简要总结
This study retrospectively evaluated the effect of two different lateral window preparation techniques on peri-implant bone augmentation for patients who underwent lateral sinus floor elevation with simultaneous implant placement using two-dimensional and three-dimensional radiographic results, with special emphasis placed on the stability of the graft material after surgery.

结局指标
主要结局
Apical bone height
时间窗: Immediately after surgery, and 6 months after surgery
The distance (mm) from the implant apex to the most apical position of the graft material along the longitudinal axis of the implant
Endo-sinus bone gain
时间窗: Immediately after surgery, and 6 months after surgery
The distance (mm) from the level of the sinus floor (middle of the buccal level and palatal level) to the level of the most apical position of the graft material along the longitudinal axis of the implant
Buccal bone height
时间窗: Immediately after surgery, and 6 months after surgery
The vertical distance (mm) from the api- cal margin of the implant shoulder on the buccal side straight up to the position of the most apical position of the graft material
Palatal bone height
时间窗: Immediately after surgery, and 6 months after surgery
The vertical distance (mm) from the api- cal margin of the implant shoulder on the palatal side straight up to the position of the most apical position of the graft material
Augmentation volume
时间窗: Immediately after surgery, and 6 months after surgery
The volume of the endo-sinus reconstructed graft materials
次要结局
- Early implant loss(6 months after surgery)
- Lateral bone length(Immediately after surgery, and 6 months after surgery)
- Perforation incidence(During the surgery)
- Lateral window length(Immediately after surgery, and 6 months after surgery)
