The implant frustoconical cavity (2) of the dental implant (1) is a through hole.

A dental abutment comprising a cylindrical abutment body and a tubular reconstruction element support; the abutment body is couplable to a dental implant and comprises a flat support end, the reconstruction element support has a proximal anchoring head portion configured with at least one slot, and a distal seat end bearing flush against the flat support end of the abutment body, said reconstruction element support is further configured with an axially extending through-going head bore, whereby the reconstruction element support is coupled to the abutment body by a manipulating fastener extending through the bore, and wherein axial fastening the fastener entails radial expansion of the anchoring head.

The invention relates to a dental prosthesis production device and method of manufacturing a dental prosthesis in which the dental prosthesis has an implant (40) and an abutment (10) which has a shape that is compatible with the implant (40) and on or to which abutment a dental structure (28) that is made of a dental material, in particular ceramic and/or plastic, and produced with the aid of a CAM process using rapid prototyping or compression molding technology can be secured. The abutment is mounted on the implant (40) via a releasable connection, in particular a screw connection (44), having an anti-rotation mechanism (50), and an anti-rotation device (groove 22) is formed between the abutment (10) and the dental structure (28). A selection device (66) is provided for abutments, said selection device allowing a selection of the abutment (10) for producing the dental prosthesis, optionally after reducing the abutment height to a specified value in a patient-specific manner, and a machining tool, in particular a milling cutter, or a CAM device is provided for shortening the abutment (10).

The disclosure relates to an assembly including a superstructure support that supports a superstructure, an implant body having an inner thread, and a threaded bolt. The superstructure support and the implant body are secured against rotation relative to one other. An inner thread is arranged in the cavity of the superstructure support, in the region of said cavity facing the implant body. The threaded bolt has two outer threads arranged one behind the other, with or without a spacing between them, the first of which is an outer thread for driving and the second is an outer thread for clamping. The two outer threads have different pitches. The present invention improves an assembly interface between a superstructure support and an implant body, such that the superstructure is securely supported, with simple pre-assembly and final assembly.

A dental implant assembly comprises, a base member which is rotatably insertable into a jaw-bone. The base member may be defined by a collar portion, a mid-portion and an apical region. The base member in entirety may be configured with a tapered configuration right from the mid-portion to the apical region. Further, the base member is defined with a plurality of threaded profiles on an outer surface. A first thread profile is defined on the collar portion. A second thread profile, defined on the mid-portion and a third thread profile, defined on the apical region. The third thread profile is configured to cut into the jaw-bone during insertion to anchor the base member. As the third thread profile cuts in to the jaw bone, the second thread profile forms a threaded hole within the drilled hole in order to securely anchor the base member within the jaw bone.

A cementless type dental implant includes: an abutment having vertical slits spaced apart from each other around an upper portion thereof, and having elastic coupling protrusions disposed between the vertical slits and radially providing elasticity; a crown cap having a coupling portion formed at a lower portion therein so that the upper portion of the abutment is inserted therein, having a screw hole formed at an upper portion therein, having a coupling step formed at a center therein to couple the elastic coupling protrusions of the abutment, and having a crown integrally formed outside; and an abutment screw inserted and fastened in a screw insertion hole of the abutment and having a protrusion pressing portion formed at an upper end thereof and pushing the elastic coupling protrusions radially outward when being fastened such that the elastic coupling protrusions are coupled inside the coupling step of the crown cap.

An implantation system has an implant body, an add-on element, and a connection element. The implant body has a connection inner profile or a connection outer profile; which cooperates with a connection outer profile or with a connection inner profile of the add-on element. The add-on element is connectable to the implant body in a rotationally-fixed manner. The connection element is screwable through an aperture of the add-on element into a thread of the implant body in order to detachably connect the add-on element to the implant body. The disclosure also describes an add-on element for an implantation system. The add-on element has a connection inner profile or a connection outer profile for producing a rotationally-fixed connection to a connection outer profile or to a connection inner profile of an implant body, and having an aperture for introducing a connection element.

A utility model pertains to the field of dental treatment components and was developed with the objective of better installation conditions, greater mechanical stability and greater comfort during use, when compared to similar ones in the current state of the art. It includes: an implant consisting of elongated and cylindrical body; conical apical region coated by a screw thread and with at least three helical chambers and semi-spherical end; and a cervical region defined by a smooth cervical surface, the elongated and cylindrical body including at least one longitudinal strip having a substantially smooth surface, said smooth longitudinal strip being located in the zygomatic implant cervical portion; the connection between the screw threads and the smooth longitudinal strip is made by a transition curvature, and the smooth longitudinal strip is aligned with one of the flat sides of the internal area with hexagonal cross section of the implant prosthetic interface.

The invention relates to an implant for osseointegration into a jaw bone, having a receiving opening one section of which is designed as an inner polygon, and at its distal end, the implant includes an indexing that reproduces the geometry of the inner polygon.

A dental abutment, is disclosed, comprising first and second units, the first unit is removably connectible to an unclaimed in vivo dental implant by a connective element pivotable with respect to both units. Said first unit having a distal end contoured in match with an end contour of the dental implant, and a proximal end contoured in match with a distal end contour of the second unit, said proximal end comprises a supportive surface adapted to lie in contact with a contact surface located on the distal end of the second unit. The supportive surface and the contact surface may be planner (uncurved) surfaces, and the connective means between the units may be other than and unattached to the connective element which connects the first unit to an intended implant. A tolerated connective assembly bar may be secured to the disclosed abutment, for retaining a dental milled by a plurality of the disclosed dental abutment.
