Abstract
In modern orthodontic practice, a narrow upper jaw is often corrected using teeth-anchored expanders. As a result of skeletal expansion, dental orthodontic appliances have an adverse effect both on the teeth and on the supporting tissues. An analysis of the issues associated with dental fixation devices, as well as the results of combined orthodontic & surgical treatment with Surgically Assisted Rapid Palatal Expansion (SARPE), has allowed us to develop a palatal expander anchored on miniimplants. This method has been tested through the upper jaw expansion in patients in their post-pubertal period. The article offers a view at the changes in the skeletal and dental parameters during rapid maxillary expansion with the proposed expander. Skeletal expansion of the upper dentition in this case is achieved with minor changes in the lateral teeth inclination, thus allowing to minimize the risk of side effects typical for teeth-anchored expanders: root resorption, alveolar bone buccal thickness reduction, marginal bone reduction, and gum recession. The method proposed for upper jaw skeletal narrowing treatment with a palatal expander supported by mini-implants improves the upper airway.
