Class II, Div 1 – Central Incisor Protrusion and Anterior Spaces (SureSmile® Aligners)
Patient’s chief complaint(s): Central incisor protrusion and open bite. Patient refuses palatal arch expansion (MARPE) and extractions.
This teen patient presented with Class II molars and didn’t like his open bite and how protrusive his front teeth were. From his facial photos, it appeared his mandible was retrognathic or he lacked volume in his chin. Patient records also indicated there was a functional problem as there was no incisor guidance.
See how doctors are treating Class II cases with distalization primarily and without elastics in this SureSmile aligner case shared by Dr. Armando Dias da Silva. Dr. Dias da Silva is an orthodontist with a private practice in Porto, Portugal.
