THE EFFECT OF FREE GINGIVAL GRAFT ON PERI-IMPLANT HEALTH

Abstract

Purpose:. The aim of the clinical study was to evaluate the width of keratinized tissue and periodontal parameters after free gingival graft procedure in implant supported prosthesis area and comparisons of the contralateral implant supported prosthesis area without keratinized tissue.

Methods: 15 patients with missing keratinized tissue in peri‑implant area participated in this randomized split mouth controlled study. Group I (test group) consisted of 15 patients receiving 15 free gingival grafts after implant‑supported prostheses. Group II (control group) consisted of the contralateral implant supported dentures of the same patients. Gingival recession depth (RD), keratinized tissue width (KTW), probing depth (PD), clinical attachment level (CAL) and gingival thickness (GT) were evaluated at baseline and after 12 months.

Results: Both groups showed absence of signs and symptoms of peri‑implant disease. The amount of keratinized tissue significantly increased 6 months after surgery in test groups. KTW and GT were increased in test groups from baseline to 6 months (p<0.001). PI and GI scores were found higher in control groups. In postoperative sixth month RD, PD and CAL were similar in the both group. In postoperative sixth month, KTW and GT was better in test group (p<0.001). RD, PD and CAL were similar in the both group.

Conclusions: The free gingival graft is an effective approach to increase the width of keratinized tissue of implant‑supported prosthesis. Lack of the peri implant keratinized tissue plays a critical role in the accumulation of bacterial plaque around the dental implants, this situation may increased risk of peri implant diseases.

SERBEST DİŞETİ GREFTİNİN PERİ-İMPLANT SAĞLIK ÜZERİNE ETKİSİ

Abstract

Amaç: Keratinize doku, sağlıklı peri-implant mukozanın idamesi için önemlidir. Bu klinik çalışmanın amacı, yapışık keratinize dişeti olmayan implant destekli protez bölgesine serbest dişeti grefti prosedürünün ardından keratinize doku genişliğinin, periodontal parametrelerin değerlendirilmesi ve keratinize doku olmayan kontrlaterel implant destekli protez alanındaki klinik parametreler ile karşılaştırılmasıdır. 

Gereç ve Yöntemler: Bu randomize kontrollü çalışmaya simetrik bölgelere yapılmış peri-implant alanında keratinize doku eksikliği bulunan 15 hasta katıldı. Grup I (test grubu), implant destekli protezlerden sonra implant bölgelerinden birine serbest dişeti grefti yapılan 15 hastadan oluşmaktaydı. Grup II (kontrol grubu), aynı hastaların müdahale yapılmamış kontrlateral implant destekli protezlerinden oluşuyordu. Her iki grupta dişeti çekilmesi miktarı (RD), keratinize doku genişliği (KTW), sondalama cep derinliği (PD), klinik ataçman düzeyi (CAL) ve gingival kalınlık (GT) başlangıçta ve 12 ay sonra değerlendirildi ve karşılaştırıldı.

Bulgular: Her iki grupta da peri-implant hastalığının belirtileri yoktu. Test gruplarında ameliyattan 6 ay sonra keratinize doku miktarı belirgin olarak arttı. KTW ve GT test gruplarında başlangıçtan 6 aya yükseldi (p <0.001). PI ve GI skorları kontrol gruplarında daha yüksek bulundu. Ameliyat sonrası altıncı ayında RD, PD ve CAL her iki grupta da benzerdi. Postoperatif altıncı ayda, KTW ve GT test grubunda daha iyi idi (p <0.001). RD, PD ve CAL her iki grupta benzerdi.

Sonuç: Serbest dişeti grefti proseduru peri-implant bölgede keratinize doku oluşturmak için en güvenilir yöntemdir. Keratinize doku eksikliği  peri-implant bölgede plak birikimine neden olmaktadır, bu durum peri-implant  hastalıkların oluşması için risk teşkil etmektedir.
