Molar distalization 2 by 2

The clinical cases of two young female patients presenting with a Class II dental malocclusion treated with the Invisalign technique in combination with Class II elastics are presented in this article. The first case showed a full dental Class II relationship, severe overjet, strong incisor proclination and an impacted maxillary canine. The second case displayed an asymmetric Class II canine and molar relationship. Both patients refused fixed appliances and chose aesthetic treatment options. Maxillary molar distalization was prescribed in the ClinCheck following a new protocol of 2 by 2 distalization. The new protocol proposed shortened treatment time and was effective to correct dental Class II malocclusion.
