Antimicrobial polymer composite materials are disclosed that are suitable for making oral devices used in dental applications, such as denture bases. Acrylic resin composite materials comprising antimicrobial polymers and antimicrobial fillers provide reduction in common oral microorganisms after long-term aging, with reduced release rate of antimicrobial agents from the composite material. Antimicrobial polymers are prepared from compositions comprising acrylate and/or methacrylate monomers and polymerizable quaternary ammonium silicon-containing compounds.

Various embodiments of improved methods of creating removable or fixed over-implant dentures are disclosed that make patients look younger without plastic surgery. Different combinations of dentures may be used. The Denture facelift System (DFS) improves the look of virtually some facial defects or aging wrinkles, improves appearance as called anti-aging. These methods provide state-of-the-art dentures while decreasing the number of clinic visits for the patient. The embodiments employ specialized impression trays, a facial and bite registration instrument, and teeth selection kit strips of films to increase the efficiency of the denture-making process. The facial registration instrument comprises adjustable rods and plates to secure a temporary measuring grid above the patient's face, allowing for more accurate marking of anatomical features on wax bite blocks.

Process for transforming synthetic and vegetable fibres into a non-woven fabric of the type which provides the following sequence of processing steps: flock opening step, during which fibrous materials of different shapes and sizes are transformed into fibre flocks of different lengths; drawing and treatment step of the material selected in the previous step; cutting and trimming step: once the drawing and treatment step of the material has been completed, the non-woven fabric is subject to longitudinal cutting and trimming, to make a series of rolls, usually two or three, for final use, characterised in that, after the opening step, the flocks are transferred to a condenser, where the long-fibre flocks are separated from the short-fibre flocks, by means of a perforated mesh screen.

The metal porous body according to one aspect of the present invention has a framework of a three-dimensional network structure. The framework is hollow inside and is formed of a metal film, and the metal film contains titanium metal or titanium alloy as the main component.

A multi-unit abutment aligning a dental implant and a screw-attached prosthesis with copings is disclosed. The multi-unit abutment has a threaded base post for attachment to the implant and a ball portion. A swivel post into the implant with the multi-unit assembly in a linear configuration. The swivel shell is then positioned and fixed at a desired tilt and azimuthal angle. The swivel shell has a mating surface for a coping. The lock screw remains accessible through an aperture in the coping when the prosthesis is positioned on the implant abutments. Different embodiments are disclosed for capturing the swivel shell on the ball. Methods for improving passive alignment of the prosthesis to the implants are described.
