The present investigation has shown that the surface of gold alloys cast in both a new and probably improved investment and in two commercial gypsum-bonded investments fulfills all conventional clinical requirements as regards retention and precision of the cemented restorations and easy polishability. With a view to retention the sometimes slightly rougher surfaces of castings in the new investment are advantageous.
目前的研究表明,在一种新型且可能有所改进的包埋材料以及两种市售石膏粘结包埋材料中铸造的金合金表面,在粘结修复体的固位、精度和易于抛光性方面均满足所有传统临床要求。就固位而言,新型包埋材料中铸造的铸件表面有时略粗糙一些是有利的。
