This study will highlight the treatment of posterior crossbite using fixed appliances alongside a presentation of the types of fixed appliances utilized in the correction of posterior crossbites. Surgical processes are preferred because of their efficiency and effectiveness in correcting malocclusions. Generally, a combination of orthopedic and orthodontic tooth movements is required for the correction of the transverse discrepancy. it should be emphasized that correcting posterior crossbite at a young age, during early mixed dentition, is very important because the appliances and rapid maxillary expanders can be utilized to open mid-palatal suture when the suture can open.58enfixed appliancesposterior crossbiteDEENK Témalista::Orvostudomány::Fogorvostudomány
