Why it matters for dental
3D-printed resin crowns are increasingly adopted for same-day restorations; this study shows that post-print cleaning solvents directly affect long-term wear resistance and fracture toughness, giving owners of chairside printing systems a controllable variable that can reduce remake risk and lab fees.
Key points
- Peer-reviewed RCT in JPD (Oct 2026) tested three common post-print cleaning solutions on printed resin crowns subjected to thermomechanical aging simulating 1-year clinical service.
- Crowns cleaned with the tested solvents showed statistically different occlusal wear depths and fracture loads after aging, highlighting solvent choice as a material performance driver.
- Results apply to labs and in-office workflows using resin-based crown resins; practices that print in-house can adjust SOPs without capital expenditure.
- Authors: Gökberk Koçer et al.; full methods and quantitative wear/fracture data available in JPD Vol. 136, Issue 4.
