Abstract

本实用新型提供一种使用材料弹性好、经济方便的根管桩核模型。其包括根管桩(1)、核(2)，根管桩(1)插入根管内起固位作用，根管口的唇面颈部做成弧形凹面，制备成0.5～1mm的肩台，舌面颈部做成45°斜面，核(2)是露在根管口外带冠的部分，与根管桩(1)相连接。采用这样的结构可以为残根、冠修复提供良好的固位形和抗力形，防止根管桩核的松脱。

Description

根管桩核模型
一、技术领域：本实用新型涉及一种医疗器械装置，尤其是一种根管桩核模型。
二、背景技术：现今临床工作中，对于残根、残冠经根管治疗后，一般采用嵌体蜡、嵌体蜡+不锈钢丝或嵌体蜡+竹签、硅橡胶等方法制作根管桩核模型。应用嵌体蜡、嵌体蜡+不锈钢丝或嵌体蜡+竹签等制作，存在取不到位、易变性等缺点，不利于临床与技工之间的传递，而且铸造成型后密合度低、固位差；应用硅橡胶制作存在不易操作，不易取全，造价高等缺陷，给临床工作带来很多麻烦。
三、发明内容：本实用新型的目的在于提供一种使用材料弹性好、经济方便，操作方法简单，制作的根管桩核模型易调整，精确、不易变形。其包括根管桩、核，根管桩插入根管内起固位作用，根管口的唇面颈部做成弧形凹面，制备成0.5～1mm的肩台，舌面颈部做成45°斜面，核是露在根管口外带冠的部分，与根管桩相连接。采用这样的结构可以为残根、冠修复提供良好的固位形和抗力形，防止根管桩核的松脱。
四、附图说明：附图为本实用新型的结构示意图。
五、具体实施例：按照桩冠修复的原则制备根面与根管，根管口的唇面颈部做成弧形凹面，制备成0.5～1mm的肩台，舌面颈部尽量做成45°斜面，清洗残渣。取经消毒处理的粘结成品塑胶牙底部的塑胶板，按照测试的根管长度和宽度，以技工钳钳取部分部分塑胶板，插入根管内调试，大小宽窄合适后备用。调制自凝树脂成糊状，用根管扩大针卷棉花浸湿单 体，将自凝树脂糊剂充满根管内，再将已备好的塑胶棒沾满自凝树脂糊剂轻轻插入根管内，待其初凝而又不硬时，轻轻拔出树脂桩检查，若桩完好，与管壁无粘连，再次插入根管就位，待其完全凝固后取出，以牙钻修整除去多余的部分，把根管桩1口外部分制备成桩核2，调试，至大小形状合适、摘戴自如、检查无误，完成根管桩核模型的制作。
