  • Publication number: 20200261188
    Abstract: A process for the preparation of a topography for improved fibrin network formation and cell mineralization on at least a portion of a dental implant made of a binary titanium-zirconium alloy, the portion being destined to be embedded in a patient's jawbone and to be in contact with the jawbone via a bone-contacting surface, the process includes the subsequent steps of a) subjecting the bone-contacting surface of the dental implant to a sandblasting treatment, b) etching the sandblasted bone-contacting surface, and c) treating the sandblasted and etched bone-contacting surface with water or an aqueous solution for a duration of more than two days, during which nanostructures continuously grow on the bone-contacting surface, the nanostructures extending in at least two dimensions to 200 nm at most. The process is characterized in that the treatment of b) is carried out at a temperature from 40° C. to 60° C.

  • Publication number: 20120119420
    Abstract: A method of synthesising a nano metric composite which has a core and shell structure includes preparing isometric metal oxide cores with an average diameter of less than 100 nm by a growth process via a liquid route. A double surfactant method is used which includes a first surfactant to obtain mono dispersal of the metal oxide cores and then a second surfactant to prepare the surface of the metal oxide cores, thereafter grafting a shell on each core.

  • Publication number: 20090256285
    Abstract: A method of producing a ceramic component includes dispersing an alpha-alumina nanopowder whose diameter is above 100 nm in water, using 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTC) or 4,5-Dihydroxy-m-benzenedisulfonic Acid, Disodium Salt (Tiron™) as dispersant. The pH is shifted towards the isoelectric point (IEP) by adding a mixture of acetic anhydride and ethylene glycol or polyethylene glycol, drying in a controlled atmosphere (humidity, temperature) and post compacting using cold isostatic pressing and sintering the three-dimensional structure thus formed.

  • Publication number: 20050027302
    Abstract: A head component for use in a prosthetic joint such as a hip joint. The head has a body adapted to engage a natural acetabulum or a prosthetic acetabular cup component. The head has a recess with a resilient sleeve located therein adapted to engage the trunnion of a prosthetic stem component with which it is to be used. The sleeve material is more deformable than the trunnion material and can deform under sufficient force to absorb any unevenness in the trunnion surface.

  • Patent number: 6783535
    Abstract: A targeting apparatus for use in performing endofemoral osteotomy surgery has a support element provided with a drill guide. The apparatus has a connector for securing a support element to the proximal end of a prosthesis to be implanted. The apparatus includes a proximal location element which is shaped to extend around the great trochanter and muscle of the femur in which the implant is to be located. An adjustor is provided for adjusting the angular position of the drill guide in relation to the femur about a proximal-distal axis.
