Vol. 14 – Number 56 – 2021 Case report Page 67-75 Bilateral posterior crossbite correction in a class III patient by dentoalveolar compensation – case report Josiane Goulart Silva¹ Francielen Prates Ferreira Barbosa² Rodrigo Romano da Silva³ Abstract The search for orthodontic treatment by adult patients has increased in the offices. Aesthetic demand is a contributing factor for this increase. When treating an adult patient, many types of occlusal problems can be found. As an example, we can mention the transverse deficiency of the maxilla. This clinical case is the compensatory treatment of a Pattern I patient with bilateral posterior crossbite, Class III molar relationship, upper arch atresia, and expansion of the lower arch. To perform the treatment self-ligating fixed appliance, Cooper NiTi wires with expanded diagram in the upper arch and conventional NiTi in the lower arch were used in conjunction with the bite lifters and the use of intermaxillary elastics (1/8 “) to uncross the bite. A satisfactory result was obtained by correcting the posterior crossbite ratio, obtaining a satisfactory Class I occlusion, improving the smile, overbite, and overjet within the standards, and resolving the patient’s complaint.
