Comparative evaluation of marginal fit in conventional versus high-speed-sintered zirconia crowns: an in vitro study

Key Points

• Clinically acceptable marginal fit observed in both zirconia crown types, though conventional sintering led to better outcomes.
• Conventional zirconia crowns demonstrated significantly superior marginal fit compared to high-speed sintered variants.
• In vitro study evaluated the differences in marginal fit across sintering programs for zirconia crowns.
• Findings suggest that conventional sintering may provide improved clinical reliability in crown fit.
