Abstract
Maxillofacial deformities are characterized by alteration of various elements such as the maxilla, mandible, facial skeleton, and associated soft tissue structures. Deformities are divided into two categories: congenital and acquired. Acquired segmental mandibular defect causes significant morbidity; including appearance impairment, dysfunctional mastication, swallowing, speech, and has a negative impact on patients’ quality of life. Oral rehabilitation of patients with mandibular defects necessitates a multidisciplinary approach (1). The advancement of bone technology, osseointegration, microsurgery and improved dental prosthetics had revolutionized maxillofacial reconstruction. Briefly, the main goal of mandibular reconstruction is to restore the patient, previous state of function and form. Maxillofacial prostheses have a significant impact on the patient’s quality of life. Various materials, techniques, and clinical approaches have been used for maxillofacial prostheses (1). The conventional use of the metal clasp materials as cobalt chromium (Co-Cr), gold, stainless steel and titanium hinders esthetics. The disadvantages of metal clasped dentures are the added weight of the prosthesis, metallic taste and allergic reactions to metals, all of which contribute to the development of resin materials which enhance esthetics (2).
