  • Patent number: 10293153
    Abstract: An implantable medical device can include an electrode substrate electrically connected to at least one electrode. The device can have a pseudoporous surface across the electrode substrate and electrode. This surface can result in a real surface area (RSA) greater than the geometric surface area (GSA) of the device. The pseudoporous surface can be a macroporous surface enabling a charge injection capacity greater than 1 mC/cm2 while minimizing rejection of the device by surrounding tissue in chronic implant applications. The electrode can be a thin layer of conductive material, such as platinum or another metal, conformally deposited on the pseudoporous surface of the electrode substrate. A method of making the implantable device can include forming the device having an electrode substrate and at least one electrode electrically coupled to the electrode substrate, and forming a pseudoporous surface on the electrode substrate and electrode.

  • Patent number: 9443292
    Abstract: This disclosure pertains to novel devices, methods, and computer readable media for performing “blind” color defringing on images. In one embodiment, the blind defringing process begins with blind color edge alignment. This process largely cancels every kind of fringe, except for axial chromatic aberration. Next, the process looks at the edges and computes natural high and low colors to either side of the edge, attempting to get new pixel colors that aren't contaminated by the fringe color. Next, the process resolves the pixel's estimated new color by interpolating between the low and high colors, based on the green variation across the edge and the amount of green in the pixel that is being repaired. Care is taken to prevent artifacts in areas that generally do not fringe, like red-black boundaries and skin tone. Finally, the process computes the final repaired color by using luminance-scaling of the new pixel color estimate.

    Abstract: Comparative effectiveness of various oral care products such as dentifrices on preventing dental erosion may be demonstrated using simulated enamel. A substrate is prepared. A mineral layer to simulate dental enamel is nucleated by solution growth on the substrate surface. Alternatively, the mineral layer may be nucleated on a template comprising a self-assembled monolayer formed on a gold layer deposited on the substrate surface. The mineral layer may comprise a homogeneous layer of hydroxyapatite or a thin veneer of hydroxyapatite on a layer of amorphous calcium phosphate. The simulated enamel is then optionally treated with an oral care product and subjected to an acid challenge. The amount of mineral layer remaining after the acid challenge illustrates the effectiveness or non-effectiveness of the oral care product at preventing dental erosion.

  • Publication number: 20150140512
    Abstract: A retention insert (1), for connecting a dental prosthesis structure to a dental implant or capping structure having a head designed for a press-fit connection, comprises a substantially circular disc-shaped end face (12), and a substantially ring-shaped retention edge (11), which protrudes from the end face (12) and has an outer surface (114). The end face (12) has an opening (121), and, starting from an end (11b) of the retention edge (11) directed away from the end face (12), a substantially axial slit (14) extends through the retention edge (11) and the end face (12) to the opening (121) of the end face (12). Connected to the opening on the end face, the slit of the retention insert according to the invention is a relatively simple structure which ensures that the retention insert, and in particular the retention edge thereof, has an elasticity sufficient for snap-fitting it onto the head or the patrix head.

  • Publication number: 20150132719
    Abstract: A porous metal augment is sized for use in mandibular or maxillar bone. The porous metal material of the augment facilitates and promotes ingrowth of the surrounding bone into the porous metal structure, thereby rebuilding a suitable foundation for affixation of dental implants. A non-porous core or insert can be embedded within the porous metal body of the augment, and can be made of a material suitable for firm threaded fixation of dental implants thereto. For example, the metal core can be formed of a titanium structure that has sufficient strength and resiliency to form a firm and long lasting threaded connection with a threaded stem of a dental implant.

  • Publication number: 20150118651
    Abstract: Dental prosthetic assembly (27) comprising a dental implant (2a, 2b) and a transfixed dental prosthesis (3). A connecting device (1) comprises: a lock (5) which has at least two radial wings (6a) and is mounted rotatably and retained in translation in one of dental implant (2a, 2b) or dental prosthesis (3), a retention cavity (15), provided on its periphery with protuberances (16a) extending radially towards the centre of the retention cavity (15), which is formed in the other of dental implant (2a, 2b) or dental prosthesis (3). The radial wings (6a) and the protuberances (16a) are configured and dimensioned in such a way as to cooperate by rotation of the lock (5) in order to keep the dental prosthesis (3) transfixed on the dental implant (2a, 2b), and in such a way as to allow the lock (5) and its radial wings (6a) to penetrate into the retention cavity (15) by a simple movement of axial translation.

  • Publication number: 20150118649
    Abstract: The present invention relates to a surface treatment method for an implant, comprising: providing an implant; and forming a ceramic layer on a surface of the implant by atomic layer deposition, wherein the ceramic layer has a thickness of 5-150 nm; a root mean square roughness increase in a range of 15 nm or less; and a friction coefficient of 0.1-0.5. The ceramic layer formed on the surface of the implant can fully encapsulate the surface of the implant with excellent uniformity to effectively block the free metal ions dissociated from the implant. Moreover, it has anti-oxidation and anti-corrosion effects, and greatly enhances the biocompatibility of the implant.
