A STUDY OF SOFT TISSUE PROFILE CHANGES FOLLOWING MAXILLARY OSTEOTOMIES

Dr. Titus Peter, Dr. Abhilash Balakrishnan

Abstract :

PURPOSE OF THE STUDY: This study was done to investigate the two dimensional changes in the bone and the ratio of movements of overlying soft tissues in the upper lip region of the facial complex following maxillary osteotomies. MATERIALS AND METHODS: Preoperative and postoperative lateral cephalograms of patients who underwent maxillary osteotomy were taken. Soft tissue points (VB,SLS,Sn)were compared with the underlying hard tissue points (I &A)using constructed horizontal plane as the reference line. RESULTS: Soft tissue changes in relation to hard tissue changes noted in various lip regions were 0.801, 0.801&0.343 when points VB to I, SLS to A ,and Sn to A were compared respectively. CONCLUSION: The predictability and significance of changes of soft tissue in relation to hard tissue is variable as it reaches towards the nose. These ratios can be used for treatment planning to obtain predictable results
