    • A preformed mandible splint and a method of aligning and stabilizing a fractured mandible with such a splint is disclosed. The splint is configured to approximate the curvature of the lower teeth or the gingiva of the lower jaw. The curvature of an eight inch diameter sphere approaches the geometric curvature of the human teeth and gum, therefore, the similarly configured splint of the present invention is usable for almost any child or adult. The splint is approximately U-shaped, follows the human dental arcade, and has rows of holes or slots along its outer and inner perimeter. The splint is placed on the teeth or gingiva and wired through the holes or slots to the mandible thus correctly aligning the mandible. Fractures can then be screwed into place according to the curvature of the splint. This eliminates the need of wiring the patient's jaw shut as is presently done in current interdigitation techniques where even minute errors in mandibular repair results in flagrant morbidities in the patient. The U-shape allows the patient's tongue to freely move. Because the splint uniformly fits the population it can be preformed. The gumline follows the same curvature as the teeth, therefore the splint may be used on those without teeth by being placed directly on the gingiva.
    • 公开了一种预成形下颌夹板和使用这种夹板对准和稳定骨折下颌骨的方法。 夹板被构造成近似下颌的下齿或牙龈的曲率。 八英寸直径球体的曲率接近人牙齿和牙龈的几何曲率,因此,本发明类似配置的夹板几乎可用于任何儿童或成人。 夹板大致为U形,遵循人类牙科拱廊,沿其外周和内周具有一排孔或狭槽。 将夹板放置在牙齿或齿龈上,并通过孔或槽连接到下颌骨,从而正确对准下颌骨。 然后可以根据夹板的曲率将骨折拧入到位。 这消除了如目前在当前的交叉技术中所完成的关闭患者的下巴的需要,其中甚至在下颌修复中的微小错误导致患者的公然的病态。 U形允许患者的舌头自由移动。 因为夹板能够均匀地适合人口,因此可以预先形成。 牙龈跟牙齿相同的曲率,因此夹板可以直接放在牙龈上而不用牙齿。
