  • Publication number: 20220313399
    Abstract: The present disclosure provides a dental screw (10) for fixing dental components (1, 2) to each other, the dental screw having a proximal end (11), a distal end (12), and a longitudinal axis (LS), wherein the dental screw further comprises a screw head (13) including a tool engaging interface (20) for engaging a fastening tool (30) at the proximal end and distally to the screw head a screw shank (14), the screw shank comprising a torque limiting portion (15) and distally to the torque limiting portion a threaded portion (16) for engaging a dental component (1, 2, 3), wherein the dental screw is configured to transfer a minimum torque from the tool engaging interface to the threaded portion of 26 Ncm and the torque limiting portion is configured to limit the torque transferable to a maximum torque for preventing damage to the threaded portion. The disclosure also provides a dental fastening tool, a dental fastening set, and a dental support set.

  • Patent number: 11246685
    Abstract: The present invention relates to a connection assembly for attaching a dental component to a dental implant, a dental component for the connection assembly and a method to use the connection assembly. The connection assembly (100; 1100; 2100; 3100) is removably attachable to the dental implant (10; 1010; 2010; 3010), preferably with the dental component (20; 1020; 2020; 3020) attached to the connection assembly, and a dental component is attachable to the connection assembly in a pre-fastened state or a fastened state. The pre-fastened state, when the connection assembly is attached to the dental implant, the connection assembly allows for adjustment of a relative position and/or orientation between the dental component and the dental implant.

  • Patent number: 11219510
    Abstract: The disclosure of the present application relates to a healing abutment system and its use. The abutment system can include a base part adapted to be coupled to a dental implant via an abutment screw and a healing cap that can be coupled to the base part by a further screw. The healing cap can include features that can be scanned by an intra-oral scanning system or transferred to a physical impression to convey information regarding the position and orientation of the base part.

  • Publication number: 20190282340
    Abstract: The present invention provides a handling tool (60, 160) for a dental component (20, 40) having a distal end (69, 169), a proximal end (68, 168) and a longitudinal axis L. Further, the handling tool (60, 160) comprises a grip (63, 163) at the proximal end, a shaft (65, 165) located distally of the grip (63, 163) with an engagement section (61, 161) for engaging an engagement feature (32, 132) of a fastening element (30, 130) and a retaining section (62, 162) for retaining the dental component (20, 40) to be fastened by the fastening element (30, 130). The retaining section of the handling tool is configured to allow for a rotation relative to the dental component.

  • Publication number: 20190247150
    Abstract: The present invention provides a dental component (20; 120) forming the basis for at least a part of a prosthetic dental arch and comprising at least two subcomponents (21, 22; 121, 122) and a connecting device (30; 130) for compensating an offset in position and/or orientation between the subcomponents (21, 22; 121, 122). Each subcomponent (21, 22; 121, 122) includes a mounting portion (25, 26; 125, 126) for mounting the dental component (20; 120) on at least one dental implant or at least one dental implant analogue (11, 12; 111). The connecting device (30; 130) comprises a rotary compensation means (50, 60; 150, 160) that connects the two dental subcomponents (21, 22; 121, 122).

  • Publication number: 20190029779
    Abstract: The invention relates to a dental fitting (1, 1?, 101, 101?, 101?) attachable to a dental component (30), such as a dental implant. The dental fitting (1, 1?, 101, 101?, 101?) comprises a main body (2, 2?) and a retention element (4, 104, 104?, 104?) provided apically to the main body (2, 2?). The retention element (4, 104, 104?, 104?) comprises an attachment portion (6, 106, 106?, 106?) for attaching the dental fitting (1, 1?, 101, 101?, 101?) to the dental component (30). The retention element (4, 104, 104?, 104?) has a closed ring shape or an open ring shape in a cross-section perpendicular to the direction from the attachment portion (6, 106, 106?, 106?) towards a coronal end (8) of the main body (2, 2?). The attachment portion (6, 106, 106?, 106?) comprises at least one projection (10, 110, 110?, 110?) extending in one or more directions substantially perpendicular to the direction from the attachment portion (6, 106, 106?, 106?) towards the coronal end (8) of the main body (2, 2?).
