Development of the Overall Diagnosis System in Stomatognathic System as the objective determination

为建立口腔颌系统的客观测定方法，寻找诊断颌骨功能的有效参数和长期稳定工作的义齿设计标准。主要结果如下：1。所有患者佩戴义齿后，咀嚼效率均有改善。最大咬合力与咀嚼效率呈显著相关。因此，建议通过检查咬合力或咀嚼效率来检查颌骨功能。结果表明，咀嚼肌活动的左右不对称和髁突运动轨迹的稳定性对口腔功能的详细检查是有效的。通过对提高下全口义齿刚度的有效加固结构的研究，认为采用T型截面的铸型结构对提高下全口义齿刚度效果最好。4 .残脊形态和咬合力作用在义齿上的位置影响义齿咀嚼时的运动，可以通过改变义齿种植位置来控制。在假牙佩戴者中，改变根冠的形状或数量会影响基牙的水平压力。

In order to establish the objective determination in stomatognathic system, we gave the searching for the effective parameter for the diagnosis of the jaw function and for the design standard of denture that would be work stably for a long time. The main results were as follows :1. Wearing the denture, the improvement of the masticatory efficiency was admitted in all patients. And more, the significant correlation was found between the maximum bite force and the masticatory efficiency. So, it was suggested that examining the bite force or the masticatory efficiency was useful to check the jaw function.2. It was shown that the right and left asymmetry in masticatory muscle activity and the stability in the locus of condylar movements are effective for detailed inspection on stomatognathic function.3. Examining the effective reinforcement structure to raise the stiffness of lower complete denture, it was suggested that applying the casts structure with T style section was most effective for that.4. The movement of denture during chewing was influenced by the forms of residual ridge and the position of biting force effected on the denture, and it could be controlled by changing the planting position of the artificial teeth.5. In over denture wearers, the horizontal pressures on the abutment tooth was influenced by changing the shape or the number of root cap.
