固位 [口腔] retention
maintenance
- 在固位、稳定及咀嚼功能的恢复上与传统可摘局部义齿无明显差异;
They don't have obvious difference in retention, stabilizing and the recovery of mastication function. - 目的测定卡环与牙面间的静摩擦系数,为卡环固位力的定量计算奠定基础。
Objective The friction coefficient between the clasp and enamel was measured as one base of calculating the retention force of clasp quantitatively. - 结论在卡环弹性极限内,金合金卡环固位力与卡环臂进入基牙倒凹的深度成正比。
Conclusion Within the elastic limit of the material, the relation between the retention of gold alloy clasp and the depth of abutment undercut showed positive correlation.
