This retrospective study was undertaken to determine the presence of any features on a pretreatment lateral cephalogram that may be used to predict the success of improvement in the sagittal dental base relationship during functional appliance therapy in patients with a Class II skeletal pattern. Seventy-two patients judged to have been successfully treated with a functional appliance were sele...

1 modifies anatomy. The challenge of functional therapy is to maximize the genetic potential of growth and guide the growing face and developing dentition towards a pattern of optimal development. Functional appliance therapy aims to improve the functional relationship of dentofacial structures by eliminating unfavourable developmental factors and improving the muscle environment enveloping the...

OBJECTIVE The aim of this study is to evaluate dentoskeletal effects of Herbst and Twin Block (TB) appliance therapies in Skeletal Class II malocclusion. SUBJECTS AND METHODS Herbst group consisted of 11 girls and 9 boys (mean age = 12.74 ± 1.43 years), TB group comprised of 10 girls and 10 boys (mean age = 13.0 ± 1.32 years), and control group included 9 girls and 11 boys (mean age = 12.17 ±...

In growing patients. Class II malocclusion can be corrected by various modalities. Among all methods, functional appliances bring about better facial esthetics and functional harmony. Twin block is a most common among all functional appliances used to the correct skeletal discrepancy in growing individuals.1−4 A crowded dental arches necessities an additional prefunctional orthodontics to align...

the routine treatment for rotated maxillary incisor is a fi xed appliance, but in some instance the use of this method is impossible. in addition, in only limited cases of rotation, removable appliance is applicable. in this study, the use of a semi-removable appliance is presented, which has some benefi ts over the other methods. in this study, the corrections of about 70 -90° rotation of the ...

BACKGROUND/AIM Functional appliances can be used effectively in the treatment of skeletal Class II/1 malocclusions. The best treatment results are obtained during active period of facial growth when skeletal, as well as dentoalveolar, changes occur. In comparison with removable functional appliances, such as activator, that are effective only during adolescent period of growth, the Herbst fixed...

Introduction: Space maintenance in primary dentition in patients with early loss of several primary molars is a clinical challenge for pedodontists. In these cases, the conventional distal shoe appliance cannot be used and the efficacy of removable appliances is questionable. Thus, appliances with special designs providing increased patient acceptance and optimal efficacy are required in these ...

conclusions excellent esthetic and functional results achieved; total treatment duration was about 72 months. case presentation this is a case report about the successful orthodontic treatment of a patient with mild hemifacial microsomia (hfm), using a non-surgical orthopedic and orthodontic treatment approach. the aim of this approach was to make the best noninvasive modality to treat hfm. a 7...

Histochemical properties, muscle fiber cross-sectional area, muscle fiber length, and the oxidative capacity of masticatory muscles of female rhesus monkeys were assessed following alteration in functional length by an intraoral appliance or by detachment of the muscle. Experimental groups received the appliance only (A); the appliance and subsequent detachment of the masseter (AD); the applian...
