The porous layer is disposed on the compact layer, and the porous layer is formed from a second material. The moldable medical membrane has a moldable temperature range. A melting point of the compact layer is within the moldable temperature range, and a melting point of the porous layer is higher than the moldable temperature range.

Dental assemblies for a mouth of a patient are provided. Contemplated dental assemblies can comprise an implant having an upper portion and a lower portion, wherein the upper portion comprises a threaded portion configured to screw into a threaded recess of an abutment, and wherein the lower portion comprises an angled platform and a threaded post extending from the platform, the threaded post configured for threaded engagement with bone or tissue in the mouth of the patient. In some aspects, the angled platform can be angled, for example, about 15 degrees, about 20 degrees, about 30 degrees, between 10-35 degrees, or between 15-30 degrees relative to a line that is orthogonal to a length of the implant.

A dental attachment assembly, comprising: an abutment member for attachment to a tooth root, implant, or adjacent tooth, the abutment member having an upper end, and an outer locating surface portion projecting downwardly from the upper end, the outer locating surface portion being positioned to project above a tissue level when the abutment member is secured in a tooth root or implant; a male member for attachment to the abutment member, the male member having an upper end comprising a swivel joint for swivel engagement within a cap in a recess in a dental appliance, and a continuous, unbroken skirt projecting from the upper end of the male member for engagement over the outer locating surface of the abutment member, the skirt having a rounded, convex outer surface, the male member being constructed from a rigid material.

The present invention comprises an apparatus for facilitating the acquisition of a scan during an intraoral scanning procedure using an intraoral scanner, including: an elongate body having an attachment portion configured to attach the elongate body with an implant in a patient's mouth, the implant having a longitudinal axis, whereby the elongate body is adapted to extend substantially perpendicular to the longitudinal axis of the implant when mounted to the implant; the elongate body having a substantially planar upper surface and one or more side walls extending downwardly away from the upper surface; wherein the upper surface and the one or more side walls are observable in a resulting scan when the intraoral scanner scans the apparatus in a direction perpendicular to the upper surface.

The invention extends to a kit including a plurality of items of the apparatus and to a method of performing an intraoral scanning procedure.

A dental attachment assembly is provided, including an abutment member and a male member. The abutment member may include an outer locating surface portion having at least two axially spaced retention portions having two generally rounded, annular projections. The male member for engagement over the outer locating surface of the abutment member may include an upper end and a continuous, unbroken skirt having a rounded, convex outer surface. The male member may be constructed from a rigid material and have at least two axially spaced, snap engaging formations on the inner surface of the skirt for snap engagement with the respective retention portions of the abutment member.

A dental assembly is provided, which includes an endosseous dental implant, a retention member, and a cap configured for securing in a dental appliance and engaging the retention member. The endosseous dental implant may have an external projection extending from the top of the first end portion for releasable engagement with an abutment member, wherein the abutment member has an external lower bevel portion. The retention member may have a first end and a continuous, unbroken skirt extending from the first end defining an inner surface for engagement over the outer locating surface of the abutment member, the retention member being constructed from a rigid material such that it provides a retentive force of about 10 to 75 pounds. The rigid material may include PEEK.

Dental assemblies comprising a dental appliance are provided herein. Contemplated dental appliances can comprise a first recess and a second recess, a first cap for securing in the first recess and a second cap for securing in the second recess, a first abutment member for attaching to a first tooth root, implant, or adjacent tooth, and a second abutment member for attaching to a second tooth root, implant, or adjacent tooth. A first retention member sized for engagement within the first cap may be provided, the first retention member having a first end and a continuous, unbroken skirt extending from the first end defining an inner surface for engagement over the outer locating surface of the first abutment member, and the retention member being constructed from a rigid material such that it provides a retentive force of about 10 to 75 pounds.

A fixed hybrid dental attachment assembly comprising an abutment member, a male member, and a cap are provided herein. The abutment member comprises an outer locating surface portion projecting downwardly from an upper end. The male member for attachment to the abutment member comprises an upper end for engagement within a cap in a recess in a dental appliance, and a continuous, unbroken skirt projecting from the upper end of the male member for engagement over the outer locating surface of the abutment member. The skirt may comprise a rounded, convex outer surface, and the male member may be constructed from a PEEK material.

A scanning body system for determining a positioning and orientation of a dental implant, including a base part, an interface, and a scanning part which has a three-dimensional scanning contour and is rigidly connected to the base part to form a scanning body, and a fastening screw, provided for fastening the scanning body in the dental implant. Provision is made that the base part and/or the fastening screw are provided with at least one mechanical retention arrangement, which holds the fastening screw securely in the scanning body after insertion into the scanning body through a passage of the scanning part.

Disclosed is a method of creating a digital abutment design of a customized dental abutment, the including comprising: obtaining a bone scan comprising a digital representation of at least a part of a patient's jaw including the surface of the jawbone; and designing the digital abutment design of the customized dental abutment; wherein the design of the digital abutment design is at least partly based on fulfilling a set of predefined design criteria including the relationship between the digital representation of the jawbone and the digital abutment design.
