Patent number: 11419705Abstract: 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.Type: GrantFiled: September 27, 2018Date of Patent: August 23, 2022Assignee: STRAUMANN HOLDING AGInventors: Christophe Cueille, Simon Berner

Publication number: 20120119420Abstract: 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.Type: ApplicationFiled: June 11, 2007Publication date: May 17, 2012Inventors: Fabrice Rossignol, Thierry Chartier, Wen Zhang, Cecile Pagnoux, Christophe Cueille, Adrian Sun Wai

Publication number: 20090256285Abstract: 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.Type: ApplicationFiled: February 18, 2009Publication date: October 15, 2009Applicant: Howmedica Osteonics Corp.Inventors: Anne-laure Penard, Fabrice Rossignol, Thierry Chartier, Cecile Pagnoux, Matthew Murphy, Christophe Cueille, Gerard M. Insley

Publication number: 20050027302Abstract: 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.Type: ApplicationFiled: August 26, 2004Publication date: February 3, 2005Applicant: Benoist Girard SASInventors: Christophe Cueille, Patrick Raugel
