<Abstract><AbstractText Label="PURPOSE" NlmCategory="OBJECTIVE">To compare the in vitro 3-dimensional (3D) accuracy of fit of laser-scanned Computer Numeric Controlled (CNC)-milled implant titanium frameworks to that of conventional cast frameworks.</AbstractText>
<AbstractText Label="MATERIALS AND METHODS" NlmCategory="METHODS">Nine cast frameworks were fabricated on the mandibular master casts of 9 patients with 5 implants each following the well-established conventional fabrication technique. The frameworks were then laser scanned, and 9 CNC-milled titanium frameworks matching the outline of the conventional frameworks were fabricated. The accuracy of fit of both framework types was measured using a contact-type coordinate measuring machine and a computer program developed specifically for this purpose. Statistical analysis was done by a series of paired ttests.</AbstractText>
<AbstractText Label="RESULTS" NlmCategory="RESULTS">The laser-scanned CNC-milled frameworks showed significantly less distortion along the x-axis (transversal, d(x)) compared with the conventional frameworks (means: 33.7 microm and 49.2 microm, respectively) (P = .011). The titanium frameworks also demonstrated significantly less distortion on the horizontal plane compared with the conventional frameworks (means: 56 microm and 85 microm, respectively) (P = .012). The d(y) (sagittal) and d(z) (vertical) axes and total 3D distortion (square root of dx(2) + dy(2) + dz(2)) showed less distortion overall in the laser-scanned CNC-milled frameworks, but this was not statistically significant (mean: 22.3 vs 35.6 microm, 13.3 vs 59.2 microm, 51 vs 114.1 microm, respectively, for y, z, and 3D distortion).</AbstractText>
<AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">Within the limitations of this study, fabrication of an implant-prosthodontic framework using the CNC milling technique yields a more accurate fit than the currently used cast technique. In vivo studies are needed to investigate the clinical significance of this recorded difference.</AbstractText>
