In Vitro Implant Impression Accuracy Using a New Photopolymerizing SDR Splinting Material

“…To evaluate both position and orientation, the first set of points was used to construct the upper plane of the analogues, while the second set of points was used to obtain fitting circles that were constrained to lie on those planes; thus, the spatial (x,y,z) coordinates of the center of the fitting circles estimate the positions of analogues. The fitting algorithms implemented for the 3D geometries reconstruction were validated in a previous study, and their contribution to the experimental measurement uncertainty is negligible …”

An International Survey among Prosthodontists of the Use of Mandibular Implant‐Supported Dental Prostheses

“…An interesting finding was that 50% of all frameworks were fabricated using milling technique, which seems to have gained popularity among dentists worldwide. Milling technology allowed for higher precision/improved fit as compared with the traditional casting technique with noble/high noble alloys . The use of base metal frameworks such as chrome cobalt and titanium has also substantially reduced the cost for prostheses when compared with traditional noble/high noble alloys.…”

“…Although there is an array of published studies on implant treatments, little is known about the number of implants preferred among dentists in various countries for the support of fixed and removable dental prostheses. Moreover, choice of materials for implant‐supported fixed and removable dental prostheses varies between dentists and also between countries depending on factors such as insurance systems and national standard of care guidelines …”

Prosthetic Improvement of Pronounced Buccally Positioned Zygomatic Implants: A Clinical Report

“…Regarding the framework fabrication method, the overcastable components used for the present patient have shown to lead to a more passive framework than the entirely calcinable ones . However, the most passive frameworks can be obtained from computer aided design/computer aided manufacturing (CAD/CAM) systems, which allow the fabrication of metallic and ceramic milled frameworks . Despite these considerations, a CAD/CAM system was not used in this clinical report because they are still expensive for framework fabrication.…”
