For most CL II children

early treatment is no more efficiently than later treatment & considerably less efficent

what are the indications for early CL II treatment?

Let's carefully label this as ol prof's opinion,his conclusions based on the current evidence

indications:

1)special concerns

2)esthetics/social acceptability

  phase I outcomes,psychological data

NC(north callorina):no difference in treated  vs. untreated children

munchester,UK( 大英曼徹斯特大學):greater improvment in treated children

mean overjat reduce  UNC   2.1mm

mean overjat reduce MUNCHESTER  6.2mm

 but at the end of phase 2   mancheater,there was no difference

3)susceptibility to trauma  (teeth or soft tissues)

4)skeletal maturation ahead of dental (usually girls),least likely to benefit from early treatment, the late maturing boy(?)

5)severe problem?

severity:no correlation with change in PAR score or ANB during treatment(!)

psychological severity-not malocclusion

                              severity is the indication for early treatment

6)face height problems(??)

              short face:functional appliance

              long face:headgear+functional appliance

The percentage of CL II children who meet these criteria?~unknown at present

enthusiatic reports: tend to have no contents

well- controlled reports:tend to have no enthusiam,but the truth is your best guide
