Effects of mandibular protraction appliance associated to fixed appliance in adults.
OBJECTIVE This retrospective study aimed to conduct a cephalometric evaluation of the skeletal, dental and soft tissue effects resulting from treatment of adult patients presenting Class II malocclusion, performed with a Mandibular Protraction Appliance (MPA) combined with a fixed orthodontic appliance. METHODS The sample consisted of teleradiographs obtained before and after treatment of 9 a...
متن کاملMandibular Protraction Appliance Effects in Class II Malocclusion in Children, Adolescents and Young Adults.
The aim of this study was to evaluate the effects of the mandibular protraction appliance (MPA) for treating mild to moderate Class II malocclusion at different stages of dentofacial development. Lateral radiographs were evaluated before (T0) and at the end (T1) of orthodontic treatment with fixed appliance associated with MPA. Sixty-five consecutively treated patients were divided according to...
متن کاملMandibular molar protraction with temporary anchorage devices.
351 P of mandibular molars is challenging because of the high density of mandibular bone. Anterior dental anchorage is often inadequate to protract even a single first molar without reciprocal retraction of the incisors or movement of the dental midline. Furthermore, if the buccal and lingual cortical plates in the edentulous region have collapsed, safe and effective protraction may be impossib...
متن کاملFinite element analysis of mandibular molar protraction mechanics using miniscrews.
BACKGROUND/OBJECTIVES The aim of this study was to determine the most desirable force system to achieve molar protraction from an interdental miniscrew minimizing side-effects. Several iterations of force delivery were simulated through variations in the height of a miniscrew, length of a molar extension arm, and incorporation of a lingual force. MATERIALS/METHODS A three-dimensional mesh mod...
متن کاملTreatment of Mandibular Retrognathism with the Herbst Appliance
The first attempt at stimulating growth of the mandible in therapy of distal bite Class II/1 was initiated by Kingsley in 1877. The method described as “jumping the bite” is still applied today according to the principle of functional bimaxillary appliances such as for example activator, bionator, function regulator (1-3) and others, whereby the mandible is brought into the anterior position by...
