One-piece dental device and method to manufacture the same

Abstract

A dental device, in particular a one-piece dental implant, comprising an outer body made of metal; and an inner body made of plastic or composite, wherein the inner body comprises a core perfectly fitting into a cavity of the outer body, and a method for manufacturing a dental device, in particular a one-piece dental implant, comprising the following steps in any order: manufacturing an outer body of metal; and manufacturing an inner body of plastic or composite material; wherein the inner body comprises a core manufactured within a cavity of the outer body.

1 . A dental device, in particular a one-piece dental implant, comprising an outer body made of metal; and an inner body made of plastic or composite material, wherein the inner body comprises a core perfectly fitting into a cavity of the outer body. 
   
   
       2 . The dental device of  claim 1 , wherein the inner body further comprises a collar coronally of the core and an abutment coronally of the collar. 
   
   
       3 . The dental implant of  claim 1 , further comprising a metal or ceramic inner sleeve fixed to a hollow portion of the inner body, the inner sleeve being adapted for providing fixing means to a cap, a crown or the like. 
   
   
       4 . The dental implant of  claim 3 , further comprising one or more of the following means: snap coupling, press fitting, adhesive coupling means, lock engagement and warm shrinking for fixing the inner sleeve to the hollow portion of the inner body. 
   
   
       5 . The dental implant of  claim 3 , wherein the inner sleeve is provided by means of metal injection molding. 
   
   
       6 . The dental device of  claim 1 , wherein the outer body is provided by means of metal injection molding and the inner body is provided by means of plastic injection molding or by means of composite flow molding. 
   
   
       7 . The dental device  claim 1 , wherein the outer body is provided by means of lathe processing, milling or drilling, and the inner body is provided by means of plastic injection molding or by means of composite flow molding. 
   
   
       8 . The dental implant of  claim 1 , wherein the metal is chosen among titanium or a titanium alloy, wherein the plastic material is chosen from a group including PEEK (Polyetheretherketone), PPSU (Polyphenylensulfone), PES (Polyethersulfone) or combinations thereof; or wherein the composite material is chosen from one of said polymers and a fiber including Al 2 O 3  or SiO 2  or ZrO 2 . 
   
   
       9 . The dental implant of  claim 1 , wherein the implant surface is topographically or chemically modified by sandblasting, acid-etching or combination thereof, and/or plasma spraying, and/or growth factor adsorption, and/or peptide adsorption and/or protein adsorption, and/or amino acid adsorption, and wherein the modification of the implant surface is carried out at a soft tissue and/or bone tissue apposition surface. 
   
   
       10 . The dental implant of  claim 6 , wherein the inner profile of the cavity of the outer body is complementary to the outer profile of the inner body, and wherein the respective profiles are rounded, such as to decrease tension between the inner and the outer bodies and/or such that to provide for an anti-rotation lock between the two bodies. 
   
   
       11 . The dental implant of  claim 6 , wherein the inner profile of the cavity outer body is complementary to the outer profile of the inner body, and wherein the respective profiles are conically shaped. 
   
   
       12 . The dental implant of  claim 1 , wherein the apical section of the outer body is provided with at least one venting orifice. 
   
   
       13 . A dental device, in particular a one-piece dental implant, comprising an outer body made of metal; and an inner body made of plastic or composite material, wherein the inner body comprises a core perfectly fitting into a cavity of the outer body, wherein the inner profile of the cavity of the outer body is complementary to the outer profile of the inner body, and wherein the respective profiles are rounded, such as to decrease tension between the inner and the outer bodies and/or such that to provide for an anti-rotation lock between the two bodies. 
   
   
       14 . The dental device of  claim 13 , wherein the outer body is provided by means of metal injection molding and the inner body is provided by means of plastic injection molding or by means of composite flow molding.
