The invention concerns a supra structure abutment holder for holding an arrangement of supra structure 16 and abutment 14, with a clamping device 12 for the arrangement, and is characterized in that clamping device 12 is adjustable in its height relative to an auxiliary device 26, in particular via threads.

A tooth implant system has an upper abutment, a lower abutment, a crown, and an elastic member securely placed between the upper abutment and the lower abutment providing softer and elastic, yet resilient, cushion between the upper abutment and the lower abutment. To better affix the elastic member within the tooth implant system, a ring lock may be used, securely placed in a ring-lock groove located on the lower abutment section. An insertion of a screw deeper into the lower abutment receptacle pushes the ring lock-groove and the ring lock outwardly to force the elastic member against an inner chamber wall of the upper abutment and into the abutment groove to better securely affix the elastic member.

The present invention provides a dental implant including: a fixture and an abutment including a coupling leg, and the fixture and the abutment are elastically coupled with each other, the dental implant including: a fixture axial hole inner inclined surface in which an inner diameter of an axial hole is gradually and downwardly reduced from a predetermined position of an inner inclined surface of the fixture; a first coupling part formed with a coupling hole at a predetermined position of the fixture; and a first associated coupling part formed with a coupling protrusion complementarily coupled with the first coupling part, wherein when the first associated coupling part is separated from the first coupling part by rotating the abutment, the coupling protrusion upwardly pushes the abutment from the fixture by elastic repulsion with the axial hole inner inclined surface of the fixture, thus the abutment becomes separated from the fixture.

The invention relates to a dental prosthesis system that includes a ceramic implant for osseointegration in a jaw bone with a receiving opening for a connection screw and an abutment, preferably made of a ceramic, wherein the abutment can be secured in the receiving opening of the implant by the connection screw made of fiber-reinforced thermoplastic. A screw lock includes first interlocking elements and second interlocking elements, wherein the first interlocking elements are arranged on the connection screw and the second interlocking elements are arranged in the receiving opening of the implant and/or on the abutment. When tightening or releasing the connection screw in the implant, the first interlocking elements are elastically deformed in conjunction with the second interlocking elements.

The present application relates to a fitting for insertion into a dental implant in an insertion orientation defining a central insertion axis. The fitting includes at least one resilient spring member which extends from a body portion. It further includes an alignment feature for aligning the fitting relative to the dental implant about the insertion axis. The alignment feature extends distally beyond the distal end of the spring member.

A dental anchoring system for fastening prostheses having a male component, a female component which is coupled to the male component, and a connection element which is coupled to the female component and makes up the retaining element of the prosthesis configured to be joined to the connection element. The dental anchoring system is configured to achieve a self-adjustable fastening of the prosthesis which enables the mobility of prosthesis to be controlled when it is subjected to a load during the use thereof by a patient; and wherein the mobility is limited by a ring-shaped stop of the female component, when at least one portion of a ring-shaped plane of the connection element comes into contact with ring-shaped stop of the female component.

A ceramic dental prosthesis including an implant for osseointegration in a jaw bone with a receiving opening and an abutment having a through-hole for receiving a bolt. The bolt is produced from a fiber-reinforced thermoplastic and connects the abutment and the implant. The dental prosthesis system includes an anti-rotation feature formed by a first interlocking means arranged on a proximal end of the abutment and a second interlocking means arranged on a distal end of the implant. The first interlocking means engages in the second interlocking means, wherein the first and second interlocking means are arranged at a distance from one another such that the abutment can be tilted relative to the implant. The bolt runs in the through-hole of the abutment and the receiving opening. An interference fit is provided between the bolt and the receiving opening of the implant.

A dental assembly for vertical attachment of an implant to a dental abutment for restorative dental procedures is disclosed. The implant includes a cylindrical body having an interior bore formed between a distal end and a proximal end. An abutment interface is formed on the proximal end of the cylindrical body. The interface includes a radial annular interior surface and a flat annular stop surface circumferentially bordering the interior bore. The assembly also includes an abutment including a stem and a post coupled to the stem. An interior bore is formed through the stem and the post. The abutment includes an interface section between the post and the stem. The interface section may include an annular radially curved exterior surface proximate to the post. The radially curved exterior surface and the circular flat surface interfaces with the abutment interface of the dental implant.

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.

A dental implant assembly includes an implant, an abutment, and a fixing element. The implant is placed in the alveolar bone. The abutment is assembled to the implant and includes a tapered position-restricting part and an elastic pressing part. The tapered position-restricting part has an abutment fixing channel substantially matching the tapered position-restricting outer wall of the tapered position-restricting trench. The elastic pressing part includes the elastic pressing structures extended from the tapered position-restricting part. The fixing element includes the fixing head and the fixing rod extended from the fixing head. A tolerance allowable gap is formed between the abutment fixing channel and the fixing rod. As the abutment is assembled to the implant, the elastic pressing structures press against the position-restricting wall first to hinder the relative rotation therebetween; when an offset error exists, the tolerance allowable gap allows the fixing rod to penetrate the abutment fixing channel.
