Özet

Objective: The study aimed to evaluate the effects of multiple sterilization cycles and repeated clinical use on the stability of monoblock titanium and PEEK scanbodies. Materials and Methods: Ten monoblock titanium and PEEK scanbodies were paired up, thus forming a total often study groups. Each pair was scanned using an intraoral scanner to record a reference scan. Study groups underwent 30 cycles of tightening, loosening and sterilization, respectively. Scanning was performed after every five cycles, resulting in six study scans per group. Linear (triangle X, triangle Y and triangle Z-axis), angular (triangle AN-GLE) and three-dimensional (Euclidean distance, triangle EUC) deviations were calculated and compared using two-way ANOVA test. Results: The number of repeated cycles was insignificant on scanbody deviations for both of the scanbody materials (p>0.05). The scanbody material had a significant impact, with titanium scanbodies demonstrating significantly higher deviations in triangle X, triangle Z and triangle EUC compared to PEEK scanbodies (p<0.05). Conclusion: PEEK scanbodies provided more accurate and consistent digital scans than titanium.
