Analysis of initial occlusal contacts of implant prostheses

咬合间隙、咬合负荷和咬合接触面积等力学因素对种植体治疗的长期成功至关重要。由于没有牙周膜和神经系统作为应激屏障，种植体牙体的轻微咬合不协调可能会引起许多问题。然而，对于种植体修复体的最佳咬合接触，仍有许多不清楚的地方。本研究的目的是探讨一种使用咬面积测量系统（bite Eye）评估咬合间隙的方法，以获得高的再现性和可靠性。研究结果表明，根据种植体的咬合强度，记录咬合负荷的变化可以正确地评估咬合接触。虽然早期的研究计划是用黑硅片记录咬合间隙，但现在有了新开发的咬面积测量系统（bite Eye）。通过使用这种方法，它可以更简单地测量并减轻患者的负担。本研究的目的是评估Bite Eye的有效性，在本研究中，研究是否可以通过肌电图同时使用咬合力测量系统（Occluzer）和咬面积测量系统（Bite Eye）来正确记录弱咬合到强咬合时的咬合负荷和咬合接触面积。因此，我们认为对于单颗中间缺失后牙种植体患者，咬合仪记录咬合强度在60mvc及以上为宜，Bite Eye修复时记录咬合强度在20- 60mvc为宜。结果种植体修复后即刻牙合间隙为90 μm。从现在开始，需要一个长期的研究来确定功能方面，并建立一个适当的闭塞指南。

Mechanical factors such as occlusal gap, occlusal load and occlusal contact area are most important for long-term successful of implant treatment. Slight disharmony of occlusion in implant prostheses may cause many problems because those have not a periodontal membrane and nerve system as a stress breaker. However, regarding the optimum occlusal contacts of implant prostheses, there are still many unclear points. The purpose of this study was to investigate an evaluating method of occlusal gaps using a bite area measurement system (Bite Eye) in order to obtain high reproducibility and reliability. It was examined that it would be possible to assess occlusal contacts correctly by recordingvariations of changes in occlusal load according to clenching strength of implant prostheses. Although occlusal gap recorded by a black silicon in the early research program, there were recorded by a bite area measurement system (Bite Eye) which were newly developed. By using this, it can measure simpler and can ease a patient's burden. The purpose of this study was to evaluate the effectiveness of a Bite Eye in this study, it was examined whether it would be possible to recordcorrectly the occlusal load and occlusal contact area from the weak clenching to the strong clenching by using together bite force measurement system (Occluzer) and bite area measurement system (Bite Eye) with Electromyograms. As a result, it was suggested that it was appropriat to record at the clenching level of 60 MVC or more strength by Occluzer, and at the clenching level of 20-60 MVC by Bite Eye prostheses restoring to the patients with an implant for a single intermediate missing posterior tooth. In the result occlusal gap of implant immediately after implant prostheses restoring were 90 μm. From now on, a long-term study is needed to determine the functional aspects and and to establish a guideline for adequate occlusion.
