项目摘要

The application of the dental implant to the tooth loss mending increases in the daily clinic now. It is thought that movement of dental implant different from natural teeth is done at the clenching because the periodontal ligament organization is lacked in the dental implant compared with natural teeth. However, it is a current state that there is no standard based on scientific research as for the occlusal contact to the superstructure.In this research, we aimed to examine the influence of the occlusal contact on the superstructure exerted on the stability of the occlusion in the intercuspal position. It was examined whether existing occlusal examination methods were able to use for the evaluation of the implant because there was a necessity for objectively catching a long series of occlusal contact and implant's changes for that. Moreover, to evaluate the change in the state of osseointegration when long-term passage in the patient treated with implant was observed, the IM checker was developed.As a result, the utility of the add-picture method and T-Scan II was shown in occlusal contact's evaluation and the utility of the IM checker was shown in the implant mobility evaluation. Implant patient's state of the occlusal contact was shown with occlusal evaluation equipment, and the occlusal contact when clenching strength was raised stabilized, and showed the tendency same as a healthy volunteers. The influence on the IM value whose diameter and depth of the implant body are the implant mobility indices in the model experiment was examined about the IM checker. Horizontal direction and the vertical direction were excited to the implant body and the measurement was evaluated. It was suggested the IM checker was able to measure implant's mobility, and this mobility to be able to evaluate the level of osseointegration.
种植体在牙缺失修复中的应用日益增多。人们认为,种植牙的运动不同于天然牙齿是在咬紧时完成的,因为与天然牙齿相比,种植牙中缺乏牙周膜组织。然而,目前关于咬合接触对上结构的影响尚无科学依据,本研究旨在探讨牙尖交错位上结构咬合接触对咬合稳定性的影响。研究了现有的咬合检查方法是否能够用于种植体的评价,因为有必要客观地捕捉一系列咬合接触和种植体的变化。此外,为了评估长期通过种植体治疗的患者中骨整合状态的变化,开发了IM检查器,结果显示,添加图片法和T-Scan II在咬合接触评估中的实用性,以及IM检查器在种植体活动度评估中的实用性。用咬合评价仪显示种植体患者的咬合接触状态,咬合力提高后咬合接触趋于稳定,与健康志愿者的趋势一致。以种植体直径和种植体深度作为模型实验中种植体移动性的指标,考察了IM检查器对IM值的影响。对种植体进行水平方向和垂直方向的激励,并对测量结果进行评价。这表明IM检查器能够测量种植体的活动度,并且该活动度能够评价骨结合水平。
