Abstract
A dental implant assembly comprising an elongated inner body substantially resembling a tooth root (1-1) and an outer member for securing to a bone of a patient (1-2) having a heterogeneous porous structure adapted to provide bone growth, the inner body and the outer fixation member being formed in one piece, the fastening element being movable between a stored passive position and an extended active position (1-2).
Claims7
A method of manufacturing a dental implant assembly using additive manufacturing, said method comprising:
- using a three-dimensional computer model of the intended implant to control a selective laser melting (SLM) system that selectively melts layers of powders;
- said powders comprised of a mixture of nanometric particles of zirconia (or similar ceramics) and particles of micrometric titanium (or any other metal);
- and
- stacking layers of metal powders and/or non-metallic fused selectively by concentration of an energy source comprising a step of preparing the mobility of the fastener relative to the inner body until the three-dimensional computer model of the intended implant is finished so that said dental implant comprises:
- an elongated body;
- said elongated body substantially resembling a tooth root and an outer member for fixing a heterogeneous porous structure to a patient's bone structure adapted to provide bone growth;
- the outer member being comprised of heterogenous porous structure movable between a stored passive position and an extended active position;
- and
- wherein said body and said outer member are formed in one piece from the same material through an additive manufacturing process using only dry powder materials.
