单牙缺失伴根方水平向骨量不足的微创种植修复

Microinvasive dental implantation and restoration with single tooth loss and root level horizontal bone deficiency

目的:探讨不同原因导致种植体入路受限的患者的种植体选择与修复方式。方法:选用形态与根方水平向骨量不足区域相适应的一段式锥状种植体或者两段式小直径种植体,通常采用不翻瓣的微创种植技术完成手术,一段式锥状种植体术后调磨基台并临时修复,两段式小直径种植体术后酌情做隐形义齿临时修复(前牙区)或者不修复(后牙区),3~5月后完成永久修复。结果:一段式锥状种植体的即刻修复,给患者带来了美观性和舒适性,增强了患者的自信心。后期的永久修复,无论从牙冠形态或者质感或者牙冠颈部的萌出感,都更接近天然牙,患者的满意度高。结论:对于缺牙间歇变小或者根方水平向骨量不充分的患者,选用与之形态相匹配的锥状或小直径种植体并采用微创种植手术与修复技术,既可简化手术设计、减少创伤、同时又能获得良好的修复效果,是一种值得推荐的方法。

Objective:To explore choices of implants and restoration for patients with single tooth loss and root level horizontal bone deficiency due to different reasons.Methods:Employ one-stage conical implant or combined small-diameter implants which match root level horizontal bone deficiency,and adopt flapless microinvasive implantation techniques to perform operations.Then polish abutment and finish immediate restoration for one-stage conical implant,or perform temporary restoration to anterior teeth using aesthetic denture(no restoration to posterior teeth)and permanent restoration 3~5 months after the combined small-diameter planting operation.Results:The immediate restoration using one-stage conical implant brings aesthetics,comfort and confidence to patients.From the aesthetic aspect,the permanent restoration gets the appearance,color and texture of crown closer to natural teeth and make patients more satisfied.Conclusion:Choose conical or small-diameter implants to match patients who suffer root level horizontal bone deficiency due to missing teeth or alveolar bone deficiency,and perform microinvasive operation and aesthetics restoration.This method can simplify the operation process,relieve much of the pain and achieve the aesthetic restoration effect,such that it is greatly recommendable.
