Abstract
本实用新型提供一种矫治单侧后牙反的下颌可摘式垫,属于医用器械领域。该垫,包括固位体(5)和基托(1),该基托(1)上设有后牙垫(6),所述后牙垫(6)的一侧为解剖式垫(2),另一侧为平面垫(3),所述平面垫(3)的外侧设有颊屏(4),该颊屏(4)通过颊屏连接体(7)与所述平面垫(3)相连;所述颊屏连接体为两根1.0mm的牙用不锈钢丝,其一端埋于基托(1),另一端埋于颊屏(4)内。本实用新型将功能性矫治与机械力矫治相结合,有效矫正单侧后牙反,解决传统方法引起的正常侧牙弓扩大,后期易复发等问题。
Description
技术领域
背景技术
发明内容
本实用新型提供一种矫治单侧后牙反的下颌可摘式垫,包括固位体5和基托1,该基托1上设有后牙垫6,所述后牙垫6的一侧为解剖式垫2,另一侧为平面垫3,所述平面垫3的外侧设有颊屏4,该颊屏4通过颊屏连接体7与所述平面垫3相连;所述颊屏连接体为两根1.0mm的牙用不锈钢丝,其一端埋于基托1,另一端埋于颊屏4内。
附图说明
具体实施方式
一种下颌可摘式垫,包括固位体5和基托1,该基托1上设有后牙垫6,正常侧设计解剖式垫2,将正常侧上下颌后牙锁结在一起,增强支抗,保持正常的咬合关系;反侧制作平面垫3,并略离开对牙,解除反侧的反锁结关系;所述平面垫3的外侧设有颊屏4,该颊屏4通过颊屏连接体7与所述平面垫3相连;颊屏连接体7是从反侧双尖牙区外展隙延伸出的2根1.0mm牙用不锈钢丝,一端包埋于下颌舌侧基托1,另一端包埋于颊屏4内以连接颊屏。其中所述解剖式垫的面部分制作出尖、沟、窝、嵴如同上颌牙齿的形态;所述平面垫的面部分为一平面,并略离开对牙,保证对 牙齿在咬合状态时不受其限制。
(a)取正中颌位咬合蜡;
(d)两根1.0mm牙用不锈钢丝弯制颊屏连接体横跨于反侧面,位于双尖牙区外展隙;
(e)用蜡将所述固位体及颊屏连接体固定于步骤(b)所得模型,并在所述模型表面涂分离剂;
(f)用自凝塑料涂塑,在正常侧制作解剖式垫、反侧制作平面垫及颊屏,垫高度以前牙咬合打开1-2mm为准;颊屏由上颌前庭沟底延伸至下颌前庭沟底,远中盖过最后一颗牙齿,近中达尖牙远中;颊屏的上颌部分与上齿槽间有2-3mm的空隙,可以消除颊肌对上颌侧方的压力有利于其扩展;下颌部分与下齿槽相贴合,颊肌压力可传达至下颌而抑制其生长。
Claims (1)
1.一种矫治单侧后牙反牙合的下颌可摘式牙合垫,包括固位体(5)和基托(1),该基托(1)上设有后牙牙合垫(6),其特征在于所述后牙牙合垫(6)的一侧为解剖式牙合垫(2),另一侧为平面牙合垫(3),所述平面牙合垫(3)的外侧设有颊屏(4),该颊屏(4)通过颊屏连接体(7)与所述平面牙合垫(3)相连;所述颊屏连接体为两根1.0mm的牙用不锈钢丝,其一端埋于基托(1),另一端埋于颊屏(4)内。
