Soft tissue effects of Twin Block and Herbst appliances in patients with Class II division 1 mandibular retrognathy.
The aim of this study was to evaluate and compare the changes in soft tissue profile related to treatment with Twin Block and Herbst appliances. Sixty Class II, division 1, mandibular retrognathic patients were divided into three groups. Forty patients were randomly allocated to one of two functional appliance treatment groups. The first group comprised 11 girls and 9 boys (mean age= 12.74 ± 1....

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 ±...
متن کاملSoft tissue changes in patients with Class II Division 1 malocclusions treated using Twin Block appliances: finite-element scaling analysis.
To determine changes in soft tissue profile in patients with Class II division 1 malocclusions treated with Twin Block appliances (TBA), 99 pairs of lateral cephalographs were traced and 25 soft tissue landmarks digitized. Procrustes superimposition was used to generate average soft tissue profiles scaled to an equivalent size. Statistical differences between prepubertal, pre- and post-treatmen...
متن کاملBimaxillary morphometry of patients with class II division 1 malocclusion treated with twin block appliances.
To assess changes in bimaxillary morphology in patients with Class II division I malocclusion treated using Twin Block appliances (TBA), pre- and posttreatment lateral cephalographs of 100 patients seven to 16 years of age were compared. The patients were divided into four groups: (1) prepubertal boys (mean treatment time; 13.6+/-4.0 months), (2) adolescent boys (20.1+/-7.7 months), (3) prepube...
متن کاملComparison of Twin Block and Herbst Appliances in Treatment of Class II Malocclusion: a Systematic Review
In growing patients, it is possible to correct a second class skeletal mandibular retrusion with functional orthodontic appliances. We have viewed 1982-2016 PubMed articles to compare, in terms of compliance, timing, dental effects, and skeletal profilometric changes Twin block and Herbst appliances. The dental and skeletal effects are the same, but the Herbst unlike the Twin Block presents a r...
