Measuring the Influence of Maxillary Obturator Prosthesis on Facial Morphology in Patient With Unilateral Maxillary Defects Using Stereophotogrammetry

Functional rehabilitation and quality of life after maxillofacial surgery have been emphasized in recent years. It depends mainly on outcomes of maxillofacial reconstruction and rehabilitation involving functions, esthetics, psychology acceptance and resocialization.

Tooth loss, alveolar and maxillary bone resorption or changes of the hard palate cause facial asymmetry in patient with maxillofacial surgery. The facial soft tissue over the defect become recessed as a result of loss of lip and buccal support which lead to decrease the quality of life and psychological disorders. Prosthetic intervention with maxillary obturator prosthesis is necessary to restore the contours of the resected palate and to recreate the functional separation of the oral cavity and sinus and nasal cavities. The purpose of this study is to investigate the influence of maxillary obturator on facial morphology in patient with unilateral maxillary defect by using 3 dimensional digital stereophotogrammetry compared to the intact side of the same patient
