Description

A removable dental prosthesis anchored to dental implants using ball-and-socket or bar-and-clip retention mechanisms, providing enhanced stability and function for edentulous patients.

Main Uses

用于全口或半口牙列缺失患者的种植支持式可摘义齿修复；改善传统全口义齿固位差、稳定性弱、咀嚼效率低等问题；适用于骨量中等、全身状况稳定但无法耐受固定桥或All-on-4即刻负重的中老年患者；作为过渡性或终末期修复方案，兼顾功能恢复、维护便利性与成本效益。

Normal Range

种植覆盖义齿（球帽/杆卡式）为口腔修复治疗项目，非生物学检测指标，无传统意义上的‘正常值范围’。其临床评价标准为：固位力≥3N（牛顿），稳定性达临床可接受水平（无明显翘动、旋转或下沉），咬合接触点均匀分布（8–12个稳定接触点），垂直距离维持误差≤0.5mm，基台-义齿连接间隙≤50μm（显微测量），患者主观满意度≥90%（VAS评分）。上述参数属工程学与功能学评估范畴，非实验室检验数值。
