Question:
Is there a difference in treatment duration between a customised fixed appliance system and a noncustomised system?
Study design:
Randomised controlled trial
Intervention:
Patients aged 12-30 years requiring fixed orthodontic treatment were eligible and were randomly allocated to treatment with the Insignia customized orthodontic system or the Damon Q noncustomized orthodontic system. 
Outcome measure:
The primary outcome measure was treatment duration. Secondary outcomes were quality of treatment result; the degree of improvement graded using the Peer Assessment Rating (PAR) score; number of visits from the first visit after bonding to debonding; number of loose brackets; time required for treatment planning; and number of complaints.

Results:
180 patients entered the trial. 4 were lost to follow up and 2 did not complete treatment, so 174 were analysed. Treatment duration was 1.29 ± 0.35 years in the customized group and 1.24 ± 0.37 years in the noncustomized group. The PAR did not differ significantly between groups. However, the orthodontist had a significant effect on treatment duration, quality of treatment outcome, and number of visits (P < 0.05). Compared to the noncustomized group, the customized group had more loose brackets, a longer planning time, and more complaints. 
Conclusions:
The customized orthodontic system was not associated with significantly reduced treatment duration, and treatment quality was comparable between the 2 systems.
