Abstrakt: Objectives: The objective of this study is to minimize gingival display by surgical repositioning of the upper lip and to suggest this technique as an alternative treatment modality to orthognatic surgery for treatment of excessive gingival display.
Materials and Methods: Forty-eight patients were selected with gingival display of more than 2 mm during maximal smiling. All patients underwent surgical repositioning of the upper lip, aimed at limiting elevator muscle activity to treat excessive gum exposure. Patients were regathered in 1 week for the follow-up postoperative symptoms according to VAS scale to evaluate pain and swelling. Reference values were given to patients.
Results: The study has indicated good results and stability especially to patients with skeletal class I classification along with medium and thick biotype of attached gingiva without hypermobile upper lip.
Conclusion: Surgical repositioning of the upper lip is an effective way to improve a patient's gingival smile caused by degree I and II VME in combination with HUL as an alternative treatment modality to orthognathic surgery. This method is less invasive and cost-effective, causes minimal postoperative complications, and provides faster recovery.
Clinical Relevance: Excessive gingival display (EGD) with various etiologies requires several proper treatment modalities. The proposed modified method of lip repositioning to reduce the degree of gingival display is less aggressive, reliable, and causes fewer postoperative complications compared to orthognathic surgery.
