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.
Introduction: This study aims to evaluate the gingivitis, periodontal profile and malocclusion in children and adolescents with diabetes. Methods: The sample consisted of 36 children, who were distributed into two groups: DM; n=18 and NDM; n=18. Periodontal parameters considered were plaque Index (PI), gingival Index (GI), probing depth of pocket (PPD), gingival recession (GR) and clinical attachment level (CAL). Gingival biotype clinical parameters: Gingival transparency to probing, Height of keratinized mucosa and Gingival thickness on permanent incisors and molars. Malocclusion were evaluated by the Dental Aesthetic Index (DAI) and the Angle's Classification. The statistical analyses were Shapiro Wilk test and T test.
The aim of the present study was to retrospectively compare the clinical use of high-pull headgear versus AMCOP bioactivators for hyperdivergent pediatric patients. Cephalometric radiographs from pediatric patients treated at the Unit of Orthodontics and Pediatric Dentistry, Section of Dentistry, Department of Clinical, Surgical, Diagnostic and Pediatric Sciences, University of Pavia, Pavia, Italy and at the private practice of Dr. Cardarelli, Isernia, Italy will be collected. Cephalometric tracing from Giannì analysis will be performed at the baseline (T0) and after 18 months of treatment (T1).
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 study will aim to evaluate the dental and skeletal effect of the Transpalatal arch and Nance holding arch as a space maintainers in children.
evaluate and compare the efficiency between elastomeric chains and burston T-loop retractors in terms of rate of maxillary canine retraction and canine movements
This study hypotheses that using low medial cut osteotomy BSSO in mandibular setback can be an efficient and effective method to limit the bony segment interferences , decreasing muscles stripping during osteotomy ,decrease condylar torque and so securing preoperative condylar position during BSSO in comparison with using high medial cut BSSO.
The purpose is to fill knowledge gaps identified for orthodontic treatment using a novel study design that has not been implemented in the dental field or in orthodontics. The study design comprises an analysis, where outcomes of two techniques are assessed at several efficacy levels by different methods. Moreover, the project is designed to include a longtime follow-up that is unique in orthodontic treatment. The aim is to compare two techniques with buccally fixed appliance in a multicenter RCT of adolescents aged 12 to 17 years with crowding and tooth displacement. In the intervention group, patients will be treated with a self-ligating bracket system, and in the control group with a conventional bracket system. Outcomes will be assessed from the clinical, patients' and economic perspectives as: - Tooth alignment, function and adverse side effects - Patients' perception of pain, function and quality of life - Cost-effectiveness.
study will be directed to evaluate two approaches of microosteoperforations during skeletally anchored maxillary expansion
The study will monitor changes induced by orthodontic treatment and in the retention period, two years after the end of orthodontic treatment. The alignment of teeth, hygiene and gingiva will be assessed. Efficiency of two types of fixed appliances in active phase will be compared - esthetic and metal. Efficiency of two types of retention appliances in retention phase will be compared - fixed and removable. The benefits of orthodontic treatment to be studied are aesthetic concerns, dental self-confidence, self-esteem, social contacts, psychological influences, and chewing limitation. The stability of personality traits, body image and perfectionism will also be analyzed, as well as the extent to which these dimensions modify the reporting of psychosocial effects of malocclusion treatment.
