Anterior maksiller bölgedeki bukkal konkavitelerin analizi: Retrospektif konik ışınlı bilgisayarlı tomografi çalışması

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 istatistiksel olarak anlamlı fark bulunamamıştır. Sonuç: 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.

Analysis of the buccal concavity of the anterior maxilla: Retrospective cone-beam computed tomography study

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. Conclusion: Within the limmitations of this study it can be concluded that lateral incisor teeth, rather than the canine, may exhibit high complication risk and alveolar bone augmentation necessity.
