growth pattern. Angle’s Class III molar
relationship and a posterior crossbite on right
side with crowding and bidental
proclination.The dental midlines were non
coinciding and there was a mild occlusal
cant.(fig 1 and 2).
Thus etiology was thought to be developmental
– Hemimandibular hyperplasia
In particular,the radiograph and CT showed that
the mandibular right inferior border was much
bulkier than left inferior border. This difference
in mass was the cause of the facial asymmetry 1 .
Major problems were summarized as frontal
asymmetry, deviation of the chin, right posterior
crossbite, and non coinciding midlines.
However the patient had a coinciding centric
relation - centric occlusion.
