Mini-Screw Assisted Rapid Palatal Expansion - A New Horizon to Correct Transverse Dimensions

Rapid Palatal Expansion (RPE) is the treatment of choice to correct the maxillary transverse deficiency (MTD) [1]. However, expansion of maxilla in post pubertal patients might notbe feasible and might result in unwanted side effects such as limited skeletal movements, dentoalveolar tipping, root resorption, detrimental periodontal consequences, and lack of long-term stability [1]. Surgically Assisted Rapid Palatal Expansion (SARPE) was an invasive method, and the morbidity, risks and cost related to surgical treatment might discourage many adult patients. The use of Mini-screw Assisted Rapid Palatal Expansion (MARPE) appliance, being a minimal invasive procedure, is gaining popularity in treatment ofmaxillary transverse deficiency (MTD) in young adolescent patients. This article reviews about the MARPE appliance design, activation protocol and post treatment outcomes.
