Lip Repositioning Surgery for Nonskeletal Excessive Gingival Display: A Clinical Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Excessive gingival display, or gummy smile, caused by upper lip elevator muscle hyperactivity presents a significant esthetic challenge. This case report details the successful management of a 28-year-old female patient with an objectively measured dynamic gingival exposure of 4 mm. Preoperative evaluations confirmed normal clinical crown dimensions and healthy periodontal tissues, definitively ruling out altered passive eruption. The patient underwent conventional lip repositioning surgery (LRS) featuring a partial-thickness mucosal excision and meticulous wound closure with 6-0 polytetrafluoroethylene (PTFE) sutures to mechanically restrict upper lip mobility. The dynamic gingival display decreased from 4.0 mm preoperatively to 1.0 mm at 2 weeks and was stably maintained at 1.5 mm at the 1-year follow-up, meeting the treatment success criteria (≤ 2 mm). The procedure established a harmonious dentolabial relationship with high patient satisfaction and no complications, such as severe scarring, labial paresthesia, or relapse. These findings demonstrate that, based on accurate differential diagnosis and strict case selection, LRS serves as a safe, minimally invasive, and highly predictable intervention yielding excellent short-to-medium-term esthetic outcomes for muscular hyperactive gummy smiles.
