Abstract

Amaç: Bu in vitro çalışmanın amacı implant
çevresi alanların ölçümünde kullanılan çeşitli
radyodiagnostik metodların hassasiyetlerini
değerlendirmek ve karşılaştırmaktır.
Gereç ve Yöntem: İnsan kadavrasına ait alt çeneye
6 adet dental implant yerleştirildi. İmplant ve
implant çevresi kemik ölçümleri için hem paralel
hem de açıortay tekniği ile elde edilen periapikal
radyografiler, dijital ve konvansiyonel panoramik
radyografiler kullanıldı. Her implantın ölçüm
sonuçları istatistiksel olarak analiz edildi.
Bulgular: Gözlemciler arası güvenilirlik için sınıf
içi korrelasyon değerleri implant çapı için 0.79,
implant uzunluğu için 0.96’dır. 2 gözlemcinin
ölçümleri ve anatomik konumlara ilişkin implant
ebatları arasında istatistiksel olarak anlamlı bir
fark bulunamamıştır. Her gözlemcinin ölçümünün,
paralel teknik kullanılarak yapılan ölçümlerde diğer
tekniklere göre implantların gerçek ebatlarından
anlamlı olarak daha az fark gösterdiği belirlenmiştir
(p < 0.05).

THE COMPARISON OF THE PRECISION OF DIFFERENT DENTAL RADIOGRAPHIC METHODS IN MANDIBULAR PERI-IMPLANTARY MEASUREMENTS: AN IN VITRO STUDY

Abstract

Purpose: The objective of this in vitro study was to investigate and compare the precisions of several radiodiagnostic methods used in dentistry for the measurement of peri-implantary sites.
Materials and Methods: Six dental implants were placed in a human cadaver mandible. Periapical radiographs obtained with the parallel as well as the bisecting angle technique, digital and conventional panoramic radiographs were used for implant and periimplant bone measurements. The measurement results at each implant were statistically analyzed.
Results: The ICC values for the inter-observer reliability were 0.79 for implant diameters and 0.96 for implant lengths. Statistical significance was not detected between the differences of the measurements of the 2 examiners from the original implant dimensions related to anatomic locations. For both of the examiner measurements, significantly less difference from the original implant dimensions was detected in the parallel technique compared to the other techniques (p<0.05).
Conclusion: The present study showed that the most precise peri-implant bone measurements can be obtained from periapical radiographies by using the parallel technique.
