A substantially tubular intermediate attachment part with a first through-hole for attaching a screw-retained dental prosthetic component or a dental tool to a dental implant or to a dental implant analog, extending along a first longitudinal axis between a first end and a second end. Each end is provided with a set of longitudinal fins intended for snap-fitting into the dental prosthetic component or into the dental tool on the one hand and into the dental implant on the other hand.

A coupling element for dentistry applications having a tubular body which forms an internal duct that is open outward at respective ends of the body. A first end forms a first inlet for the insertion in the duct of the head of a pin which can be coupled directly or indirectly to a maxillary bone tissue. The first end has a recess provided along the edge of the first inlet and forms a guiding portion for the insertion of the head of the pin; along a segment of the duct which is contiguous to the first inlet there is a protrusion which is substantially aligned longitudinally with the recess, for contrasting the accidental rotation of a ring provided with a respective discontinuity, which can be arranged in the segment in order to lock the head of the pin.

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.

Disclosed is a dental implant abutment having a function of buffering occlusal force transmitted through a prosthesis and configured to be elastically coupled to the prosthesis without using an adhesive. A prosthesis fastening protrusion protrudes outward from an outer surface of an upper portion thereof on which a prosthesis is mounted. The diameter of the prosthesis fastening protrusion being greater than the diameter of a portion located directly therebelow. Indentations divide the upper portion of the abutment into a plurality of sections. The indentations continuously extend downward a predetermined length from a top end surface of the abutment. A predetermined lengthwise portion of each of the indentations has a spiral or oblique shape.

A medical adaptor generally featuring an adaptor body extending from a fitment end towards a perch. The adaptor further includes a fitment extending away from the fitment end, and a mortar extending away and integral with the fitment, to terminate at the perch. The adaptor also features a shrinkable collet including a collet face and a collet hole extended from a collet hole towards a collet tail. A collet bolt is threaded into the collet hole such that collet is avoided from getting shrunk and is locked at a desired angular position.

The invention relates to an abutment (100), in particular for dental interventions in assisted surgery, comprising: —a first element (1), comprising a lower cylindrical element (2) and a semi-spherical element (3) integral above with said cylindrical element (2), divided into a plurality of segments, held together by an outer element (4), in the transition zone between said lower cylindrical element (2) and said semi-spherical element (3) there being provided, internally, a shoulder (7), said semi-spherical element comprising a thread (5), ending at said shoulder (7), in which a centrally perforated screw (6) is coupled, a plurality of steps or protrusions (8) being provided on said lower cylindrical element (2); —a second element (10), comprising a first upper cylindrical element (11), which inserts inside said cylindrical element (2) of said first element (1) and equipped externally with a plurality of steps or protrusions (12), which are able to move vertically with respect to staid plurality of steps or protrusions (8) provided on said cylindrical element (2), and a lower semi-spherical element (13); and —a third semi-spherical element (16), divided into a plurality of segments, and ending with coupling means (14) with a dental implant (15).

Dental device including a base defining a main axis and including first and second portions, one configured to be constrained on a user's osseous portion, the other to be constrained to one or more artificial teeth, constraint element a constraint configuration wherein the first and the second portions are mutually constrained and a rest configuration wherein the first and second portions are separable. The constraint element including one wedge slider movable along the main axis to determine rest and the constraint configurations. A movable element at least partially counter-shaped to the slider and expandible radially relative to the main axis. An obstacle to interfere with the movable element when the constraint element is in constraint configuration to block mutual translation of the portions along the main axis. The cursor and the movable element arranged on the first portion. The obstacle is arranged on the second portion.

An abutment arrangement for connecting a dental restoration, having a post body and a screw element, to a dental implant is disclosed. The post body has an axial passage with a head socket and a press section. The screw element has a head section and a thread section. The screw element may be arranged in the post body passage so that the head section is positioned in the head socket abutting the press section, and the screw element extends through an occlusal aperture. When the screw element is arranged in the post body passage, a first locking section of the screw element is positioned adjacent to a second locking section of a mounting portion of the post body, with the first and second locking sections being configured to plastically deform the screw element and/or the post body such that the post body mounting portion is locked in an expanded position.

A dental restoration system is disclosed. A dental restoration system includes an implant, retention component, dental component and driver tool. The retention component is sealable in a retention chamber of the implant. The retention component includes a driver section for interfacing with a driving head of the driver tool and a dental component engagement section with a threaded surface. The dental component includes a retention component interface surface with threads. The dental component engages the retention component via the threaded surface interlocking with the threads of the retention component interface surface when the dental component is inserted in the implant. The driver tool is used to rotate the retention component to engage the dental component apically. The retention component contacts the retention component wall and the dental component contacts an annular shoulder of the implant when the dental component is fully attached to the implant.

Disclosed herein is a dental implant (1) having a post part (2) which can be placed in a jaw bone and having a structural part (4) associated with said post part, to which structural part a denture piece can be attached, the structural part comprising an integrally molded contact pin (8) which can be placed in an associated shaped recess (10) in the post part (2) with a positive fit, it is to be possible on the one hand to suitably index the implant in a simple and reliable manner, on the other hand a particularly high level of mechanical stability against rotation being ensured, even with an overall height which is kept low.
