Comparison of two maxillary protraction protocols: tooth-borne versus bone-anchored protraction facemask treatment
BACKGROUND Protraction facemask has been advocated for treatment of class III malocclusion with maxillary deficiency. Studies using tooth-borne rapid palatal expansion (RPE) appliance as anchorage have experienced side effects such as forward movement of the maxillary molars, excessive proclination of the maxillary incisors, and an increase in lower face height. A new Hybrid Hyrax bone-anchored...
متن کاملDigital evaluation of nasal changes induced by rapid maxillary expansion with different anchorage and appliance design
BACKGROUND Scientific evidence showed that rapid maxillary expansion (RME) affects naso-maxillary complex, increasing nasal width and volume. This study aimed to evaluate nasal changes induced by rapid maxillary expansion with different anchorage and appliance design by using low dose and cone beam computed tomography. METHODS A total of 44 patients (20 males, mean age 8y 8 m ± 1y 2 m; 24 fem...
متن کاملApplication and effectiveness of a mini-implant- and tooth-borne rapid palatal expansion device: the hybrid hyrax.
AIM Rapid palatal expansion (RPE) is used for treatment of skeletal crossbites. It may be combined with a face mask if the maxilla is to be protracted. Conventional tooth-borne appliances rely on an almost complete dentition to transmit the relatively high forces to the bony structures of the maxilla and midface. In most situations, tooth-borne appliances produce adverse effects such as buccal ...
متن کاملThe Hybrid Hyrax Distalizer, a new all-in-one appliance for rapid palatal expansion, early class III treatment and upper molar distalization.
Growing class III patients with maxillary deficiency may be treated with a maxillary protraction facemask. Because the force generated by this appliance is applied to the teeth, the inevitable mesial migration of the dentition can result in anterior crowding, incisor proclination and a possible need for subsequent extraction therapy. The Hybrid Hyrax appliance, anchored on mini-implants in the ...
متن کاملHYRAX versus HAAS EXPANSION APPLIANCES
The present study evaluated rapid maxillary expansion (RME) periodontal effects by means of computed tomography (CT), comparing the tooth-tissue-borne and the tooth-borne expanders. The sample comprised 8 girls aged between 11 to 14 years, presenting with Class I or II malocclusions with unilateral or bilateral posterior crossbite. The sample was randomly divided into two treatment groups (Haas...
