occlusal rest meaning in Chinese
咬支托
支托
Examples
- Objective : to test the rationale for designing an occlusal rest for a distal - extension removable partial denture
摘要目的：探讨末端游离缺损义齿（牙合）支托设计的理论基础。 - Conclusion : the experiment , from the point of biomechanics , provides the theoretical basis for the stress distribution of occlusal rest design and further proves the advantages of mesial occlusal rest
结论：从生物力学角度为（牙合）力分配和（牙合）支托设计等提供了理论依据，进一步论证了近中（牙合）支托的优越性。 - Results : 1 ) under the same condition of loading , the stress and displacement of mesial occlusal rest design was smaller than that of distal occlusal rest design in abutment teeth and soft tissue under the base , however , the magnitude in the soft tissue under base was bigger . 2 ) when a distributed vertical load was applied to the artificial tooth abutment teeth regions , the stress distribution was similar to that of concentrated load in the artifitial tooth , and stress magnitudes were higher . 3 ) under the condition tested , the mesial occlusal rest design caused the stresses that were more in line with the long axes of the abutment teeth than did the distal occlusal rest design
结果： 1 )在同一加载条件下，近中（牙合）支托设计与远中（牙合）支托设计相比，基牙及基托下软组织的应力和位移值减小；基托下软组织的应力和位移值大于基牙； 2 )基牙及义齿整体加载时，各基牙应力分布规律与人工牙加载相同，但应力值增大； 3 )近中（牙合）支托设计使基牙受力更趋于轴向。 - Methods : this experiment used finite element analysis ( fen ) in the design of mesial and distal occlusal rest of distal - extension partial removable denture and to test the magnitude of stress and displacement of abutment teeth and soft tissue under the base when under the vertical force of two conditions
方法：采用有限元法在末端游离缺损义齿的有限元模型上作远中、近中（牙合）支托设计，分别在人工牙及修复后的牙列（包括义齿及基牙）上作垂直向加载，测试基牙及基托下软组织的位移及应力值，通过测试结果作对比分析。
