Outcome:

Changes in the height of the ridge crest to the shoulder platform of the implant

Type:

Secondary indicator

测量时间点:

1-5年

测量方法:

使用Mimics软件,导入术前术后CBCT进行数字化测量和分析,计算唇侧骨嵴顶至种植体肩台高度变化值,边缘骨吸收。并通过术后随访调查患者满意度。

Measure time point of outcome:

1-5year

Measure method:

Using Mimics software, preoperative and postoperative CBCT were imported for digital measurement and analysis to calculate the height change value from the lingual crest to the implant shoulder and marginal bone resorption. Patient satisfaction was also investigated through postoperative follow-up.
