摘要: 目的 评价使用浓缩生长因子(concentrate growth factors,CGF)联合Bio-oss骨粉在上颌前牙区进行拔牙位点保存的临床效果。方法 选取需要拔除上颌前牙的病人26例共32颗牙,根据性别分层,采用数字表法随机分为2组,试验组(CGF组,16颗)拔牙窝内植入CGF和Bio-oss骨粉混合物,CGF膜关闭拔牙窝;对照组(自然愈合组,16颗)拔牙窝搔刮后放置止血海绵,待其自然愈合。病人于术后6个月时复诊,拍摄锥形束计算机断层扫描(cone beam computed tomography,CBCT),分别与术前CBCT比较,观察并测量拔牙位点牙槽骨高度和宽度的变化。结果 在CGF组,唇、腭侧骨板高度术后6个月和术前相比,差异无统计学意义(P>0.05),牙槽嵴宽度术后6个月和术前相比,差异有统计学意义(P<0.05);在对照组,唇、腭侧骨板高度和牙槽嵴宽度术后6个月和术前相比,差异均具有统计学意义(P<0.05);2组间比较,唇、腭侧骨板高度和牙槽嵴宽度的变化差异有统计学意义(P<0.05)。结论 CGF联合Bio-oss骨粉进行拔牙位点保存可以有效地维持牙槽嵴的宽度和高度,为种植修复创造有利条件。

Abstract: Objective To evaluate the clinical effect of site preservation by using concentrate growth factors (CGF) combined with Bio-oss bone powder in maxillary anterior region. Methods Thirty-two maxillary anterior teeth of 26 patients that should be extracted were randomly divided into two groups. For CGF group(16 cases), CGF combined with Bio-oss was implanted into teeth extraction socket, then covered the socket with CGF membrane; for control group(16 cases), teeth extraction socket was placed with hemostatic sponge after scoraping. Cone beam computed tomography (CBCT) should be taken after 6 months, then compared with preoperative, observed and measured the change of width and height of the alveolar bone at extraction site. Results In CGF group, the heights of labial and palatal bone plates between 6 months after surgery and preoperative were no statistically significant (P>0.05), and the widths between 6 months after surgery and preoperative were statistically significant (P<0.05). In control group, the heights of labial and palatal bone plates and the widths between 6 months after surgery and preoperative were statistically significant (P<0.05). The differences of changes between the two groups were statistically significant (P<0.05). Conclusion CGF combined with Bio-oss being used for preservation of teeth extraction site, which may effectively keep the width and height of alveolar ridge, it is favorable for implanting and repairing.
