Active clinical trials for "Overbite"

This study will collect data to try to assess which one of the two management options works better. The first option involves the use of the bite corrector first and then braces, while the second option involves the temporary addition of small support bone screws with the bite corrector later and then braces. Currently, it is not clearly known if there are important differences between the proposed management options. Such approaches are conventionally used in orthodontic practices. The information collected in this study will be used to compare the differences in the nature of the facial, teeth, and bone changes after the treatment. Questions about the experience while using the devices will be asked.

Patient with class ii division 1 malocclusion who have mild increased overjet will be treated in this study. The efficacy of clear aligners in the treatment of Class II division 1 Malocclusion Using Intermaxillary Elastics will be assessed. The skeletal, dental and soft tissues changes resulted by this intervention will be studied and compared with the results of Traditional treatment with fixed appliances. There are two group: a group of patients in which participants will be undergo to the clear aligners with class ii elastics. a group of patients in which participants will be undergo to the traditional fixed appliances with class ii elastics.

Effects of modified fixed twin block versus removable twin block on skeletal class 2 growing patients with mandibular deficiency: A Randomized Clinical Trial

Class II malocclusion with excessive overjet is one of the most common malocclusions among children and adolescents. The overall goal of the project is to analyze orthodontic treatment of Class II malocclusion with excessive overjet when the treatment is started in different ages and treated with removable and/or fixed appliance. Treatment initiated before the age of eleven is performed with a removable functional appliance, Headgear Activator (HGA). Treatment starting in early adolescence is performed with fixed orthodontic appliance (FA). The hypotheses are: Treatment with HGA at the age of nine or eleven is effective. No spontaneous correction of the malocclusion is expected in the untreated control group. Patient experience, treatment effect and cost-effectiveness are equivalent whether the treatment with HGA is initiated at the age of nine or eleven. Treatment results, patient experience and treatment- and cost-effectiveness are equivalent whether treatment is initiated early with HGA or initiated in early adolescence with FA. The treatment of Class II malocclusion with excessive overjet renders long-term treatment stability and patient satisfaction.

The goal of this clinical trial is to compare the pharyngeal airway changes after treatment with Myobrace and after treatment with Twinblock in developing skeletal Class II patients. The main question it aims to answer is: Is the efficacy of the twin-block Vs Myobrace appliances in the improvement of pharyngeal airway dimensions in adolescents having skeletal Class II malocclusion with retrognathic mandible utilizing sagittal pharyngeal airway area measurements.

Carriere Motion appliance (CMA) was designed to change a Class II molar relationship into a Class I relationship by distalizing the whole posterior maxillary segment by means of class II elastics and mandibular anchorage. To eliminate the adverse effects of CMA with class II elastics, we can use the CMA to distalize the maxillary posterior segment with intra-arch anchorage using infrazygomatic miniscrews. The aim of this study is to evaluate skeletaly anchored CMA for distalization of the maxillary buccal segment vs. conventionally anchored CMA by comparing skeletal and dental measurements obtained from lateral cephalometric radiographs obtained prior to treatment (T0) and immediately after correction of class II and remval of the appliance (T1).

Comparing the efficacy and performance of two conventionally anchored distalizers after modifying them to be skeletally anchored. En masse distalization is attempted by consolidating the posterior maxillary segment "first premolar to second molar" as one unit.

The aim of this randomized controlled clinical trial is to evaluate the dentoalveolar and skeletal treatment effects of the AMDA when used for distalization of the maxillary first molars in patients with Class II malocclusion in the permanent dentition.

There are situations where orthodontic treatment cannot provide long-term benefits. The proposed orthotropic theory proposes that environmental factors cause malocclusion and genes decide its pattern. The primary aim of this project is to increase the success, aesthetics and permanence of the treatment result by providing the best facial change of the pediatric patients in the MP3cap period, and that myofunctional exercises can be used in addition to orthodontic treatments during the treatment process of the patients.

Primary Objective Evaluating the effectiveness of canine retraction in terms of: rate of movement and rotation using 0.020-inch slot and dual-slot systems in comparison with the 0.022-inch slot system. Secondary Objectives Measuring the amount of molar anchorage loss during canine retraction between the different bracket slot appliances. Evaluation of alignment efficiency using different bracket slot appliances. Null Hypothesis There is insignificant difference in the effectiveness of canine retraction with different bracket slot size appliances. • Evaluation of the bracket slot and archwire dimensions precision
