Summary
This systematic review found metal-ceramic implant-supported prostheses have fewer mechanical complications than zirconia-ceramic ones. However, both materials show similar survival rates for fixed dental prostheses.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Biomaterials Engineering
Background:
- Implant-supported prostheses are crucial for restoring partial edentulism.
- Material choice significantly influences prosthesis esthetics and peri-implant health.
- Zirconia-ceramic and metal-ceramic are common materials for multiunit fixed dental prostheses (FDPs).
Purpose of the Study:
- To systematically review and compare the survival rates and mechanical complications of zirconia-ceramic versus metal-ceramic implant-supported multiunit FDPs.
- To provide evidence-based insights for clinicians selecting restorative materials.
Main Methods:
- Systematic literature search of MEDLINE (PubMed), Scopus, and Cochrane databases up to December 2022.
- Inclusion of six studies (four RCTs, two retrospective studies) with risk-of-bias assessment.
- Meta-analysis of mechanical complications and prosthesis survival rates.
Main Results:
- Metal-ceramic restorations showed significantly fewer mechanical complications (RR = 1.64, P = 0.001).
- No significant difference was observed in prosthesis survival rates between metal-ceramic and zirconia-ceramic FDPs (P = 0.63).
- Low heterogeneity was noted for survival rate analysis (I² = 0%).
Conclusions:
- Metal-ceramic implant-supported FDPs demonstrate superior mechanical complication resistance compared to zirconia-ceramic.
- Both zirconia-ceramic and metal-ceramic FDPs are viable options for long-term implant restorations.
- Further research may explore long-term esthetic outcomes and patient-reported satisfaction.
