FUNCTIONAL ORTHOPEDICS OF THE JAW: CLASS II MALOCCLUSION. ORTHOPEDIC INTERVENTION WITH BIONATOR AND ITS BENEFITS. A REVIEW

Abstract

Among existing malocclusions, Class II malocclusion has increased and become more recurrent, accounting for a significant proportion of patients seeking orthodontic treatment. Treatment can be conducted in different ways, with the two-stage approach being the most commonly used in cases requiring early intervention. It consists of the use of an orthopedic appliance, followed by a fixed appliance for occlusal refinement. The tooth-supported Bionator orthopedic appliance stimulates and accelerates mandibular growth through neuromuscular adaptation. The appliance acts by pushing the jaw forward, reestablishing a new mandibular position. The research addresses the effects and benefits provided by the use of Bionator, such as correction of mandibular retrognathism, correction of overjet, correction of space and lingual posture, as well as assistance in clearing the airways and stimulating nasal breathing.  In addition, the study discusses possible issues related to its use, such as the ideal age for intervention, adaptation, patient collaboration, and long-term stability. The results indicate that when diagnosed and performed at the right time, the appliance is highly effective for Class II correction, especially for patients with mandibular retrognathism, with benefits that can be seen in dental and aesthetic aspects.

OBJECTIVE: To present the Bionator appliance and the benefits it provides when diagnosed and performed early.
