Abstract

本实用新型公开了一种口腔科牙齿矫正演示模型,该演示模型包括硬质材料制作的上、下颌,在牙槽嵴处开有凹槽,凹槽内按人体正常牙齿排列装有全口人工牙,人工牙的根部与凹槽底壁之间通过万向节连接。门牙处凹槽的宽度略大于人工牙的厚度,以人工牙能够外翻45°度为准。凹槽内的剩余空间由弹性材料填充,在上、下颌的外表面包有一层乳胶罩,乳胶罩的侧开口与人工牙的牙冠根部连接。本实用新型的有益效果是:利用人工牙根部的万向节能够改变每个人工齿的排列状态,直观地展示多种牙齿畸形的实际状态。利用该模型还可以在其上面进行矫正方法演示,便于受培训的学员们从不同角度进行观看。

Description

一种口腔科牙齿矫正演示模型
技术领域
本实用新型涉及一种口腔科牙齿矫正演示模型。
背景技术
牙齿畸形是口腔科的一种常见病,在临床上通过专业的矫正治疗绝大多数患者都能够收到显著的效果。近年来许多医院都变成了当地医学院校的附属医院,医院里经常要承担一些专业课教学任务,在医院的口腔科也经常会接待一些在校实习生,由于牙齿矫正使用的器械较多,技术上也比较复杂,牙齿矫正器件都具有复杂的立体结构,这就给专业技术讲解造成了不便。
发明内容
本实用新型的发明目的在于提供一种口腔科牙齿矫正演示模型,该演示模型能够直观、形象地展示一些牙齿畸形状态及矫治器具的使用方法。
本实用新型的技术方案是:该牙齿矫正演示模型包括硬质材料制作的上、下颌,在牙槽嵴处开有凹槽,凹槽内按人体正常牙齿排列装有全口人工牙,人工牙的根部与凹槽底壁之间通过万向节连接。门牙处凹槽的宽度略大于人工牙的厚度,以人工牙能够外翻45°度为准。凹槽内的剩余空间由弹性材料填充,在上、下颌的外表面包有一层乳胶罩,乳胶罩的侧开口与人工牙的牙冠根部连接。
本实用新型的有益效果是:利用人工牙根部的万向节能够根据需要改变每个人工齿的排列状态,直观地展示多种牙齿畸形的实际状态。利用该模型还可以在其上面进行矫正方法演示,便于受培训的学员们从不同角度进行观看。
附图说明
以下结合附图和具体实施方式对本实用新型加以详细说明。
图1为本实用新型的结构示意图。
图中标号:
1、上、下颌  2、凹槽  3、人工牙  4、万向节  5、弹性材料
6、乳胶罩。
具体实施方式
如图1所示,该牙齿矫正演示模型包括硬质材料制作的上、下颌1,在牙槽嵴处开有凹槽2,凹槽2内按人体正常牙齿排列装有全口人工牙3,人工牙3的根部与凹槽2底壁之间通过万向节4连接。门牙处凹槽2的宽度略大于人工牙3的厚度,以人工牙3能够外翻45°度为准。凹槽2内的剩余空间由弹性材料5填充,在上、下颌1的外表面包有一层乳胶罩6,乳胶罩6的侧开口与人工牙3的牙冠根部连接。
