Summary
CerAdapt ceramic abutments demonstrate safe long-term clinical function and high success rates when used with Brånemark implants for fixed partial dentures. These ceramic abutments offer comparable results to titanium, ensuring both function and esthetics.
Area of Science:
- Dental Implantology
- Biomaterials Science
- Prosthodontics
Background:
- Titanium abutments are standard for dental implants.
- Ceramic abutments offer potential esthetic and biocompatibility advantages.
- Long-term clinical data on ceramic abutments for fixed partial dentures (FPDs) is crucial.
Purpose of the Study:
- To evaluate the 5-year clinical function of CerAdapt alumina ceramic abutments versus titanium abutments.
- To compare the performance of ceramic and titanium abutments supporting short-span fixed partial dentures (FPDs) on Brånemark implants.
Main Methods:
- A prospective, randomized, controlled 5-year multicenter study.
- 103 Brånemark implants received either 53 ceramic or 50 titanium abutments supporting 36 FPDs.
- Clinical function, survival rates, marginal bone loss, and soft tissue parameters were assessed over 5 years.
Main Results:
- Cumulative success rate for FPDs was 97.2% (94.7% ceramic, 100% titanium).
- Abutment survival rates were 98.1% for ceramic and 100% for titanium.
- No significant differences in marginal bone loss or soft tissue health (bleeding, plaque) were observed between abutment types.
Conclusions:
- CerAdapt alumina ceramic abutments provide safe and effective long-term clinical function for Brånemark implants supporting short-span FPDs.
- Both ceramic and titanium abutments demonstrated high success and survival rates.
- The study supports the use of ceramic abutments for achieving favorable functional and esthetic outcomes.
