초록

지르코니아는 다양한 공정과정을 거쳐서 제작되며, 각각의 요소는 최종 보철물의 물성에 영향을 줄 수 있다. 특히 밀링과정과 소결과정이 모두 지르코니아 보철물의 최종 완성도(integrity)에 영향을 미칠 수 있다. 밀링머신은 대부분 초정밀 5축 가공방식을 채택하고 있으며 어떤 방식을 사용하고 밀링기구를 어떻게 관리하는가에 따라서도 결과가 달라진다. 밀링블록은 절삭의 효율성과 심미재현성에 따라 선택하는데 물성의 변화를 야기할 수 있음은 주의해야 한다. 소결방식은입자성장과 광학적 특성에 영향을 미칠 수 있는데 속도를 조절하는 최근의 방식에 대해서는 추가적인 연구가 동반되어야 정확한 평가가 이루어질 수 있다. 소결온도 뿐 아니라 온도 유지시간도 최종결과물에 영향을 줄 수 있다.

Abstract

Zirconia is fabricated through various processes. Each element in fabricating process can affect the physical properties of thedefinitive prosthesis. In particular, both the milling process and the sintering process can affect the final integrity of the zirconiaprosthesis. Most of the milling machines adopt the ultra-precision 5-axis machining method, and the results vary depending onwhich milling method was used and how the milling equipment was managed. Milling blocks are selected according to cuttingefficiency and aesthetic reproducibility. The sintering method can affect the grain growth and optical properties, and an accurateevaluation can be made only with additional research on the recent speed sintering procedure. Not only the sintering temperaturebut also the temperature holding time can affect the quality of definitive prosthesis.
