A SIMPLIFIED IMPRESSION TECHNIQUE FOR DISTAL EXTENSION REMOVABLE PARTIAL DENTURES

The construction of a removable partial denture in distal extension cases is a delicate procedure since the prosthesis is supported by two different tissues, namely teeth and mucosa. The different resiliency of these supporting tissues may lead to the instability of the prosthesis. This paper describes a functional impression technique that aim to equalize the masticatory load between teeth and edentulous areas thus reducing the instability of the partial denture during function and preserving the residual teeth. Resume La construction d’une prothese amovible partielle en cas d’extension distale est une procedure delicate car la prothese est supportee par deux tissus differents, a savoir les dents et les muqueuses. La resilience de ces differents tissus de soutien peut conduire a l’instabilite de la prothese. Cet article decrit une technique d’empreinte fonctionnelle qui vise a equilibrer la charge masticatoire entre les dents et les zones edentees, reduisant ainsi l’instabilite de la prothese partielle au cours de la fonction et la preservation des dents residuelles.
