What does the primary outcome measure?
overjet (time frame: 1 day between the maximum intercuspation and centric relation records). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
