Filter by: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, micro-osteoperforation, and piezo-puncture 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 that could be treated without extraction will be treated in this study using either lingual or labial fixed orthodontic appliances. All patients will receive a cone-beam computed tomography (CBCT) scan in two different times (T0: before treatment, T1: after treatment). The dentoalveolar changes will be assessed.
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.
This experimental study will evaluate the effect of active and passive self-ligating brackets in treatment of crowding, compared with the control group of conventional brackets in class I malocclusion without extraction. The study sample will consist of 66 patients with 3-6mm crowding. The sample will be allocated randomly into two experimental groups, in addition to a control group. The brackets will be applied using indirect bonding method for all patients. The dentoalveolar changes occurring after leveling and alignment teeth will be assessed by using CBCT radiographs; pre and post- treatment changes for each group will be evaluated individually.
The aim of the present study was to compare the effectiveness of two alignment sequences with thermal activated archwires with different Af temperatures applied for the correction of mandibular anterior crowding
The hypothesis of this study that the Point-Of-Care Chemistry Test (POCT) may shorten Emergency Department (ED) length of stay (LOS).
