Summary

The aim of this study is to compare the effect of mesial and distal adjacent gingival biotypes of the tooth / teeth region of free gingival graft (FGG) on the shrinkage ratio of graft at 6 months postoperatively.

Detailed description

The concept of gingival and periodontal phenotype was established as a result of clinical observation of changes in facial keratinized tissue width and thickness .It has been reported that gingival or periodontal diseases may develop more frequently in patients with thin gingival biotypes and that thick-flat biotype in implant restorations is important in achieving a successful aesthetic treatment outcome. Free gingival graft (FGG) is a mucogingival surgical procedure that is successfully used in the presence of inadequate keratinized gingival width and gingival recession. It is thought that factors that may adversely affect the continuity of graft nutrition may be effective in graft shrinkage. These reasons can be listed as follows; graft thickness, traumatic surgical procedure, graft dehydration, and suturing procedure. There was no study investigating the effect of periodontal biotypes on graft contraction in the region adjacent to the FGG operation.

Conditions

• Gingival Recession
• Atrophy

Interventions

Type	Name	Description
PROCEDURE	free gingival graft	A horizontal incision was made along the mucogingival line with a scalpel number 15 to prepare a bed of periosteum and a thin immobilized connective tissue. The moving gingival tissues were removed coronally, and the bed was prepared so that the immobilized keratinized gingival tissue was preserved and the graft was placed apically. The template of the recipient region was placed in the donor region to be 2-3 mm more apically than the gingival margins of the teeth. The number of 15 scalpel was used to make incision at the template border and perpendicular to the keratinized tissue. The graft thickness was standardized in all patients between 1.5-2 mm. FGG was placed over the recipient bed and 5/0 non-resorbable monofilament sutures were used for fixing the four corners of the graft.
