Abstract:
1. Measuring apparatus for the programming and welding of adjustable brackets characterized by including a position measuring system for dental casts and a welding system for dental brackets; where the position measuring system allows the measurement in dental casts of the tooth inclination, angulation and rotation position, transmitting this information to the adjustable brackets by means of the welding system; with the position measuring system includes: a connector where the dental casts can be placed, a ball-and-socket mechanism to modify the dental cast inclination, orienting it in such a way that the occlusal plane is parallel to the horizontal plane; a lower support holding up an angular tridimensional measurement system that permits to measure the inclination, angulation and rotation position of the teeth in the dental cast by means of a measurement surface adjustable to the labial face of each tooth that is going to be measured; and the welding system for performing the joining of an adjustable bracket of two pieces weldable to each other; this welding system comprises: an angular tridimensional measuring system which allows to adjust or program the inclination, angulation and rotation information obtained by the measuring system in order to be transmitted to the adjustable bracket; a lower support including a first electrode; an upper tower comprising a second electrode; the first and second electrodes form an electrical spot welding circuit; that lower support includes an attachment for introducing one part of the adjustable bracket and the upper tower has a mean to support the other part, so that the coupling of the adjustable bracket parts is achieved in order to weld them.
