简要总结
RESULTS - Evaluation of dimensional changes The results for the dimensional changes in master casts are displayed in Table 2. The mean dimensional difference between the 1-week and 6-month casts was -0.98 mm in the treatment group and -1.01 mm in the control group (P=0.050). The cast volume was lower at 6 months than at 1 week in both the treatment and control groups. - Quantity of bone tissue in CBCT The results for the normalized quantity of bone tissue (Q6/Q2) in the CBCT data are presented in Table 2. The mean percentage was 91.6% in the treatment group and 91.5% in the control group (P=0.050). There was less quantity of bone tissue at 6 months than at 1 week in both the treatment and control groups. - Changes in width and height in CBCT The changes in the width of the center of the extraction socket in CBCT data are displayed in Table 2. The mean difference in width between the V2 and V6 images was -1.7 mm in the treatment group and -2.1 mm in the control group (P=0.050).
