Orthodontic bracket with variable prescription comprising two connectable components: the first, named bracket's body 25, composed by a base 1 with two medial hooks 8, an arch wire slot 2 and tie-wings 3; the second component named platform 4 has in one side a bonding surface 5 and on the opposite side two guide slots 6 and the medial elevation 7. This invention provides a design in which the base 1 of the bracket's body 25 is fitted by sliding in the guide slots 6 of platform 4. The mortise between the medial hooks 8 with the edges of medial elevation 7 provides the fixture between bracket's body 25 and the platform 4. In this way, the bracket's body 25 that has specifications such as thickness, height, torque and tip can be removed and replaced by another orthodontic prescription while the platform 4 remains fixed to the tooth surface.
