ABSTRACT:
A method and apparatus are disclosed for saving an exarticulated tooth. The tooth is grasped by its crown, so as not to harm the periodontal membrane. In one embodiment, the tooth is placed in a net which is attached to a basket. The net and basket are immersed in a modified saline solution which preserves the cells of the periodontal membrane. The solution is held in a container which accommodates the net and basket. The container is closed, and the tooth and patient are taken to a dentist. The dentist removes the lid of the container, and lays the lid on a table or other surface, so that the sponge faces upward. The dentist then lifts the basket, with the tooth, out of the solution, and inverts the net so that the tooth falls out onto the sponge. The dentist then grasps the tooth with a forceps and reimplants it in the patient's mouth. In other embodiments, the net is omitted, and is replaced by padding in the container which protecgts the tooth. In still another embodiment, there is a net but no basket, and the net remains within the container. In another embodiment, the solution is stored in a bag which is held within the container lid. A knife edge punctures the bag when the lid is unscrewed. In yet another embodiment, the tooth is stored in a pouch of water-impermeable material and removed immediately before reimplantation.
