Stress analysis of maxillary central incisor crown implant restoration in different occlusal modes

doi:10.12307/2022.093

Abstract

Abstract: BACKGROUND: In the treatment of oral implant repair, different occlusal contact methods affect the internal structure of the implant and the stress distribution in the bone tissue. Whether the stress distribution is balanced or not determines the long-term life of the implant and the stability of the surrounding bone level.
OBJECTIVE: To explore the effects of different occlusal contact modes on the internal stress distribution of restoration, implant, abutment, retention screw, bone tissue, binder and restoration in three kinds of occlusal relationship of maxillary central incisor implant.
METHODS: The cone beam CT image data of one volunteer undergoing implant restoration of the maxillary central incisor were extracted from the database. Mimics 19.0 software was utilized to build the maxillary model, and the maxillary model was imported into Solidworks 2017 software to build the maxillary central incisor crown restoration model. Using ANSYS Workbench 17.0 software, three occlusal contact modes of end-to-end occlusion, normal occlusion, and deep overbite occlusion were loaded by simulating the distal middle edge of the crown, the midpoint of the implant diameter and the midpoint of the joint crown. The stress distribution of each structure and bone tissue in the implant restoration was analyzed under the influence of three kinds of occlusal relationship and three loading modes.
RESULTS AND CONCLUSION: (1) In the end-to-end occlusion group, when the contact mode changed from the distal margin to the midpoint of the implant diameter and the midpoint of the crown, the stress of the internal structure, bone tissue and binder of the implant decreased accordingly. (2) In the normal group, when the contact mode changed from the distal margin to the midpoint of the implant diameter and the midpoint of the joint crown, the stress of the internal structure, bone tissue and binder of the implant decreased accordingly. (3) In the deep overbite group, when the contact mode changed from the distal margin to the midpoint of the implant diameter and the midpoint of the crown, the stress of the internal structure and bone tissue of the implant increased accordingly, while the stress of the binder gradually increased. (4) The results show that different occlusal contact modes and occlusal relationship affect the distribution of stress in each structure, bone tissue and binder of implant restoration. This conclusion may provide a reference basis for the adjustment of occlusal contact of implant restoration.
