The main techniques for covering denuded tooth surfaces are laterally positioned flaps, coronnally positioned flaps, oblique positioned flaps, double papilla flaps, free gingival grafts, subepithelial connective tissue grafts and gingival unit grafts. The mucosa surrounding the oral space is named palatal mucaosa and is the main donor site for free gingival graft and subepithelial connective tissue graft procedures. There is different ways to determine the thickness of palatal mucosa. Conic Beam Computerised Tomography CBCT has become a handfull technology as it can help making milimetric measurements and obtain highly diagnostic datas. When planning the procedures harvesting grafts from the palatina, CBCT gives datas of the graft dimensions. In this retrospective study, CBCT images of 50 women and 50 men are used. In the crosssection view the thickness of palatal mucosa of 1st premolar, 2nd premolar, 1st molar and 2nd molar teeth were measured. And from the cross-section image of second molar tooth the palatal depth and palatal angle. When measurements were analyzed, statistically no signifficant difference were found regarding between palatal mucosa thickness values for men and women. And the region between first premolar and first molar teeth was found to be the most suitable graft area.

Öz

Açığa çıkmış kök yüzeyinin kapatılması için kullanılan tekniklerin başlıcaları laterale pozisyone flep LPF , koronale pozisyone flep KPF , oblik pozisyonlandırılan flep, double papilla flep DPF , serbest dişeti grefti SDG , subepitelyal bağ dokusu grefti SBDG , dişeti ünitesi grefti DÜG ve yönlendirilmiş doku rejenerasyonu olarak sayılabilir. Damak olarak bilinen ağız boşluğu tavanını kaplayan mukoza palatinal mukozadır ve SBDG ve BDG işlemlerinde greft alınması için sıklıkla tercih edilmektedir. Palatinal mukoza kalınlığının ölçülebilmesi amacıyla farklı teknikler kullanılabilmektedir. Konik ışınlı bilgisayarlı tomografi KIBT teknolojisi hekime milimetrik düzeyde inceleme ve yüksek diagnostik kalitede bilgiler sağlaması nedeniyle diş hekimliğinde artık gerekliliği kanıtlanmış bir yöntem haline gelmiştir. Damaktan yumuşak doku grefti alınmasını gerektirecek prosedürlerin planlanması aşamasında uygun miktarda greftin elde edilebilmesi açısından konik ışınlı bilgisayarlı tomografi incelemesi yapılması önemli bilgiler sağlayabilmektedir.
