A two part modelling aid for connection to a dental implant component including a hollow base part and a hollow angled part, each including a tubular side wall extending between apical and coronal ends. The base part side wall includes an anti-rotation section including a non-circular symmetric cross-section in a plane perpendicular to a longitudinal axis of the base part. The angled part side wall forms an apical portion that extends along a first axis and is sized and shaped to form a friction fit with the base part, and a coronal portion extending along a second axis non-coaxial to the first axis. When connected, a closed channel is formed extending from the base part to the angled part, and the first axis of the apical portion is coaxial to the longitudinal axis of the base part and the anti-rotation section is exposed on a base part surface.

An abutment is provided with a screw access hole and a slot in its sidewall adapted to allow a driver to access a screw in the screw access hole at an angle relative to a longitudinal axis of the screw. The abutment may include a screw seat and may be connected to an implant via a screw in the screw seat. A prosthesis, which may include a driver access channel that has a diameter less than the outer diameter of the drive portion of the screw, may be placed over the abutment. Methods of making a dental prosthesis and methods of attaching and removing the dental prosthesis from the implant are also disclosed.

One or more specific embodiments disclosed herein includes a dental apparatus comprising a prosthesis, an implant fixture, a multi-unit abutment comprising a clocked projection and a conic section, and an adjustable locking device. The adjustable locking device may comprise a washer, a first pyramidal element, plurality of expansion segments each comprising a plurality of bottom planar surfaces and a plurality of top planar surfaces, a second pyramidal element comprising a second plurality of angled planar surfaces and a convex upper surface, a central retaining screw that threadingly engages the multi-unit abutment, and an O-ring, wherein the O-ring engages each of the plurality of expansion segments.

Disclosed are a fixture for a dental implant and an implant system comprising the same. The implant system of the present inventive concept comprises: a first fixture having a first body part and a first continuous screw part which is formed in a spiral around the outer circumferential surface of the first body part and is formed continuously without a break; and a second fixture having a second body part that is identical to the first body part, and a second continuous screw part which is formed in a spiral around the outer circumferential surface of the second body part and which has an outer diameter that differs from that of the first continuous screw part. The present inventive concept allows implant operations to be carried out in a more straightforward fashion than hitherto since, even if initial fixture placement fails, a subsequent fixture can be placed straight away without any further drilling work.

A dental anchoring system configured to anchor a carrier element at an anchoring element, the dental anchoring system including the carrier element; the anchoring element; and a fastening bolt, wherein the anchoring element includes a receiving section configured to receive the carrier element and a threaded bore, wherein the carrier element is configured to directly or indirectly attach a dental superstructure element or a dental prosthesis and wherein the carrier element includes a support section configured to be supported at the receiving section of the anchoring element, wherein the carrier element is attachable at the anchoring element by a first anchoring type using the fastening bolt by receiving the support section of the carrier element at the receiving section of the anchoring element and threading the fastening bolt into the threaded bore of the anchoring element.

A dental implant assembly containing an integrally-formed universal abutment which has a top section, a bottom section integrally joined to the top section, and a passageway extending through these sections. The passageway is formed by different size bores, initially a larger size than decrease in size. The top section of the abutment has a cross-sectional shape substantially like a polygon; the shape is formed by alternating linear and arcuate walls joining to a bottom section having a cross-sectional shape substantially like a polygon.

An abutment for use with a dental implant. The abutment includes a connecting pin configured to be introduced into an associated receiving channel of the dental implant. The connecting pin includes a screw channel for a connecting screw for connecting the abutment to the dental implant. An inner diameter of the screw channel over its entire length up to an opening on an end face is at least as large as the diameter of a screw head of the connecting screw, and a plastically deformed retaining element is provided in order to support the connecting screw.

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.

The present disclosure describes technical solutions to various technical problems facing generation of an angulated screw channel for dental implant. An improved screw channel model may be generated based on various inputs. The inputs may include dental implant parameters such as a screw channel length and a variable height. The inputs may also include dental screw parameters associated with a dental screw type, such as a screwhead diameter and a screwhead height. Using these inputs, the improved angulated screw channel model may be generated. By generating a model based on these input parameters, the resulting screw channel model allows the dental screw to be inserted and secured while reducing or minimizing a screw hole size and a screw channel volume.

A dental implant adapted for implanting within a jaw bone, the implant comprising a horizontally-oriented body having a length extending in the mesial-distal direction of the jaw bone, the body having a threaded cavity dimensioned for receiving a prosthetic abutment, and wherein the cavity comprises an opening that is located wholly within a buccolingual width of the body.
