Abstract

Maxillary transverse deficiency is a widespread malocclusion present in all age groups, from primary to permanent dentition. If untreated on time, it can aggravate and progress to a more complex malocclusion which will further interfere with facial growth and development. Apart from the occlusal importance, the deficiency can cause serious respiratory problems due to associated consequent nasal constriction. In growing
patients, this condition can be easily treated with a conventional rapid palatal expansion. However, mature patients are frequently treated with a more invasive procedure such as surgically-assisted rapid palatal expansion. Recently, researches have demonstrated that it is possible to expand the maxilla in grown patients without performing osteotomies using microimplants. This novel technique is called Microimplant
Assisted Rapid Palatal Expansion (MARPE). MARPE technique was developed by Dr. Won Moon and colleagues at University of California – Los Angeles. In this appliance, four miniscrew positioned in the anterior and posterior part of the palate with bicortical engagement. MARPE produce even stress distribution, decreased the stress on the buccal plate of the anchor teeth, and reduced tipping of the anchor teeth. Thus,
MARPE may perform as an effective modality for the nonsurgical treatment of transverse maxillary deficiency in young adults. The aim of the present article is to describe the appliance designs, indications, contraindications, clinical aspects, activation schedule and miniscrew configuration, skeletal, and dental effects.
