Abstract
An implant intended to be at least partially implanted into a bone, the implant including an implant part having an endosseous surface. The endosseous surface includes at least one zone having a surface topography exhibiting an arithmetic mean peak curvature parameter (Spc) which is less than or equal to 1 μm−1, and a density of peaks parameter (Spd) greater than or equal to 0.020 μm−2.

A method for manufacturing an implant intended to be at least partially implanted into a bone by means of an implant part having an endosseous surface, wherein said endosseous surface comprises at least one zone having a surface topography exhibiting:
- an arithmetic mean peak curvature parameter (Spc) less than or equal to 1 μm−1,
- a density of peaks parameter (Spd) greater than or equal to 0.020 μm−2,
- the method comprising the following successive steps:
- a) supplying an implant body comprising an endosseous surface intended to be implanted into a bone,
- b) supplying a solution of an organic material in a solvent, said solution containing a particulate material in suspension,
- c) applying the solution to a zone of the endosseous surface of the implant body,
- d) evaporating the solvent,
- e) heating the implant body to a treatment temperature, the treatment temperature and duration being chosen to be high enough to eliminate the organic material and not high enough to cause the particulate material and the material constituting the implant body to melt.
