Brief 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.
Eligibility Criteria
Inclusion Criteria: * Participants must meet all of the following: * 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. * Require either: * A single implant-supported crown, or * A short-span (maximum 3-unit) implant-supported fixed partial denture (FPD) supported by two implants in the mandibular anterior region. Exclusion Criteria: * Participants are excluded if they have any of the following: * 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.
