测量指标:

Outcomes:

指标中文名:

术后 24 周牙槽骨高度的变化

指标类型:

主要指标

Outcome:

Change in Alveolar Bone Height at 24 Weeks Postoperatively

Type:

Primary indicator

测量时间点:

测量方法:

使用CBCT 评估手术后 24 周牙槽骨高度的变化,术后 CBCT(术后 1 天内)牙槽骨高度值记为 H1 ,术后 24 周CBCT 牙槽骨高度值记为 H2 。高度参考面,以颌骨最低平面为参考,从拔除牙及近中和/或远中邻牙的颊侧龈缘中点到该平面的垂直高度设为 H ,牙槽骨高度变化△H=H1-H2。
