摘要: 目的:探讨使用羟基磷灰石骨粉复合生物胶原材料进行拔牙位点保存的临床效果。方法:对30例拔除前牙的患者随机分组,试验组15例,拔牙同期在拔牙窝内植入羟基磷灰石骨粉,生物胶原材料覆盖表面关闭拔牙窝,临时义齿修复缺失牙并在位点处维持软组织形态;对照组15例,拔牙后常规处理,让拔牙窝内充满自然形成的血凝块。6个月后复诊,观察拔牙窝愈合情况,测量牙槽嵴的高度、宽度和牙间乳头的位置,采用两独立样本t检验进行统计学分析,使用SPSS17.0统计学软件分析处理数据。结果:试验组拔牙窝愈合良好,牙槽骨丰满,牙龈乳头形态得以保留,牙龈边缘连续一致;而对照组牙槽嵴吸收、萎缩,高度降低、宽度缩小明显,牙龈乳头萎缩甚至消失。实验组和对照组间牙槽嵴高度、宽度和牙间乳头的变化差异均具有统计学意义(P<0.05)。结论:羟基磷灰石骨粉复合生物胶原材料起到了保存拔牙后牙槽骨骨量的作用,及时的临时义齿修复很好的维持了软组织形态。

Abstract: Objective: To study the clinical effect of coral hydroxyapatite combined with biological collagen material in socket preservation. Methods: Thirty patients were assigned into two groups in a randomized controlled clinical trial. Experimental group: socket preservation with coral hydroxyapatite combined with biological collagen material in the extraction socket. Control group: conventional treatment after tooth extraction. All the patients came back after 6 months since tooth extraction, and the height and width of the alveolar ridge were measured to observe the socket healing condition. The t-test was used to analyze the variations between the experimental group and the control group. Results: In the experimental group, the gingival color and shape were in coordination with the adjacent tooth. Whereas the control group showed alveolar ridge absorption and atrophy with decreased height and notably narrowed width. The mean value changes of alveolar ridge height, width and gingival were statistically significant different between two groups (P<0.05). Conclusion: Coral hydroxyapatite combined with biological collagen material can preserve the bone quantity after tooth extraction for implant prosthesis and they were suitable materials for socket preservation.
