Intra-oral restorative materials wear: rethinking the current approaches: how to measure wear.

摘要: Abstract Objective To determine what wear parameter(s) have clinical relevance and factors are important for accurate measurement of these parameters in vivo vitro. Method Describe biomechanical affecting mastication the mechanics wear. Investigate how they impact teeth restorative materials. Based on this information, define advantages disadvantages using volume, depth, area to quantify direct indirect methods measuring point out each. Results The preferred parameter quantifying is volume. It independent occlusal a measure work done. If material environmental remain constant, volume loss linear with time. Depth limited value because their dependence factors; plus, not When interest opposing must be considered; especially if enamel. Wear best measured by comparing sequential 3D images. Measuring systems should calibrated error reported sigma values rather means standard deviations. quality alignment images included analysis. Cost availability imaging has severely use studies. Significance an consequence interactions. controlled, could lead poor masticatory function concomitant reduction life possible deterioration systemic health.
