Aim: The aim of this study was to evaluate and compare conventional and modified lip repositioning surgical techniques used for management of gummy smile involving hyperactive lip elevator muscles. Methods and Materials.: A prospective study was conducted between April 2016 and May 2017. Twenty two adult patients aged 18-38 years with gummy smile ranging from 4 to 6 mm because of soft tissue disorders were included in the study. All patients were treated in the oral and maxillofacial department at Damascus University. The sample was divided into two groups of 11 patients. The first group was treated by the conventional standard technique, and the second group treated by a modified study technique. The amount of gingival display in full smile was evaluated in both groups following each intervention. Results: Both groups exhibited a statistically significant reduction in the measurement of gummy smile at month 1 and 6 postoperatively (P <.05), but there was no significant difference in gingival display at 3 months in either group postoperatively (P >.05). The recent study showed a significant difference in gingival display between 3 and 6 months postoperatively in group 1, but no significant difference in group 2. Conclusion: This study showed that the modified technique utilized in treating gummy smile has less relapse after surgery, shows excellent cosmesis and compared to the conventional technique, greater sustainability. Clinical significance: The recent increase in demand for an esthetic smile has led to the development a modification of conventional lip repositioning for correcting gummy smile by myotomy of lip elevator muscles. This modified technique offers less relapse and greater stability post-operatively than the conventional technique. © 2018 Wiley Periodicals, Inc.
