The following dental information pages answers many of
your questions on partial dentures.
What are removable partial dentures?
When only a few teeth are missing, a partial denture is advised for the
patient. The first choice of course would be a fixed partial denture (FPD).
Unfortunately an FPD can replace only limited number of teeth. Replacing
too many lost teeth with an FPD would place tremendous strain on the remaining
teeth. So in these cases, a removable partial denture (RPD) would be the
ideal choice. The removable partial denture can be placed and removed by
the patient and can be made to replace many missing teeth.
What are cast partial dentures?
A removable partial denture can be made of acrylic (plastic like material)
or a combination of acrylic with metallic framework. The metallic framework
is usually made of cast metal. The metal used may be gold based or chrome
cobalt alloy. These metallic dentures or cast partial dentures are much
superior to the regular acrylic dentures.
What are Valplast Partials
Valplat is a type of flexible denture material that can be used to fabricate
partial dentures. These materials unlike traditional plastic dentures are
flexible and therefore makes the denture flexible. The advantages these
dentures have over the hard plastic dentures inckude flexibility, lighter
in weight and can be fabricated smaller in size.
How do the partial dentures stay in place?
Partial dentures use a variety of mechanisms to stay in place. Close physical
contact of the denture with the underlying soft tissue along with the intervening
saliva provides one means of retention. In addition the cast partial dentures
have metallic clasps, which hold on to the remaining teeth that help in
keeping the denture in place.
