representation of the partial
denture,
including teeth. At times, a "wax try-in" will be
done at the dentist's office so any adjustments may be done
before the partial is completed. The partial is then completed
at the dental laboratory in a manner similar to complete
dentures.
