Filter by:The purpose is to fill knowledge gaps identified for orthodontic treatment using a novel study design that has not been implemented in the dental field or in orthodontics. The study design comprises an analysis, where outcomes of two techniques are assessed at several efficacy levels by different methods. Moreover, the project is designed to include a longtime follow-up that is unique in orthodontic treatment. The aim is to compare two techniques with buccally fixed appliance in a multicenter RCT of adolescents aged 12 to 17 years with crowding and tooth displacement. In the intervention group, patients will be treated with a self-ligating bracket system, and in the control group with a conventional bracket system. Outcomes will be assessed from the clinical, patients' and economic perspectives as: - Tooth alignment, function and adverse side effects - Patients' perception of pain, function and quality of life - Cost-effectiveness.
Patients who have severe crowding that requires four premolars extraction will be treated in this study. The efficacy and effectiveness of in-house clear aligners therapy compared with vestibular fixed appliances in the treatment of severe crowding malocclusion cases requiring the extraction of first premolars will be evaluated using Little's irregularity index (LII), Peer assessment rating index (PAR), and treatment duration. 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.
To evaluate the effect of the low power density 940nm diode laser in the total relief of dental crowding during the alignment phase and the perception of pain in patients who initiate orthodontic treatment.
The different types of brackets (e.g., self-ligating and conventional brackets), and the various acceleration methods (e.g., corticotomy) cause varying degrees of pain and discomfort. This study will assess pain, discomfort, and other patient-centered outcomes in adults with severe crowding on the upper jaw requiring two first premolars extraction. There are three groups: The first group (control group): the patients in this group will be treated using conventional brackets alone. The second group (Experimental group): the patients in this group will be treated using self-ligating brackets alone. The third group (Experimental group): the patients in this group will be treated using self-ligating brackets associated with flapless corticotomy.
Patients at the Orthodontic Department of the 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, and radiographic images) will be studied to ensure that the selection criteria are accurately matched. This study aims to compare two groups of patients with moderate crowding of the lower anterior teeth. Experimental group: the patients in this group will be treated with periodontally accelerated osteogenic orthodontics Control group: the patients in this group will be treated using fixed appliances without any acceleration method.
The duration of orthodontic treatment is one of the exacerbation causes of orthodontic pain. Several methods have been suggested to reduce the duration of orthodontic treatment classified to surgical and non-surgical methods. Researches used minimally invasive surgical methods like corticision, piezocesion, disicion, micro-osteoperforation, and piezopuncture indicated that most of these methods can accelerate dental movement by 20 - 40% without causing additional pain as a result of using those methods. Applying corticision on the lower anterior teeth using a surgical blade and a hammer may accelerate tooth alignment during orthodontic treatment. This study consists of two groups, patients will be randomly assigned to one of these two groups.
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.
Canine retraction after 1st premolar extracion into the extraction space is a routine treatment in orthodontics. Orthodontic patients requiring first premolar extraction, canine retraction and maximum anchorage were recruited for this randomized controlled trial. A search of the literature did not indicate the ideal frequency of elastomeric chain reactivation for optimum canine retraction. The study was approved by the ethical committee. The first premolars were extracted. Elastomeric chains were used to retract the canine distally into the 1st premolar space. The optimum reactivation interval was evaluated regarding the efficiency of treatment in terms of rate of canine retraction, canine tipping and rotation, root resorption and pain at the intervals of 2, 4, 6 and 8 weeks. Three dimensional imaging, as well as digital scanning were the methods for data collection.
Various malocclusions require the extraction of the first premolars and retraction of the canines with the need for maximum anchorage. If the canines are pulled into the extraction space using the molar teeth for support, unwanted tooth movement occurs. This study aims to evaluate the effect of temporary anchorage devices and power arms, which are auxiliary orthodontic appliances in reducing undesirable tooth movements.
The purpose of this study is to compare the Full Fixed Preadjusted appliances (regular braces) when to the BRIUS system.
