Class II Subdivision refers to the asymmetric molar relationship that can be commonly accounted to dental and occasionally to the skeletal disharmony. Furthermore, the discrepancy may be present in the maxilla or the mandible. To put it differently Class II subdivision is a heterogeneous group of malocclusions and cannot be considered as a discrete entity to be treated with predefined specific strategies.
Treatment goals encompass the usual cook-book approach and entail the orthodontists to think-before-act strategy considering all the parameters that may be affected favorably or deleteriously while executing a specific plan. Treatment options may vary from non-extraction to four premolar extractions depending upon the site and severity of the malocclusion.
Another consideration would be the indispensable side-effects of the biomechanics involved that may be symmetric or asymmetric, again depending upon the needs of the patient. These not only require thorough diagnosis but also clarity in the treatment goals.
This piece of literature would briefly outline the important considerations while treating Class II Subdivision cases with the help of examples of three patients bearing different etiologies treated with contrasting strategies.
