PREFORMED MANDIBULAR SPLINT

摘要

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-shaped 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.
