Prosthodontic Management of a Patient with Moebius Syndrome: A Clinical Report

Abstract

Moebius/Mӧbius Syndrome (MS) is an extremely rare congenital disorder characterized by uni- or bilateral palsy of the abducens (VI) and the facial (VII) nerves, causing facial paralysis. Dysfunction of cranial nerves III through XII is common, most often the glossopharyngeal (IX) and hypoglossus (XII). Afflicted individuals seeking prosthodontic care, particularly removable prosthetics, present multiple challenges related to inherent facial and tongue muscle weakness and microstomia. Other extraoral anomalies may include congenital multiple arthrogryposis and malformations of the upper and lower limbs. This clinical report describes the rehabilitation of a patient with Moebius Syndrome using a maxillary 2-implant retained overdenture and mandibular partial removable denture prosthesis.
