View clinical trials related to Malocclusion, Angle Class III.
Filter by:The aim of the study is to compare a customized facemask for the treatment of Class III malocclusion in the prepubertal growing patient (patients between the ages of 5 and 12 years) versus a standard commercial facemask. Specifically, preference, pain, difficulty in sleeping, time of use, and possible complications for the two types of facemasks will be analyzed. This is a single-center, national, controlled, superiority, randomized, crossover, open-label study. Each patient will be treated with both the customized facemask and the standard commercial facemask. Each patient will wear one type of facemask for 2 months and the other type of facemask for the next 2 months. After 2 weeks and at the end of therapy with each of the facemask types, the patient, with the possible help of the parents, will have to answer a questionnaire about pain and difficulty sleeping and report any complications. In addition, after completing both phases (fourth month), the patient should indicate a preference for one of the two types of mask with which to complete therapy for an additional 6 months.
The aim of this randomized controlled trail is to compare the efficacy of an intraoral device (the Carriere® Motion 3D™ Class III Appliance) with the facial mask for the early treatemnt of Class III malocclusion. This is a monocentric, parallel, controlled trial with blinded examiner.
A clinical study to test the capability of the mini-screws inserted in the Mandibular buccal shelf area as an anchorage unit to distalize mandibular first molar for correction of mild to moderate Class III cases. The second aim was to detect if there is a difference in the amount of distalization in the presence of unerupted mandibular third molars, using the same technique.
Two groups with mandibular prognanthism indicated for mandibular setback by intraoral vertical ramus osteotomy . first group will fixed with maxillomandibular fixation and the second group will fixed by customized plate
the study is searching if there is a relationship between the blood groups and RH and the skeletal malocclusion using the skeletal class I as a control group
Class III malocclusions may originate in a retrognathic maxilla, a prognathic mandible or both. Young patients with class III malocclusion and maxillary hypoplasia are conventionally treated with a protraction facemask in order to stimulate forward growth of the upper jaw. This treatment option is often inducing unwanted side effects including mesial migration of the teeth in the upper jaw and clockwise rotation of the mandible. Because skeletal effects are often difficult to achieve with this approach, more pronounced class III malocclusions cannot be addressed by face mask therapy. These children cannot be treated during childhood and end up in major orthognathic surgery at full-grown age. To be able to treat also the more pronounced class III malocclusion and to minimize dentoalveolar compensations new treatment methods were developed which uses skeletal anchorage.
