显微牙周外科技术在种植体周附着龈增宽术中的应用

ObjectiveThis study aimed to evaluate the clinical effect of periodontal microscopic surgery on the augmen-tation of attached gingiva and determined the clinical principle on how to use minimally invasive surgery to improve the surgery success rate.Methods Twenty patients with insufficient attached gingiva around implants were selected. Periodontal micros-copic surgery for free gingival graft was performed to increase the width of the attached gingiva around the implants. The survival state of the free gingiva was observed after surgery, and the width of the attached gingiva around the implants was recorded before and after surgery and 1 year after surgery. The shrinkage rate of the free gingival flap 1 year after surgery was analyzed to evaluate the stability of the flap.ResultsThe flaps of the 20 cases all survived. One year after the operation, the width of the attached gingiva was (3.05±0.44) mm, which increased compared with that of preoperation (2.56±0.31) mm and decreased compared with that of postoperative day (2.13±0.28) mm. The shrinkage rate of the attached gingiva was 41.22%±5.04%.ConclusionThe application of microscopic surgery on the augmentation surgery of attached gingiva can increase the success rate and improve the quality and quantity of attached gingiva around implants.
