Filter by:Patients at the Orthodontic Department of University of Damascus Dental School will be examined and subjects who meet the inclusion criteria will be admitted then the initial diagnostic records (diagnostic gypsum samples - 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 three groups of patients with severe crowding of the upper anterior teeth: - Group 1 : Patients will be treated using self-ligating brackets - Group 2 : Patients will be treated using self-ligating brackets associated with flapless corticotomy. - Group 3 : Patients will be treated using traditional brackets (i.e. brackets positioned on the labial surface of the teeth) At the end of leveling and aligning phase, we will compare the self-ligating brackets and traditional brackets ( the acceleration of teeth movement, dental and alveolar changes and other variables ) Also, there is an intention to study the effectiveness of using flapless corticotomy with the self-ligating brackets.
We will treat patients with class I malocclusion who have moderate crowding (4-6 mm) according to Little's irregularity index and asses the efficacy of low level laser therapy in accelerating orthodontic tooth movement . There is two groups : 1. treated with Low level laser therapy (LLLT) 2. treated traditionally without any irradiation Patients will be randomly allocated in any group and all data will be collected through photographs when leveling and alignment completed. Also pain levels will be assessed using numeric rating scale to compare between the two groups and if laser really can relief pain or not .
Patients who have severe crowding that require four premolars extraction will be treated in this study. The efficacy of the clear aligners and vestibular fixed appliances will be assessed. The treatment result of these two different methods will be explored using the Peer Assessment Rating (PAR) in two different times (T0: Before treatment, T1: After treatment) and the American Board of Orthodontics Objective Grading System (ABO-OGS) after treatment (T1). There are two groups: First group (Experimental): the patients in this group will be treated using clear aligners. Second group (Control): the patients in this group will be treated using fixed appliances.
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.
The purpose of this study is to assess the performance of the EXD-959 self-ligating ceramic bracket system using EXD 961 instruments in the treatment of orthodontic malocclusion. The information gained in this study and other studies will be used to evaluate the clinical performance of the bracket system during orthodontic treatment and to substantiate marketing claims for the bracket system, open/close instrument and de-bonding instrument.
The aim of the study is to investigate the effect of a pacifier (102 Medical Pacifier, Curaprox, Switzerland) on malocclusions like posterior crossbite, anterior open bite, larger overjet and tongue dysfunction in young children.
This study evaluates 2 Techniques of Surgically Assisted Rapid Maxillary Expansion (SARME) in the treatment of maxillary transverse deficiency. Half of participants will undergo an osteotomy between the maxillary central incisors, while the other half will undergo an osteotomy between the maxillary lateral incisors and canines (bilateral osteotomies).
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
The main objective of this study is to quantify the distal movement of maxillary central incisors and molars achieved with miniplate anchorage.
