The Effect of Different Gingival Biotypes on Dimensional Stability of Free Gingival Graft

The Effect Of Different Gingival Biotypes On Dimensional Stability Of Free Gingival Graft: A Comparative 6 Month Clinical Study

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.

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.

Inclusion Criteria:

• In the mandibular incisor tooth / teeth, the attached keratinized gingival width is <1 mm,
• No periodontal surgery has been performed previously on the involved tooth.
• In the absence of any systemic condition or illness (pregnancy, breastfeeding, mental retardation, diabetes, etc.) that may interfere with the patient's approval and dental treatment.
• Do not use any of the drug groups that may cause gingival overgrowth.

Exclusion Criteria:

• Previous periodontal surgery in the operation area
• Restoration of the buccal surface of the tooth and no pathology in the apical region of the tooth.
• In the presence of any systemic condition or illness (pregnancy, breastfeeding, mental retardation, diabetes, etc.) that may interfere with the patient's approval and dental treatment.
