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.
