Early Treatment for Class II Division 1 Malocclusion With Twicare® and Herbst Removable Appliances...

MalocclusionAngle Class II1 more

The aim of this prospective, multicentric, randomized, open-label study is to assess the efficacy of the removable Twicare® as mandibular propulsive appliance in children aged from 7 to 12 years old in the course of their orthodontic treatment, showing its noninferiority with the removable Herbst. One untreated group will be included to control the internal validity of the study as recommend in noninferiority trials. Patients will have a follow-up every two months during 6 to 12 months as planned in routine care.

Class II Division 1 Malocclusion

Twin-Block treatment and Dynamax treatment for Class II division 1 malocclusion do not have different effects with regards to treatment duration, the quality of dento-occlusal outcome, skeletal and soft tissue profile, patient discomfort and gingival health.

The Use of an Esthetic Twin Block for Patients With Mandibular Retrusion

Class II Malocclusion

This experimental study will evaluate the effect of an esthetic Twin-block appliance on the correction of class II malocclusion compared with the traditional Twin-block appliance. The study sample will consist of 50 patients with class II malocclusion. The sample will be allocated randomly into two groups: the control group and the experimental group. The traditional Twin-block appliance will be applied for the control group patients, while the esthetic Twin-block appliance will be applied for the experimental group patients. The dentoskeletal, soft tissue changes and esthetic and functional efficacy occurring after functional treatment will be assessed using cephalometric radiographs and profile photographs, pre and post-treatment, and a questionnaire. Changes for each group will be evaluated individually, and the two groups will be compared.

Effect of Low Level Laser Therapy on the Temporomandibular Joint During Treatment of Skeletal Class...

Malocclusion Class II

to evaluate effect of low-level laser therapy (LLLT) on mandibular condylar volume and position after treatment of Class II malocclusion with Twin Block (TB) functional therapy via cone beam computed tomography (CBCT). Materials and methods: Twenty eight growing patients, 14 boys and 14 girls ranged in age 9-12 years, were randomly divided into control group (mean initial age 10.64±1.36 years) and laser group (mean initial age 10.55 1.45 years). All patients treated with TB appliance where Gallium aluminum arsenide diode laser applied in one group weekly around TMJ region for 12 sessions in three months with set parameters: continuous 635 nm, 50 mW, 4.5J/cm2, 45 seconds/ point, total dose per side 11.25J. CBCT were obtained before and immediately after TB therapy, in addition to routine orthodontic records. Changes in TMJ and skeletal variables were analyzed and compared within and between both groups.

Mandibular Response After Maxillary Orthopedic Expansion in Class II Growing Subjects

MalocclusionAngle Class II1 more

the effectiveness of RME (Rapid Maxillary Expander) on the sagittal dental or skeletal parameters is still controversial because very little has been written regarding the behavior of antero-posterior mandibular changes in Class II growing subjects who underwent RME as the phase 1 treatment intervention. The reported significant occlusal improvement could be attributed to other reasons, ie, skeletal growth or the use of additional appliances during transition from mixed to permanent dentition. Moreover, the majority of the studies show some limits: they are not randomized, they are not prospective, and they have no control group or they use patients from growth studies as a source for the control group. The primary objective of the present investigation was to conduct a pilot randomized controlled trial (RCT) evaluating the changes in the antero-posterior mandibular position induced by bonded or banded RMEs compared with an untreated Class II control group
