Personalized orthodontic bracket height in relation to marginal ridges.

: Correct bracket placement should level both the marginal ridges and the occlusional plane. The authors describe the laboratory and clinical procedures of placing brackets in relation to the marginal ridge. The ray set is a device that allows each tooth to be dealt with an individual unit, virtually isolating it from the rest of the arch and analyzing its position in a 3-dimensional control system that determines the first-, second-, and third-order values, which the clinician needs or which must be written into the slots. The ray set makes it possible to develop and simplify bracket placement methods without a preliminary set-up, while taking an accurate reading of the marginal ridge to establish the height of slots. This procedure can be used with all multibracket techniques (vestibular and lingual) aiming to properly level the occlusal plane, thereby ensuring the correct final occlusion.
