摘要: 目的 通过建立动物模型,验证2型糖尿病个体即刻种植即刻修复的可行性,并评估其预后。方法 应用新西兰兔构建2型糖尿病动物模型作为实验组,以健康新西兰兔为对照组,2组均进行即刻种植即刻修复,通过Micro-CT扫描、硬组织切片染色及分析、实时定量PCR检测炎症相关因子,对比2组的预后及组织学改建有无差异。结果 2组实验兔即刻种植即刻修复后种植体留存率均为90%,术后早期(2个月内)实验组种植体周骨质在各项微观参数中与对照组存在显著差异,同时术后1个月实验组种植体周软组织内IL-6、IL-33与TNF-α的表达显著高于对照组。结论 动物实验表明2型糖尿病动物模型应用即刻种植即刻修复后具有较好的安全性,但种植体早期骨结合形成缓慢、种植体周软组织炎症更为明显。

Abstract: Objective To investigate the feasibility and prognosis of immediate implant placement and immediate restoration in patients with type 2 diabetes by establishing an animal model. Methods The type 2 diabetic animal model was established using New Zealand rabbits as the experimental group and healthy New Zealand rabbits as the control group. Both groups underwent immediate implantation and immediate repair. Micro-CT scanning, hard tissue section, and detection of relative inflammatory factors by real-time quantitative PCR were used to compare prognosis and histological remodeling between the two groups. Results The success rate for immediate implant placement and immediate restoration was 90% in both groups. In the early postoperative period (1~2 months), the peri-implant bone of the experimental rabbits in the T2DM group was significantly different from the control group in various microscopic parameters, in the meantime, the expressions of IL-6, IL-33 and TNF-α were significantly higher than those of the control group. Conclusion Animal experiments have shown that the immediate implant placement and immediate prosthesis are safe in type 2 diabetic animal models. However, attention should be paid to the slow formation of osseointegration and obvious inflammation of the soft tissue around the implant in the early stage.
