An exostosis is a peripheral overgrowth of bone that is benign and has an undetermined cause. It may be an alveolar surface enlargement that is nodular, flat, or pedunculated. Torus palatinus (TP), torus mandibularis (TM), and alveolar bone exostoses (ABE) are the three anatomical terms for these lesions in the jaws, respectively. 1 Occasionally the same person may develop multiple exostoses. In young, dentate subjects, they may manifest as discrete, isolated bony growths on the facial alveolar bone or, less frequently, as multiple exostoses in the maxilla (torus palatinus) and mandible (mandibular tori) 2 (Table 1).Numerous authors have investigated the etiology of tori, but no consensus has emerged yet. Some of the speculated causes include genetics, environmental factors, masticatory hyperfunction, and continued growth. [3][4][5][6] Torus palatinus (TP) and torus mandibularis (TM) tori prevalence varies with sample population, ranging from 0.4% to 66.5% and 0.5% to 63.4%, respectively. Racial differences seem to be considerable with a significant

Several approaches can correct pseudo Class III anterior crossbite. 2x4 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

Alveolar bone exostoses (ABE) are benign localized convex outgrowths of buccal or lingual bone from the cortical plate, often known as buttress bone development. Our review and case series shows ABE following orthodontic treatment. If self-remission fails after orthodontic forces are removed, we have shown surgical methods to correct ABE

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.
