Summary
Resin-bonded prostheses show promising long-term results, with low caries rates and favorable periodontal health. These restorations may be considered permanent dental solutions.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Clinical Dentistry
Background:
- Resin-bonded prostheses (RBPs) offer a conservative approach to tooth replacement.
- Long-term clinical data on the survival and performance of RBPs are crucial for establishing their efficacy.
Purpose of the Study:
- To evaluate the long-term clinical outcomes of resin-bonded prostheses over a 10-year period.
- To assess factors influencing the success and longevity of RBPs.
Main Methods:
- A retrospective study examining 99 resin-bonded prostheses after 10 years.
- Standardized criteria were used by four clinicians to assess hard tissues, periodontium, and prosthesis integrity.
- Data from 7- and 10-year studies were compared to identify trends.
Main Results:
- Caries on retainer teeth occurred in 3% of cases.
- Retainer teeth exhibited better gingival health and reduced probing depths compared to the general dentition.
- The overall debond rate was 31%, with similar rates for etched metal and perforated retainers.
- 83% of patients expressed satisfaction with the prostheses.
Conclusions:
- Resin-bonded prostheses demonstrate favorable clinical performance and patient satisfaction over a decade.
- RBPs can be considered a durable and valuable permanent restoration option in clinical practice.
