Purpose
To report a predictable minimally invasive treatment approach for a gummy smile patient by using laser-assisted guided gingivectomy and lip repositioning.
Background
Excessive gingival display is one of the most common esthetic concerns that might affect the patient’s psychology and social life, especially in young age. For a long time, orthognathic surgery was recommended in spite of its high morbidity. Lip repositioning was the treatment of choice for many patients as it was effective for the reduction of gingival display, a safe and less invasive procedure. Although, due to the multifactorial origin of gummy smile, combined treatment protocols are usually required. Besides, the patients demand reduced pain following procedures as well as predictable outcomes.
Case report
A 20-year-old male patient was requesting a treatment for his gummy smile. Upon examination, 7-mm gingival display was reported with a multifactorial origin. A 3D-printed computerized gingivectomy guide was fabricated based on the smile design for the patient by using the cone beam computed tomography, extraoral and intraoral photographs. A 940-nm diode laser in a continuous wave mode and with a power of 1.5 W was used for the gingivectomy and lip repositioning. The procedure was performed under local anesthesia with no bleeding or post-operative complications reported.
Conclusion
The combined treatment approach by using computer-guided gingivectomy and lip repositioning by using 940 diode laser was effective to provide predictable outcomes for treatment of gummy smile with minimal bleeding, uneventful healing, and minimal postoperative pain.
