Abstract

The surgical evaluation of the apicoectomy with various types of alveolar bone resorption was conducted in current study. The apicoectomy is the common and important treatment in endodontics. Finite element analysis was used for evaluation. The 3D solid model of the maxillary central incisor was reconstructed using CT images of a mature Asian female. Loading and boundary conditions were simulated in the normal mastication of maxillary central incisor. For evaluation of apicoectomy, lingual, labial and entire alveolar bone resorption models were developed. In the results, lingual alveolar bone resorption did not significantly influence stress distribution pattern of root dentin and labial alveolar bone had an important role for supporting structural stability in tooth system.

본 논문에서는 치조골의 흡수 유형에 따른 치근단 절제술의 수술적 평가를 수행하였다. 유한요소해석이 사용되었으며 CT 이미지를 통하여 동양 성인 여성의 상악 중절치의 3D 모델을 사용하였다. 연구에는 상악중절치의 정상저작하중조건이 적용되었다. 치조골 흡수 유형에 따른 치근 절제술의 평가를 위해 정상모델과 함께 치조골의 전체적 흡수 모델, 순측 흡수 모델 및 설측 흡수 모델을 비교하였다. 이에 따라 설측 치조골 흡수의 영향은 순측 치조골의 흡수에 비해 치아의 유지 안정성에 미치는 영향이 작음을 확인하고, 설측 치조골 흡수로 인해 치근이 노출된 환자를 대상으로 한 치근 절제술의 위험 가능성을 제시하였다.
