Restorative Treatment of a Patient with an Oro‐Facial Developmental Disorder

Abstract

Restoring the edentulous patient with an implant fixed complete denture is a challenging procedure. The patient's occlusal vertical dimension, centric relation position, esthetics and phonetics must be maintained throughout the restorative process, while the patient is wearing a removable prosthesis. Using simple procedures, the complete dentures can be converted to fixed provisional restorations and provide valuable information to the clinician.Improper implant angulation is one of the most difficult problems to overcome in the fabrication of implant-supported and implantretained restorations. Different methods are used depending on the severity of angulation. Diagnostic procedures and proper treatment planning should minimize the incorrect placement of dental implants. However, when this does occur, esthetic and functional results can still be achieved. The various clinical and laboratory procedures for solving these problems will be presented.This study investigated the flexibility, recovery from deformation, and tear strength of 5 kinds of polyvinyl siloxane materials and evaluated their clinical relevance. Tests were performed in accordance with ADA/ANSI Specification No. 19 and modified trouser test for stretched materials. The results showed the new high-flexibility addition silicones had acceptable values of recovery from deformation and tear energy.
