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.
