Abstract

Background: It
is necessary to evaluate the alveolar bone topography and adjacent anatomical
structures to reduce the complication and augmentation rate in implant
placement. In this study, the location and depth of the buccal crest concavity
in the anterior maxilla were evaluated by cone-beam computed tomography (CBCT).

Methods: All
CBCTs in the pool were examined with the exception of patients with full
edentulous. The area of the buccal concavity place and deepness were measured
in three dimensions by the features of tomography software.

Results: In
this study, the incidence of buccal concavity was 23.3% in central, 44.3% in
the lateral and 26.4% in the canine of right maxilla; 20.3% in central, 47.1%
in the lateral and 18.3% in the canine of left maxilla. The lateral teeth have
the most buccal concavity rate. The location of the buccal concavity was found
to be the right central (7.63 mm) and left central (8.06 mm) as the teeth with
the most distance to the alveolar crest. The depths of buccal concavity were
found to be shallowest in right canine (1,41 mm) and left canine (1,54 mm). No
statistically significant difference was found between the age, right-left
symmetry and gender in terms of the location and depth of the buccal concavity.

Conclusions: Within
in the limits of this study, the risk of complication and the need for
augmentation in the implant operations are higher at the lateral, whereas the
canine is considered safer.

ANTERİOR MAKSİLLER BÖLGEDEKİ BUKKAL KONKAVİTELERİN ANALİZİ: RETROSPEKTİF KONİK IŞINLI BİLGİSAYARLI TOMOGRAFİ ÇALIŞMASI

Abstract

Amaç: İmplant operasyonlarında komplikasyon riski ve ogmentasyon
gerekliliği oranını azaltmak için alveoler kemiğin topografisinin, komşu
anatomik yapıların ayrıntılı olarak değerlendirilmesi gerekmektedir. Bu çalışmada,
anterior maksilla bölgesindeki bukkal kret konkavitesinin yeri ve derinliği konik
ışınlı bilgisayarlı tomografi (KIBT) kullanılarak incelenmiştir.

Gereç ve Yöntemler: Sağ ve sol maksilla anterior bölgede kısmi ya da tam dişli
hastaların KIBT görüntüleri taranmıştır. Anterior dişlerin kesitsel görüntülerinde
milimetrik ölçümler yapılmıştır. Bukkal konkavite yeri ve konkavite derinliği üç
boyutlu olarak ölçülmüştür.

Bulgular: Bu çalışmada bukkal konkavite görülme oranı sırasıyla sağ
maksillada santralde %23,3, lateralde %44,3 ve kaninde %26,4; sol maksillada
santralde %20,3, lateralde %47,1 ve kanin bölgesinde %18,3’tür. Sağ ve sol
lateral dişler en fazla bukkal konkavite oranına sahip dişlerdir. Bukkal
konkavitenin yeri alveoler kret tepesine en uzak dişler 7,63 mm ile sağ santral
ve 8,06 mm ile sol santraldir. Bukkal konkavite derinlikleri en sığ dişler
ortalama 1,41 mm ile sağ kanin ve ortalama 1,54 mm ile sol kanin olarak
bulunmuştur. Bukkal konkavitenin yerinin ve derinliğinin yaşa, sağ-sol
simetrisine ve cinsiyetlere göre yapılan karşılaştırmalı değerlendirme
sonucunda istatiksel olarak anlamlı fark bulunamamıştır.

Sonuçlar: Bu çalışmanın limitasyonları dahilinde, implant
operasyonlarında lateral dişler cerrahi komplikasyon oranı ve greftleme
gerekliliği açısından daha yüksek riske sahipken kanin dişler daha güvenli
kabul edilebilir.
