Abstract

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.

Claims (18)

1 . A dental assembly convertible between a patient-removable state and a non-patient-removable state by interchanging retention members, the dental assembly comprising:

an abutment comprising an outer locating surface and a threaded recess;

a non-patient-removable retention member having a first end and a first skirt extending from the first end defining a first inner surface configured to engage over the outer locating surface of the abutment to form a non-patient-removable engagement to the abutment based on a retentive force of 10 to 75 pounds to convert the dental assembly to a non-patient-removable state, wherein the non-patient-removable retention member comprises a rigid material configured to provide the retentive force of 10 to 75 pounds when the non-patient-removable engagement forms to convert the dental assembly to the non-patient-removable state;

an implant comprising an upper portion and a lower portion,

wherein the lower portion comprises an angled platform and a threaded post extending below the angled platform, the threaded post configured to engage with bone or tissue in the mouth of a patient based on the threaded post;

wherein the upper portion comprises a threaded portion extending above the angled platform, the threaded portion configured to screw into the threaded recess of the abutment,

wherein the angled platform is angled between 10-35 degrees relative to a line that is orthogonal to a length of the implant from a center of the angled platform to a tip of the threaded post; and

wherein the abutment is configured to engage with a patient-removable replacement retention member to form a patient-removable engagement to the patient-removable replacement retention member to convert the dental assembly to a patient-removable state based on a retentive force of less than 10 pounds, wherein the patient-removable replacement retention member comprises a resilient material more resilient than the rigid material to provide the retentive force of less than 10 pounds when the patient-removable engagement forms to convert the dental assembly to the patient-removable state, the patient-removable replacement retention member having a second end and a second skirt extending from the second end and defining a second inner surface for patient-removable engagement over the outer locating surface of the abutment, in place of the non-patient-removable retention member.

2 . The dental assembly of claim 1 , further comprising:

a cap configured for securing in a dental appliance and engaging the non-patient-removable retention member.

3 . The dental assembly of claim 1 , wherein the threaded post is angled relative to the threaded portion of the upper portion.

4 . The dental assembly of claim 3 , wherein the threaded post is angled 15 degrees relative to the threaded portion of the upper portion.

5 . The dental assembly of claim 3 , wherein the threaded post is angled 30 degrees relative to the threaded portion of the upper portion.

6 . The dental assembly of claim 3 , wherein the threaded post is angled 20 degrees relative to the threaded portion of the upper portion.

7 . The dental assembly of claim 1 , wherein the threaded post comprises a single lead thread or multiple lead threads.

8 . The dental assembly of claim 1 , wherein the threaded post comprises opposing axial cuts adapted for self-tapping into the bone or tissue.

9 . The dental assembly of claim 1 , wherein the implant has a maximum outside diameter between 1.5 mm and about 4.0 mm.

10 . The dental assembly of claim 1 , wherein the threaded post comprises two successive threads of different pitch.
