Use of a resorbable fixation technique for maxillary fractures

Area of Science:

• Oral and Maxillofacial Surgery
• Biomaterials Science
• Orthognathic Surgery

Background:

• Maxillary fractures, particularly LeFort I, require stable fixation for optimal healing.
• Traditional metallic fixation devices can lead to complications.
• Resorbable polymers offer a potential alternative for rigid fixation.

Purpose of the Study:

• To evaluate the efficacy of nonmetallic rigid fixation using resorbable polymers for isolated maxillary (LeFort I) fractures.
• To compare intraoperative stability and long-term outcomes with this novel fixation method.

Main Methods:

• A prospective study involving 11 patients with isolated LeFort I fractures.
• Utilized resorbable plates and screws composed of poly L-lactic acid and polyglycolic acid for fixation.
• Assessed intraoperative stability and long-term postoperative results.

Main Results:

• No significant differences in intraoperative maxillary stability were observed.
• Long-term postoperative results were comparable to those achieved with traditional fixation methods.
• Effective fixation was achieved when good, noncomminuted bone was available for screw placement.

Conclusions:

• Nonmetallic rigid fixation with resorbable polymers is a viable option for LeFort I fractures.
• The technique provides stable fixation and satisfactory long-term outcomes in selected patients.
• Adequate bone stock is crucial for successful application of this resorbable fixation system.
