Filter by:This experimental study will evaluate the effect of combined treatment with low-intensity pulsed ultrasound (LIPUS) and functional appliances (twin-block) on the correction of class II malocclusion, compared with the control group treated with functional appliances (twin-block) only. The study sample will consist of 40 patients with class II malocclusion. The sample will be allocated randomly into two groups: control group and experimental group. The functional appliance (twin-block) will be applied for all patients, while the low-intensity pulsed ultrasound (LIPUS) will be applied for the experimental group only. The skeleto-dental changes occurring after functional treatment will be assessed using cephalometric radiographs; pre and post- treatment changes for each group will be evaluated individually, and the two groups will be compared.
The investigators hypothesize that brief, daily application of HFA will increase the efficiency of clear aligner treatment by altering PDL metabolism without increasing pain or discomfort. The investigators will divide subjects into 5 groups changing clear aligners at different time intervals with or without HFA application for 5 minutes/day to assess the effect on: time intervals between aligners, cytokine activity, and pain perception.
This experimental study will evaluate the effect of combined treatment with low-level laser and functional appliances (twin-block) on the correction of Class II malocclusion, compared with the control group treated with functional appliances (twin-block) only. The study sample will consist of 40 patients with Class II malocclusion. The sample will be allocated randomly into two groups: a control group and an experimental group. Functional appliance (twin-block) will be applied for all patients. Low-level laser will be applied for the experimental group only. The skeleto-dental changes occurring after functional treatment will be assessed using cephalometric radiographs; pre- and post- treatment changes for each group will be evaluated individually.
The purpose of this study is to compare the effectiveness and efficiency of labial versus lingual biocreative therapy in achieving en masse retraction of the maxillary anterior teeth in subjects with class II malocclusion requiring upper first premolar extraction.
The aim of this study is to determine efficacy of OrthoPulse photobiomodulation on the rate of tooth movement during alignment for Subjects receiving fixed appliance orthodontic treatment.
This experimental study aims to evaluate the efficiency of the orthodontic removable traction appliance in the treatment of skeletal class III malocclusion. The study sample will consist of 44 patients with skeletal class III malocclusion. The sample will be allocated randomly into two groups: experimental group and control group. The dentoskeletal changes will be assessed by using lateral cephalometric radiographs before treatment and after obtaining 3mm positive overjet.
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
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.
Fixed orthodontic appliances in combination with intraoral elastics are a common and effective method use in the orthodontic correction of malocclusions. However, their success is largely dependent on the patient's compliance. Failure to wear the elastics as instructed will reduce efficacy of treatment, ultimately increasing treatment time and potentially producing imperfect alignment of teeth. The hypothesis tested is that daily electronic reminders via a mobile application can significantly increase patient compliance, thus effectively improving treatment outcomes.
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.
