Oligodontia is the agenesis of 6 or more teeth, excluding third molars. The etiology of congenital absence of teeth is believed to be rooted in heredity or developmental anomalies. The absence of teeth in patients can cause aesthetic, functional, and psychological problems, particularly if the anterior region is involved. This case report describes the multidisciplinary treatment approach toward a patient 17 years of age with non-syndromic oligodontia, with absence of 11 permanent teeth. Genetic counseling revealed non-syndromic, autosomal-recessive-linked oligodontia. The objectives of the first phase of therapy were pre-prosthetic orthodontic space opening for proper positioning of the missing teeth and correction of inter-maxillary relations, as a prerequisite for proper prosthetic restoration. The second phase of therapy was prosthetic restoration of the missing teeth and provision of occlusion with full-mouth porcelain fused to metal crowns and bridges after increasing occlusal vertical dimension by 2 mm.
