Comparative evaluation of management of gingival recession using subepithelial connective tissue graft and collagen membrane by periodontal microsurgical technique: A clinical study of 40 cases.

BACKGROUND

New technologies, instruments, and surgical techniques are necessary to help the clinician ensure the best result and satisfy the patient's expectations, and surgical microscope has been thoroughly demonstrated as a useful tool. A clinical study was carried out to compare 2 different types of root coverage procedures using periodontal microsurgical procedure.

MATERIALS AND

METHODS

Forty patients were selected and divided into Group A and Group B. Group A subjects were treated with subepithelial connective tissue graft (CTG) whereas Group B subjects were treated using a resorbable collagen membrane. The procedures were performed with the help of an operating microscope using 250 mm objective lens and ×6 magnification.

RESULTS

A comparison between baseline, 1, 3, and 12 months have been done between groups among all parameters. It has been noticed that the root coverage was better in Group A subjects at all time. At 12 months, Group A showed 81.42% coverage where in Group B it was 70.08%. Similarly, increase in the width of keratinized gingiva and attached gingiva were more in Group A.

CONCLUSIONS

The present study showed that use of microsurgical instrument helped to deliver precise incision, better visual acuity, and improved illumination which facilitate to gain a better final outcome. Root coverage was better in the patients using CTG.
