Summary: | Key Clinical Message
Several approaches can correct pseudo‐Class III anterior crossbite. 2 × 4 appliance, compressed open‐coil springs, Class III elastics, etc. All cause either soft tissue lacerations, smile line flattening, or upper incisor overproclination. This paper describes a novel method to tip lower incisors into a normal overjet without compromising the upper dentition.
In pseudo‐class III cases, a “two by four” multibracketed appliance has been utilized to put the incisors into a typical overjet during transitional dentition. Compressing a rectangular super elastic archwire creates continuous force, but its length restricts activation and risks cheek impingement. Open‐coil springs on rigid archwires advance incisors labially, although a 4‐5 mm of wire distal to the molar tube may injure soft tissue. Reciprocally anchored Class III intermaxillary elastics restore anterior overjet through lower incisor lingual tipping and upper incisor proclination. Class III elastics extrude maxillary molars and mandibular incisors, rotating the dental occlusal plane counterclockwise and reducing maxillary incisor exposure and aesthetics. A unique method is reported in this report to tip the lower incisors back into normal overjet without affecting the upper dentition.
