Abstract

Conventionally, the intrusion of an abutment tooth in tooth-implant-supported xed partial dentures is a troublesome problem, especially in dentures with non-rigid connectors. The clinicians have previously reported that the intrusion of a natural tooth also can be induced when the natural tooth is bounded on both sides by an implant restoration. This unusual case report discusses the case of a 58-yearold female who suffered from infra-occlusion of the upper left first premolar following the sequential implantation of restorations over the adjacent canine and second premolar. In addition to the infra-occlusion, a 6 mm pocket and an angular bony defect on the mesial side of this tooth associated with a PDL widening, tight proximal contacts, and a mild percussion pain were noticed. In order to resolve the infra-occlusion, the old PFM restoration was removed and restored with a provisional crown with open interproximal and occlusal contacts. After one year of intensive and sequential adjustments of the proximal and occlusal contacts, the intrusion of the upper left first premolar was almost completely reversed and the periodontal defect was signi cantly improve.
