指标中文名:

种植体颊侧骨宽度和高度

指标类型:

主要指标

Outcome:

Peri-implant buccal lateral bone width and height

Type:

Primary indicator

测量时间点:

种植术后,种植戴牙,最终随访

测量方法:

参考岑雯的测量方法,以种植体的长度作为参照,对影像进行校准,然后以种植体的颈部平台为参考平面,过种植体顶端和末端分别做两条平行线a和b,过种植体长轴做a和b垂线可得线段cd,在种植体最大径处做a垂线可得线段ef(测得长度为种植体颊侧骨高度)(图4)。在单纯锥度固位种植体平台顶端a平行线上与斜肩的交点记作h,测量gh为平齐颈部平台颊侧骨宽度,在e点下方1mm处,测量ij记作种植体平台下1mm处颊侧骨

Measure time point of outcome:

Post-implant surgery, implant wear, final follow up

Measure method:

Referring to the measurement method of Wen Cen , the image was calibrated by using the length of the implant as a reference, and then the neck platform of the implant was used as a reference plane, two parallel lines a and b were made over the apical and end of the implant, respectively, and two plumb lines a and b were made over the implant's long axis to obtain the line segment cd, and a plumb line a was made over the implant's maximal diameter to obtain the line segment ef (the length of whic
