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.
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.
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).
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.
探讨预成型钛网联合浓缩生长因子（CGF）膜在前牙骨量不足种植修复中的应用效果。
选取2017年1月至2020年2月来院就诊的62例前牙骨量不足患者，采用计算机数字表法分为实验组（n=31）和对照组（n=31）。两组患者均采用种植修复。对照组在种植修复后用预成型钛网覆盖骨缺损区，实验组在种植修复后用预成型钛网联合CGF膜覆盖骨缺损区。随访12个月后，统计两组成功率。比较两组术后6个月的牙槽嵴高度、骨增量、牙槽骨密度、骨厚度、粉色美学指数（PES）及并发症情况。采用SPSS 19.0软件包进行统计学分析。
随访12个月期间，两组种植成功率均为100%，无种植体松动或脱落。两组术前牙槽嵴高度比较，差异无统计学意义（P>0.05）。实验组术后牙槽嵴升高及骨增量明显高于对照组（P<0.05）。两组术前牙槽骨密度及骨厚度比较，差异无统计学意义（P>0.05）。两组术后6个月及12个月牙槽骨密度及骨厚度均明显低于术前（P<0.05）。两组术后6个月牙槽骨矿物质密度均明显低于术后12个月（P<小0.05），两组术后6个月牙槽骨厚度均明显高于术后12个月（P<0.05）。实验组术后6个月及12个月牙槽骨密度及骨厚度均明显高于对照组（P<0.05）。实验组术后PES评分明显高于对照组（P<0.05）。两组术后6个月并发症总发生率比较，差异无统计学意义（P>0.05）。
预成型钛网联合CGF膜用于前牙骨量不足患者的种植修复，效果确切。可增强种植修复的美观效果，改善术后骨代谢，安全可靠。
