An interdental immobilization device consists of a fixture of at least two components, a screw member (11), and a nut (17) or as a 3 or 4 part fixture employing a cone (16) with an aperture from base through apex so that the screw may slip therethrough, and the screw has a threaded helical shaft (13) which threadingly mates with the nut. The screw and the cone have the means for anchoring the screw to the cone. The cone is slipped onto the screw and anchored thereon; and, the screw is pushed through from inside the mouth, through the gum between adjacent teeth (50), and then engaged onto the threaded nut, whereby the fixture is secured between two adjacent teeth. Using a plurality of these two 3 or 4 part fixtures, staggered and spatially disposed along both upper and lower jaw, when they are interjoined with wire or elastic the lower jaw is effectively immobilized to the upper jaw. |
