Alt ve Üst Çene Tam Dişsiz Hastalarda Rezidüel Kret Genişliğinin Değerlendirilmesi

Abstract

Diş çekiminden sonra, alveolar kemik genişliğinin yanı sıra yüksekliğini de içeren belirgin değişikliklere uğrar. Maksilla veya mandibulada diş kaybından sonra alveolar kemiğin rezorpsiyonu genel olarak üç boyutlu gerçekleşmesine rağmen, horizontal kemik kaybı ile vertikal kemik kaybı oranlarının farklı olduğu gösterilmiştir. Son zamanlarda, konik ışınlı bilgisayarlı tomografi (KIBT), alveolar kemik rezopsiyonlarının değerlendirilmesinde yaygın olarak kabul edilen bir tanı aracı haline gelmiştir. Bu çalışmada, alt ve üst tam dişsiz hastalarda KIBT görüntülerinde rezidüel kret genişliğinin değerlendirilmesi amaçlanmıştır. Çalışmaya implant değerlendirmesi için KIBT alınmış, alt ve üst tam dişsiz çenelere sahip ve diş çekimlerinin üzerinden en az üç yıl geçmiş 50 hasta dahil edilmiştir. Çalışmada alt çenede kretin en dar ve en geniş olduğu bölgedeki ölçüm, üst çenedeki kretin en dar ve en geniş olduğu bölgedeki ölçümden daha büyük bulunmuştur (p<0,05). Total dişsiz çenelerde kret genişliğinin en az ve en geniş olduğu bölgelerin bilinmesi, dental implant planlamalarında ve tedavisinde başarıyı arttıracaktır.

Evaluation of Residual Crest Width in Patients with Total Edentulous Lower and Upper Jaw

Abstract

After tooth extraction, the alveolar bone undergoes explicit changes, including the height of the bone as well as its width. Although resorption of the alveolar bone after tooth loss in the maxilla or mandible is generally three-dimensional, it has been shown that the rates of horizontal bone loss and vertical bone loss are different. Recently, cone beam computed tomography (CBCT) has become a widely accepted diagnostic tool for the evaluation of alveolar bone resoptions. In this study, it was aimed to evaluate the residual crest width in cone-beam computed tomography images in upper and lower edentulous patients. In the study, 50 patients who had edentulous upper and lower jaws and at least three years past after tooth extraction were included in the study. In the study, the measurement in the region where the crest is the narrowest and the widest in the mandible was found to be greater than the measurement in the region where the crest is the narrowest and the widest in the maxilla (p<0.05). Knowing the areas where the crest width is the narrowest and the widest in total edentulous jaws will increase the success in dental implant planning and treatment.
