Abstract: There is described a scanner having a frame with a support, two lasers attached to the frame and two optical sensors attached to the frame, the lasers and optical sensors being positioned and oriented to reduce shadowing effects for the cameras and for the laser lines while covering close to 100% of the surface of an object to be imaged and reducing the scanning time.

Abstract: This invention is a novel method for making zirconia ceramic from hybrid composite biomaterials. The inorganic particles of zirconium oxide with a desired size and controlled shape were synthesized in an alcohol solution in the presence of water and a morphologic catalyst. Zirconium alkoxides and/or zirconium oxychloride, Yttrium alkoxide, Yttrium nitrate hexahydrate and Yttrium chloride, were used as the precursor materials for the preparation of zirconium oxide colloidal suspensions. Particle surface modification by the introduction of polymerization precursors was carried out in colloidal suspension. Highly-filled and well dispersed composite biomaterials with thermoplastic and/or thermo-hardening matrices are easily obtained using several polymerization techniques, like catalytic polymerization, controlled free radical polymerization, and polycondensation.

Abstract: The present invention provides an implant system of facilitated use and installation which comprise an implant and a prosthesis support and a method of installation thereof. The prosthesis support disclosed herein includes an abutment and a collar member. Prior art implant systems are mostly made of metallic parts which are assembled with a screw and are shaped to receive a tooth prosthesis. The design of the abutment allows it to be made from highly filled composite materials being of a better optical quality and being easily machinable and further allows its installation without the use of a screwing member. The design of the collar member allows minimization of bacteria growth and tartar formation. The optimization of the implant system proposed herein may reduce stress to the jaw bone and therefore minimize the risk of injury for the patient.
