TOTAL PROSTHESIS

Even though great advances have been made in tooth restoration and implantology in the last decades, total prostheses are still used very often.
Classical total prostheses consist of a collection of removable teeth that are supported by the oral mucosa. The prosthesis is kept in place by suction on the oral mucosa, rather like a suction pad.
A total prosthesis consists of a suction plate made of plastic, to which the replacement teeth are added. The prosthetic teeth are also made of plastic and sometimes have a ceramic shell.
There are several important aspects to the planning and construction of a total dental prosthesis: impression (of the teeth), bite registration, function and aesthetics.

  • Impression

    In order to guarantee the functional quality of the total prosthesis, the bite must be accurately depicted and recalibrated depending on the situation. The bite height, which usually falls after teeth are lost, is particularly important, and so is the position of the upper and lower jaw with respect to one another. The bite position can be determined by the dentist using wax walls on a bite plate. This requires a lot of experience and intuition. The dentist guides the jaw and mandibular joint into the correct position, avoiding the risk of complaints later on.

  • Aesthetics

    Now the teeth can be assembled. Just as natural teeth come in many different forms and colors, so can replacement teeth be manufactured differently to ensure they closely resemble the original teeth.

  • Prosthesis stability and chewing comfort

    Even with the best possible quality and workmanship, problems can still occur with prosthesis stability and chewing. Many people find covering the palate in the upper jaw with plastic uncomfortable and disruptive to taste. “Palate-free” treatment in the upper jaw usually requires at least four, preferably 6, implants.
    The anatomy of the lower jaw is more complicated and the form of the bone in the lower jaw often interferes with a satisfactory maintenance of the prosthesis. In such cases, prosthesis stability can be achieved by the use of two or four implants.

PARTIAL PROSTHESES

Partial prostheses replace single or multiple teeth and are supported by a metal scaffold. Often, partial prostheses are anchored onto crowns by supporting elements called clamps. This allows a precise fit of the denture while preventing the development of caries underneath the prosthetic clamp. Partial prostheses are an important treatment option when dentures can no longer be fixed onto the patient’s own teeth, or the patient cannot receive implants for medical reasons. A good fitting of the dentures can be achieved by the incorporation of onlays secured by clamps. The denture framework is generally made out of metal alloys. For patients with an intolerance or allergy to metal, the denture framework can be manufactured using high-performance plastic.
