About the Edition

Background. It is hypothesized that frameworks fabricated using the laser scanned Computer Numeric Controlled (CNC) technique are more accurately fitted to the prosthetic analogue than conventional cast-over ones. Objective. To compare the in vitro three-dimensional accuracy of fit of the CNC-milled implant titanium frameworks to conventional cast-over ones. Methods. Nine cast-over frameworks were fabricated on mandibular models following the conventional fabrication technique. The fabrication of the laser-scanned CNC milled frameworks involved scanning of the implants analogues" using a Coordinate Measuring machine (CMM). The cast-over frameworks were then laser scanned, and CNC frameworks that match their outline were fabricated. The accuracy of fit was measured using CMM and a special computer software. Results. The CNC frameworks showed significantly less distortion along the x-axis and the horizontal plane (x+y) (p = 0.01). The y, z axes and the three-dimensional distortion showed an overall trend of less distortion in the CNC frameworks. Conclusion . The CNC-milling technique yields a more accurate fit than the conventional technique. However, in vivo studies are needed to investigate the clinical significance of this recorded difference.
