Crown Lengthening With Palatal Roll Technique For Pink-White Harmony

This case report presents the clinical application of crown lengthening surgery combined with a palatal roll flap to restore buccal gingival soft tissue defects in the maxillary anterior region. A patient presented with a missing tooth 11 with a buccal gingival depression, residual roots of teeth 12 and 22, and a residual crown of tooth 21, with gingival inflammation extending from teeth 13 to 23. One week after initial periodontal therapy, crown lengthening surgery was performed. An internal bevel incision was made to remove granulation tissue, revealing a buccal bone defect at the site of tooth 11. Given the thick palatal gingival tissue, the connective tissue was then grafted beneath the buccal full-thickness flap through a palatal roll flap, successfully restoring the soft tissue contour and creating favorable conditions for prosthetic rehabilitation. For sites with persistent inflammation after initial periodontal therapy, an internal bevel incision can effectively remove granulation tissue while simultaneously reshaping the gingival margin to achieve symmetrical and natural morphology. The palatal roll flap technique utilizes the thickness of the palatal gingiva to provide adequate tissue volume for defect reconstruction. In cases of complex soft and hard tissue defects, it is clinically valuable to reasonably utilize local tissue resources to achieve pink-white harmony and functional rehabilitation after completely eliminating infection.
