About this trial
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.
Eligibility criteria
Qualifiers
Age ≥18 years.
Have one or two osseointegrated dental implants requiring prosthetic restoration.
Demonstrate stable peri-implant tissues with no signs of inflammation or implant mobility.
Maintain good oral hygiene and controlled periodontal status.
Disqualifiers
Severe parafunctional habits (e.g., bruxism).
Uncontrolled systemic diseases affecting bone metabolism or healing.
Peri-implantitis or compromised implant stability.
Requirement for cantilever prostheses or long-span restorations, or FPDs in areas other than the mandibular anterior region.
