窄直径种植体在下颌前牙区临床疗效的回顾性研究

A Retrospective Study on Clinical Performance of Narrow Diameter Implant in Mandibular Anterior Region

目的:回顾性分析下颌前牙区应用窄直径种植体的临床疗效。方法:纳入下颌前牙区植入窄直径种植体的患者149例,种植体227颗。检查指标包括种植体存留率、并发症情况、美学评分及边缘骨吸收。结果:窄直径种植体存留率为98.68%;随访期间软硬组织情况较好,美学效果均较为满意;种植体边缘骨吸收量为(0.28±0.41)mm,口腔卫生情况、牙周病及吸烟是影响骨吸收的风险因素。结论:下颌前牙区应用窄直径种植体的临床效果理想可靠。严格控制风险因素、合理制定种植方案、定期随诊维持疗效是成功的关键。

Objective:To analyze the clinical curative effect of narrow diameter implant in mandibular anterior region retrospectively.Methods:A total 227 implants in 149 patients with narrow diameter implants in mandibular anterior region were enrolled in this study.The clinical examination indexes included implant survival rate,complications,pink-white esthetic score,and marginal bone loss.Results:The cumulative survival rate of narrow diameter implant was 98.68%.Soft and hard tissues were in good condition,and aesthetic effectiveness was satisfactory during the follow-up.Marginal bone loss was(0.28±0.41)mm,which was affected by oral hygiene,periodontal disease,and smoking.Conclusion:The clinical effect of narrow diameter implant in mandibular anterior region is ideal and reliable.The key to the success of implant supported dentures is to strictly control the risk factors,reasonably formulate the plan of implant restorations,and follow-up regularly to maintain the curative effect.
