简要总结
This study aimed to compare the effectiveness and efficiency of miniscrew-supported and standard frog molar distalizing appliances.
详细描述
A prospective randomized clinical trial study was carried out on twenty healthy Egyptian subjects, each required molar distalization as part of their comprehensive orthodontic treatment. The subjects were selected and treated at the outpatient clinic of the Orthodontic Department, Faculty of Dentistry, Ain-Shams University.
The inclusion criteria in this subject selection in this study was as follows;
- All the subjects had an age range from 11 to 16 years with a mean of ±13.5 years.
- All the subjects had skeletal Class 1 or mild skeletal Class 2 due to maxillary excess.
- All the subjects had bilateral Class II molar relationship.
- All subjects were free from any dental anomalies.
- All subjects had good oral hygiene. The exclusion criteria in this study was as follows; 1- Missing permanent teeth with exception of 3rd molar. 2- Previous orthodontic treatment. 3- Systemic disease that may influence orthodontic treatment and drug intake. 4- Periodontal disease. 5- Functional mandibular deviations and facial asymmetry. 6- History of parafunctional habits.
The subjects were equally and randomly divided into two groups; group A and group B which included ten subjects per group. These groups were classified according to the type of distalizer utilized:
- Group A: included ten subjects utilizing the conventional frog molar distalizing appliance (CF).
- Group B: included ten subjects utilizing the Miniscrews-supported frog molar distalizing appliance (MSF)
