Rapid maxillary expansion

Assessment of the dental and skeletal effects of fan-type rapid maxillary expansion screw and Hyrax screw on craniofacial structures

“…Similar to the posterior resistance offered by the circummaxillary sutures which allows the two halves of the maxilla to open in a V pattern,[15212223] the distal hinge in the fan-type screw offers a posterior resistance that allows a more “V-” shaped opening of the maxillary dental arch. The hinge therefore acts as an additional resistance to facilitate a more V-shaped opening.…”

Class III Subdivision Malocclusion With Unilateral Posterior Crossbite

“…Compared to banded type, bonded expander has got two potential advantages -occlusal force acting against the acrylic over the posterior teeth reduces the amount of extrusion and downward -backward rotation of the mandible, which is more important in long face patient. 4 In this case we selected bonded type for the above reason. Brust has shown that little tooth tipping is observed in bonded expander, presumably due to the rigid framework and bonding of the appliance to the posterior dentition.…”

“…Furthermore, the resistance of bony tissue and other soft tissues increases the tendency for relapse. [2][3][4][5] This paper discusses the management of transverse and anteroposterior problems with rapid palatal expansion and orthodontic fixed appliance respectively.…”

Cirugía del sueño: Definición de una especialidad emergente, propuesta de una clasificación anatomofuncional integral e indicaciones

“…Se han descrito varias modalidades: SARME/SARPE (surgically assisted rapid maxillary/palatal expansion) 66 , DOME (distraction osteogenesis maxillary expansion) 67 y EASE (endoscopically assisted surgical expansion) 68 . Los principios de esta técnica tradicionalmente han sido usados sin apoyo quirúrgico en niños (rapid maxillary expansion -RME-) 69 y recientemente también en adultos jóvenes (microimplant assisted rapid palatal expansion-MARPE-) 70 .…”
