Abstract

The purpose of this study was to investigate the effects of composite resin restorations on the stress distribution of notch shaped noncarious cervical lesion using three-dimensional (3D) finite element analysis (FEA). Extracted maxillary second premolar was scanned serially with Micro-CT (SkyScan1072 ; SkyScan, Aartselaar, Belgium). The 3D images were processed by 3D-DOCTOR (Able Software Co., Lexington, MA, USA). ANSYS (Swanson Analysis Systems, Inc., Houston, USA) was used to mesh and analyze 3D FE model. Notch shaped cavity was filled with hybrid or flowable resin and each restoration was simulated with adhesive layer thickness ($40{\mu}m$) A static load of 500 N was applied on a point load condition at buccal cusp (loading A) and palatal cusp (loading B). The principal stresses in the lesion apex (internal line angle of cavity) and middle vertical wall were analyzed using ANSYS. The results were as follows 1. Under loading A, compressive stress is created in the unrestored and restored cavity. Under loading B, tensile stress is created. And the peak stress concentration is seen at near mesial corner of the cavity under each load condition. 2. Compared to the unrestored cavity, the principal stresses at the cemeto-enamel junction (CEJ) and internal line angle of the cavity were more reduced in the restored cavity on both load con ditions. 3. In teeth restored with hybrid composite, the principal stresses at the CEJ and internal line angle of the cavity were more reduced than flowable resin.

이 연구의 목적은 쐐기형 비우식성 5등급와동을 복합레진으로 수복하기 전, 후에 과도한 교합력에 의한 응력분포 변화를 비교 연구하기 위함이었다. 발치된 상악 제 2소구치를 이용하여 쐐기형 비우식성 치경부병소를 가진 3차원 유한요소모형을 제작한 후 탄성계수가 서로 다른 혼합형 복합레진과 흐름성 복합레진으로 각각 충전하고 이때의 상아질 접착제의 두께는 $40{\mu}m$로 하였다. 협측교두와 설측교두에 500 N의 하중을 각각 가한 후 ANSYS 프로그램을 이용하여 주응력분석법으로 병소의 심부와 와동 수직병의 응력분포를 비교하여 다음과 같은 결과를 얻?B다. 1. 협측교두에 하중이 가해지면 병소에 압축응력이 나타나고, 설측교두에 가해지면 인장응력이 나타난다. 두 가지 하중에서 모두 병소의 근심 끝 부위와 인접한 백악법랑경계 그리고 병소의 심부에 응력이 집중되었다. 2. 응력의 집중을 보였던 병소의 금심부근과 심부는 수복 후 응력이 많이 감소하였으며 대신 다른 부위에서는 응력이 약간 증가하였다. 3. 병소의 근심부위와 심부는 흐름형 복합레진으로 수복하였을 때 보다 혼합형 복합레진으로 수복하였을 때 응력이 더 많이 감소하였다.
