Key Points

This research aims to evaluate the precision of titanium and PEEK scan bodies following sterilization and thermal disinfection.
Conducted an in vitro study comparing titanium and PEEK scan bodies
Assessed scan precision post-sterilization and thermal disinfection
Evaluated mechanical stability and reusability of both materials
PEEK scan bodies showed higher overall precision but limited mechanical stability
Titanium scan bodies, while slightly less precise, supported multiple reuses without significant loss of quality
Recommendations for further clinical studies on prolonged reprocessing of these materials

Abstract

PEEK scan bodies demonstrate higher precision but may be limited by lower mechanical stability and their single-use concept. Titanium scan bodies, although slightly less precise, have proven to be mechanically robust and suitable for multiple reuses after the conducted reprocessing. Further clinical studies with extended re-processing cycles are required to confirm these findings.
