测量指标:

Outcomes:

指标中文名:

术后即刻水平骨增量

指标类型:

主要指标

Outcome:

The horizontal bone gain after the bone augmentation immediately

Type:

Primary indicator

测量时间点:

这是一项回顾性队列研究,未对患者治疗过程行任何干预,在所有患者资料收集完成后,由实验员统一对所有患者数据资料进行处理及测量

测量方法:

这是一项回顾性队列研究,所有测量均在患者完成治疗后进展,未对患者治疗过程行任何干预。本研究在收集患者资料后,两名研究员独立通过mimics软件对患者的术前及术后即刻CBCT数据进行匹配、叠加、测量等分析,获得距种植体颈部0,2,4mm的术后即刻水平骨增量。

Measure time point of outcome:

After all patient data was collected, the analyses were uniformly performed at the end of the study.

Measure method:

This was a retrospective cohort study. All measurements were performed after completion of treatment, and no intervention was applied during the treatment process. After collecting patient data, two investigators independently used Mimics software to match, register, and superimpose preoperative and immediate postoperative CBCT datasets, and then conducted the measurements and analyses to obtain the immediate postoperative horizontal bone gain at the 0,2,4 mm level referenced to the implant neck
