The utility model discloses a chunk of the lower jaw locking tooth, which includes a subcast crown, a subhorizontal palate bar, a splicing block, a main cross palate bar, a gelatine block and a main casting crown, a sub casting crown and a sub cross palate casting, the main cross palate and the main casting crown are cast in one, and the subcasting crown and the main casting crown are set in the upper and right side of the upper jaw, respectively, two. On the side of the tooth, the sub cross palate and the main cross palate are butted through the inserting block. The gel pressure is fixed on the inner surface of the main casting crown, the gel pressure is against the lower jaw and the mandibular tongue is tilted. The teeth in the main casting crown can also be helped by the adjacent two teeth, avoid the displacement of the front and back, and can be adjusted according to the size of the mouth. When the installation is installed, it is only necessary to install the casting crown and the main casting crown respectively, and then insert the inserted end into the corresponding blind jacks; and it may also be adjusted according to the course of treatment.

插块下颌锁合牙齿压低支架
本技术涉及在一种口腔正畸中使用的支架;具体是插块下颌锁合牙齿压低支架。
技术介绍
正畸治疗中,常见患者牙齿有锁合问题,所谓锁合就是指上下后牙的一种错合畸形,上颌个别后牙或多数后牙被锁结在下后牙的颊侧,或者是下颌个别后牙或多数后牙被锁结在上后牙的颊侧;通俗的讲,下颌和/或下郃的某几颗大牙长斜了。锁合分为两种类型,正锁合和反锁合,临床中常见的是正锁合,是指上后牙舌尖的斜面在下后牙颊尖颊斜面的颊侧,合面无咬合解除;个别后牙正锁合及单侧多数后牙的正锁合在临床较为多见;由于正锁合的锁结关系,影响下颌的侧向运动,会降低咀嚼效率,也可导致下颌有关肌肉的异常动力平衡,形成下颌骨左右发育不对称和颜面部对称畸形;还可导致颞下颌关节疾患。正锁合可有几下几种情况出现:1、上颌后牙颊倾,下颌后牙舌倾,即上下颌后牙的牙齿排列均有问题;2、上颌后牙颊倾,下颌后牙排列正常,即锁合的问题出现在上颌后牙;3、上颌后牙排列正常,下颌后牙明显舌倾,即锁合问题主要出现在下颌后牙,本申请主要针对第3种情况。从几何原理来说,长成倾斜的牙齿好比是直角三角形的斜长边,扶正后的牙齿好比是直 ...
