Filter by: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 aim of this study is to compare the efficacy and safety of drug therapy, tonsillar adenoidectomy only, orthodontic treatment only and tonsillar adenoidectomy plus orthodontic treatment in children with obstructive sleep apnea hypopnea syndrome (OSAHS) and malocclusion. In this study, we hope to improve children's OSAH in function, three-dimensional shape and subjective and objective symptoms of sleep breathing through tonsillar adenoidectomy plus orthodontic treatment.
To investigate each treatment modality in its "optimal" environment to avoid operator experience bias. Therefore we propose to operate out of three "specialist centres" with specific units providing one modality alone Which of the three orthodontic appliances does achieve best clinical progress, produce least discomfort to the patient, minimize the time taken for completion of treatment and maximize compliance.
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
In dentistry, Peer Assessment Rating (PAR) is an objective way of quantifying how maligned a patient's teeth are by scoring orthodontic study models. It can also be used to assess treatment outcome by comparing pre- and post-treatment scores. Traditionally, PAR scoring is performed manually on plaster casts by a trained and calibrated individual. The plaster casts consume considerable amounts of storage space and the process of manual scoring can be time consuming and expensive. The recent decades have seen a rise in popularity of intra oral scanners in dentistry to produce digital study models. These obviate the need for physical storage space and a software can be used to calculate PAR scores more conveniently and at a faster speed. A review of the current literature showed that the CS 3600 intra oral scanner by Carestream Dental demonstrated acceptable accuracy for clinical use. In this study, patients will receive the usual impressions and their moulds will be PAR scored manually (usual care pathway). In addition, they will also receive intra oral scans with Carestream 3600 and the digital models will be scored by a computer. Manual and digital scores will be compared and analysed for any significant discrepancies.
Twenty patients need therapeutic extraction of the maxillary first premolars with subsequent retraction of the maxillary canines, will be divided randomly into two groups, and will randomly assigned to one side of the maxillary arch at the first premolar region, and the other side served as the control. Canine retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side. Soldered transpalatal arch will be used as an anchor unit. The dento-alveolar changes will be assessed immediately before retraction and after 6 months using CBCT.

Pre- and post distalization dental casts will be evaluated to study rate of canine distalization, over a follow-up period until a Class I canine relationship will be achieved. The levels of Pain and discomfort will be monitored using a questionnaire with a VAS scale administered three times during the first day after prf injection.
Purpose: This project aims to study the effects of wire dimension and ligation method (bracket type) on the first stage of orthodontic treatment using 3D imaging. Participants: Up to 80 patients at UNC School of Dentistry or Selden Orthodontics between the ages of 10 and 45, inclusive, who have been previously diagnosed with malocclusion requiring orthodontic treatment (braces) and are otherwise healthy. Procedures (methods): Subjects receiving standard of care (SOC) orthodontic treatment will be randomized to one of two commonly used orthodontic archwires (.014" or .016" diameter). Subjects will be further subdivided for analysis based on the type of bracket (twin or self-ligating) that their clinician uses in their treatment. We will review the 3D digital images of each subject's dentition recorded as part of SOC at the 0-, 6- and 12-week visits. We will retrieve the archwires when they are removed per SOC by the clinician at the 12-week time point.
