The purpose of this retrospective study was to compare the COCR differences in pretreatment and posttreatment CI II Div I patients. Similar sample groups were chosen from patients of the graduate orthodontic clinic at Loma Linda University School of Dentistry.
Each patient's models were mounted on a Sam II articulator using a face bow transfer and a centric relation check bite. The COCR discrepancies in the anterior-posterior, superior-inferior, and side-shift dimensions were determined with the Mandibular Position Indicator.
Using t-test analyses, statistically significant differences were found between the pretreatment and posttreatment groups, with the posttreatment sample exhibiting a smaller CO-CR discrepancy than the pretreatment sample.
