Multidisciplinary Management of a Fractured Premolar: A Case Report with Followup

Abstract

The general dental practitioner must consider orthodontic extrusion of a tooth when a subgingival defect, such as, crown fracture occurs before prosthetic rehabilitation, especially in the aesthetic zone. Extrusion enables the root portion to be elevated which exposes sound tooth structure for placement of restorative margins. This case report describes the multidisciplinary management of a fractured upper first premolar in a general dental practice. The forced orthodontic eruption is achieved by an endodontic attachment and sectional fixed appliance with an offset placed in the wire. The ability to extrude premolars with this method is complicated by heavy occlusal forces, occlusal interferences, and short clinical crown length. The tooth was restored with a titanium post, composite core, and porcelain fused to metal crown. The entire course of treatment was carried out under National Health Scheme, UK and as a part of vocational training. The 21 months followup showed no change in occlusal contacts or gingival level.

Orthodontic Extrusion as an Aid for Restoring Extensively Destroyed Teeth and Preserving Implant Site Creation: A Case Series

“…10 Also, orthodontic extrusion may represent a valid option for clinicians in different clinical situations as it results in improvement in the vertical amount of both hard and soft tissues. 11 Recently, Graf et al investigated surgical crown lengthening through clinical observations. They noted low biological complication rates in the surrounding periodontal tissues and periapical regions over the follow-up period, and during provisional treatment and after the delivery of the final crown.…”
