Summary
All-ceramic inlay-retained fixed dental prostheses (CIR-FDPs) are a viable option for replacing posterior teeth. Zirconia-based options show promise, but improvements in bonding and connector strength are needed for optimal clinical success.
Area of Science:
- Dental Prosthodontics
- Biomaterials Science
- Evidence-Based Dentistry
Background:
- All-ceramic inlay-retained fixed dental prostheses (CIR-FDPs) are increasingly used for posterior tooth replacement.
- Evaluating the current evidence on their efficacy and limitations is crucial for clinical decision-making.
Purpose of the Study:
- To systematically review and evaluate the scientific evidence on all-ceramic inlay-retained fixed dental prostheses (CIR-FDPs) for replacing posterior teeth.
Main Methods:
- A comprehensive literature search was conducted across multiple electronic databases (MEDLINE/PubMed, EMBASE, Cochrane, Compludoc).
- Two independent reviewers screened titles and abstracts, performed full-text analysis, assessed study quality, and extracted data.
- Study quality was evaluated using established tools including the 'QDP', 'Guidelines for managing overviews', Cochrane risk of bias tool, and GRADE scale.
Main Results:
- Twenty-three studies met the inclusion criteria from an initial 4942 articles.
- Zirconia-based CIR-FDPs show potential for single posterior tooth replacement, though prosthesis/tooth bonding and connector/retainer integrity require enhancement.
- Monolithic zirconia fabrication may mitigate chipping issues, while lateral wing additions to inlay preparations appear promising. Caries and endodontic complications are common biological issues.
Conclusions:
- Three-unit CIR-FDPs represent a viable treatment for missing posterior teeth.
- Careful case selection, precise abutment preparation, and appropriate luting techniques are paramount for successful clinical outcomes.
