When cephalometric features of Finns born around 1600 were compared with those born around 1930, the following differences were noted:3  Larger rami, increased posterior face heights, smaller gonial angles, more horizontally oriented mandibular bases, more palatally inclined upper incisors, smaller interincisal angles, and more pharyngeal spaces.

Bionator appliance was effective in generating differential growth between the jaws. (bvsalud.org)

The devices are available in a complete kit of four types of different first class arch shapes in relation to the type of cranial conformation, for an orthopedic functional action. (amcop.info)

The Balters Bionator is a functional appliance societal scope. (bvsalud.org)

The assumption is that a lack of masticatory function - and not genetics - might be considered a strong etiological factor in developing malocclusions in modern industrialized civilizations. (brightcopy.net)

The angles between mandibular stable structures and Go-Me (mandibular external rotation) and SN-GoMe (mandibular total rotation) increased by 0.6 ± 1.7 degrees and 0.9 ± 2.1 degrees, respectively. (edu.au)

This interaction can enhance, alleviate, camouflage and even make a malocclusion disappear. (sld.cu)
Different approaches to camouflage a Class III malocclusion have been suggested, ranging from extraction of premolars to en masse distalization of the entire lower arch. (pocketdentistry.com)

Franchi L, Baccetti T. Prediction of individual mandibular changes induced by functional jaws orthopedics followed by fixed appliances in class II patients. (ijcpd.com)

The modified Twin Block appliance is one of the most commonly used functional appliances due to its acceptability by the patient. (bhmedsoc.com)

Aim: To evaluate the influence of construction bite in the dentoskeletal changes induced by Klammt Appliance. (bvsalud.org)

He first introduced his functional orthopedic approach in 1966 at a meeting for European Orthodontic Society. (wikipedia.org)

The construction bite determines the amount of sagittal and vertical mandibular displacement of the appliance activation 1-4 . (bvsalud.org)
In both of the two groups analyzed, all the sagittal and vertical, angular and linear, skeletal measurements appear to be increased in a statistically significant way, except SNA angle and the distance Sna-Snp. (ijcpd.com)

Materials and Methods: The sample consisted of 96 skeletal Class III patients (42 women, 54 men) with a mean age of 25 years with standard deviation (SD) of 8.4. (jamilian.net)

9 The intermaxillary elastics and extra oral traction were no longer required for the functional appliance to function efficiently even in the rest position, the mandible will maintain a forward position. (bhmedsoc.com)
A passive self-ligation appliance, with infrazygomatic crest (IZC) bone screw anchorage, and Class III intermaxillary elastics were used to correct this severe malocclusion in only 10 months to a Cast-Radiograph Evaluation (CRE) score of 18. (iaoi.pro)

At the first visit, a Quad Helix * appliance was cemented to the upper first molars, the upper arch was bonded with preadjusted MBT ** .018" × .025" brackets, and a 2mm thermoformed clear retainer was fabricated for the lower arch, with cutouts in the canine and first premolar areas to allow attachment of the elastics.

Methods: The sample consisted of 17 children, with Class II malocclusion and initial mean age of 8.5 years. (bvsalud.org)
