Design Sixteen digital intraoral impressions were selected, and resin models were printed with a 3D printer. Forty band-loop space maintainers were fabricated (20 each for both the conventional and digital groups). 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. 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. The mean quadratic deviation (root mean square, RMS) was calculated. The RMS values between the groups were evaluated with Student's t test. Statistical significance was set at p No statistical significance was found between the conventional and digital groups (p = .56). Conclusions Within the limitations of this study, the band fit of conventional and CAD/CAM-fabricated space maintainers had no difference. Future research into CAD/CAM-fabricated appliances from different perspectives such as fracture strength and patient comfort is warranted.eninfo:eu-repo/semantics/closedAccessCADCAMpaediatric dentistryspace maintenancethree-dimensional printingArticleQ1Q1325764771WOS:00079948710000135122341
