【摘要】：目的:评价应用双螺纹宽螺距种植体进行后牙区即刻负载的临床效果。方法:种植体植入后即刻负载,植入后3个月、6个月、12个月时对其成功率、种植体颈部骨吸收情况、牙龈乳头高度及软组织炎症等方面进行评价。结果:即刻负载种植体在3个月、6个月、12个月时均无松动,种植体周围无X线透影区,种植体成功率100%。种植体颈部边缘有骨吸收,3个月平均吸收0.15mm,6个月平均吸收0.31mm,12个月平均吸收0.4mm。种植体周围牙龈乳头高度恢复良好,平均牙龈乳头指数3。2例患者临时冠修复时出现种植体周围黏膜炎,最终修复后种植体周围软组织未见明显炎症。结论:后牙区应用双螺纹宽螺距种植体进行即刻负载有良好的临床效果,但是其长期效果还需进一步观察。
[Abstract]:Objective: to evaluate the clinical effect of double thread wide pitch implants for immediate loading of posterior teeth. Methods: the success rate, neck bone resorption, gingival papilla height and soft tissue inflammation were evaluated at 3 months, 6 months and 12 months after implant implantation. Results: there was no loosening of the implants at 3 months, 6 months and 12 months. There was no X-ray area around the implants, and the implant success rate was 100%. Bone resorption occurred at the neck edge of the implant, with an average absorption of 0.15 mm in 3 months, 0.31 mm in 6 months and 0.4 mm in 12 months. The height of gingival papilla around implants recovered well. The mean gingival papilla index of 3.2 patients with temporary crown repair appeared periimplant mucositis, but there was no obvious inflammation in the soft tissue around implants after the final restoration. Conclusion: double thread wide pitch implant has good clinical effect in posterior region, but its long-term effect needs further observation.
