Patent number: 8167618Abstract: The stability of an implant (5) which is fitted in a jaw bone hole created by tooth root extraction is increased using osteoinductive material. Bone formation in the space between the implant and the bone wall is also stimulated. In an initial stage, the implant is anchored or fitted in the hole. With its outer parts (5a) the implant extends into a part (4a) of the hole which has a cross-sectional area exceeding the crossectional area of the outer parts (5a) of the implant. The soft tissue of the jaw bone, with possible periosteum, covers the implant and the space to form a closed space (4a). The bioactive material consists of growth-stimulating substances (GSS) arranged on the implant. In a stage of incorporation, GSS passes outward into body fluid which has penetrated into the closed space and interacts with cells present in the fluid so that new bone is formed around the outer pats (5a) of the implant. The invention also relates to a use and to an implant.Type: GrantFiled: September 15, 2008Date of Patent: May 1, 2012Assignee: Nobel Biocare AB (publ)Inventor: Jan Hall

Patent number: 8152856Abstract: 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.Type: GrantFiled: March 29, 2010Date of Patent: April 10, 2012Assignee: Nobel Biocare AB (publ.)Inventors: Jan Hall, Jukka Lausmaa

Patent number: 8113834Abstract: Two or more implants (8, 9, 10) are arranged in succession in the jaw bone (1) and bear or comprise growth-stimulating substances (25), here called GSS, which, as a function of secretion of body fluid at the implants, are intended to be released and form new bone (11-15) around the implants. The implants are designed to work with a release process for GSS, permitting a leveling-out effect along the extent of the jaw bone in the horizontal and/or vertical direction and/or a level-raising effect in the vertical direction. In this way it is possible to achieve optimum positions for the implants without the risk of reduced stability and/or compromised esthetics.Type: GrantFiled: May 23, 2008Date of Patent: February 14, 2012Assignee: Nobel Biocare AB (Publ)Inventor: Jan Hall

Publication number: 20090047632Abstract: 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).Type: ApplicationFiled: September 16, 2008Publication date: February 19, 2009Applicant: Nobel Biocare AB (publ.)Inventor: Jan Hall

Patent number: 6547565Abstract: An instrument is connected to a driving-in tool or drilling tool for elements on or in the form of an implant or drill for dentine. The tool includes an electric motor, the torque of which can be sensed, and which can be controlled by a control unit. A display unit is arranged so as to partly or fully display a curve representing the driving-in function performed. A tightening function is determined by a scale based on the slope of the curve, wherein a flatter slope represents a lower quality function and a steeper slope represents a higher quality function. A frictional resistance which exists for an element during the driving-in of the element can be determined in order to allow secure locking (preload) of the element by tension in the material of the element. A torque-time curve can be used assess the bone quality of bone being implanted or drilled.Type: GrantFiled: March 19, 2001Date of Patent: April 15, 2003Assignee: Nobel Biocare AB (publ)Inventors: Andrew Dawood, Anders Petersson
