Comparative efficiency of Class II malocclusion treatment with the pendulum appliance or two maxillary premolar extractions and edgewire appliances

Abstract: The objective of this study was to compare, on study models and initial cephalograms, the efficiency of Class II malocclusion treatment with the pendulum appliance, and with two maxillary premolar extraction protocol. The sample consisted of 48 treated Class II malocclusion patients: group 1 comprised 22 patients (7 males, 15 females) treated with the pendulum appliance, with an initial mean age of 14.44 years and group 2, 26 patients (14 males, 12 females) treated with two maxillary premolar extractions at an… Show more

“…These interrelationships should be taken into account when comparing the initial weighted PAR indices of the different types of malocclusions. An average reduction in weighted PAR indices by more than 86% to values < 3.0 at the end of treatment represents a considerable improvement in percentages compared with other studies (78-86%) [6,18,21,30,36]. Likewise, evaluation of our treatment outcomes reveals an above-average improvement with a weighted PAR index of 2.9 [6,18,21,30,36].…”

Likewise, evaluation of our treatment outcomes reveals an above-average improvement with a weighted PAR index of 2.9 [6,18,21,30,36]. Only in those studies based on patient selection according to treatment outcome, in which only the most favorable outcomes were assessed, were the final values necessarily better [33].…”
