Variáveis relevantes no tratamento da má oclus？o de Classe II

results of orthodontic class ii malocclusion treatment can be influenced by inherent characteristics such as patient age, malocclusion severity and degree of compliance, or even by factors regarding the orthodontist's subjective preference such as the treatment protocol. basically, class ii treatment protocols involve nonextraction or extraction of two or four premolars. however, a greater treatment success rate can be expected with the extraction protocol of two maxillary premolars, regardless of the skeletal pattern or the amount of maxillomandibular anteroposterior discrepancy. according to this review, it was concluded that class ii malocclusion treatment results are strongly influenced by the treatment protocol, while skeletal characteristics do not seem to exert significant influence.
