Filter by:The investigators are evaluating the effectiveness of custom-made 3D-printed ceramic (tooth-colored) brackets (braces) compared to conventional tooth-colored brackets (braces). Participants will be expected to come in for regularly scheduled appointments. They will be treated with tooth-colored braces and will need to come in every 4-6 weeks and will be randomly assigned to one of three groups. "Randomly" means by chance, like a coin toss. Neither participants nor the researchers may choose group assignments. Group 1 patients will have tooth-colored braces placed directly on each tooth by the clinician. Group 2 patients will have the braces placed on the teeth by using trays to fit them on. Group 3 patients will have customized 3D printed tooth-colored braces placed on their teeth, using trays to fit them on. If a participant is selected to be part of group 3, it may take up to two additional weeks for these 3D brackets to be printed and shipped and so this might delay treatment onset. Information on gender, age, and medical history of participants will also be obtained from the electronic health record.
The long time needed for orthodontic treatment is considered one of the biggest obstacles that make patients refuse to undergo orthodontic treatment. It also has many disadvantages including higher caries rates, gingivitis, and root resorption. Therefore, the purpose of this study is to evaluate the efficiency of two new noninvasive methods (Low-Level Laser Therapy and Corticopuncture) in accelerating orthodontic tooth movement for the implant supported En-Masse retraction of the six maxillary anterior teeth.
Dental occlusion is the reciprocal confrontation of the two dental arches. The child has two set of temporary and permanent teeth and passes through different stages of dentition during which dental, skeletal or functional abnormalities may appear. Dental malocclusion is defined as an incorrect position of the teeth in the bone base, as well as the incoordination of the teeth of the opposite arches or the displacement of the maxillary and mandibular skeletal bases. When a malocclusion is detected during clinical examination, patients are referred to an orthodontic specialist. The interception in orthodontics is carried out during a growing period; it consists of correcting or reducing malocclusions in evolution and eliminating the functional causes to prevent aggravation of skeletal and dental abnormalities. An epidemiological study conducted in France on 789 children showed that 37.4% had at least one type of dental malocclusion. In 2010, a study of 5988 French children showed that 14% of them had received orthodontic treatment. These studies reveal a discrepancy between treatment needs and treatments conducted. In addition, certain dental malocclusions and skeletal disorders, such as lateral and anterior crossbite, require early orthodontic treatment in order to avoid aggravation of the occlusion disorder and induction of craniofacial growth disorders. Unfortunately these discrepancies are not always detected by the caregivers (pediatrician, general dentist, pediatric dentist). A schematic representation of malocclusions in temporary and mixed dentition requiring orthodontic interception has been developed by the investigator's team to provide a simple visual means of identifying these dental and skeletal disorders in order to improve early screening by practitioners involved in the mandatory medical follow-up of children.
The aim of this study is to evaluate the levels of pain, discomfort and acceptance between two treatment modalities of Class III correction of growing patients in the late mixed dentition period.
The 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.
The aim of this study is to compare en masse (EM) and two-step anterior teeth retraction (TSR) evaluated by means of three-dimensional images superimposition. Thirty-two adult patients with bimaxillary protrusion planed for treatment with four first premolar extractions will be enrolled. All patients will be randomly allocated in a 1:1 ratio to either EM (n=16) group or the TSR (n=16) group. Cone bean computed tomography will be taken before and after anterior retraction. A blind observer will construct separate 3D models for maxillary and mandibular surfaces using the anterior cranial fossa to register models of before and after space closing. Quantitative assessment of posterior anchorage loss and amount of anterior teeth retraction are the main outcomes. The secondary outcomes are the inclination of the molars, canines and incisors.
The study product is a Cold Ablation Robot-guided Laser Osteotome (CARLO®) robotic surgery device. It is a device that removes hard tissue such as bone by means laser ablation - it is therefore an alternative to Piezo-Electric osteotomes and/or oscillating saws or other mechanical instruments for bone cutting. In this study, the CARLO device is integrated with a computer-assisted pre-operative planning and intra-operative navigation, and will be used for Patients requiring an orthognathic procedure with a mid-face osteotomy, for whom a procedure plan is defined based on preoperative imaging.
The main purpose is to compare overall alignment time (OAT) in days in alleviating mandibular incisors crowding between control group and MOPs group.Furthermore, to investigate the presence of volumetric root resorption from CBCT, gingival recession and formation of black triangle post lower labial segment alignment between micro-osteoperforations group and control group.
Importance and justification The importance of carrying out this study is to verify the electrical activity generated by the masticatory muscles to be able to have clarity of their performance in the development of orthopedic treatment, thus complementing the diagnosis to achieve a more successful treatment with myofunctional device SN1 in Class II malocclusions. In addition, with the results of this study, treatment prediction criteria are provided to the clinician, depending on the thickness of the muscle, more specific equipment will be chosen to solve the malocclusion and prognosis when using the SN1 myofunctional device in class II malocclusions. Additionally, it has academic utility, since there is little scientific evidence about myofunctional SN1 device and its impact on masticatory muscles, thus opening the door to a line of research where this study can be used as a basis for future orthopedic clinical research. in UNICIEO. Added to this and according to the results, the knowledge about the SN1 will be updated, thus providing evidence for the teaching of orthopedics for the students; and also a measurement protocol with electromyography for children will be provided Overall objective To evaluate the electrical activity of the masseter and temporal muscles in patients from 7 to 12 years of age, with skeletal class II who are under treatment with myofunctional apparatus (Sn1), in the UNICIEO orthopedics clinic by means of kinesiological electromyography compare with a control group without use of the device Specific objectives - Determine the activity of the masseter and temporal muscles of patients at rest (without functional orthopedic apparatus) in the two study groups. - To determine the activity of the masseter and temporal muscles of the patients after the use of functional orthopedic equipment (Sn1), after six months of treatment and in the control group without treatment.
This study will assess the dentoalveolar effects and impact on quality of life of two types of maxillary expanders in orthodontic patients with permanent dentition, from 12 to 16 years old. Half of participants will be treated using the Hyrax expander, while the other half will use the mini Hyrax expander. The null hypothesis is that there is no difference between dentoalveolar effects and impact on quality of life of the two protocols.
