摘要
本文研究了现在临床常用的三种不同组成的内包埋材料对铸造全冠及单内、双内铸道对三单位双端固定桥铸造精度的影响。在三种包埋材料中,以 B 种材料包埋制作的铸造全冠的精度最高,适合性最好,C 种次之,A 种再次之。安插双内铸道的固定桥的精度和造合性较安插单内铸道者好。
Three kinds of inner investment materials routinely used in clinic and their effect oncasting precision have been investigated in full crowns with either single or double spruesand three-unit bridge.As a result,No.B shows the best precision and adaptability,No.Ccomes sccond and No.A wins the third place among these investment materials.In theexperiment of full crowns the precision and adaptability of FPDs with double inner spruesare superior to those with single sprue.
