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.
