ABSTRACT

Objective

To compare treatment duration and quality between standard vs computer-aided design/computer-aided manufacturing (CAD/CAM) customized self-ligating systems using indirect bonding with both.

Materials and Methods

This comparative trial included 24 patients: 12 treated with a CAD/CAM custom indirect bonding self-ligating system (CAD/CAM) and 12 others treated with an indirect bonding self-ligating standard system (I-STD). For each group, overall orthodontic treatment (OT) time was calculated and included the time needed to place each arch as well as the duration of the alignment and fine-tuning phases. The quality of the final result was analyzed using the American Board of Orthodontics Cast-Radiograph Evaluation. Patient-reported outcome measures (PROMs) were also evaluated.

Results

Patient characteristics were similar between the 2 groups except for age, which was slightly lower in the I-SDT group. Overall OT time was increased by 26% in the I-STD group compared with the CAD/CAM group (497 ± 40 days vs 393 ± 55 days, P = 0.0002) due to a shorter fine-tuning phase in the latter group (P<0.01). No difference was found between the groups for alignment phase. Quality of the final result was similar (I-STD, 25.7 ± 6.1; CAD/CAM, 21.6 ± 6.3) among the groups. Finally, no difference was found in the PROMs variables.

Conclusions

Despite a 26% longer OT time when compared with the CAD/CAM customized bracket system, the indirect bonding self-ligating bracket system demonstrated the same quality of treatment. PROMs demonstrated a high level of acceptance and satisfaction for both techniques.
