This invention refers to a MEASURING APPARATUS FOR THE PROGRAMMING AND WELDING OF ADJUSTABLE BRACKETS permitting the electrical spot welding with a great accuracy of the elements of an adjustable bracket, in this manner being able to adjust or to program the information that the orthodontist wants to incorporate in the bracket in regard to inclination, angulation and rotation. In order to achieve this aim I developed two attachments: THE POSITION MEASURING ACCESSORY and the WELDING ACCESSORY.THE POSITION MEASURING ACCESSORY has the function of recording or measuring accurately the dental position as for inclination, angulation and rotation on dental casts. This measurement is performed by means of a template system that allows the recording a tooth position in relation to its osseous basis and the occlusal plane.THE WELDING ACCESSORY has the innovation of allowing the accurate welding of the adjustable bracket elements (base and body), being able to adjust or program (in the three space planes) the information of inclination, angulation and rotation that the orthodontist wants to incorporate in the bracket by means of three fine graduation systems.
