Answer
-
Both true
-
First true, second false
-
First false, second true
-
Both false
Question 7
Question
The best window of opportunity for maxillary expansion is before the onset of puberty. The optimal window of opportunity for mandibular growth is during the peak skeletal growth velocity because the condylar growth is accelerated.
