结局指标
主要结局
change from baseline in pain, as measured by Numerical Rating Scale (NRS)
时间窗: Baseline, 7 days
Pain was evaluated postoperatively at the day of surgery, 3rd and 7th day post-surgically Numerical Rating Scale (NRS). Numerical Rating Scale (NRS) is a simple, widely used tool, typically an 11-point scale (0-10), where patients rate their pain intensity, with 0 meaning "no pain" and 10 meaning "worst imaginable pain,".
change from baseline of edema
时间窗: baseline, 7 days
Edema was evaluated with the aid of tape measure (in centimeters). Three measurements were performed on the patient's operated site preoperatively, 3rd and 7th day after surgery. The evaluation of edema was done by subtracting the total value of the three measurements obtained postoperatively (at 3rd and 7th day) from the total value of the three measurements obtained at pre-operative baseline. The three measuring lines are: 1. Lateral corner of the eye-angle of the mandible. 2. Tragus-outer corner of the mouth. 3. Tragus pogonion.
change from baseline in Grafted sinus height (GSH)
时间窗: baseline, 12 months
CBCT was made preoperatively, immediately after sinus augmentation (T0) and 6 months after loading (T12) for evaluation of Grafted sinus height (GSH): the distance between the original sinus floor to the new sinus floor regarding crestal cortical line.
change of implant stability, as measured by osstell
时间窗: baseline, 12 months
Stability was measured with osstell (ISQ) immediately after implant placement (T0) after 12 months (T12). ISQ is a scale that ranges from 1 to 100 and is used to assess implant stability. Scales greater than 70 ISQ indicate a high level of stability, scales between 60 and 69 means medium stability and scales \>60 ISQ are considered as low stability.
