Filter by:The goal of this clinical trial is to to evaluate and compare the skeletal and dental changes of bone supported Fast Back and bone supported modified Leaf Spring Self-Activated Expander in bilateral distalization of maxillary molars using CBCT in Egyptian people. The main question it aims to answer are: • If bone supported Fast Back and bone supported modified Leaf Spring Self-Activated Expander will be effective in bilateral distalization of maxillary molars The patients will be selected according to the following criteria: 1. Patient with full permanent dentition. 2. Good oral hygiene. 3. None of the patients had received any orthodontic treatment. 4. Class II molar relationship. 5. Minimal or no crowding in the mandibular arch. 6. Non-extraction treatment plan with molar distalization. 7. Low angle cases. 8. No medical problems or active periodontal disease. Researchers will compare between bone supported Fast Back appliance and bone supported modified Leaf Spring Self-Activated and see if they will be effective in maxillary molars distalization.
This clinical trial compares the effectiveness of a myofunctional appliance that uses a clear and modified twin block appliance with an expander made from 2mm biocompatible polyethylene terephthalate modified with Glycol thermoplastic material with a conventional twin block appliance with an expander. The trial will be conducted on adolescent patients with class II division 1.
This clinical study will be directed to compare the effect of presence or absence of third molar on distalization of the upper posterior segment by using carriere motion appliance
Class II malocclusion with excessive overjet is one of the most common malocclusions among children and adolescents. The overall goal of the project is to analyze orthodontic treatment of Class II malocclusion with excessive overjet when the treatment is started in different ages and treated with removable and/or fixed appliance. Treatment initiated before the age of eleven is performed with a removable functional appliance, Headgear Activator (HGA). Treatment starting in early adolescence is performed with fixed orthodontic appliance (FA). The hypotheses are: - Treatment with HGA at the age of nine or eleven is effective. No spontaneous correction of the malocclusion is expected in the untreated control group. - Patient experience, treatment effect and cost-effectiveness are equivalent whether the treatment with HGA is initiated at the age of nine or eleven. - Treatment results, patient experience and treatment- and cost-effectiveness are equivalent whether treatment is initiated early with HGA or initiated in early adolescence with FA. - The treatment of Class II malocclusion with excessive overjet renders long-term treatment stability and patient satisfaction.
The aim of this longitudinal randomized investigation is to determine the long-term effects of early headgear treatment on craniofacial structures and dental arches, compared to treatment started later, during the most active growth period in Class II patients. The aim was further to find out the possible benefits and the burden of early treatment to the patients and parents of these common malocclusions, when compared to groups treated later, but with the same methods as much as possible. The hypothesis is that the timing of treatment has significant effects on orthodontic treatment total time, the general outcome of the treatment, and the compliance of the patient.
