A dental implant screw for holding an abutment on a dental implant includes a head and a shaft. A proximal end of the shaft is coupled to the head. The shaft includes a threaded section, an outwardly tapered section leading into a recessed section, and a stop section directly between the outwardly tapered section and the recessed section. The recessed section is directly between the head and the stop section. The threaded section is directly adjacent a distal end of the shaft and is configured to engage threads of an internally threaded bore in the dental implant to hold the abutment on the dental implant.

A dental implant assembly (200) configured to be positioned in an osteotomy cavity formed in a patient's jawbone. Abase member (204) of the implant is positioned into the cavity. The base member serves as a platform to secure an abutment member (202) of the implant that in turn receives a dental restoration, such as a crown or denture.

A substantially tubular intermediate attachment part with a first through-hole for attaching a screw-retained dental prosthetic component or a dental tool to a dental implant or to a dental implant analog, extending along a first longitudinal axis between a first end and a second end. Each end is provided with a set of longitudinal fins intended for snap-fitting into the dental prosthetic component or into the dental tool on the one hand and into the dental implant on the other hand.

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.

The present invention relates to a dental implant and a replacement ring. The dental implant has an insertion portion for anchoring in a jaw bone. The replacement ring serves for replacing a subtractively removable annular material region in a coronal region of the insertion portion. The shape of the replacement ring is inscribable into the shape of the dental implant in the coronal region at least to some extent such that an inner lateral surface of the replacement ring lies within the shape of the dental implant.

A dental restoration system is disclosed. A dental restoration system includes an implant, retention component, dental component and driver tool. The retention component is sealable in a retention chamber of the implant. The retention component includes a driver section for interfacing with a driving head of the driver tool and a dental component engagement section with a threaded surface. The dental component includes a retention component interface surface with threads. The dental component engages the retention component via the threaded surface interlocking with the threads of the retention component interface surface when the dental component is inserted in the implant. The driver tool is used to rotate the retention component to engage the dental component apically. The retention component contacts the retention component wall and the dental component contacts an annular shoulder of the implant when the dental component is fully attached to the implant.

Apparatus including a seal (100) is provided for use with a dental implant (200). The seal has a cross-section defining a high-load bearing portion (320) and a low-load bearing portion (340) angled in relation to each other, the high-load bearing portion being configured to apply a pressure that is greater than a pressure applied by the low-load bearing portion. A surface area of the high-load bearing portion is smaller than a surface area of the low-load bearing portion. Other applications are also described.

An abutment for a dental implant system includes a main body extending along a longitudinal axis from a first end to a second end. The main body includes a peripheral side surface having a continuously-flared profile from the first end to the second end. The abutment further includes one or more impression features formed at the second end of the main body and one or more scan features formed at the second end of the main body. A clocking element is formed at the first end of the main body. The abutment includes a matte material surface and is configured for use as an impression transfer and as a scan body in a dental implant operation.

A dental connection assembly for connecting an artificial denture to a jaw comprises a retention insert, an abutment structure, a fixation screw and an intermediate insert. The retention insert has a retention end portion and a retention skirt portion forming a retention cavity. The retention insert and the abutment structure are configured to be snap-fit connected by the retention cavity of the retention insert receiving a male member of the abutment structure. The abutment structure has a screw socket which opens at the male member and which corresponds to the fixation screw such that the fixation screw is axially movable into the screw socket by screwing the fixation screw into the screw socket. An intermediate skirt portion of the intermediate insert forms a female recess dimensioned to receive the male member. A flange portion of the intermediate skirt outwardly extends from a second axial end of the intermediate skirt portion.

An implant abutment is disclosed. An implant abutment for connecting a fixture and an artificial prosthesis, according to one embodiment of the present invention, comprises: an abutment lower part coupled to the fixture; an abutment upper part coupled to the artificial prosthesis, wherein the abutment lower part and the abutment upper part are integrally formed or separately coupled; and a small-movement part, which is interposed between the abutment upper part and the abutment lower part or disposed on a portion or all of the abutment upper part.
