Evaluation of treatment changes with rapid maxillary expansion using computed tomography scan: A comprehensive review
AUTHOR(S): Dr. Sudip Roy and Dr. Cheshta Walia
ABSTRACT:The aim of the study was to review in detail, the skeletal, dental and soft-tissue effects of Rapid Maxillary Expansion in young group of patients using Computed Tomographic Scan. The review is conducted through an electronic and manual searches which includes PubMed, Ovid, Cochrane, and Web of Science using the keywords. Searches includes the original studies which were conducted from the January 2000 to May 2020 amongst patients from 6 to 18 years using Hyrax, Haas-type and butterfly-type expanders. Based on the inclusion criteria, 23 relevant articles containing 298 patients were selected to evaluate changes related to skeletal, dental, soft-tissues and airway by assessing Computed Tomography scan. Significant effects have been observed at the mid-palatal suture due to the separation of two hemi-maxillae that led to an increase in the palatal volume, maxillary arch perimeter and correction of posterior crossbite. Changes were also recorded at the circum-maxillary sutures with maximum effects noted in internasal and nasomaxillary sutures. Other observations includes dental changes like buccal tipping of the maxillary posterior anchored teeth, increase in nasal and upper airway dimensions. Few side-effects of Rapid Maxillary Expansion includes recession of alveolar bone and dehiscence in cases of excessive dental tipping, dorsal hump on the nose with flattening of the nasal tip. Interpreting the outcomes with Computed Tomography scan strengthen the orthodontist’s precision in determining the 3-dimension effects with greater specificity. However, more number of Computed Tomography studies on soft-tissue changes and airway effects are required to understand comprehensive mechanics of the procedure.
