摘要
目的评价国产骨填充材料(牛煅烧骨)用于拔牙窝位点保存及种植骨增量的临床疗效。方法选取青岛大学附属医院种植中心就诊患者40例,前牙或前磨牙需拔除。采取双盲法将患者随机分为试验组(国产骨填充材料)和对照组(Bio-Oss骨填充材料)。患者行牙拔除术并在拔牙窝植入对应骨粉,术后即刻和术后6个月均拍CT,计算牙槽嵴垂直向和颊舌向骨吸收量,评价2种植骨材料骨增量的临床效果评价。结果两种材料均显示出了较好的结果,无感染及排斥反应。CT示实验组和对照组患者的成骨效果佳,组间无明显差异(P>0.05)。结论国产骨填充材料(牛煅烧骨)牙槽嵴保存效果良好,值得临床推广。
Objective To evaluate clinical efficacy of domestic cattle calcined bone filling material (cattle calcined bone) for tooth extraction site preservation and bone increment.Methods In this study,40 patients with tooth extraction of anterior teeth or premolars from our hospital were selected as research object.This experiment adopted double-blind experimental method. The patients were randomly divided into experimental group (domestic filling material) and control group (Bio-Oss bone filling meterial).The patients were treated with tooth extraction and implanted with the corresponding bone materials in the tooth socket.The height and width of bone resorption of the alveolar ridge were measured by CT immediately after the operation and 6 months after the operation.The clinical effects of two bone materials were evaluated.Results Both materials showed good results without infection and rejection.CT showed good osteogenic effect in experimental group and control group,with no significant differences between two grups (P>0.05).Conclusion Domestic cattle calcined bone filling material is useful for tooth extraction site preservation and bone increment.
