Supradentalna proteza – metodologija izrade

Abstract

Supradentalne proteze su zubne nadoknade koje se izrađuju preko prirodnih zuba ili njihovih korenova. Supradentalne proteze mogu biti: jednostavna imedijatna supradentalna proteza, supradentalna proteza koja je retinirana atečmenima i modifikovana postojeća parcijalna proteza. Cilj izrade supradentalne proteze je funkcionalna i morfološka rehabilitacija orofacijalnog sistema uz očuvanje rezidualnog alveolarnog grebena. Pre izrade supradentalnih proteza u zubotehničim laboratorijama neophodno je pripremiti zube koji služe kao oslonac protezi. Priprema se sastoji iz: selekcije zuba koji služe kao oslonac supradentalnoj protezi, izbora retencionih zuba i pripreme preostalih zuba. Nakon toga supradentalna proteza u laboratoriji izrađuje se kroz sledeće faze: anatomski otisak i model, pripremu anatomskog modela za izradu individualne kašike, izrada individualne kašike, funkcionalni otisak, pripremu funkcionalnog otiska za izlivanje radnog modela, zagrižajne šablone, određivanje međuviličnih odnosa, unošenje modela u artikulator, postava zuba, modelovanje proteze u vosku, kivetiranje, odstranjivanje voska iz kivete, proces polimerizacije akrilata, obrade i poliranja proteze.

Overdentures are dental restorations that are made over natural teeth or their roots. Overdentures can be: simple immediate overdenture, overdenture that has been retained by attachments and modification of an existing partial prosthesis. The goal of making overdentures is functional and morphological rehabilitation of the orofacial system while preserving the residual alveolar ridge. Before making overdentures in dental laboratories, it is necessary to prepare teeth that serve as a support for dentures. The preparation consists of: selection of teeth that serve as a support for the overdenture, selection of retention teeth and preparation of the remaining teeth. Afterwards, the overdenture is made in the laboratory through the following phases: anatomical impression and model, preparation of anatomical model for making individual spoon, making individual spoon, functional impression, preparation of functional impression for pouring working model, care templates, determination of intermaxillary relations, model insertion in the articulator, tooth placement, wax denture modeling, cuvetting, wax removal from cuvette, acrylate polymerization process, denture processing and polishing.
