Titanium versus ceramic implants for overdentures: a meta-analysis of prospective studies
General Dentistry
|June 29, 2021
Summary
Titanium implants show better clinical outcomes for overdenture support compared to ceramic implants, with lower failure rates and less marginal bone loss (MBL). This finding is based on a meta-analysis of available clinical studies.
Area of Science:
- Dental Implantology
- Biomaterials Science
- Prosthodontics
Background:
- Overdentures offer a stable prosthetic solution for edentulous patients.
- Both titanium and ceramic implants are utilized for overdenture support.
- Comparative data on their long-term clinical performance is crucial.
Purpose of the Study:
- To compare titanium and ceramic implants for overdentures.
- Evaluate failure rates, surface treatments, and marginal bone loss (MBL).
- Synthesize existing clinical evidence through meta-analysis.
Main Methods:
- Systematic literature search of PubMed, Scopus, and Cochrane databases up to October 2019.
- Inclusion of clinical studies comparing titanium and ceramic implants for overdentures.
- Meta-analysis using Mantel-Haenszel and inverse variance methods with a fixed-effects model.
Main Results:
- Two studies with 38 patients (mean age 62) and 1-year follow-up were included.
- Titanium implants: 112 placed, 71.1% success rate, 0.15 mm MBL.
- Ceramic implants: 146 placed, 65.9% success rate, 0.33 mm MBL, higher failure rate.
Conclusions:
- Titanium implants demonstrated superior clinical results for overdenture support.
- Lower failure rates and reduced marginal bone loss favor titanium implants.
- Further research may explore long-term outcomes and specific surface treatments.
