The Rick-A-Nator 2 can be used to effectively treat Class II skeletal malocclusions with normal maxillas, retrognathic mandibles, and deep overbites (where the AP correction needed is 4mm or less). Distal extensions support acrylic pads that cover the occlusal surface of the maxillary second molars. The purpose of these pads is to provide a "tripod effect" -- when the mandibular anteriors are contacting the incisal ramp, the lower second molars are also contacting the posterior acrylic pads.

This feature is extremely important -- especially if the patient exhibits signs and symptoms of TMJ dysfunction. The tripod effect generates the posterior support needed to prevent the condyles from moving superiorly (and causing the discs to become displaced). These pads also allow for the addition of posterior-vertical mechanics with inter-arch elastics -- without risk of rotating the condyle superiorly and posteriorly.
