Fixed bonded prosthodontics: a 10-year follow-up report. Part I: Analytical overview
Summary
Resin-bonded prostheses offer a viable solution for replacing one or two missing teeth, demonstrating an 83% survival rate over 10 years. Proper tooth preparation is crucial for splints, especially in patients with periodontal disease.
Area of Science:
- Dental biomaterials
- Adhesive dentistry
- Prosthodontics
Background:
- Advancements in biomaterials and adhesion have enabled less invasive dental procedures.
- Analysis of resin-bonded prosthesis failures suggests the need for micropreparation of abutment teeth.
Purpose of the Study:
- To evaluate the long-term success rate of resin-bonded prostheses and splints.
- To assess the viability of resin-bonded prostheses for single or double tooth replacement.
Main Methods:
- A 10-year longitudinal study (1984-1993) was conducted.
- Survival rates were analyzed using the Kaplan-Meier test.
- The study examined 145 resin-bonded prostheses and splints.
Main Results:
- An overall survival rate of 83% was achieved for resin-bonded prostheses.
- 11 out of 145 prostheses failed during the study period.
- Tooth preparation was confirmed as critical for splint success in periodontally compromised patients.
Conclusions:
- Resin-bonded prostheses are a successful treatment option for patients with one or two missing teeth.
- Micropreparation of abutment teeth is recommended for improved outcomes.
- Effective preparation is essential for managing stresses in resin-bonded splints, particularly in cases of tooth mobility due to periodontal disease.
