简要总结
Effects of modified fixed twin block versus removable twin block on skeletal class 2 growing patients with mandibular deficiency:
A Randomized Clinical Trial
详细描述
The main objective of the study is to evaluate the effects of the modified fixed TB on class 2 growing cases and to compare its effect to the conventional removable TB
Research question Does the modified fixed twin block have the same effects as removable twin block during treatment of skeletal class 2 growing patients with mandibular deficiency?
