Filter by: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.
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.
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.
Early orthodontic pain is usually caused by the insertion of elastomeric separators to the mesial and distal of the tooth to be banded in order to create adequate space for proper placement. Recent studies have demonstrated that the pain reaches its peak at 24 hours and then gradually decreases within 7 days The intensity of this pain is sometimes perceived as extremely high to cause a significant number of patients to discontinue the treatment. Nonsteroidal anti-inflammatory drugs, which block the prostaglandin synthesis through inhibiting the cyclooxygenase activity, is one of the most common methods used to manage the orthodontic pain. It has been reported that these drugs decrease the orthodontic tooth movement rate, in addition to many systemic side effects such as gastric and duodenal ulceration, coagulation disorders, congestive heart problems and allergic effect. The application of low-level laser therapy (LLLT) also reported being efficient in accelerating orthodontic tooth movement and in alleviating orthodontic pain without any apparent side effects. LLLT is thought to reduce the pain by increasing the local blood flow, inhibiting the secretion of inflammatory substances, inducing the release of neurotransmitters, altering the conduction and excitation of peripheral nerves and stimulating the endorphins release. On the other hand, literature review on the effectiveness of LLLT in alleviating orthodontic pain observed after elastomeric separator placement (ESP) exhibited conflicting results. While LLLT was found to be effective in some studies, the others refuted its effectiveness. When studies on alleviating orthodontic pain observed after ESP were reviewed, it was determined that the effects of many drugs and LLLT were evaluated subjectively by VAS. Furthermore, only in one study, the effects of ibuprofen and LLLT were compared using PGE2 levels in GCF and VAS. Based on that, this study was aimed to compare the effects of ibuprofen and LLLT in alleviating orthodontic pain observed after ESP through IL-1β and SP levels in GCF and VAS.
This experimental study will evaluate the effect of corticision on accelerating the leveling and alignment of lower crowded incisors compared with the control untreated group using cone beam computed tomography. The study sample will consist of 26 patients with less than 6 mm crowding. The sample will be allocated randomly into two experimental groups. The brackets and passive SS wire will be applied with radiographic metal guides between each tooth to allow for accurate corticision site 2 mm below the gingival papilla and to prevent tooth roots injury. The dentoalveolar changes occurring after leveling and alignment of lower anterior teeth will be evaluated using CBCT radiographs, Frequency, degree of root resorption, and the incidence of bone dehiscence will be assessed in relation to initial situation.
