Treatment Time Comparing Digital & Conventional Workflows

Not Applicable

Completed

• Conditions: Dental Implant
• Interventions: Procedure: Treatment of implant single crown

• Registration Number: NCT05165563
• Lead Sponsor: Mahidol University

Brief Summary

This randomized controlled trial (RCT) analyzed monolithic single-unit implant restorations out of lithium disilicate (LS2) or polymer-infiltrated ceramic networks (PICN) in a chairside digital workflow (Test) and a conventional protocol (Control). The primary outcome was to investigate the treatment time of the overall operation. The null hypothesis of this RCT was that both workflows had comparable results with respect to the defined outcomes.
