초록

임플란트는 자각증상을 느끼기 어렵고, 완충역이 없으므로 응력 분포를 고려하지 않는 경우 기계적 실패를 야기할 수 있다. 다수의 상악 전치부 임플란트 수복의 경우 하악의 기능 운동 시 유도를 담당함으로써, 임플란트에 가해지는 측방력의 분산에 중요한 역할을 하므로, 적절한 가이드의 설정이 중요하다. T-scan system을 이용하는 방법은 교합지나 shimstock을 사용하는 기존의 정성적인 방법에 비해, 시간에 따른 교합의 변화와 기능 운동시 접촉되는 치아의 기여정도 및 육안으로 관찰하기 어려운 후방 구치나 반대편 치아의 접촉을 파악하는 등 동적인 교합평가에 유리하다. 본 논문에서는 다수의 상악 임플란트 보철물에 조화로운 전방유도를 부여하기 위하여 T-scan 분석을 활용하는 방법에 관하여 증례를 통해 살펴보고자 한다.

In implant restorations, it is difficult for the patient to percept any symptoms. In addition, they are absent of shock absorbers, which can lead to mechanical failure if stress distribution is not considered. Since maxillary anterior multiple-implant restorations play a significant role in guiding the functional movement of the mandible by distributing lateral force, it is crucial to form appropriate occlusion. The use of the T-scan system is more advantageous in assessing 'dynamic occlusion', such as the change of occlusion over time, the amount of tooth contact during functional movement, and assessing the occlusion in the less-visible posterior teeth. The case is reported as it has satisfactory results in harmonious anterior guidance of a maxillary anterior multiple-implant restoration using T-scan analysis.
