ABSTRACT
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. (Eur J Dent 2012;6:218-226)
