Dentoskeletal Changes Associated With Herbst Appliance Therapy
MalocclusionAngle Class IIThe aim of the study is to perform a three-dimensional (3D) evaluation of the dentoskeletal changes in pubertal Class II malocclusion subjects treated with the Herbst appliance (HAG), in comparison with a Class II comparison group (CG). 3D virtual models generated from three time-point CBCTs (T0, baseline; T1, immediately after Herbst insertion; and T2, 8 months after) of 25 HAG patients will be evaluated. Virtual models obtained from 25 Class II malocclusion patients, in the same stage of biologic maturation and skeletal abnormality, but with no orthopedic treatment will be constructed for the CG subjects. These CG patients are under orthodontic treatment, but only with teeth alignment. Voxel based registration on the anterior cranial fossa will be used to assess maxillary and mandibular displacement/articular fossa remodeling; regional registration on the mandibular corpus will be performed to evaluate mandibular growth and mandibular dental changes; and regional registration on the anterior region of the maxilla will be performed to evaluate maxillary growth and maxillary dental changes.
Evaluation of a "Flash-free" Adhesive Resin for Orthodontic Bracket Bonding
MalocclusionThe purpose of this study is to compare bonding time, bond survival, amount of adhesive remaining on the tooth surface after bracket debonding, and time required for adhesive remnant cleanup between a new "flash-free" and a conventional adhesive resin for orthodontic bracket bonding.
Primer Aligner Study
MalocclusionTo demonstrate that a primer aligner product can achieve similar results to the currently marketed product.
Predictors Associated With Seeking Orthodontic Treatment, Compliance and Treatment Success
MalocclusionAngle Class IIAim: 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.
Personalized Titanium Plates vs CAD/CAM Surgical Splints in Maxillary Repositioning of Orthognathic...
MalocclusionAbnormalities1 moreThe purpose of this study is to determine whether personalized titanium plates can achieve better accuracy than CAD/CAM surgical splint in maxilla repositioning in orthognathic surgery, and evaluate the feasibility of this technique in clinical application.
Acceleration of Alignment of Crowded Lower Anterior Teeth
MalocclusionAngle Class I1 morePatients at the Orthodontic Department of 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, 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 two groups of patients with moderate crowding of the lower anterior teeth First group (Experimental): the patients in this group will be treated with orthodontic fixed appliances + surgery to the alveolus of the lower anterior teeth in order to induce remodeling of the bony structures and enhance orthodontic movement. Second group (Control): the patients in this group will be treated using fixed appliances with any acceleration method.
Comparison Between Two Methods in the Acceleration of the Retraction of Upper Canines
MalocclusionAngle Class II1 morePatients at the Orthodontic Department of 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, 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 flapless bone cutting by mechanical drills to evaluate the acceleration of the retraction of upper canines versus traditional bone cutting by piezo-surgery in comparison with a control group without bone cutting after extraction of upper first premolars in class II type I patients.
Evaluation of the Effect of Corticotomy and Low Level Laser Therapy on Orthodontic Tooth Movement...
Dental MalocclusionThe aim of the present study was to compare, a standard efficient technique in accelerating OTM as surgical corticotomy as a gold standard versus surgical corticotomy combined with LLLT in an attempt for further acceleration of OTM.
Predictability of Distalization and Derotation of the Carriere Motion Appliance.
Dental MalocclusionTo analyze the distalization or distal tooth displacement and derotation angle produced by Carriere Motion Appliance® (CMA) by using a repeatable and reproducible measurement digital technique.
