Abstract

A mucogingival grafting procedure has been developed to cover denuded root surface. The subepithelial connective tissue graft technique is very predictable and allows for a good esthetic results and minimum patient discomfort on the palate.
However, in areas where there is a lack of vestibular depth and keratinized attached tissue, the presence of frena or heavy muscle attachment, covering the connective tissue graft with a mucosal flap is very difficult. The purpose of this study is to evaluate an alternative technique of root coverage using the free connective tissue graft.
The results were as follows:
1. Probing depths didn't seem to vary significantly from the preoperative to postoperative period.
2. The amount of keratinized tissue showed an increase of 5.9±0.97mm from the preoperative level.
3. Total clinical exposed root coverage increase 72.2% compare with preoperative level.
4. The shrinkage from gingival margin is 4.2±1.15mm and the mean shrinkage rate is 40.1%.
5. The depth of the vestibule increased with the average distance from cementoenamel junction to mucogingival junction being 7.4±1.65mm.
