Alt Çene İmplant Çevresi Ölçümlerinde Farklı Dental Radyografik Yöntemlerin Hassasiyetlerinin Karşılaştırılması: In Vitro Çalışma

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

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.
