A connection structure for a dental abutment is such that an embedded part of a dental base part to fit to an oral cavity side of an implant fixture embedded in a jawbone is inserted into and connected to an insertion hole of a dental cutting block part, wherein the dental cutting block part includes a first flat surface and a protrusion on an inner peripheral surface of the insertion hole, and wherein the dental base part includes, on an outer peripheral surface of the embedded part, a second flat surface that corresponds to the first flat surface.

A dental restoration method comprising a step of determining a positioning of a dental implant (60), integrated into a bone structure (62) of an individual, from the identification and positioning of a one-piece healing member (10), attached at one of the ends of same in the implant (60), the healing element (10) comprising a side surface (13) intended to be integrated into a gum in order to shape the gum during the healing of same, and an end surface (14), a part of the side surface (13) and of the end surface (14) forming an emergent surface, intended to remain outside the gum, that is asymmetrical relative to at least a perpendicular median plane.

A dental device having an abutment body including a substantially radial mark on its external part, the abutment body adapted, to be connected, to an implant by a connecting member, such that the substantially radial mark is distinguishable from the abutment body in an image taken by an imaging device when the implant and abutment are installed.

The disclosure relates to methods for attaching a dental implant surgical guide and a dental implant to a dental surgical site including: assembling an implant combination, positioning the dental implant surgical guide including a double open-ended guide cylinder at the dental surgical site; rotating the implant combination through the double open-ended guide channel; and attaching a cap comprising a hollow cylinder to the double open-ended guide channel so the rim of the implant mount body is sandwiched between the dental surgical guide and the cap. The disclosure further relates to a dental prosthesis apparatus including: an abutment; a dental implant; a dental implant surgical guide including a first and a second double open-ended guide cylinder connected by a support bar; an implant mount including a rim; and a cap operable to engage the dental implant surgical guide and sandwich the rim between the cap and the dental implant surgical guide.

Disclosed herein an implant system for a denture. The denture implant system includes: an abutment and a screw configured to connect the abutment to a denture. The abutment comprises: an apex portion configured to face the denture and have linear edges that are parallel at least in an intermediate area, a thread hole provided in one end area of the apex portion and configured to accommodate the screw, and a fixture hole which is spaced apart from the thread hole and is formed toward a fixture engagement portion under the apex portion.

A connector bridge configured to connect between two adjacent surgical guide foundation devices. The connector bridge may include a crossbar portion, two connector pins spaced apart from one another, and wherein the two connector pins extend outward from the crossbar portion in a generally perpendicular direction relative to the crossbar portion. The connector bridge may include a crossbar portion, two openings spaced apart from one another and formed through the crossbar portion, removable bridge pins, and wherein the removeable bridge pins may be configured to be inserted at least partially through the openings.

A dental prosthesis with a threaded crown on a post and core includes a dental implant, a post and core having a portion adapted to be inserted into the implant and another portion protruding from the implant, a screw and a crown, the implant being adapted to be fixed to a bone and the post and core being adapted to be fixed to the implant with a thread, the crown being fixed to the post and core with the screw, wherein the post and core provides a connection element between the implant and the crown, a separation area being provided between the area where the post and core is housed in the crown and the area where the post and core is housed in the implant, and wherein the portion of the post and core protruding from the implant does not feature a diameter increase.

In a dental implant (1) comprising a post part (2) which can be placed in a jaw bone and comprising 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 moulded 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. For this purpose, in accordance with the invention the cross-sections of the contact pin (8) integrally moulded on the structural part and of the shaped recess (10), associated with said contact pin, in the post part (2) each have a number of primary directions in which the radius in each case adopts a relative maximum value, the outer contour of the cross-section being selected in such a way that it is intersected at at most two points by any straight lines, and each point has only one tangent.

A dental implant having a substantially cylindrical shape with a longitudinal axis defining a longitudinal direction, including: a coronal section including a coronal end of the implant; a threaded region extending apically from the coronal section to an apical tip of the implant; and an internal blind bore for connection to a secondary part, including: a stabilizing section extending apically from the coronal end; and a drive and indexing section which extends apically from an apical end of the stabilizing section, which includes a plurality of connecting lobes having a concave shape and extending in the longitudinal direction, being interconnected by respective lobe linking areas, including: two convex sections extending in the longitudinal direction and adjacent to a respective connecting lobe; and a concave section extending in the longitudinal direction between the two convex sections. Further, a secondary part and an insertion tool of a configuration matching the dental implant.

A ceramic dental implant for implantation into a jaw bone extending from an apical end to a coronal end. The implant has a blind bore open towards the coronal end and extends towards the apical end along a central longitudinal axis. The blind bore includes a threaded section having a base surface where a thread protrudes radially inwards. The threaded section includes a main portion, wherein the maximum thread radius remains constant along the portion length and, adjacent to the main portion, a tapered portion where the base surface tapers radially inwards from the maximum thread radius to the minimum thread radius at the apical end of the tapered portion, the tapered portion extending over an axial length greater than the thread pitch, forming a tapered thread having gradual reduction in thread depth, the tapered thread extending over more than one thread turn.
