The spring-loaded snap fastener may include a metal coil having at least three turns disposed in a same plane. The spring-loaded snap fastener may secure the removable prosthesis to the implant by at least gripping a groove disposed at least a partially around an interface between the removable prosthesis and the implant.

A method of manufacturing an article comprising: (a) performing an additive manufacturing process to firm an article in an initial state, the article comprising mounting features and being supported during the additive manufacturing process by support structures; and (h) performing a second manufacturing process to transform the article into a second state, which second manufacturing process is a subtractive process comprising: (i) mounting, via the mounting features formed during the additive manufacturing process, the article in a holding device of a machine for operating on the article, with the support structures or at least remnants thereof remaining on the article, and (ii) with the article so mounted in the holding device, processing at least one feature on a surface of the article on which the support structures were provided to remove material on the at least one feature provided by the support structures.

A dental implant system includes an anchoring part of a ceramic material for anchoring in bone tissue, an abutment of ceramic material, and an abutment screw. The anchoring part has a recess that is open towards a coronal end for engagement of a fastening post of the abutment. The abutment has an opening that is continuous in the axial direction and into which the abutment screw can be inserted. The abutment screw is configured, for a fastening of the abutment to the anchoring part, to engage into an inner thread that is formed on the anchoring part in the recess or is present on an insert element that is inserted into the recess. The abutment screw has a screw head, and a shoulder, which is formed coronally and which together with the screw head forms a stop on inserting the screw into the opening, is present in the opening.

A dental implant system includes an anchoring part of a ceramic material and an insertion tool. The anchoring part includes an outer thread that defines an axis. The anchoring part has a recess for an engagement of a fastening post of an abutment as well as for an engagement of an insertion tool, the recess being open towards the coronal end. The recess has an inner structure region with an inner structure that forms an insertion geometry for interacting with a corresponding outer structure of the insertion tool, and the insertion tool has an engagement portion with the corresponding outer structure. The recess forms a support region coronally of the inner structure region, wherein a transition region with a surface which in the longitudinal section is concavely arcuate and/or conical is formed between the support region and the inner structure region.

A method of manufacturing an article including taking an article in an initial state formed using an additive manufacturing process, the article including at least one set of mounting features; performing a second manufacturing process to transform the article into a second state, which includes mounting, via the at least one set of mounting features, the article in a holding device of a machine for operating on the article, wherein the position and orientation of the article in three linear and three rotational degrees of freedom within the machine operating volume is known and defined by virtue of the interaction of the mounting features with the holding device, and processing at least one feature on the article. The at least one mounting feature includes kinematic mount features which engage with corresponding kinematic mount features on the holding device of the machine.

The invention relates to an anchoring element for a dental prosthetic arrangement, which anchoring element can be anchored in a jaw bone or implant in a first subregion (TB1) and is suitable for receiving or forming a dental prosthetic element (ZK) in a second subregion (TB2), wherein the anchoring element has, between the first subregion (TB1) and the second subregion (TB2), a radially projecting collar (KR) which at least partially encloses the circumference of the anchoring element, such that the region above the collar (KR) of the anchoring element is at least in part fully covered with a thermoplastic material. The invention further relates to a method for producing an abutment or implant, and to a method for producing a dental prosthetic arrangement using the abutment.

A tooth implant system is provided, comprising a fixture, protrusions, and an abutment. The fixture has a top opening portion, a bottom closed portion, an inner surface portion, an outer surface portion, and a central hole portion surrounded by the inner surface portion. The plurality of protrusions are provided on the inner surface portion of the fixture at locations of substantially same heights from the bottom closed portion and with even circumferential intervals, and each of the plurality of protrusions comprises a vertical stop and a bottom edge. The abutment comprises an upper cylindrical portion, a middle connecting portion extending from the top cylindrical portion, and a lower engaging portion extending from the middle connecting portion. The lower engaging portion of the abutment is configured to be received into the central hole portion surrounded by the protrusions and engage with the protrusions.

Provided are a dental implant abutment and a method of manufacturing the same, and more particularly, a dental implant abutment which forms an outer appearance of an artificial tooth, supports a porcelain prosthesis that is formed of a porcelain, and couples to and fixedly combines with a fixture. The dental implant abutment includes: a first part having a coupling structure that corresponds to an inner structure of the fixture, so that the first part couples to the fixture; a second part that extends upward from the first part and contacts gums; and a third part extending upward from the second part, having an outer circumferential surface which includes a side surface and a top surface, with a porcelain prosthesis attached to the outer circumferential surface, and including a shape in which a concave part, inwardly recessed, is formed on the side and a horizontal cross-sectional area increases in an upward direction from the concave part.

Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.
