OBJECTIVE
Evaluation of head and cervical spine posture and estimation of sample size.
METHODS
Thirty eligible participants who required functional therapy were randomly assigned to the Control group (C), Twin Block group (TB), or the Bionator group (B). Randomization was accomplished by means of blocks of fixed size stratified by sex and age, with the allocations concealed in opaque and sealed envelopes.
RESULTS
Significant differences were identified between the pre -and post-functional SNB ( = 0.024) and ANB ( = 0.034) angles in the Twin Block group and SNA ( = 0. 019) and ANB ( = 0. 028) angles in the Bionator group. No statistically significant changes were seen in the head or cervical variables in the three groups.
CONCLUSION
The functional appliance did not cause any statistical change in head posture or cervical spinal column in comparison with the non-treatment group.
目的
评估头颈部姿势并估计样本量。
方法
将 30 名需要功能治疗的合格参与者随机分配到对照组（C）、双板组（TB）或 Bionator 组（B）。通过按性别和年龄分层的固定大小的块进行随机分组，将分配情况隐藏在不透明和密封的信封中。
结果
在 Twin Block 组中，SNB（=0.024）和 ANB（=0.034）角度的治疗前后有显著差异，在 Bionator 组中，SNA（=0.019）和 ANB（=0.028）角度的治疗前后有显著差异。三组的头或颈椎变量均未发生统计学显著变化。
结论
与非治疗组相比，功能性矫治器不会对头位或颈椎产生任何统计学上的改变。
