A multi-component dental implant system designed to improve oral hygiene. The dental implant system may comprise an implant body configured to be insertable into at least a portion of an individual's mouth, a primary or first abutment, a dental prosthesis engagement member, and a housing assembly. In use, the first abutment is designed to engage with and secure to the dental prosthesis engagement member. The housing is configured to secure to or cover the dental prosthesis engagement member. The dental implant system allows an individual to remove a prosthesis without the aid of any special tools or instruments.

A dental abutment coping or ring for securing a dental prosthesis to dental abutments. The coping or ring includes a body for insertion into a dental prosthesis, and a cavity or space sized to accept a head of the dental abutment. The interior surface of the cavity includes an interface region sized and shaped to accept the dental abutment in a retentive interface fit or a passive fit, depending on an angle of the interface surface. The exterior surface can have channels configured to contain a cement bonding the exterior surface to the dental prosthesis. A dental prosthesis system including the dental copings provides a retentive interference fit between the prosthesis and the dental abutments, even where the dental abutments are not parallel. A plurality of copings and abutments enables a retentive fit to varying degrees depending on the degree of interference fit in each coping and abutment.

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.

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).

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 dental implant system including a dental implant (1) and an associated implant analog (50), the implant extending along a longitudinal axis (L1) from an apical end (101) to a coronal end (102) and having an external surface for anchoring and osseointegrating in bone, a coronal end portion (105) having abutment connection geometry for cooperating with an abutment which can be seated in one or more defined positions on the implant, the abutment connection geometry having a coronally facing abutment contact surface (128) which extends around the full circumference of the implant, and in use directly contacts the abutment and provides a stop defining the axial location of the abutment relative to the implant, the coronal end portion further having a coronally facing prosthesis contact surface (129) located radially beyond the abutment contact surface, the prosthesis contact surface being a continuous surface extending around the full circumference of the implant.

An implant body having a coronal end and an opposing apical end, an outer surface and a compartment extending therein from a coronal end toward the apical end, the implant body including a gap between the compartment or spherical head portion and the outer surface.

A device and a system for forming a releasable connection between a dental implant abutment and prosthetic restoration, and in particular to such a device and system that is configured for use in situations where the inter-occlusal space is very limited, the device having a female connection device having a hollow tubular body featuring an open lumen.

Dental implant comprising an implant body having on an outer side an external thread for fastening the dental implant to a jaw bone and having an opening extending along a longitudinal axis of the dental implant. The opening comprises an internal thread for fastening a superstructure to the dental implant. The implant body further comprises an interface for fastening the superstructure to the dental implant, which interface is arranged at a front end of the implant body. The dental implant further comprises an anti-rotation element which is configured to prevent rotation of the superstructure around the longitudinal axis relative to the dental implant, wherein the anti-rotation element is configured as a component separate from the implant body, which is attached to the implant body in an area of the interface.

The present invention relates to a connection between a post part provided for being screwed into the jawbone and an associated superstructure part to which a dental prosthesis can be fastened. The connection between the post part and the superstructure part has a rotational self-centering action, wherein at least one of the surfaces provided for this purpose has a friction-minimizing modification and/or coating.
