Osteotomy-assisted surgical crown lengthening combined with edgewise orthodontics for deep bite and gummy smile correction: a 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
Introduction: Deep bite is a vertical occlusal discrepancy characterized by excessive anterior overlap, which may compromise dental esthetics, function, and structural integrity. An interdisciplinary approach integrating orthodontic therapy with periodontal crown lengthening can enhance tooth proportion and improve smile harmony. Case Presentation: A 24-year-old woman presented to the Oral and Dental Hospital of Universitas Gadjah Mada (RSGM UGM Prof. Soedomo), Yogyakarta, with complaints of anterior crowding, protrusion, deep bite, and a gummy smile. Clinical examination revealed a normal facial profile, a 3.63-mm overjet, a 6.7-mm overbite, and a Class I molar and canine relationship. Cephalometric analysis (SNA 83.17°, SNB 80.55°, ANB 2.63°) confirmed a Class I dentoskeletal pattern with bidental retrusion and mandibular anterior crowding. Discussion: Orthodontic treatment using a Standard Multiloop appliance effectively corrected the deep bite and aligned both arches, achieving a final overjet of 2.4 mm and an overbite of 2.0 mm. Subsequent crown-lengthening performed by a periodontics resident at the RSGM UGM Prof. Soedomo further refined gingival contours and enhanced smile esthetics. Conclusion: The integration of multiloop orthodontic mechanics and periodontal crown lengthening represents a predictable and comprehensive interdisciplinary strategy for managing deep bite with a gummy smile, resulting in significant improvements in occlusion, tooth proportions, and facial esthetics.
