香肠技术在刃状牙槽嵴中的水平骨增量效果研究

目的　在刃状牙槽嵴患者中应用香肠技术，评估其水平骨增量效果并为临床提供参考。方法：纳入杭州口腔医院种植科缺牙区剩余牙槽骨宽度窄于5 mm的患者12例，共包含18个水平骨增量位点。收集患者术前、术后即刻、术后9月种植位点的CBCT数据，通过6D Dental Planning Software进行拟合，测量距术前牙槽嵴顶中点垂直向距离1mm、3mm、5mm、7mm位点处的牙槽骨宽度。SPSS25.0 软件进行统计学分析。结果：1mm、3mm、5mm、7mm截面处术后9月较术前牙槽骨水平骨量平均增加量分别为2.26mm；3.13mm；3.17mm；2.81mm。术后9月骨量较术前骨量进行单因素方差分析（邦弗伦尼Bonferroni）：1mm、3mm、5mm、7mm截面处术后9月骨量较术前有显著增加，且有统计学意义(F=36.83；P<0.05)；(F=76.13；P<0.05)；(F=57.29；P<0.05)；(F=24.10；P<0.05)。结论：香肠技术可有效改善刃状牙槽嵴水平向骨缺损问题。

Study on the incremental effect of Bio-Gide Collagen Membrane GBR technique on horizontal bone defect

Objective　 Sausage technique was applied in patients with knife-edge ridge to evaluate the effect of horizontal bone increment and provide clinical reference. Methods Twelve patients with residual alveolar bone width less than 5mm in the edentulous area at the Department of Implant, Hangzhou stomatological hospital were included, containing 18 horizontal bone increment sites. Planting sites’ CBCT data were collected, including preoperative data, data immediately after operation and 9 months of postoperative. It was fitted by 6D Dental Planning software. The width of alveolar bone was measured at vertical distance 1 mm, 3 mm, 5 mm and 7 mm from the midpoint of alveolar crest. SPSS25.0 software was used for statistical analysis. Result At 1mm, 3mm, 5mm and 7mm sections, the average increase of bone mass at 9 months postoperative compared with preoperative respectively was 2.26mm, 3.13mm, 3.17mm and 2.81 mm. Bone mass at 9 months of postoperative was compared with preoperative bone mass by One-way analysis of variance (Bonferroni). The bone mass of 1mm, 3mm, 5mm and 7mm sections at 9 months of postoperative was significantly increased compared with preoperative, and there was statistical significance (F=36.83；P<0.05)；(F=76.13；P<0.05)；(F=57.29；P<0.05)；(F=24.10；P<0.05). Conclusion Sausage technique can effectively improve horizontal bone defect of the knife-edge ridge.
