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.

为了建立口颌系统的客观测定，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．所有患者均承认佩戴义齿后咀嚼效率有所提高。此外，最大咬合力与咀嚼效率之间存在显着相关性。因此，建议检查咬合力或咀嚼效率有助于检查颌骨功能。2．结果表明，咀嚼肌活动的左右不对称性和髁突运动轨迹的稳定性对于口颌功能的详细检查是有效的。3．考察了提高下颌全口义齿刚度的有效加固结构，认为采用T型断面的铸模结构最为有效。 4．义齿咀嚼过程中的运动受残牙槽沟形态和咬合力作用在义齿上的位置的影响，可以通过改变义齿的种植位置来控制。5．在覆盖义齿佩戴者中，基牙上的水平压力受到根冠形状或数量变化的影响。
