Materials and Methods: Three groups of Class II subjects were included in this retrospective study: an early treatment (EarlyTx) group that first presented at age 7 to 9.5 years (n ¼ 54), a late treatment (LateTx) group whose first orthodontic visit occurred between ages 12 and 15 (n ¼ 58), and an untreated Class II (UnTx) group to assess the pretreatment comparability of the two treated groups (n¼51). Thirteen conventional cephalometric measurements were reported for each group and Class II molar severity was measured on the study casts of the EarlyTx and LateTx groups.
Results: Successful Class II correction was observed in approximately three quarters of both the EarlyTx group and the LateTx group at the end of treatment. EarlyTx patients had fewer permanent teeth extracted than did the LateTx patients (5.6% vs 37.9%, P , .001) and spent less time in fullbonded appliance therapy in the permanent dentition than did LateTx patients (1.7 6 0.8 vs 2.6 6 0.7years, P , .001). When supervision time is included, the EarlyTx group had longer total treatment time and averaged more visits than did the LateTx group (53.1 6 18. 8 vs 33.7 6 8.3, P, .0001). Fifty-five percent of the LateTx extraction cases involved removal of the maxillary first premolars only and were finished in a Class II molar relationship.
Conclusion: EarlyTx comprehensive mixed-dentition treatment was an effective modality for early correction of Class II malocclusions. (Angle Orthod. 2017;87:56–67)},
