Denture

There are two major types of dentures. The Full Denture replaces an entire jaw’s dentition, while a Partial Denture only replaces multiple or single teeth where there are still healthy teeth present.
A partial denture also serves as a spacer to prevent the living teeth from shifting position.

   

COMPLETE DENTURES: This is the most economic and most traditional method of tooth replacement. Dentures are removable objects that simulate the look and function of the tooth and its surrounding tissue. Most dentures are constructed with acrylic resins along with some composite materials. However patient can chose from a variety of options:

  • Traditional plastic denture
  • Traditional plastic denture with a metal framework to make the denture strong,
    light and of course biocompatible.
  • Flexible denture(valplast)
  • Flexible denture(valplast) combined with metal framework

THE PLASTIC REMOVABLE PARTIAL DENTURE
This is the least expensive of all the removable partial dentures. These dentures are generally used for temporary or intermediary purpose until the final prosthesis is made.
Still yet we find many people keep this type of appliance for many, many years, just like permanent ones because as long as they are properly maintained, they look outwardly as good as the more expensive permanent appliances. The one pictured above replaces 4 missing teeth, leaving spaces for 7 natural teeth. Two of the natural teeth are clasped with wrought wire clasps which are cured into the structure of the denture base.

The pink material of the denture base is hard plastic and the same material used to make complete dentures. The main single advantage to this type of RPD is the cost. Also the new teeth and new denture base can easily be added to an existing treatment RPD. These are frequently fabricated even if the remaining teeth have existing decay or periodontal disease and their prognosis is doubtful. If later in the course of treatment some of the existing natural teeth are extracted for any reason, new false teeth can be added quickly to the partial, maintaining the patient's appearance.

Another common and infact more important use of these appliances is as an "immediate partial denture". This means that the appliance can be made before the teeth are removed, and inserted immediately after the extraction of the planned teeth so that the patient is never without teeth. This is of special help when anterior teeth are to extracted and patient wants to return back to his/her normal routine immediately.

CAST METAL REMOVABLE PARTIAL DENTURE
These Removable Partial Dentures are cast metal frameworks made of chrome cobalt. These frameworks are cast to fit the teeth .These are cast very thin and are much less likely to break than the all plastic variety. For the same reason they are much less noticeable to the tongue.

The teeth have to be altered slightly beforehand in order that the partial denture can rest upon them without interfering with the way the patient bites the teeth together. Since they sit on the teeth, as well as being attached to them, they are extremely stable and retentive

The metal framework does not contact the gums. Thus, as the gums resorb, this type of partial does not sink with them and rarely requires relines.

Advantages

  • Rarely breaks. Can also be used for complete denture cases where breakage is
    a frequent problem.
  • It is made very thin, so less noticeable to tongue
  • More stable and retentive
