简要总结
Free gingival graft is a mucogingival surgical technique applied to increase keratinized gingival width and reduce gingival recession. Free gingival graft is one of the most widely used approaches in root closure treatments and in increasing the height of the keratinized gingiva. Evaluation of the effect of the amount of creeping attachment on the root surface caused by the free gingival grafts placed coronally and apical to the mucogingival line on the gingival recession in the mandibular anterior region with keratinized gingival deficiency with gingival recession. Forty patients with gingival recession and insufficient keratinized gingival height will be randomly divided into 2 main groups as free gingival grafts to be placed coronal and apical to the gingival recession.
详细描述
Free gingival graft is a mucogingival surgical technique applied to increase keratinized gingival width and reduce gingival recession. Free gingival graft is one of the most widely used approaches in root closure treatments and in increasing the height of the keratinized gingiva. The "creeping attachment" phenomenon draws attention in the long-term success of root closure treatment in areas with gingival recession. "Creeping attachment" is defined as the coronal movement of the gingiva in the area where free gingival graft or connective tissue is applied in the postoperative period. The mean root closure rate with the creeping attachment is approximately 1 mm and can be detected 1 to 36 days after graft surgery. In the literature, clinical studies that measured a creeping attachment value between 0.12 and 3.5 mm in a 2-year period in free gingival grafts applied to the marginal gingival level have been reported.
Systemically healthy and non-smoking patients older than 18 years of age who applied to Kütahya Health Sciences University, Faculty of Dentistry, Department of Periodontology and had gingival recession in mandibular anterior teeth and keratinized gingival deficiency will be included in the study. Systemic and dental anamnesis will be taken from the patient before the operation and clinical measurements will be recorded.
Patients will be divided into 2 main groups as free gingival grafts to be placed coronal and apical to the gingival recession. They will be written as Group I and Group II in sealed envelopes and apical and coronal positioning groups will be chosen randomly.
The operation date will be given after the patient is given oral hygiene training and 4 weeks after receiving Phase I routine periodontal treatment. The data to be obtained preoperatively and postoperatively are as follows:

结局指标
主要结局
1. Percent closure of the gingival recession
时间窗: Postoperatively 1th month, Postoperatively 3th month, Postoperatively 6th month, Postoperatively 12th month
It is calculated by dividing the pre- and post-surgical values of the exposed root surface.
