Effect of cement space on retention and marginal fit of implant-supported restorations cemented to prefabricated abutments with retentive features

Key Points

• The aim is to assess how different cement spaces influence the retention and marginal fit of implant-supported restorations.
• Randomized trial with various cement space dimensions
• Used prefabricated abutments with retentive features
• Analyzed retention and marginal fit metrics
• Cement space significantly impacts retention rates, with optimal dimensions yielding higher retention
• Marginal fit measurements varied with cement space, indicating an ideal range for best fit
• Statistical analysis shows p-values indicating strong effects between tested groups
