Abstract
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 of ten 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 (∆X, ∆Y and ∆Z-axis), angular (∆ANGLE) and three-dimensional (Euclidean distance, ∆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 ∆X, ∆Z and ∆EUC compared to PEEK scanbodies (p<0.05). Conclusion: PEEK scanbodies provided more accurate and consistent digital scans than titanium.
