Simplified Fabrication of a Lingual Splint for Management of Mandibular Fractures

Abstract

Summary: Lingual splints have been used to treat mandibular fractures, particularly in cases of complicated mandibular fractures, and serve as a noninvasive adjunctive procedure for reduction and fixation. Furthermore, when used in conjunction with open reduction and internal fixation, the lingual splint provides feasible external fixation against displacing forces exerted by the robust musculature of the mandible. However, the conventional method for lingual splint fabrication is performed preoperatively, and the procedure is time-consuming. This technical note describes a simplified and efficient technique for the intraoperative manufacture of a lingual splint for mandibular fractures using a thermoplastic material, polycaprolactone. Our results demonstrated satisfactory fixation outcomes, reduced lingual splint fabrication time, and superior cost-effectiveness, offering an alternative option for adjunctive external fixation of mandibular fractures.
