The occlusion establishment in panfacial fracture

Introduction: It is difficult to establish the normal occlusion in some cases of panfacial fracture due to the lack of reference basis caused by displacement of maxilla and mandible at the same time.

Purpose: The aim of this study is to conclude our experience in occlusion establishment for panfacial fracture.

Material and method: Totally 45 panfacial fracture cases of Stomatological Hospital, China Medical University were retrospectively evaluated. The model surgery had been performed before operation, and the Wafer had also been prepared for reduction during this procedure. Open reduction and internal fixation were used in these cases. Accurate reduction of zygomaxillary complex and reconstruction of condyle and ramus were the key points for reconstruction of facial height and avoidance of postoperation open bite. The reduction of mandible and maxilla as well as the rebuilding of dental arch had been performed according to the Wafer. It was emphasized that the change of the width of dental arch should be avoided in sagittal maxilla fracture and bilateral condyle fracture combined with symphyseal fracture. All the patients were instructed functional exercises 2-3 weeks after operation.

Results: The stable and functional results were obtained after 3-6 months follow up.

Conclusion: It can be concluded from this investigation that the occlusion in panfacial fracture should be established in three dimension. Model surgery and Wafer fabrication should be performed before operation.

Conflict of interest: None declared.
