Filter by:The aim of this prospective study was to compare between two different treatment modalities of class II division 2; to start treatment in upper arch first until adequate overjet is obtained or to start in the lower arch first with removable anterior bite plane in upper arch.
A randomised controlled clinical trial to compare the effectiveness of two functional appliances in the correction of a Class II malocclusion. (Class II malocclusions are where upper front teeth bite significantly further forward in relation to lower front teeth). Null hypothesis: There is no significant difference between the Button & bead and Twin-block appliances with regard to time taken to reduce the overjet
accelerated anterior teeth retraction with the help of microosteoperforation procedure and miniscrews.
Patients at the Orthodontic Department of University of Damascus Dental School will be examined and subjects who meet the inclusion criteria will be included. Then, initial diagnostic records (diagnostic gypsum models, internal and external oral photographs, as well as radiographic images) will be studied to ensure that the selection criteria are accurately matched. The aim of this study is to compare flapless bone cutting by mechanical drills to evaluate the acceleration of the retraction of upper canines versus traditional bone cutting by piezo-surgery in comparison with a control group without bone cutting after extraction of upper first premolars in class II type I patients.
Patients with class II malocclusion and retrognathic mandibles will be treated using functional appliances and asses the remodeling that is expected to occur in the temporomandibular joint (TMJ) using cone-beam computed tomography (CBCT) images and we will register mandibular movements using electronic axiograph ( a specific apparatus used to record jaw movements in three dimensions). There are three groups : 1. Activator Group 2. Twin block Group 3. Control Group with no treatment. Patients will be allocated to the three groups randomly. Data will be collected using three different approaches: - CBCT images before treatment and 12 months after treatment - Axiograph registrations before treatment and 12 months after treatment
The aim of this study is to evaluate the treatment effects of conventional twin block appliance versus modified twin block appliance in the treatment of patients in growing stage having skeletal class II division 1 with mandibular deficiency.
It is a prospective descriptive study to evaluate TMJ disc-condyle-fossa relationship using MRI scan following functional appliance therapy in skeletal Class II Division 2 malocclusion in adolescent females. All records, including MRI scans will be collected at three stages and will be traced for various angular and linear measurements to document the alterations within the condyle glenoid fossa complex 1. Stage- I (pre-treatment), 2. Stage- II (after pre-functional therapy) 3. Stage-III (After 6-8 months of functional appliance therapy that is after correction to Class I molar relation
Aim: to search for reasons for seeking orthodontic treatment, compliance during orthodontic treatment, drop-out from orthodontic treatment and success of orthodontic treatment. Methods: evaluation before, during and at the end of orthodontic treatment. Clinical and diagnostic evaluation of complexity before and at the end of orthodontic treatment, evaluation of awareness of treatment need, impact on social and psychological aspects, functional disturbances, impact of malocclusion on quality of life, social interaction, ability to perform daily activities.
To investigate each treatment modality in its "optimal" environment to avoid operator experience bias. Therefore we propose to operate out of three "specialist centres" with specific units providing one modality alone Which of the three orthodontic appliances does achieve best clinical progress, produce least discomfort to the patient, minimize the time taken for completion of treatment and maximize compliance.
the aim of this study is to document the changes brought about in the internal anatomic relationships of the TMJ complex , positional changes of glenoid fossa with respect to adjacent cranial structures after completion of fixed orthodontic treatment in adolescent males initially treated with removable functional appliances for skeletal class II, Angle's class II division 2 malocclusion
