Aim: The present study was carried out to evaluate the efficacy of laser-assisted lip repositioning for gummy smile correction.

Materials and methods: This was a prospective study with sample size of 10 patients with a gummy smile of more than 3 mm. Clinical assessment of pre- and postoperative lip length at rest and at smile was done. Analysis of variance (ANOVA), Tukey test and Chi-square test were used for statistical tabulation.

Results: On assessing, the mean value of pre-op gingival display was 5.4 mm , postoperative 6 months showed a mean value of 1.9 mm The results were statistically significant. Measurement of lip length showed pre-op mean value of 19.20 mm at rest and 14.20 mm at smile; postoperative results at 6 months was estimated at 20.1 mm at rest and 15.7 mm while smiling, p=0.460 lip length at rest and p= 0.082 lip length at smile.

Conclusion: It is an efficient technique for correction of gummy smile and an excellent alternative to more costly procedures with high morbidity rates. It is also minimally invasive with minimal postoperative swelling and pain. But extensive research is definitely imperative so as to increase its range of application.
