STABILITY OF ANTERIOR MAXILLARY OSTEOTOMY USING MICROPLATES

Abstract

Introduction

Dentofacial deformity represents a great challenge faced by maxillofacial surgeons, maxillary protrusion, open bite,and /or deep bite can be corrected by anterior maxillary osteotomy however there is great controversy regarding stability of the osteotomized segment using different fixation system

Aim of the study

the aim of the study is to evaluate microplate fixation system for stability of anterior maxillary osteotomy.

Patients and methods

patients presented with maxillary protrusion were managed by anterior maxillary osteotomy using microplate system for fixation and all cases followed clinically and radiographically at least for one year

Results

Number of the patients was 12(11 females and one male ) all of the patients presented with maxillary protrusion that was corrected using anterior maxillary osteotomy , postoperative angular and linear measurements showed significant difference when compared with preoperative measurements , while there is no significant difference among all postoperative periods .also bone density increased gradually using gray scale measurement

Conclusion

Using microplate system for fixation of anterior maxillary osteotomy may lead to stable results with good bone healing and absence of palpability .
