They lead to a dysfunction of the maxillofacial system and other functions like phonation, deglutition and mastication without a considerable impact on the aesthetic and the socio-psychological life of patients. Material and methods: This is a retrospective study that concerns patients who consulted El Farabi Regional Hospital and Mohammed VI University Hospital of Oujda during the period between 2010 and 2015. The aim of this study is to determine the frequency of maxillary and mandibular defects and to establish their epidemiological and clinical profiles in this region.

Results: The study of maxillary defects in Oujda indicate a prevalence of 68.75% with a male predominance (62%) and a mean age of 42 years old. 64.29% of had class II infrastructure maxillary defect according to the Bentahar classification. In the mandible, the prevalence was 31.30%; 53.52% of these mandibular defects were non-interrupted. The defects were mainly caused by tumors.
