Abstract
Provided herein is an implant made of a biocompatible ceramic of synthetic origin obtained by additive manufacturing. The implant may include a dense portion featuring a material density by volume greater than 70%, and a porous portion connected to the dense portion by a connection zone. The porous portion may have an average macroporosity having a material density ranging from 30% to 70% by volume and cavities defining cavity sections, with a diameter ranging from 0.3 mm to 1.2 mm. The dense portion and the porous portion may define an external surface. The cavities may open onto the external surface.

An implant made of a biocompatible ceramic of synthetic origin obtained by additive manufacturing and comprising:
- a dense portion, with a material density by volume greater than 70%, and
- a porous portion connected to said dense portion by a connection zone, said porous portion comprising an average macroporosity characterized by:
- an average material density determined for the entire volume of said porous portion of between 30% and 70% by volume;
- cavities delimited at least partially by side walls defining cavity sections, said cavity sections each having an extension such that it is possible to fit each of said cavity sections in a circle having a diameter ranging from 0.3 mm to 1.2 mm;
- said dense portion and said porous portion define at least partially an external surface of the implant;
- said cavities open onto said external surface.
