Secondary Caries Susceptibility In Prosthodontics Correlated To Marginal Gap, Gordana Kovacevska

UBT International Conference

Introduction: Secondary caries of abutment teeth is an unwanted complication during prosthodontics treatment and the main reason for the replacement of FPD restorations. Marginal gap space in fixed restorations is responsible for micro-leakage and cement decomposition with caries appearance due to specific demineralization process by bacteria colonization. The aim of the study was to evaluate caries lesions in correlation to the crown marginal gap.

Material and methods: Marginal gap between the abutment tooth and the crown was measured using a light-body silicone for evaluating of absolute discrepancy with replica technique (RT). Twenty porcelain fused to metal crowns were fabricated on …
