TREATED CASE SIX |
The diagnosis and 3-stage treatment of a young 7.7 year old girl with a difficult high angle Class II skeletal pattern and crowding. The MM angle reduced from 39° to 31° during treatment.



The diagnosis of high angle cases |
– recognising soft tissues factors – evaluating the hard tissue components |
The management of a three stage approach |
– careful overall planning at the start – separating the stages for effective treatment |
How to achieve orthopaedic change |
– techniques with functional appliances – the preferred timing for optimal improvement |
The extraction / non-extraction decision |
– relief of crowding with enamel reduction – the proclination of lower incisors as a factor |
Gummy smiles |
– possible causes, skeletal and muscular – why it may be unwise to attempt treatment |
