Abstract
一种活动义齿,它包括齿体和卡环,其特征是在齿体和卡环之间设置了斜拉杆,本实用新型由于在齿体和卡环之间设置了斜拉杆,卡环套在后牙上,只有在义牙受力时,后牙才受到斜拉,平时不受力,具有美观大方,固位性好、不易脱落,不损伤天然牙体和牙周组织,不易造成内膜溃疡和牙周组织病变的优点。
Description
技术领域
本实用新型涉及镶牙技术领域,特别是一种活动义齿。
背景技术
目前、局部活动义齿的制做过程是先制作卡环、辅蜡,连接人工牙、烫蜡、埋合,等待石膏凝固后用热水烫泡,开合、填入基托粉并压紧,冷却、制成义齿,其工作原理是基托与牙床紧密配合,并依靠卡环的拉力使义齿固定,其缺点是容易暴露金属卡环、影响美观,固位差、易脱落,损伤天然牙体和牙齿粘膜,容易造成口腔内膜溃疡、引起牙周组织病变。
发明内容
本实用新型的目的是提供一种结构和制作简单,不易脱落,并能有效防止牙周组织病变的活动义齿。
本实用新型是这样实现的,它包括齿体和卡环,其特征是在齿体和卡环之间设置了斜拉杆。
本实用新型由于在齿体和卡环之间设置了斜拉杆,卡环套在后牙上,只有在义牙受力时,后牙才受到斜拉力的作用,平时不受力,具有美观大方,固位性好、不易脱落,不损伤天然牙体和牙周组织,不易造成内膜溃疡和牙周组织病变的优点。
附图说明
以下结合附图对本实用新型做进一步的描述;
图1是活动义齿的结构示意图。
具体实施方式
如图1所示,该活动义齿包括齿体1、卡环2和斜拉杆3,齿体1和卡环2之间通过斜拉杆3连接,使用时、将卡环2套在后牙上,只有当嚼食物时,后牙才受到义齿的斜拉力和轴心力的作用。
