Kısmi Ark Dijital İmplant Ölçülerinde 2 Farklı Ağız İçi Tarayıcının Doğruluğu: Karşılaştırmalı Bir İn Vitro Çalışma

Abstract

Amaç: Bu çalışmanın amacı, 2 farklı ağız içi tarayıcı ile elde edilen kısmi ark dijital implant ölçülerinin doğruluğunu değerlendirmekti. Gereç ve Yöntemler: Cerec Omnicam ve Trios 3 ağız içi tarayıcıların doğruluğu gerçeklik sapması ve hassasiyet sapması ile değerlendirildi. İki implant analoğu bulunan bir alçı model ağız içi tarayıcılar ile taranarak test taramaları elde edildi (n=10). Aynı model bir masaüstü tarayıcı ile taranarak referans tarama verisi elde edildi. Test taramalarındaki tarama gövdeleri ile referans tarama gövdeleri bir tersine mühendislik yazılımında çakıştırıldı ve üç boyutlu sapmalar hesaplanarak gerçeklik sapması hesaplandı. Test taramalarının birbiri ile çakıştırılması ile elde edilen sapmalar ise hassasiyet sapması olarak kaydedildi. Verilerin normalliği Shapiro-Wilk testi kullanılarak değerlendirildi. Tarayıcılar arasındaki istatistiksel olarak anlamlı farklar Bağımsız örnekler t testi ile incelendi. Bulgular: Cerec Omnicam, Trios 3’ e göre istatistiksel olarak daha düşük gerçeklik ve hassasiyet sapması gösterdi (p<0,001). Cerec Omnicam ile gerçekleştirilen taramaların ortalama gerçeklik sapması 15,75 ± 2,93 m iken Trios 3 ile gerçekleştirilen taramaların ortalama gerçeklik sapması 25,78 ± 2,22 m olarak elde edildi. Cerec Omnicam ile gerçekleştirilen taramaların ortalama hassasiyet sapması 5,05 ± 1,61 m iken Trios 3 ile gerçekleştirilen taramaların ortalama hassasiyet sapması 7,73 ± 1,94 m olarak elde edildi. Sonuç: Kısmi ark dijital implant ölçülerinin doğruluğu tarayıcı tipine göre değişiklik gösterdi. Bununla birlikte her iki tarayıcının gerçeklik ve hassasiyet sapması, klinik olarak kabul edilebilir sınırın altında bulundu. Anahtar Kelimeler: Ağız içi tarayıcı, dijital implant ölçüsü, tarayıcı doğruluğu

Accuracy of 2 Different Intraoral Scanners for Partial Arch Digital Implant Impressions: A Comparative In Vitro Study

Abstract

Objective: The aim of this study was to assess the accuracy of partial arch digital implant impressions obtained with 2 different intraoral scanners. Methods: The accuracy of Cerec Omnicam and Trios 3 intraoral scanners was evaluated based on trueness and precision deviations. A plaster model with 2 implant analogs was scanned using intraoral scanners to obtain test scans (n=10). A reference scan was obtained by scanning the same model with a desktop scanner. The scan bodies of the test scans were superimposed with the reference scan bodies using reverse engineering software, and three-dimensional deviations were calculated to determine the trueness. The deviations obtained from the superimposition of test scans with each other were recorded as precision deviations. The normality of the data was assessed using the Shapiro-Wilk test. Statistically significant differences between the scanners were analyzed using the Independent samples t-test. Results: Cerec Omnicam showed statistically significantly lower trueness and precision deviations compared to Trios 3 (p<0.001). The mean trueness deviation of Cerec Omnicam was 15.75 ± 2.93 µm, whereas the mean trueness deviation of Trios 3 was 25.78 ± 2.22 µm. The mean precision deviation of Cerec Omnicam was 5.05 ± 1.61 µm, while the mean precision deviation of Trios 3 was 7.73 ± 1.94 µm. Conclusion: The accuracy of partial-arch digital implant impressions varied depending on the scanner type. However, both scanners exhibited trueness and precision deviations that were below the clinically acceptable threshold. Keywords: Intraoral scanner, digital implant impression, scanner accuracy
