This study involved a randomized clinical trial that included 140 patients. Alveolar ridge preservation was performed with xenografts. Sealing in the control group consisted of a collagen membrane versus cyanoacrylate in the test group. The dental implants were placed immediately after extraction. The variables were evaluated at 3, 12, and 18 months of follow-up. Pearson's chi-squared test was used for qualitative variables and the Student t-test for related samples was used for quantitative variables. The change in buccolingual alveolar bone width was significantly greater in the CMX group than in the CX group after three months ( < 0.005). However, significance was not reached at the other follow-up timepoints ( > 0.005). CAL showed significantly greater values in the CMX group than in the CX group ( < 0.005), and MBL proved greater in the CMX group than in the CX group, with < 0.001. Five membrane exposures were recorded in the CMX group. Cyanoacrylate as a sealing method for alveolar ridge preservation seems to afford better clinical and radiological results than collagen membrane.
本研究包括一项随机临床试验，纳入了140名患者。采用异种移植物进行牙槽嵴保存。对照组的封闭材料为胶原膜，试验组为氰基丙烯酸酯。拔牙后立即植入牙种植体。在随访3个月、12个月和18个月时对各项变量进行评估。定性变量采用Pearson卡方检验，定量变量采用相关样本的Student t检验。3个月后，CMX组颊舌向牙槽骨宽度的变化显著大于CX组（<0.005）。然而，在其他随访时间点未达到显著性（>0.005）。CMX组的临床附着水平（CAL）显著高于CX组（<0.005），CMX组的探诊深度（MBL）也大于CX组，差异有统计学意义（<0.001）。CMX组记录到5次膜暴露。氰基丙烯酸酯作为牙槽嵴保存的封闭方法似乎比胶原膜能提供更好的临床和影像学结果。
