Active clinical trials for "Malocclusion"

This study is conducted to evaluate the effects of flapless laser corticotomy on the rate of canine retraction.

The study is aiming to evaluate the efficacy of Powerscope appliance in treatment of skeletal Class 2 malocclusion by three-dimensional image. Powerscope appliance is a hybrid fixed functional appliance used for treatment of Class II malocclusion with a retruded mandible.

Patients who have moderate crowding will be treated in this study. The efficacy of showing the predicted alignment of patient's teeth at the end of orthodontic treatment previously to treatment on their expectations from orthodontic treatment and their satisfaction with their teeth alignment will be assessed.

The purpose of this study is to examine the amount of tooth movement achieved over time between subjects undergoing aligner treatment using a pulsation device known as AcceleDent® Aura with those not using the device.

To test whether levels of OPG can be changed during orthodontic treatment. Alveolar bone samples will be collected from partially impacted third molars after orthodontic uprighting for different period of time in volunteers. In situ hybridization and immunohistochemistry analysis for OPG and RANKL will reveal their roles in this physiological process.

This study will assess the dentoskeletal effects of two types of maxillary expanders in orthodontic patients in the mixed dentition, from 7 to 11 years old. Half of participants will be treated using the expander with differential opening, while the other half will undergo rapid maxillary expansion using the fan-type expander. The null hypothesis is that there is no difference between dentoskeletal effects of the two protocols.

This study will evaluate the efficacy of rapid maxillary expansion (RME) and slow maxillary expansion (SME) in treating posterior crossbite using cone beam computed tomography. The study sample will consist of 32 patients who suffer from a skeletal posterior crossbite. The sample will be allocated randomly into two groups: RME group and SME group. The skeletal and dento-alveolar changes occurring after treatment will be assessed by using cone beam computed tomography(CBCT) radiographs.

We aim to assess the treatment outcomes following upper incisors retraction accelerated by corticotomy procedure. So, we intend to randomize orthodontic patients with class II division I malocclusion into two groups: experimental group and control group. Both groups will start orthodontic treatment. Once a 0.019*0.025-inch stainless steel wire is fully engaged to the brackets, 1st premolars will be extracted. Canines will be retracted in the conventional manner. Then, the actual evaluation period starts when the upper incisors are retracted using two different methods.

The objective of this study is to evaluate the efficacy of Clear Aligners to correct tooth malocclusions with the use of attachments and/or buttons, as determined by the amount of teeth movement and overall achievement goals of the treatment plan.

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
