Filter by:The purpose of this study is to demonstrate that changing aligners weekly provides similar results to changing aligners every two weeks.
To demonstrate that a primer aligner product can achieve similar results to the currently marketed product.
The purpose of this study is to provide evidence on the effectiveness, the efficiency and efficacy of Peizo-Corticission in accelerating orthodontic tooth movement and reducing orthodontic treatment time.
The purpose of this study is to determine if the Forsus Fatigue resistant Device appliance with direct skeletal mini plates anchorage is capable of achievement of skeletal mandibular effects while preventing the excessive proclination of the lower incisors at the end of the treatment when compared to the conventional Forsus Fatigue resistant Device appliance applied to the upper and lower dental arches in female patients with skeletal Class II malocclusion
The purpose of this study is determine the effect the Microosteoperforation (MOPs) using the miniscrew on the rate tooth movement. Moreover, measurement of the level of the pain and pain's interference, the level of satisfaction and comfort using this protocol. Finally root resorption associate with this technique will be evaluated.
The 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.
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.
The aim of this prospective, multicentric, randomized, open-label study is to assess the efficacy of the removable Twicare® as mandibular propulsive appliance in children aged from 7 to 12 years old in the course of their orthodontic treatment, showing its noninferiority with the removable Herbst. One untreated group will be included to control the internal validity of the study as recommend in noninferiority trials. Patients will have a follow-up every two months during 6 to 12 months as planned in routine care.
Thermoplastic devices are used in orthodontic treatment and consists of a series of nearly invisible, removable aligners. However, every device used in the mouth can change the buccal flora and increase the number of bacterias. This is a risk factor for enamel demineralization. The treatment can vary in time of use per day. The patient under orthodontic treatment has to use the device for 22 hour each day. When the period of retention comes, it is reduced to 8 hours. The investigators want to know if the concentration of bacterias in saliva and dental plaque will increase, and if the material can cause damage on gingiva.
The purpose of this research study is to assess the clinical effectiveness of a minimally invasive alveolar microperforation procedure to achieve accelerated tooth movement in patients undergoing orthodontic treatment for orthognathic surgery. "Accelerated tooth movement" means that Microperforation technique may help complete orthodontic treatment sooner than would be expected in conventional orthodontic treatment
