Summary

This randomized controlled clinical trial evaluates the clinical performance of 3D-printed resin restorations compared with milled monolithic zirconia in implant-supported single crowns and short-span fixed partial dentures (FPDs). A total of patients requiring one or two implant-supported restorations in the mandibular anterior region were randomly allocated to receive either 3D-printed permanent resin restorations (CROWNTEC) or conventionally milled zirconia prostheses.

All restorations were fabricated using a standardized digital workflow and assessed over a 12-month follow-up period. The primary outcome was restoration survival rate, while secondary outcomes included technical complications, peri-implant biological parameters, marginal bone level changes, and patient-reported satisfaction.

This study aims to provide clinical evidence regarding the viability of 3D-printed definitive resin materials as an alternative to zirconia in implant prosthodontics.

Interventions

DEVICE

3D-Printed Resin Restoration (CROWNTEC)

Implant-supported single crowns or short-span fixed partial dentures fabricated using 3D-printed permanent resin (CROWNTEC). Restorations are produced using a standardized digital workflow, including intraoral scanning, CAD design, 3D printing at 50 µm layer thickness, post-processing (isopropyl alcohol cleaning, post-curing), finishing, and polishing. Restorations are delivered as screw- or cement-retained prostheses. In addition, Other participants will receive implant-supported single crowns or short-span fixed partial dentures fabricated from monolithic zirconia using CAD-CAM milling. Restorations undergo sintering, finishing, and polishing, and are delive
