Summary
Surgical management effectively corrects posttraumatic dysocclusion, often resulting from mandibular condyle fractures. Orthognathic surgery provides good outcomes for restoring normal occlusion after maxillofacial trauma.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
- Orthognathic Surgery
Background:
- Posttraumatic dysocclusion is a common complication following maxillofacial injuries.
- Mandibular condyle fractures are a primary cause of posttraumatic occlusal disturbances.
- Effective surgical management is crucial for restoring function and aesthetics.
Purpose of the Study:
- To evaluate the surgical management strategies for posttraumatic dysocclusion.
- To assess the outcomes of orthognathic surgery in patients with posttraumatic occlusal problems.
- To identify the most common causes and effective treatments for posttraumatic dysocclusion.
Main Methods:
- Retrospective review of patient charts from 1970-2012.
- Inclusion of 42 patients who underwent surgical correction of posttraumatic dysocclusion.
- Analysis of initial fracture treatments (conservative vs. ORIF) and orthognathic surgical techniques.
Main Results:
- Mandibular condyle fractures were the most frequent cause (64.3%).
- Sagittal split osteotomy of the mandible (50.0%) and Le Fort I osteotomy (40.5%) were the predominant orthognathic procedures.
- A variety of orthognathic surgical options were employed to correct the dysocclusion.
Conclusions:
- Posttraumatic dysocclusion frequently arises from mandibular condyle fractures but also from other maxillofacial fractures.
- Orthognathic surgery demonstrates successful outcomes in treating posttraumatic dysocclusion.
- Comprehensive surgical management is key to resolving occlusal disturbances after trauma.
