Details and patient eligibility
About
Several surgical techniques have been proposed to correct recession defect and attain root coverage. Though, the majority were executed on Miller Class I and II recession defects. Moreover, Analysis of literature revealed only a few studies that treated miller class III recession defects.
In the current study, a new modification in the free gingival graft is proposed to provide the patient with more esthetic outcome, less pain and postoperative trauma. Likewise, the proposed graft modification will combined both FGG and CTG benefits, overcome the limitations of the FGG and enhances the advantages of CTG.
Full description
In the current study, patients with Miller's class III will be randomly allocated in two groups. In the first group, gingival recession will be treated by tunneling technique with subepithelial connective tissue graft (sCTG). the tunnel preparation will be performed in the recession site then the sCTG will be harvested from the palate and inserted in the prepared tunnel and sutured in a coronally advanced position.
Equally , the second group will be treated with modified free gingival graft (mFGG). Initially, after tunnel preparation in the recession site and harvesting of the free gingival graft,the proposed modification is performed by mimicking the recession defect shape and size leaving the rest of the free gingival graft deepithelialized and inserted in the prepared tunnel. then, suturing will be performed in a coronally advanced position.
