This article is to review various methods used to investigate internal and marginal adaptation of fixed dental prostheses, and to summarize a merit, worth, and limitation of each method, using some results of previous studies. The methods of measuring internal and marginal gap are divided into two c...

변연적합도가 좋지 않은 경우 어떤 부정적 영향을 주는가? | 2 내면적합도가 확인된 후에는 보철물과 지대치 경계 부위의 연속성을 확인하여 보철물의 변연 부위가 임상적으로 적합한지 평가해야 한다. 변연적합도가 좋지 않은 경우 보철물 내면의 시멘트 용해를 촉진시켜 치아와 치주조직에 부정적인 영향을 주게 되는데, 예를 들면 보철물 주변으로 치태가 축적되고 치은 염증을 유발할 수 있으며, 나아가서는 지대치에 2차 우식이나 치수염을 일으키게 되어 보철물이 실패하는 주된 원인이 된다.3-6 | |
보철물을 시적할 때 내면적합도가 중요한 이유는 무엇인가? | 인접면이나 교합면과 같은 외형적인 요소들은 보철물이 제작된 후 어느 정도 조정이 가능하지만, 내면과 변연의 적합도는 보철물 제작 과정에서 이미 결정되는 만큼 그 보철물의 예후를 결정하는 가장 중요한 요소라고 할 수 있다. 보철물의 적합도는 내면적합도부터 평가하는데, 내면에 먼저 닿는 부분이 존재하는 경우에 보철물이 완전히 들어가지 않아 변연부를 정상적으로 평가할 수 없기 때문이다. 따라서 기공 과정에서 내면적합도 향상을 위한 적절하고 균일한 시멘트 공간에 대한 고려가 필수적이며, 너무 과도한 내면공간은 보철물의 파절, 탈락 등을 야기 할 수 있고,1 너무 작은 내면공간은 보철물의 장착을 불완전하게 할 수 있음을 반드시 숙지해야 한다. | |
보철물 시적에 있어서 내면 및 변연적합도가 외형적인 요소들에 비해서 더 중요한 요소라고 판단되는 이유는 무엇인가? | 치과의사가 보철물을 시적할 때에는 일반적으로 인접면 검사, 내면 및 변연적합도 검사, 교합검사를 반드시 해야 한다. 인접면이나 교합면과 같은 외형적인 요소들은 보철물이 제작된 후 어느 정도 조정이 가능하지만, 내면과 변연의 적합도는 보철물 제작 과정에서 이미 결정되는 만큼 그 보철물의 예후를 결정하는 가장 중요한 요소라고 할 수 있다. 보철물의 적합도는 내면적합도부터 평가하는데, 내면에 먼저 닿는 부분이 존재하는 경우에 보철물이 완전히 들어가지 않아 변연부를 정상적으로 평가할 수 없기 때문이다. |
