We are pleased to share with our orthodontic colleagues the scientific article that Dr. Romina Vignolo Lobato and Dr. González Zamora have worked on, published in the latest issue of the journal of the Argentine Society of Orthodontics, on the treatment of Class II with aligners.

Abstract

Class II malocclusion is one of the most frequent skeletal disharmonies in the Caucasian population with a high prevalence of mandibular retrusion (approximately 80% of cases). It is a complex clinical situation that not only involves aesthetic problems, alterations in the sagittal plane, but is also associated with various conditions that require our attention, such as maxillary transverse relationship, mouth breathing, sleep apnoea, atypical swallowing, anomalies of the visual apparatus and bad oral habits or signs and symptoms of temporomandibular joint disorder (TMJ).

It is important to study and evaluate the optimal timing of patient treatment to maximise its effectiveness. Scientific evidence shows that the optimal time is the patient’s pre-pubertal growth spurt, a time that until now could be accessed with the different aligner protocols. The A6 protocol can be used from the primary dentition, which makes it possible to take advantage of the first growth peak between 5 and 7 years of age, when the 1st permanent molars erupt and a new correct occlusal plane can be created that favours mandibular movements and corrects the anteroposterior and vertical dynamics, opening up a new path in the early correction of malocclusions.
