An Orthodontic Study of Non-syndromic Oligodontia: An Examination of Occlusion and Occlusal Support.

The aim of this study was to analyze orthodontic data to investigate occlusal conditions, the relationship between malocclusion and the number of congenitally missing teeth, and occlusal support of maxillomandibular teeth in patients with oligodontia. The study included 66 patients with permanent dentition from two orthodontic clinics belonging to Tokyo Dental College who had received a diagnosis of oligodontia between 2003 and 2014. The materials used for the analysis comprised intraoral photographs, panoramic radiographs, and lateral cephalometric radiographs.
