Marginal and internal adaptation of esthetic crowns for primary molars: an in-vitro study

Key Points

• Marginal adaptation of esthetic crowns significantly influences longevity in primary molars, ensuring better clinical outcomes.
• Measurements showed a critical defect size of 0.5 mm in marginal adaptation, with implications for longevity of dental restorations.
• In-vitro study setup analyzed adaptation characteristics using precision tools for measurement across various crowns.
• Findings highlight potential for improving esthetic crown design, though in-vitro results need validation in clinical settings.
