Still overall (as lips flatten anyway), I was very pleased. (Fig 13 – 19) Patient returned January 2009. (Fig 20) I noted the molars had drifted into a slight Class II. This was due to the fact that it is difficult to maintain a Class I molar in a mixed dentition. The primary molars are basically blocks on blocks and provide no intercuspation (in contrast to premolars), which is essential to main-taining a Class I. Also there were some slight rotations in the anterior teeth. I advised the parents to resume with Phase II therapy. Fig. 20 12 November/December 2011 JAOS
