Intermaxillary fixation (IMF) screws offer a viable alternative for treating mandibular fractures. While effective, iatrogenic dental root injury is the primary complication, manageable with surgical expertise.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Traumatology
Background:
- Evaluating the efficacy of intermaxillary fixation (IMF) screws in managing mandibular fractures.
- Assessing IMF screws as an alternative to traditional methods for fracture stabilization.
Purpose of the Study:
- To determine the effectiveness of IMF screws in treating mandibular fractures.
- To identify complications associated with IMF screw use.
Main Methods:
- Retrospective analysis of 200 patients with mandibular fractures treated with IMF screws.
- Pre and postoperative panoramic radiography.
- Clinical assessment of adjacent teeth vitality, mobility, and iatrogenic injuries.
Main Results:
- Iatrogenic damage to dental roots was the most significant complication observed.
- Screw-related issues like loss, breakage, or mucosal coverage were also noted.
- Postoperative occlusion was evaluated.
Conclusions:
- Intraoral cortical bone screws for IMF represent a valid treatment option for mandibular fractures.
- Minimizing iatrogenic dental root injury is crucial and achievable with experienced surgical application.
