8 Clinical Trials for Various Conditions
Misalignment of teeth and jaws (also called malocclusion) is a common life altering problem facing many individuals with Osteogenesis Imperfecta (OI). The presence of Dentinogenesis Imperfecta in teeth of OI individuals makes the use of conventional orthodontics in the form of braces very challenging. Clear aligners are newer form of orthodontic treatment and is less invasive than braces. Therefore, the aim of our study is to evaluate the efficiency and safety of using Invisalign clear aligners for orthodontic treatment in individuals with Osteogenesis Imperfecta. We seek individual with Osteogenesis Imperfecta, with mild to moderate malocclusion and no prior history of orthodontic treatment. This study will be held at three sites - McGill University, University of California Los Angeles and National Institute of Dental and Craniofacial research. This study will for the first time, help define guidelines for safe and efficient orthodontic treatment using clear aligners in individuals with Osteogenesis Imperfecta. If successful, this approach can rapidly be implemented into clinical practice, as the Invisalign system is readily available to orthodontists.
Osteogenesis imperfecta (OI) is a rare inherited disorder that causes bones to break easily. Individuals with osteogenesis imperfecta break bones often and may have other problems, including hearing loss and pain and difficulty getting around. People with moderate to severe OI may also be diagnosed with dentinogenesis imperfecta (DI). DI is characterized by grey or brown teeth that may chip and wear down and break easily. People with DI may also have skull and neck defects. These patients may have severe teeth misalignment resulting in clinically significant chewing problems. Teeth misalignment in OI is very hard to treat because of the quality and quantity of bone. The overall goal of this study is to improve dental health to improve the quality of life of people with OI.
The primary aim of this study is to evaluate the reported pain intensity following placement of Orthodontic separators on healthy volunteers aged 18-49 in relation to their recorded physical activity level. Hypothesis 1: The investigators hypothesize that participants with higher daily step counts and physical activity levels will report significantly less pain intensity from orthodontic separators than their less active peers following separator placement. Null hypothesis is that participants with higher daily step counts will report the same pain intensity from orthodontic separators than their less active peers following separator placement The secondary aim is to describe the course of pain, at 24 hr intervals, over the next seven days following separator placement. Hypothesis 2: The investigators hypothesize that more physically active participants will report ratings of zero pain intensity faster (sooner) than their less active peers throughout the one week study. Secondary null hypothesis is that more physically active participants will report ratings of zero pain intensity at the same rate as their less active peers throughout the one week study.
The purpose of this study is to compare the Full Fixed Preadjusted appliances (regular braces) when to the BRIUS system.
The decision on aligner changing is based on orthodontists' personal experience and common knowledge that an approximated time span for the aligner have exhausted its biological efficacy. However, a one size fits all approach is not always ideal, as an average determined time is not taken into account of a patient's individual biological response. The aligners could be progressed earlier than the determined time, or they may stay inactive for a while, waiting for the in-office visit. Dental MonitoringTM is the only available technology that provides 3D monitoring of teeth movement, reconstructs 3D digital models remotely, and auto-detect clinical situations by their patented AI algorithms. The investigators have reported high accuracy of DMTM to monitor the tooth movement in vitro. However, the efficacy of DMTM on orthodontic treatment and the accuracy of DMTM in the orthodontic patients has not been investigated yet. In this proposal, the investigators are implementing the Dental MonitoringTM application and 3D tracking of tooth movement powered by AI algorisms as a novel tool to customize aligner changing intervals. The ultimate goal is to reduce in-office visits and treatment duration while maintaining regular monitoring, thus not jeopardizing expected results. It is imperative to investigate the Teledentistry for its effectiveness, reliability, ease of use, patient satisfaction, and value on the overall health and oral health system, especially as a critical tool during public health emergency situations.
The investigators are studying how speech is effected by jaw and tooth position in jaw surgery patients. Eighty percent of our jaw surgery patients have speech pathologies, compared to five percent of the general population, but speech pathologists do not understand why. The investigators hypothesize that open bites and underbites prevent most patients from being able to pronounce words normally and surgical correction will lead to improvement in speech. Patients will be audio recorded speaking and patients' tongue gestures ultrasound recorded before and after their jaw surgeries to observe what changes occur in their speech and tongue movements.
A prospective study measuring changes in upper airway anatomy, quality of life measures, and polysomnographic parameters using a functional dental appliance (Homeoblock)
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.
