Three Dimensional Soft Tissue Analysis Of Skeletal Class III Patients After Bimaxillary Orthognathic Surgery Using Laser Surface Scanner

Abstract

Objective: The purpose of this study was to assess the effect of bimaxillary orthognathic surgery on the short-term soft tissue changes
of facial structures using a laser scanner for 3D facial acquisition.
Materials and methods: Thirty patients were selected for this study with skeletal class III malocclusion that required bimaxillary
orthognathic surgery
A Le Fort I maxillary advancement with or without maxillary impaction and a bilateral sagittal split osteotomy were performed. 3D
acquisition of the craniofacial structures was obtained by Planmeca ProMax® laser surface scanner, preoperatively and postoperatively
after 6 months.
Result: These scans were superimposed over each other and was analyzed by the color-coded map. Bimaxillary orthognathic surgery
resulted in soft-tissue changes that were maximized in the central parts of the face than in the lateral parts.
Conclusion: The color-coded analysis provides a better understanding of the three-dimensional soft tissue changes.
