铸造性差或不一致通常需要昂贵的实验室重制铸造修复体。本研究研究了燃尽温度和合金包埋兼容性对所选合金铸造性的影响。在 A 部分中，对九种合金投资组合进行了比较。在 B 部分中，对四种烧毁温度下的两种合金包埋组合进行了评估。熔模、合金和/或烧尽温度的差异显着影响铸造性。与天然气/氧气相比，使用更热的丙烷/氧气燃料源可以改善铸造投资较差的铸造性能。
Poor or inconsistent castability often necessitates costly laboratory remakes of cast restorations. This study investigated the effects of burnout temperature and alloy investment compatibility on the castability of selected alloys. In part A nine alloy investment combinations were compared. In part B two alloy-investment combinations at four burnout temperatures were evaluated. Differences in investment, alloy, and/or burnout temperature significantly affected castability. Castability with a poorer casting investment improved with a hotter propane/oxygen fuel source compared with natural (city) gas/oxygen.
