DISTALIZATION OF MOLARS IN DENTAL CLASS II MALOCCLUSION WITH SLIDING HOOK MECHANICS

Abstract

OBJECTIVE. Two patients with filial bonds of 9 and 14 years old, female, in the consultation private; reason: presence of delay in the eruption of permanent teeth. In the clinical and radiological evaluation, case one, of 9 years, presents anomalous positions of parts 11 and 46. Case two, of 14 years: eruption anomalies of part 21, absence of second upper and lower left premolars. Both cases present Angle Class I occlusion, 4mm overhang and over 1/3 of the crown. The Demirjian methodology was used to quantify the stage of mineralization and maturity score. Finally, possible attributions to this cause of retention were discussed with a bibliographic review.
