目的:本文目的是研究种植体周围骨缺损采用钛网治疗前后,患者临床和影像学的特征的变化。方法:对12例应用钛网的种植手术进行前瞻性观察研究。收集患者信息、诊断及手术资料,在术前、Ⅰ期术后、Ⅱ期术前三个时间点,通过CBCT观察术区骨量变化,记录种植体成活以及并发症。结果:患者种植时均有骨缺损,应用钛网后术区再生骨量好,种植体均成活,仅一例在I期术后和II期术前出现钛网暴露。12例种植体均成功。讨论:钛网在有骨缺损的种植治疗中有较好的效果,然而治疗过程中存在钛网暴露这一主要并发症。但I期术后钛网晚期暴露并不明显影响成骨及种植体成活。结论:钛网应用对于成骨有良好效果,延迟的钛网暴露对成骨和种植效果无明显不良影响。
OBJECTIVE: The aim of this study was to investigate the clinical and radiological features of patients with and without titanium mesh implant defects. Methods: Twelve cases of titanium mesh implant surgery were prospectively studied. The patients’ information, diagnosis and operation data were collected. The bone mass changes were observed by CBCT at three preoperative, preoperative, postoperative phase Ⅰ and Ⅱ phases. The survival and complications of the implant were recorded. Results: All the patients had bone defects at the time of implantation. The regenerated bone volume was good and the implants survived after the titanium mesh was applied. Only one case had titanium mesh exposure before the operation of Phase I and II. All 12 implants were successful. Discussion: Titanium mesh in the treatment of bone defects have a good effect in the treatment, however, there is the treatment of titanium mesh exposed this major complication. However, the late exposure of titanium mesh in stage I did not significantly affect the survival of osteoblasts and implants. Conclusion: Titanium mesh application has good effect on osteogenesis. Delayed titanium mesh exposure has no obvious adverse effect on osteogenesis and planting.
