COMPARISON OF TWO DIFFERENT CROWN-LENGTHENING PROCEDURES

Background:Surgical crown lengthening procedure is done to increase the clinical crown length lost due to caries, attrition & fracture. In such cases before going for restorative treatment crown lengthening procedure has to be performed because violation of biologic width may compromise periodontal health. Several techniques have been proposed which includes gingivectomy by external bevel incision, flap procedure with osteoctomy& apically positioned flap with osteoctomy. Aim: To compare clinically two different surgical techniques of crown lengthening procedures: Group A - apically displaced flap with osteoctomy, Group B ? flap procedure with osteoctomy. Materials and methods:Fourteen patients who were advised CLP included & divided in two groups : Group A included patients who underwent apically displaced flap with osteoctomy& Group B included patients who underwent flap procedure with osteoctomy. Clinical measurements such as clinical crown length, width of attached gingiva, PPD, CAL & plaque index were taken at baseline and at 3rd month post‑operatively. Results & Conclusion: present study showed that there were no stastically significant differences in PPD, CAL in both groups. Clinical crown length is increased in both groups from baseline to 3 months. In group A where apically positioned flap with osteoctomy was performed width of attached gingiva was more at 3rd month from baseline.
