Orthodontic extrusion of teeth under fixed partial dentures: A case report

Objective: The purpose of this case report is to provide a simple forced eruption technique to recover a decayed canine that was a primary abutment for a fixed partial denture (FPD). After an analysis of casts on an articulator, a forced eruption technique was applied, using the old FPD as a bracket to apply the extrusion force on the root of the canine. After 6 weeks, the desired 5-mm extrusion was achieved, maintaining the old FPD in its original position. This simple procedure has many advantages compared with the traditional root extrusion techniques. The use of the old FPD allowed preservation of esthetics and function, better application of the eruption force, guided extrusion of the tooth, and reasonable stabilization time.
