Acase of maxillary prosthesis of the immediate reconstrucion of mandible.

Abstract

Immediate reconstruction of an edentulous mandible following excision of a mandibular cyst and odontoma was undertaken by combination of a reconstruction plate and a fresh autogenous iliac particulate cavernous bone. Nine months after the operation, an intra-oral prothesis was prepared in order to improve the masticatory function. Prosthetic management was aimed at by obtaining the maximum support and stability of the denture base and reducing the occulusal force. After wearing the prosthetic appliance, the masticatory function was evaluated by analyzing the mandibular movement,. masticatory electromyogram and masticatory efficiency. The results are summarized as follows:

No mandibular dislocation was found and a smooth mandibular movement was restored.In masticatory electromyographical analysis of the chewing cycie, high averages were obtained for the correlation coefficients of duration and duration per cycle on the recon-structed side.

The masticatory ability was evaluated by an experimental test food list for complete denture wearers and found to be as good as that for complete denture wearers.
