Effectiveness Of Rapid Palatal Expansion (RPE) In Class II Maloclusion and The Relationship With Muscle Contraction In Childhood Growth: Systematic Review

Abstract

Background: In general, patients with Class II malocclusion are often associated with a narrow transverse dimension. The shape of the narrowed jaw space can cause various problems such as crowding, jaw mismatch, protrusion of incisors. Given this, the use of Rapid Maxillary Expansion or Rapid Palatal Expansion is a treatment option that has been the choice for decades. Objective: To systematically review the benefits of using RPE in the improvement of malocclusion in child development. This device is used to correct maxillary constriction and posterior crossbite. Methods: From four database sources PubMed, GoogleScholar, Wiley and Cochrane from 2016 to 2021. Thedatabase search process used the keywords "Rapid Palatal Expansion" "Rapid Maxillary Expansion" "Class II", from full journals published in less than 5years. Results: After eliminating duplicated articles, the abstract title of each article was analyzed from 136 articles which were excluded a total of 123 articles. Thetext of the article is complete and meets the eligibility as many as 13 articles. Conclusion: Rapid Palatal Expansion is effective in correcting class II malocclusion in child development.
