Clinical outcomes for patients finished with the SureSmile™ method compared with conventional fixed orthodontic therapy.
OBJECTIVE
Utilize American Board of Orthodontics (ABO) cast/radiographic evaluation (CRE) to compare a series of 63 consecutive patients, finished with manual wire bending (conventional) treatment, vs a subsequent series of 69 consecutive patients, finished by the same orthodontist using the SureSmile™ (SS) method.


METHODS
Records of 132 nonextraction patients were scored by a calibrated examiner blinded to treatment mode. Age and discrepancy index (DI) between groups were compared by t-tests. A chi-square test was used to compare for differences in sex and whether the patient was treated using braces only (no orthopedic correction). Analysis of covariance tested for differences in CRE outcomes and treatment times, with sex and DI included as covariates. A logarithmic transformation of CRE outcomes and treatment times was used because their distributions were skewed. Significance was defined as P < .05.


RESULTS
Compared with conventional finishing, SS patients had significantly lower DI scores, less treatment time (∼7 months), and better CRE scores for first-order alignment-rotation and interproximal space closure; however, second-order root angulation (RA) was inferior.


CONCLUSIONS
SS patients were treated in less time to better CRE scores for first-order rotation (AR) and interproximal space closure (IC) but on the average, malocclusions were less complex and second order root alignment was inferior, compared with patients finished with manual wire bending.
