Three-dimensional skeletal mandibular changes associated with Herbst appliance treatment

Treatment 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...

Dental and skeletal changes in patients with mandibular retrognathism following treatment with Herbst and pre-adjusted fixed appliance

OBJECTIVE To assess the dentoskeletal changes observed in treatment of Class II, division 1 malocclusion patients with mandibular retrognathism. Treatment was performed with the Herbst orthopedic appliance during 13 months (phase I) and pre-adjusted orthodontic fixed appliance (phase II). METHODS Lateral cephalograms of 17 adolescents were taken in phase I onset (T1) and completion (T2); in t...

Meta-analysis of skeletal mandibular changes during Frankel appliance treatment.

The purpose of this study was to perform a meta-analysis of articles to verify the mandibular changes produced by the Fränkel-2 (FR-2) appliance during the treatment of growing patients with Class II malocclusions when compared with untreated growing Class II subjects. The literature published from January 1966 to January 2009 was reviewed with search engines. A quality analysis was performed. ...

Complications during Herbst appliance treatment.

Neuromuscular and skeletal adaptations following mandibular forward positioning induced by the Herbst appliance.

The purpose of this study was to examine neuromuscular and skeletal adaptations to changes in sagittal jaw relationships induced by the Herbst appliance. Six patients (age, 9 years and 5 months to 11 years and 2 months) with Angle Class II, division 1 malocclusions were studied longitudinally. The structural changes were determined by analyzing serial lateral cephalograms. Electromyographic rec...
