Bio-functionalised implant part

A prosthetic abutment (2), configured for use in association with a dental implant (4) which is itself configured to be fixed in a jaw, the dental implant having an internal bore, said abutment comprising:

• a distal portion (22, 32) configured for fixing into the implant, said distal portion being sized and shaped for insertion into the internal bore of the implant;
• an intermediate portion (23, 33) configured for attachment to epithelial and/or connective tissues of the jaw;
• and
• a proximal portion (24, 34) configured for fixing a prosthetic element to extend from a proximal end (21) of the abutment,
• wherein the intermediate portion is located between the proximal portion and the distal portion,
• wherein the abutment comprises at least two zones that have different surface structures,
• wherein the at least two zones comprise a first zone situated in the intermediate portion (23, 33), and
• wherein a first surface structure of the first zone:
• is ordered and repetitive,
• is adapted to promote the growth of the epithelial tissue and attachment of the epithelial tissue to the abutment, and
• comprises micro-columns covered by engravings which form ripples.

A healing screw (3), configured for use in association with a dental implant (4) which is itself configured to be fixed in a jaw, the dental implant having an internal bore, said healing screw comprising:

• a distal portion (22, 32) configured for fixing into the implant, said distal portion being sized and shaped for insertion into the internal bore of the implant and having fixing means integral with the screw which are designed for cooperation with a zone of corresponding shape in the internal bore of the implant;
• an intermediate portion (23, 33) configured for attachment to epithelial and/or connective tissues of the jaw;
• and
• a proximal portion (24, 34),
• wherein the intermediate portion is located between the proximal portion and the distal portion,
• wherein the healing screw comprises at least two zones that have different surface structures,
• wherein the at least two zones comprise a first zone situated in the intermediate portion (23, 33), and
• wherein a first surface structure of the first zone:
• is ordered and repetitive,
• is adapted to promote the growth of the epithelial tissue and attachment of the epithelial tissue to the healing screw, and
• comprises micro-columns covered by engravings which form ripples.
