Summary
Zirconia-based all-ceramic fixed partial dentures (FPDs) anchored by inlays showed acceptable function and aesthetics but had high complication rates. Improved resin cement adhesion is needed for wider clinical recommendation of these inlay-retained FPDs.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Biomaterials
Background:
- All-ceramic restorations offer aesthetic advantages.
- Zirconia-based materials provide high strength.
- Inlay-retained fixed partial dentures (FPDs) present a minimally invasive treatment option.
Purpose of the Study:
- To evaluate the clinical performance of zirconia-based all-ceramic FPDs.
- To assess complications, plaque accumulation, and aesthetics of inlay-retained FPDs.
- To determine the influence of resin cements on FPD outcomes.
Main Methods:
- Thirty zirconia-based, press ceramic-veneered FPDs replacing a single molar were fabricated.
- FPDs were adhesively luted using one of two resin cements.
- Clinical performance, complications, plaque, and aesthetics were documented over 12 months.
Main Results:
- High complication rates observed: 4 veneer delaminations, 6 decementations, and 3 framework fractures.
- No statistically significant effect of cement type, location, or retainer design on complications.
- Acceptable aesthetic and functional performance with no significant increase in plaque accumulation.
Conclusions:
- Improved adhesion between resin cement and inlay retainers is crucial for the general recommendation of all-ceramic inlay-retained FPDs.
- Current luting cements did not significantly impact complication rates in this study.
- Further research into cement-restoration interfaces is warranted.
