20110151026 | BONE TISSUE IMPLANT COMPRISING LITHIUM IONS - The present invention is based on that local administration of lithium ions in bone tissue has been found to improve the bone formation and bone mass upon implantation of a bone tissue implant in said bone tissue. | 06-23-2011 |
20110212416 | IMPLANT HAVING CIRCUMFERENTIALLY ORIENTED ROUGHNESS - A self-tapping implant includes a shaft including a coronal end, an apical end, an outer surface having a first axial section and a second axial section, and a self-tapping configuration at the first axial section. The first axial section may be located coronally of the second axial section. Each of the first and second axial sections may include a series of peaks being axially spaced apart by troughs. In addition, the axial spacing between the adjacent peaks in the first axial section may be different than the axial spacing between adjacent peaks in the second axial section. A coronal end portion of the shaft may include the first axial section of the outer surface, and an apical end portion of the shaft may include the second axial section of the outer surface. | 09-01-2011 |
20110306016 | Dental fixture - The invention relates to a dental fixture for insertion into a human jawbone. The fixture comprises a bone-contacting surface, wherein at least 15% of the bone-contacting surface is designed such that when a Gaussian 50 μm high-pass filter and a Gaussian 3 μm low-pass filter is applied to an original unfiltered set of measurement data which represents a topography of said surface and which is obtained at 50 times magnification by white light interferometry, the resulting filtered set of data presents a surface roughness having the roughness average parameter S | 12-15-2011 |
20120264083 | FIXTURE AND A FIXTURE SET AND A METHOD - The present invention relates to a fixture, such as a dental fixture, for insertion into a bore hole arranged in bone tissue, comprising a threaded leading portion and a threaded trailing portion located coronally of the leading portion. By a widened threading at the trailing portion, the bone tissue is subjected to a static strain beyond the yield strain of the bone tissue. The invention also relates to a fixture set and to a method of insertion of a fixture into a bore hole arranged in bone tissue. | 10-18-2012 |
20120264084 | FIXTURE - The present invention relates to a fixture for insertion into a bore hole arranged in bone tissue, comprising a threaded leading portion and a threaded trailing portion located coronally of the leading portion. | 10-18-2012 |
20120264085 | FIXTURE, A THREAD MAKER AND A FIXTURE SET - The invention relates to a fixture, such as a dental fixture, for insertion into a bore hole arranged in bone tissue. The fixture has two condensation portions which may be designed to provide the same or different tensile strain levels to the cortical and cancellous bone tissue, respectively. The invention also relates to a thread maker for making a female thread in bone tissue prior to insertion of a fixture. The invention further relates to a fixture set, comprising a thread maker and a fixture. | 10-18-2012 |
20120264086 | FIXTURE AND A FIXTURE SET - A fixture for insertion into a bore hole arranged in bone tissue is provided. The fixture has a threaded leading portion provided with at least one cutting edge for creating a female thread in the bone tissue, and a threaded trailing portion following the leading portion in the created female thread. Compared to the geometry of a thread peak of said cutting edge of the leading portion, a thread peak of the trailing portion is displaced or overdimensioned in at least one of the coronal and apical directions of the fixture so that a strain is provided to the bone when said displaced or overdimensioned thread peak engages with the created female thread. A fixture set for creating a strain is also provided, the set comprising a fixture and a separate thread maker. | 10-18-2012 |
20120315310 | BONE TISSUE IMPLANT COMPRISING LITHIUM IONS - The present invention is based on that local administration of lithium ions in bone tissue has been found to improve the bone formation and bone mass upon implantation of a bone tissue implant in said bone tissue. In particular, the invention relates to a bone tissue implant having an implant surface covered by an oxide layer comprising lithium ions and a method for the manufacture thereof. A blasting powder comprising lithium ions, a method for locally increasing bone formation, and the use of lithium ions or a salt thereof for manufacturing a pharmaceutical composition for locally increasing bone formation are also provided by the present invention. | 12-13-2012 |
20130165020 | BLASTING METALLIC IMPLANTS WITH TITANIUM OXIDE - A method of processing a surface of a metallic implant, such as a dental implant, to provide a desirable surface roughness, comprising subjecting the metallic implant to blasting with particles of one or more titanium oxides, including at least one non-stoichiometric titanium oxide, the particles having a compact morphology and a particle size in the range of from 1 to 300 μm. The resulting implant surface showed unexpectedly high retention strength after implantation in bone. | 06-27-2013 |
