| 20100185293 | LAYER ARRANGED ON IMPLANT FOR BONE OR TISSUE STRUCTURE, SUCH AN IMPLANT, AND A METHOD FOR APPLICATION OF THE LAYER - A layer is arranged on an implant for bone or tissue structure. The layer constitutes a boundary or barrier between the actual or unoxidized body of the implant and the structure for the purpose of increasing retention and has, in this context, a substantial thickness. The layer is designed with a channel network which gives the layer a substantial porosity. The channel network is designed with mouths which face towards the structure and whose respective cross-sectional diameters, at the surface of the layer facing towards the structure, are substantially less than the respective extents of the channels in and down into the layer as seen from the said surface. | 07-22-2010 |

| 20090047632 | ARRANGEMENT FOR IMPLANTS BEARING GROWTH-STIMULATING SUBSTANCE OR SUBSTANCES, AND ONE SUCH IMPLANT - An implant bears growth-stimulating substance(s), here called GSS, which can be released when the implant is arranged in a jaw bone hole. The release takes place in interaction with secreted, cell-containing body fluid so as to form new bone alongside the implant. The implant is arranged with an outer surface which can comprise the outer parts of a thread or can consist of bearing surfaces parallel to the inner wall of the jaw bone hole. First portions of the outer surface have first diameters or radii, and second portions have second diameters or radii smaller than the first diameters or radii. The implant bears against or cooperates with the hole wall via the first portions and, by means of the second portions and together with the hole wall, forms one or more closed spaces into which body fluid can penetrate and GSS can be released. The implant can alternatively be designed with a shape or shapes substantially corresponding to the tooth root configuration(s). The new bond formation is made effective in this way, and great stability can be obtained for the implant in its position in the jaw bone. | 02-19-2009 |
| 20090047631 | ARRANGEMENT FOR USING OSTEOINDUCTIVE OR BIOACTIVE MATERIAL TO INDUCE BONE AND/OR INCREASE THE STABILITY OF IMPLANTS IN THE JAW BONE, AND AN IMPLANT INTENDED FOR THIS PURPOSE - The stability of an implant ( | 02-19-2009 |
| 20090024220 | ARRANGEMENT FOR INCREASING THE STRESS RESISTANCE OF IMPLANTS AND ONE SUCH IMPLANT - An arrangement and an implant are provided for increasing the stress resistance of the implant arranged in an upper jaw bone ( | 01-22-2009 |
| 20080228279 | ARRANGEMENT OF TWO OR MORE IMPLANTS PROVIDED WITH GROWTH-STIMULATING SUBSTANCE(S) - Two or more implants ( | 09-18-2008 |
| 20080213725 | Method and Arrangement for a Dental Installation - A substrate has or is provided on a surface with a first porosity. A dispersion with low-viscosity liquid is applied to the surface in order to form a ceramic layer with a second porosity having preferably larger and/or more pores than in the first porosity. The liquid has the ability to be sucked by capillary force into the first pore formation and, in a first stage, to retain on the surface material and/or liquid particles which do not penetrate into this first pore formation, and which contribute to the continued construction of the layer. In a second stage, the substrate is subjected to sintering in which the particles finally forming the layer are held together with intermediate spaces which consist of or are included in the second porosity, the spaces being formed either by the fact that material and liquid particles separate from the particles finally forming the layer are driven off during the sintering and/or by the fact that the particles forming the layer are chosen with a particle size which means that the last-mentioned particles are held together after the sintering despite the intermediate spaces. The invention also relates to an arrangement. By means of the invention, a dental product can be provided with excellent porosity which is advantageous in connection with dental installations. | 09-04-2008 |
