简要总结
A comparative evaluation of skeletal and dental changes following mandibular en masse distalization with buccal shelf screws - A randomised controlled trial between two orthodontic mechanics
Aim: To compare and evaluate the skeletal and dental changes following lower en masse distalization with buccal shelf screws between two orthodontic mechanics
Sample size: 18 patients
Randomised controlled clinical trial
Group 1: Distalization with a statically determinate system
Group 2: Distalization with a statically indeterminate system
Methodology: Linear and angular skeletal and dental changes calculated between the pre distalization and post distalization CBCT values.
The rate of lower molar distlization to be calculated by dividing the amount of distalization by the time taken to achieve Angle’s Class l molar relationship.
Primary and secondary parameters to be measured from the pre and post distalization CBCTs and the difference between the two orthodontic biomechanics to be calculated.
