The sole objective of casting procedure is to provide a metallic duplication of missing tooth structure, with as great accuracy as possible. The ability to produce well fitting castings require strict adherence to certain fundamentals. A study was undertaken to comparatively evaluate the effect on casting accuracy by subjecting the invested wax patterns to burnout after different time intervals. The effect on casting accuracy using metal ring into a pre heated burnout furnace and using split ring was also carried. The readings obtained were tabulated and subjected to statistical analysis.
铸造工艺的唯一目标是尽可能精确地提供缺失牙体结构的金属复制品。生产贴合良好的铸件的能力需要严格遵守某些基本原则。进行了一项研究，通过在不同时间间隔后对包埋的蜡型进行焙烧，比较评估其对铸造精度的影响。还研究了将金属环放入预热的焙烧炉和使用开口环对铸造精度的影响。将获得的读数制成表格并进行统计分析。
