Especially, we can say that the inclined forward positions of the mandible may affect the vertical measurements made according to the mandible regions.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective: The aim of this study is to compare the linear measurements made on the images obtained from three different inclinations using cone-beam computed tomography (CBCT) from the dry bone mandibles with the anatomical measurements made directly on the dry bone mandibles, to evaluate and discuss the compatibility between these measurements.
📊
Key Findings & Data:Material and Methods: The study included 20 dry bone mandibles and a total of 60 CBCT images were obtained for each jaw with the mandibular base parallel to the floor (parallel position) as well as +45º (up position) and -45º angle (down position).

Abstract

Objective: The aim of this study is to compare the linear measurements made on the images obtained from three different inclinations using cone-beam computed tomography (CBCT) from the dry bone mandibles with the anatomical measurements made directly on the dry bone mandibles, to evaluate and discuss the compatibility between these measurements. Material and Methods: The study included 20 dry bone mandibles and a total of 60 CBCT images were obtained for each jaw with the mandibular base parallel to the floor (parallel position) as well as +45º (up position) and -45º angle (down position). Linear measurements were made on the images obtained from with different inclinations. Results: Statistically significant differences were found between the three positions in CBCT measurements of the distance between the laterals of the right and left condyles, the distance between the right and left coronoid processes, the distance between the left coronoid point and the left mental foramen, and the distances between the left coronoid point and the right mental foramen. Conclusion: The reliability of measurements made on CBCT images using prominent anatomical landmarks does not depend on the experience of the operator, the measurements made on CBCT tend to be slightly less predictive than the anatomical measurements, all the measurements obtained in the down position in the CBCT scan are higher than the measurements in the up and parallel positions. Especially, we can say that the inclined forward positions of the mandible may affect the vertical measurements made according to the mandible regions.

Özet

Amaç: Bu çalışmanın amacı, kuru kemik mandibulalarından konik ışınlı bilgisayarlı tomografi (CBCT) kullanılarak üç farklı eğimden elde edilen görüntüler üzerinde yapılan doğrusal ölçümleri, doğrudan kuru kemik mandibulaları üzerinde yapılan anatomik ölçümlerle karşılaştırmak, bu ölçümler arasındaki uyumluluğu değerlendirmek ve tartışmaktır. Gereç ve Yöntemler: Çalışmaya 20 kuru kemik mandibula dahil edildi ve her çene için mandibular tabanı zemine paralel (paralel pozisyon) ve +45º (yukarı pozisyon) ve -45º (aşağı pozisyon) açıyla olmak üzere toplam 60 CBCT görüntüsü elde edildi. Farklı eğimlerden elde edilen görüntüler üzerinde doğrusal ölçümler yapıldı. Bulgular: KIBT ölçümlerinde, sağ ve sol kondil lateralleri arasındaki mesafe, sağ ve sol koronoid çıkıntılar arasındaki mesafe, sol koronoid nokta ile sol mental foramen arasındaki mesafe ve sol koronoid nokta ile sağ mental foramen arasındaki mesafe olmak üzere üç pozisyon arasında istatistiksel olarak anlamlı farklar bulunmuştur. Sonuç: Belirgin anatomik işaret noktaları kullanılarak KIBT görüntüleri üzerinde yapılan ölçümlerin güvenilirliği, operatörün deneyimine bağlı değildir, KIBT'de yapılan ölçümler anatomik ölçümlere göre biraz daha az öngörücü olma eğilimindedir, KIBT taramasında aşağı pozisyonda elde edilen tüm ölçümler, yukarı ve paralel pozisyonlardaki ölçümlerden daha yüksektir.
