Nettet1. mar. 2024 · There are claims that there is an increase in marginal adaptation in the line angles and point angles of cavity preparations 5 since these materials are lower in viscosity compared to conventional composites and, therefore, there is a reduction for the potential of marginal failure from microleakage. Nettet15. des. 2024 · The line angles can be subdivided in external and internal. The internal line angles are line angles whose apex points into the tooth. They can be divided into two sets. The first set includes the ones created by the junction of two external walls ( Fig. 5.7 red line – 1 st S).
