Removable partial denture

A partial denture prosthesis ( dentures ), short MOG is an affordable, aesthetically unsatisfactoy partial denture. Your metal framework (including the holding and supporting elements - so-called brackets) is made ​​of a chrome - cobalt -molybdenum alloy ( in technical jargon: Chro - Ko-Mo, consisting of 65 % Co, 30 % Cr, 5% Mo) in one piece cast. In this very stable scaffold the denture saddles are fastened with artificial teeth.

It is indicated as a standard of care in the loss of several teeth when fixed prosthesis is no longer possible and serves primarily the restoration of masticatory ( chewing), phonetic ( speech), and aesthetically - physiological (appearance and facial expression ) function. The denture is a removable dental prosthesis (so-called absolutely removable dentures ) and can therefore be cleaned outside the mouth. On the loss of other teeth, they can be extended in most cases. The elastic clips comprise the remaining natural teeth or crowns; the denture saddle rests on the alveolar ridge, causing the denture is usually worn periodontal ( on teeth ) and gingival / tegumental (on gums). The prosthesis should fit perfectly to exclude leverage and not to damage the rest of the dentition.

Planning

The aim is a Dentures, whose kinetics ( movement of the partial denture) is as low as possible. Elements, which influence the kinetics of the partial denture, the holding and supporting elements ( periodontal ) and the denture base ( tegument ). As a support zone areas of a tooth are called that pass the strain forces on the periodontium. Connecting two of these zones ( S2, S3 ) will give a thrust line, more than two zones ( S1 ), a supporting surface - the support polygon. A rotation axis is present when a force receiving area outside the support polygon is added. The axis is formed by the boundary line of the periodontal and tegumentalen areas. In periodontal / tegumental worn dentures is trying to lay to stressful Kauflächenanteile close as possible to the axis of rotation - eg by putting up the plastic teeth only to the first molar. In four- punk support ( by four brackets; without free-end ) no rotation axis is present, but only the support polygon formed from them.

Anchor teeth are set according to the remaining teeth and their value (dental condition). In edentulousness anchor teeth are set on each tooth limited portion. Switching saddle are usually always mesially and distally clamped ( in the anterior region for aesthetic reasons rather not ) - always free-end saddle away.

When holding elements are on offer:

  • Doppelarmklammer
  • Ring clamp
  • Bonwillklammer
  • Roach clip

Prostheses production

After the impression ( impression-taking ) of the patients teeth, a master model is established and articulated with the antagonist in an articulator. After measuring the working model with a parallelometer brackets and base or brackets are drawn and erased certain areas on the model. Now an investment model is made by doubling the output models, on which the metal framework is modeled from wax finished parts. After embedding the muffle is placed and heated until the model casting can be poured and then has to cool slowly in the preheating oven. Well done divesting, working out and the metal polish. The dentist will then receive the work of Framework try. Now the dental technician can finish on the scaffold the prosthesis with artificial teeth and plastic saddles from cold-curing resin.
