Filter by: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
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.
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.
The purpose of this study is to evaluate the efficacy of the Aerodentis System for orthodontic tooth movement in an open label, two-arms, non-inferiority clinical study. This open-label, two-arm study will follow 45 patients for up to fifteen months. Thirty participants will wear the Aerodentis device, and fifteen participants will wear Invisalign, a commonly used clear appliance. Patients will be assigned to participate in the treatment group using the Aerodentis device at home for 10 hours daily or in the control group using clear correctors for the duration of up to 15 months. Outcome assessments will be performed every 4 weeks. Assessments will include tooth movement and quality of life assessments.
OHRQoL assessment using OHIP-14 between sliding anterior retraction with self-ligating brackets and micro-osteoperforations for accelerated orthodontics in orthognathic surgery patients who were assigned for pre-molar extraction and decompensation
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
