Description

烤瓷牙专用桩核
技术领域:
本实用新型涉及一种镶牙专用件,特别是一种烤瓷牙专用桩核,主要用于磨牙的修复。
背景技术:
目前在镶烤瓷牙时,均是用一个桩核固定在原有的牙根上,由于磨牙牙根数量多为1~3根,其桩核结构是:有一个与牙根相吻合的冠体,冠体与牙根接触面上设有与冠体成一体结构的插钉,插钉的方向是与牙根内的根管方向相同的,安装时将冠体置于牙根上并将插杆插入根管内,结合面均采用胶粘接。目前的这种固定方式不牢固,极容易脱落,修复率高,同时给患者带来麻烦和痛苦。
发明内容:
本实用新型的目的是提供一种安装方便、稳定牢固、不脱落的烤瓷牙专用桩核,以克服现有技术的不足。
本实用新型的技术解决方案是:一种烤瓷牙专用桩核,它包括冠体1,其特征在于;冠体1上设有孔6,与孔6相配有固位件2。
所述的冠体1上部设有凹5,固位件2为螺钉且上端设有档7。
本实用新型与现有技术相比具有安装方便、稳定牢固、不脱落的优点,从而导致修复率低减少了患者的麻烦和痛苦。
附图说明:
图1是本实用新型的安装结构示意图;
图2是冠体1的剖视示意图。
具体实施方式;
如图所示:1为冠体,在冠体1的上部加工有一个凹5,在凹5处向下加工有孔6,与孔6相配有端头接有档7的螺钉2,将螺钉2插入孔6内,档7刚好位于凹5内。孔6的方向与牙根4内的根管3方向一致。安装时先将冠体1置于处理好的牙根4上,再将螺钉2旋入根管3内,螺钉2与根管3的连接为自功方式,即可将冠体1固定在牙根4上,不致脱落。在冠体1上包有烤瓷牙套即可。所述的孔6、螺钉2的数量由牙根的数量而定。

Claims (2)
