It is necessary to examine think about occlusion by osseointegrated implant prostheses more strictly than natural teeth because there is no periodontal ligament.We analyzed the three-dimensional occlusal force vectors during intercuspation in normal adults. Silicone occlusal registration and pressure-sensitive sheets were recorded for ten subjects during clenching with medium force and maximum force. A non-contact, three-dimensional measuring device digitized the silicone occlusal registration and occlusal forces were measured using pressure-sensitive sheets. After the occlusal contact position had been identified, the three-dimensional occlusal force pattern was synthesized from the data.The contact points, contact areas, resultant forces and moments for the molars were significantly different from those for the premolars. The inclination of resultant forces were almost vertical to the occlusal plane in the frontal and sagittal view.There was also a significant difference in the contact points, contact areas, resultant forces and moments when clenching with medium force was compared with clenching with maximum force. However, there was no consistant tendency in the inclination of the resultant forcesWe were able to clarify occlusal contact of natural teeth in detail. It is thought that this can be applied to osseointegrated implant prostheses.

由于没有牙周膜的存在，骨整合种植体修复的咬合关系需要比天然牙更严格的检查和考虑。记录了10名受试者在中等力和最大力的咬紧过程中的硅胶咬合记录和压敏片。使用非接触式三维测量装置对硅树脂咬合配准进行数字化，并使用压敏片测量咬合力。在确定咬合接触位置后，根据数据合成三维咬合力模式，磨牙和前磨牙的接触点、接触面积、合力和力矩有显著差异。在矢状面和正矢状面上，合力的倾斜度几乎垂直于咬合平面，中等力与最大力咬合时的接触点、接触面积、合力和力矩也有显著性差异。11但合力的倾斜趋势并不一致，我们可以更详细地了解天然牙的咬合接触。据认为，这可以应用于骨整合种植体假体。
