ANTIMICROBIAL PROSTHETIC DENTAL ELEMENT

Abstract

Prosthetic dental element is obtained by machining a rod of composite material including fibres embedded in a matrix containing resin. The matrix also contains at least one agent with an antimicrobial effect at a concentration between 0.05 and 30% by weight of the prosthetic element. The agent is in powder form.

Description

Claims

1/ Prosthetic dental element comprising a machined rod of composite material including fibres embedded in a matrix containing resin, wherein the matrix also contains at least one agent with an antimicrobial effect at a concentration between 0.05 and 30% by weight of the prosthetic element, said agent being in powder form.

2/ Prosthetic element as claimed in claim 1, wherein the at least one agent with an antimicrobial effect accounts for 2 to 10% by weight of the prosthetic element.

3/ Prosthetic element as claimed in claim 2, wherein the at least one agent with an antimicrobial effect is selected from the group consisting of zinc oxide, copper oxide and silver oxide.

4/ Prosthetic element as claimed in claim 1, wherein a median diameter D50 of the the at least one agent with an antimicrobial effect has a value of less than 10 μm.

5/ Prosthetic element as claimed in claim 1, wherein particles of the at least one agent with an antimicrobial effect have a nanometric size between 30 and 80 nm.

6/ Prosthetic element as claimed in claim 1, wherein the matrix accounts for 20 to 45% by weight of the prosthetic element.

7/ Prosthetic element as claimed in claim 1, wherein the prosthetic element comprises a post, a bridge reinforcement or an implant abutment.

8/ Prosthetic element as claimed in claim 4, wherein the median diameter D50 of the at least one agent with an antimicrobial effect has a value of less than 5 μm.

9/ Prosthetic element as claimed in claim 4, wherein the median diameter D50 of the at least one agent with an antimicrobial effect has a value of approximately 1 μm.
