What molar occlusion results after successfully treating an Angle's class II division I malocclusion and closing all spaces?

In the context of occlusion and orthodontic treatment, successful treatment of an Angle's Class II Division I malocclusion typically results in a full unit Class II molar relationship. Angle's classification is based on the relationship of the first molars, specifically how the mesiobuccal cusp of the maxillary first molar aligns with the buccal groove of the mandibular first molar.

When treating a Class II Division I malocclusion, the primary goal is often to achieve proper alignment and relationship of the molars. A full unit Class II occlusion means that the first molar on the upper arch is positioned more mesially in relation to the corresponding lower molar than in a typical Class I occlusion.

The treatment may involve not just aligning the molars, but also managing other dental discrepancies, which can allow the upper molars to have more overlap over the lower molars, thus creating a stable occlusion. Closing all spaces effectively secures this desired relationship after treatment, leading to a fully established Class II molar occlusion.

In contrast, options like ½ unit Class II and Class I would not accurately reflect the result of the treatment, as they suggest differing molar relationships that do not align with
