研究目的: |
本技术拟使用永久修复体对初期稳定性良好的单颗种植体进行即刻负荷,以期能在在保证种植修复治疗效果的前提下缩短患者治疗周期,尽早恢复单颗后牙缺失患者的咀嚼功能。 |
||||||||||||||||||||||
|
Objectives of Study: |
This technology intends to use permanent restorations to immediately load a single implant with good initial stability, in order to shorten the patient's treatment cycle and restore chewing function in patients with single posterior tooth loss as early as possible while ensuring the effectiveness of implant restoration treatment. |
