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.

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 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 dental attachment assembly and method anchors a dental appliance with an implant and has an abutment member attached to the implant, a retention member in releasable snap engagement with the abutment member, and a cap secured in a recess of the dental appliance and in releasable swivel engagement with the retention member to position and secure the dental appliance onto the implant. The cap includes a cavity with a rounded, concave inner surface which engages with the retention member, an interior top surface of the cavity with a concave recess extending radially along an outer periphery of the interior top surface of the cavity to allow for rotation of the retention member within the cap. A central portion of the interior top surface of the cavity surrounded by the concave recess therefore protrudes vertically into the cavity to minimize vertical displacement of the retention member as it rotates.

A combined assembly for dental prosthesis is provided, wherein the combined assembly includes a first joint member and a second joint member. The first joint member has a first body and a plurality of elastic hooks, and the elastic hooks are annularly arranged to connect one end of the first body, wherein a slot is disposed between the adjacent elastic hooks, and each of the hook has a top portion protruding outward. The second joint member has a second body, and the second body is provided with a joint hole, a side wall surface of which is provided with a ring groove, wherein the elastic hooks extend into the joint holes, and the top portions of the elastic hooks engage into the ring groove.

The invention relates to a dental model (1) for dental-technical modeling having a model base (2) and having a tooth stump (4) that can be removed from the model base (2), the model base (2) having a receiving cavity (3) for receiving the tooth stump (4), the tooth stump (4) having a preparation section (5), the preparation section (5) being designed for the prosthetic reconstruction of a tooth and the shaft (6) being designed for insertion along an insertion direction into the receiving cavity (3), the model base (2) and/or the shaft (6) having an elastic positioning element for positioning the tooth stump (4) relative to the model base (2).

In a shell for adapting a retention element to an anchoring element, and a method of forming a further retention element on an anchoring element including a shell, the shell has an internal cavity, the dimensions of which are matched to the external dimensions of the retention element and which is connectable to the retention element in an integral or form-fitting manner, and has an outer surface which is formed as a further retention element.

Mechanisms for securing an abutment, removable prosthesis, and/or a fixed prosthesis to an implant without screws or cement are provided. At least a portion of an abutment and/or a fixed prosthesis may be formed from a resilient material to enable the abutment and/or the fixed prosthesis to be secured to secured to the implant without screws or cement. Alternatively, a removable prosthesis may include a spring-loaded snap fastener for securing the removable prosthesis to an implant without screws or cement. 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.

The invention relates to an adapter (1, 1′) for attaching a dental superstructure (50) to a dental implant (30). The adapter (1, 1′) comprises a coronal attachment portion (2, 2′) for attaching the adapter (1, 1′) to the dental superstructure (50), an apical attachment portion (4) for attaching the adapter (1, 1′) to the dental implant (30) and an intermediate portion (6) arranged between the coronal attachment portion (2, 2′) and the apical attachment portion (4). The apical attachment portion (4) is a protrusion defining an apical end portion of the adapter (1, 1′) and configured to be received in a corresponding recess (32) of the dental implant (30). The protrusion is rotationally symmetric, so that the adapter (1, 1′) is rotatable relative to the dental implant (30) in the state of attachment of the adapter (1, 1′) to the dental implant (30). Further, the invention relates to a dental assembly comprising the dental superstructure (50) and at least one such adapter (1, 1′).
