预成型钛网联合浓缩生长因子膜修复31例前牙种植区骨量不足的疗效分析

Effect of preformed titanium mesh combined with concentrated growth factor membrane on implant restoration of insufficient bone mass in anterior teeth of 31 consecutive cases

目的:探讨预成型钛网联合浓缩生长因子(CGF)膜修复前牙种植区骨量不足的疗效。方法:选择2017年1月—2020年2月就诊的前牙区骨量不足患者62例,依照电脑数字表法将其分为实验组(31例)与对照组(31例)。2组均采用种植修复,对照组种植后将预成型钛网覆盖于骨缺损区,实验组种植后将预成型钛网与CGF膜覆盖于骨缺损区。随访12个月,统计2组种植成功率,比较2组牙槽嵴高度、骨增量、牙槽骨骨密度、骨厚度、红色美学指数(PES)以及术后6个月内并发症发生情况。采用SPSS 19.0软件包进行统计学分析。结果:随访12个月,2组种植成功率均为100%,无种植体松动、脱落等现象。2组术前牙槽嵴高度相比差异无统计学意义(P>0.05),实验组术后牙槽嵴提升高度、骨增量显著高于对照组(P<0.05)。2组术前牙槽骨骨密度与骨厚度相比差异无统计学意义(P>0.05),术后6个月、12个月的牙槽骨骨密度与骨厚度均显著低于术前(P<0.05),术后6个月的牙槽骨骨密度均显著低于术后12个月(P<0.05),术后6个月牙槽骨骨厚度均显著高于术后12个月(P<0.05),且实验组术后6个月、12个月的牙槽骨骨密度与骨厚度均显著高于对照组(P<0.05)。实验组术后PES评分显著高于对照组(P<0.05)。术后6个月,2组并发症发生率相比无统计学差异(P>0.05)。结论:预成型钛网联合CGF膜用于前牙区骨量不足患者种植修复,疗效确切,可提升种植修复的美容效果,改善术后骨代谢,安全可靠。

PURPOSE:To explore the effect of preformed titanium mesh combined with concentrated growth factor(CGF)membrane on implant restoration of insufficient bone mass in the anterior teeth.METHODS:A total of 62 patients with insufficient bone mass in the anterior teeth who visited the hospital from January 2017 to February 2020 were selected,and they were divided into experimental group(n=31)and control group(n=31)according to computer digital table method.Both groups of patients used implant restoration.In the control group,the bone defect area was covered with a preformed titanium mesh after implant restoration,while in the experimental group,the bone defect area was covered with a preformed titanium mesh and CGF membrane after implant restoration.After 12 months of follow-up,the success rate of the two groups was counted.Alveolar ridge height,bone increment,alveolar bone density,bone thickness,pink aesthetic index(PES)and complications 6 months after surgery were compared between the two groups.SPSS 19.0 software package was used for statistical analysis.RESULTS:During the 12-month follow-up,the implantation success rate in both groups was 100%,and there was no implant loosening or dropping.There was no significant difference in the height of the alveolar ridge between the two groups before operation(P>0.05).The postoperative alveolar ridge elevation and bone increment in the experimental group were significantly higher than those in the control group(P<0.05).There was no significant difference in alveolar bone density and bone thickness between the two groups before operation(P>0.05).The alveolar bone density and bone thickness of the two groups 6 and 12 months after operation were significantly lower than those before operation(P<0.05).The alveolar bone mineral density 6 months after operation in both groups was significantly lower than that 12 months after operation(P<0.05),and the alveolar bone thickness 6 months after operation in both groups was significantly higher than that at 12 months after operation(P<0.05).The alveolar bone density and bone thickness of the experimental group 6 and 12 months after operation were significantly higher than those in the control group(P<0.05).The postoperative PES score of the experimental group was significantly higher than that of the control group(P<0.05).There was no significant difference in the total incidence of complications between the two groups 6 months after operation(P>0.05).CONCLUSIONS:Preformed titanium mesh combined with CGF membrane is used in implant restorations for patients with insufficient bone mass in the anterior teeth,and the effect is definite.It can enhance the cosmetic effect of implant restorations,improve postoperative bone metabolism,and is safe and reliable.
