Abstract

本实用新型涉及一种分段铸造支架式固定烤瓷桥,它由:牙齿弧形片状卡环、连接体、烤瓷冠固定桩、烤瓷冠、支托构成。两个牙齿弧形片状卡环的近远中分别设有连接体和烤瓷冠固定桩,两个烤瓷冠固定桩之间留有一定距离,两个牙齿弧形片状卡环上设有支托,烤瓷冠镶嵌在烤瓷冠固定桩内。该产品结构简单,使用方便,在不破坏牙齿情况下将烤瓷冠牢牢的固定在两牙齿中间,不对牙齿做任何磨削,牙齿弧形片状卡环与牙齿之间密贴为一体,不能进入任何腐蚀物,使用寿命长,固定效果好不脱落,价格低廉。

Description

分段铸造支架式固定烤瓷桥
技术领域:本实用新型涉及一种分段铸造支架式固定烤瓷桥。
背景技术:牙齿缺失后,必须得镶复义齿,要不然就会造成牙列的松动咬颌关系的紊乱,颌面部的变形,牙齿的歪斜,随着人民生活水平的提高,牙病患者对现有的活动义齿和固定义齿有了更高的要求,可摘活动义齿,由于咀嚼食物效率不高,卫生效果不好异物感大,易嵌塞食物残渣,取戴不方便,患者基本不喜欢使用。烤瓷取代了铸造支架义齿,虽然外表逼真美观、坚固耐磨,色泽近似于天然牙,生物相容性良好,不刺激口腔组织,易清洁,即能恢复牙齿的功能,又有美容的作用。边缘密合性大大优于传统的修复体,几乎没有异物感。但是烤瓷固定桥缺失一颗牙要做三颗牙来完成修复,不但多花两颗牙的钱,最重要的是为了镶复缺的一颗牙还要磨去健康牙齿部分牙釉质,牙齿没有了牙釉质牙齿也就没有了保护伞,随之而来的就是牙齿过敏、龋坏等牙齿疾病。在口腔修复学中能做到缺一颗镶一颗有种植牙和马里兰桥,但是种植牙齿价格昂贵,10年成功率低,一般的患者接受不了。马里兰桥虽然也能解决缺一颗镶一颗,价格也不高,但是它受到黏结材料的限制,使用寿命不会超过十年。
发明内容:本实用新型的目的在于克服上述缺点,提供一种分段铸造支架式固定烤瓷桥,它解决了现有的口腔镶复磨削健康牙齿及镶复牙齿使用寿命短等问题。本实用新型的目的是这样实现的,分段铸造支架式固定烤瓷桥由:牙齿弧形片状卡环、连接体、烤瓷冠固定桩、烤瓷冠、

支托构成。两个对称的牙齿弧形片状卡环的近远中分别设有连接体和烤瓷冠固定桩,两个烤瓷冠固定桩之间留有一定距离,两个牙齿弧形片状卡环上设有
