      abstract     = {A virtual guidance framework is used to assist the
                      conventional method of virtual implant planning system
                      (VIPS). The study null hypothesis was that its screw
                      placement accuracy is equal to that of conventional VIPS.In
                      34 distal radius sawbone models, 3D implant planning was
                      performed. A camera attached to the surgical drill was used
                      to support screw positioning. Differences of angles/tip
                      distances between planned and placed screws were identified
                      in intraoperative cone beam Computer tomography (CT) and
                      compared with already existing data from 22 patients treated
                      by conventional VIPS.The virtual guidance group showed tip
                      distances of 1.02 ± 0.56 mm, azimuth of
                      3.69° ± 4.34°, and inclination of 1.75° ± 1.37°,
                      whereas the VIPS group showed tip distances of
                      2.23 ± 0.99 mm (P < 0.001), azimuth of
                      23.17° ± 33.50° (P < 0.001), and inclination angle of
                      4.18° ± 6.29° (P = 0.001).The results reveal that
                      using a guidance framework leads to a higher accuracy in
                      screw placement compared with the conventional VIPS itself.},
