Prospective case series evaluates surgical accuracy and patient satisfaction in excessive gingival display treatment.

Key Points

This research aims to assess the effectiveness of a digital workflow for treating excessive gingival display from altered passive eruption.
Enrollment of 30 patients diagnosed with APE Type 1B.
Use of cone-beam computed tomography and intraoral scanning for treatment planning.
Fabrication of a 3D-printed double surgical guide for gingivectomy and osteotomy.
Assessment of surgical accuracy and clinical outcomes at 6 months post-treatment.
Median gingival margin relapse of 0.69 mm at 6 months.
Significant reduction in gingival display, decreasing from 3.13 mm to 1.06 mm (p < 0.001).
Notable increase in clinical crown length from 7.64 mm to 10.00 mm (p < 0.001).
100% patient satisfaction reported regarding the esthetic outcomes.
