Official Title: Comparison of the Quantity of Distal Movement of the Upper Canine and Molar Using Class II Elastics With and Without Sliding Jig in a Period of 3 Months

Brief Summary: THE PURPOSE OF THE STUDY IS COMPARE THE QUANTITY OF DISTAL MOVEMENT OF THE UPPER CANINE AND MOLAR USING CLASS II ELASTICS WITH AND WITHOUT SLIDING JIG IN A PERIOD OF 3 MONTHS

Detailed Summary:

To achieve a Class I canine relationship at the end of the alignment and leveling phase, different intraoral devices have been used. These include intermaxillary class II elastics, which retract the upper and protract the lower arch, generating extrusive forces at the anchorage sites. Its upper distalizing action is exerted to the canine bracket and transmitted through the posterior teeth where the upper molar does not receive a direct force. The sliding jig is an auxiliary addition that exerts force to the molar by an elastic hanged in a jig between the lateral and the canine in class II; such mechanism decreases the vertical adverse effects of the elastics wearing while directing the distalizing force to the molar.

A randomized, unblinded, clinical trial comparing 30 units of analysis (hemi arches) in which were placed sliding jig or stand alone elastics were perform.

Current Primary Outcome: CT analysis for comparison of distal movement of upper canine and molar using class II elastics [ Time Frame: 3 months ]

CT were taken to compare the quantity of distal movement of the upper canine and molar using class II elastics alone.


Original Primary Outcome: Same as current

Current Secondary Outcome: CT analysis for comparison of distal movement of upper canine and molar using class II with Sliding Jig [ Time Frame: 3 months ]

CT were taken to compare the quantity of distal movement of the upper canine and molar using class II elastics with sliding jig


Original Secondary Outcome: Same as current
