Abstract

In advanced stages of periodontal disease, a lot of the periodontal tissue support are usually lost. The tissue destruction around some teeth is progressed to a level which requires either spontaneous exfoliation or extraction of several teeth due to their excessive mobility. In such cases, a comprehensive treatment plan encompassing the adequate periodontal and maintenance therapy, as well as perio-prosthetic treatment involving occlusal equilibration, is needed in order to restore health, function, and esthetics. Cross-arch fixed partial dentures(CAFPDs), one of the perio-prosthetic treatments, are used to stabilize the teeth with severely reduced periodontal tissue support. Unfortunately, however, a little is known about the occlusal scheme and biomechanical concept of CAFPDs. This paper will demonstrate summaries of the trauma from occlusion(TFO), Ante's law revisited, the treatment principles, the role of occlusion, and the long-term consequences for CAFPDs, and the possibility of CAFPDs through a case presentation.

치주질환이 중증도 이상으로 진행되면 대개 많은 량의 치주조직지지가 상실된다. 일부 치아 주변으로 발생되는 이러한 조직 파괴는 그들의 심한 동요 때문에 일부 치아들은 스스로 탈락되거나 발치가 요구되는 단계까지 진행된다. 이러한 경우에 적절한 치주치료와 유지 그리고 교합평형을 고려한 치주-보철 치료를 포함하는 포괄적 치료계획이 그들의 건강, 기능, 심미 등의 수복을 위해 필요하게 되고, 이러한 치주-보철치료 중의 하나인 크로스-아치 고정성국소의치(cross-arch fixed partial dentures, CAFPDs)가 심하게 감소된 치주조직지지를 갖는 치아들의 안정을 위해 사용될 수 있다. 그러나 불행하게 이러한 보철물의 디자인에 따른 생역학적 개념과 교합양식에 대해 아직 많이 알려져 있지 않은 상태이다. 본 논고에서는 교합성외상 그리고 CAFPDs를 통해서 본 Ante's law의 재조명, 치료 원칙, 교합부여, 장기적 예후 등에 대한 정리를 보여줄 것이며 증례를 통해 그 가능성을 제시해 보고자 한다.
