Mandibular reconstruction using a special plate: Animal experiments and clinical application

Abstract

The use of a variety of procedures and techniques for mandibular reconstruction suggest that no satisfactory solutions have been found with regard to restoration of functional stability, joint function and masticatory function. In view of the varied clinical problems involving restoration of mandibular function, we developed our own reconstruction plate, a condylar prosthesis, and a reconstruction plate with a condylar head. The U-shaped notches of the reconstruction plate permitted universal adaptation of the plates by means of special pliers. The most important result of the animal experiments was the achievement of stability under functional stress. This made intermaxillary fixation unnecessary. The preliminary experience in our clinical cases with the reconstruction plate showed a reduction of masticatory disability. The clinical results corresponded well with those of the animal experiments, and thus confirmed the value of the experimental model chosen.
