Hinweis der Redaktion
- Previously, teeth in the fracture line have been universally condemned in most cases of maxillary and mandibular fracture repair. Iatrogenic dental trauma and extractions of teeth were commonplace. Extracting such teeth creates complications due to the disruption of the blood supply and iatrogenic trauma to the soft tissues. Further displacement of the fracture fragments, elimination of occlusal landmarks, elimination of available structures for fixation, and creation of large bony defects all can adversely affect fracture healing. Preservation of the teeth involved within the fracture line contributes to proper anatomical alignment and the ultimate stability of the fracture.3 Specifically, a tooth in the line of fracture, that has no evidence of severe mobility, should be retained if it aids in preventing displacement of the bone fragment in which it resides. Teeth with fractured roots or extensive periodontal disease should be extracted. Teeth with fractured crowns can be retained if emergency endodontic therapy (vital pulpotomy) is performed. Extractions or further endodontics and/or restorations can always be performed at a later date if these teeth create subsequent problems. Avulsed or luxated teeth should be re-implanted immediately, but usually require endodontic intervention at a later date. Pathologic fractures secondary to severe periodontal disease usually occur in the mandible and often present with significant bone loss. The osteolysis and osteitis inhibit fracture healing and result in poor bone quality for holding fixation devices. The primary goal is function. Salvage options may include mandibulectomy or commissurorrhaphy.
