Future research into CAD/CAM-fabricated appliances from different perspectives such as fracture strength and patient comfort is warranted.ĬAD/CAM paediatric dentistry space maintenance three-dimensional printing. Within the limitations of this study, the band fit of conventional and CAD/CAM-fabricated space maintainers had no difference. No statistical significance was found between the conventional and digital groups (p =. The RMS values between the groups were evaluated with Student's t test. The mean quadratic deviation (root mean square, RMS) was calculated. Digital evaluation was carried out using dual scan method by superimposing two scans of resin models covered with or without a silicone layer on the abutment tooth. To evaluate the band fit of conventional and CAD/CAM-fabricated space maintainers, cement space was visualized with low-viscosity condensation silicone material on resin models. Forty band-loop space maintainers were fabricated (20 each for both the conventional and digital groups).
Sixteen digital intraoral impressions were selected, and resin models were printed with a 3D printer.
The aim of this in vitro study was to evaluate the band fit of metallic band-loop space maintainers fabricated by conventional and 3D printing technologies for clinical applications.
