12 Clinical Trials for Various Conditions
The hypothesis of this project is that replacing the current 7-day wear protocol with a 3-day wear protocol, while integrating less tooth movement per aligner (reduce the amount of activation per aligner) may produce more consistent and continues orthodontic forces, therefore, increase the predictability, accuracy and outcomes achieved for various types of tooth movements and enhance the rate of tooth movement with the Invisalign system
Characterizing orthodontic tooth movements in real time by using photographic scans to monitor teeth movement. The photographic scans will also be compared to 3D model scans. Canine retraction over the course of 1 orthodontic visit will be measured.
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.
This open label study is designed to evaluate the ability of OrthoPulse™ to safely and effectively increase the rate of orthodontic tooth movement with fixed appliances.
Currently, orthodontic treatment typically lasts approximately 2 years. There are a number of advantages for reducing the duration of treatment, including reducing the potential risk of caries, root resorption and for minimizing patient "burn out" from prolonged treatment. While some evidence does exist that vibration may accelerate the speed of tooth movement, the biological mechanism is still unknown. Identification of specific factors involved in tooth movement that are further stimulated by vibration would help to understand the mechanisms involved as well as discover possible biologic targets which could be utilized or modified to maximize the benefits of vibration treatment. The purpose of this study is to identify novel biological factors that are expressed in patients undergoing orthodontic tooth movement in conjunction with vibration appliance therapy.
The purpose of this study is to examine the amount of tooth movement achieved over time between subjects undergoing aligner treatment using a pulsation device known as AcceleDent® Aura with those not using the device.
To gather data indicating whether or not the OrthoAccel device speeds tooth movement in people who use orthodontics (braces).
The study design of this research project involves orthodontic patients registered at the Harvard School of Dental Medicine who are deemed eligible to undergo orthodontic treatment and who have been provided with sufficient information to make informed consent to join the sleep study. These patients will be provided with the Medibyte sleep monitor and instructed on the proper manner in which it should be set up and worn for the one night study period. This process will be carried out twice throughout the course of the study, once before any orthodontic appliance has been cemented and once after the required amount of tooth movement has been attained with the orthodontic appliance still in place. The de-identified data from the Medibyte monitor will be downloaded using the Braebon software and analyzed.
The purpose of this research study is to assess the clinical effectiveness of the procedure of a minimally invasive alveolar microperforation procedure to achieve accelerated tooth movement in patients undergoing orthodontic treatment. "Accelerated tooth movement" means that using the PROPEL™ device may help complete your treatment with braces on one side of your mouth sooner than would be expected if the device were not to be used.
The aim of this study is to determine efficacy of OrthoPulse photobiomodulation on the rate of tooth movement during alignment for Subjects receiving fixed appliance orthodontic treatment.
The aim of the study is to determine if, and to what degree photobiomodulation treatment with OrthoPulse has an effect on the rate of tooth movement during alignment for patients receiving Invisalign orthodontic aligner treatment.
The AcceleDent® device has been introduced to the specialty of orthodontics in order to reduce treatment time. The theory behind AcceleDent® is that high frequency vibratory forces (30Hz) delivered to the teeth will stimulate the bone remodeling that is necessary for tooth movement to occur more quickly. Additionally, one claim of the AcceleDent® product is that it may reduce pain and discomfort during orthodontic treatment. This study will be a parallel group, triple-blind randomized clinical trial comparing two groups of subjects with 12 participants in each group. Subjects will be randomized to receive one of two vibrational units, which will differ in frequency and/or amplitude of vibration. The subjects will be asked to change their aligners every week instead of every 2 weeks, which is common with Invisalign.
