A dental implant includes a generally cylindrical body, an interior bore, and a non-rotational feature. The generally cylindrical body has a main-central axis and is formed from cold-worked, high strength, commercially pure titanium having an ultimate tensile strength of at least about 900 MPa. The generally cylindrical body has a proximal portion and an opposing distal portion for anchoring the dental implant in bone of a patient. The interior bore is formed in the generally cylindrical body and has (i) a bore-central axis and (ii) a threaded portion for receiving a screw that is configured to removable hold an abutment in engagement with the dental implant. The non-rotational feature is configured to engage the abutment in a non-rotational fashion.

A tooth implant system is provided, comprising a fixture, protrusions, and an abutment. The fixture has a top opening portion, a bottom closed portion, an inner surface portion, an outer surface portion, and a central hole portion surrounded by the inner surface portion. The plurality of protrusions are provided on the inner surface portion of the fixture at locations of substantially same heights from the bottom closed portion and with even circumferential intervals, and each of the plurality of protrusions comprises a vertical stop and a bottom edge. The abutment comprises an upper cylindrical portion, a middle connecting portion extending from the top cylindrical portion, and a lower engaging portion extending from the middle connecting portion. The lower engaging portion of the abutment is configured to be received into the central hole portion surrounded by the protrusions and engage with the protrusions.

A system including a method and associated structures creates efficiencies in the manufacture of prosthetic tooth support frameworks. Pre-manufactured teeth with matching internal keys are used in the setup of a patient prototype. Each key includes a shaft, a cervical platform, a retention knob and preferably at least one channel for the expulsion of excess adhesive fluid. The cervical platforms are shaped to provide intimate contact with a base of their respective tooth. The same tooth/key pairs are then used to make a framework pattern from the setup positioning. The pattern can be cast or scanned for direct machining to produce the finished framework.

A dental implant has a coronal body formed of solid metal that connects at an interface to a bone fixation body. The bone fixation body is made separately from the coronal body and has a porous structure with a cylindrical shape. The bone fixation body connects to the coronal body after the bone fixation body is separately made from the coronal body.

Methods using additive manufacturing processes for making custom abutments for dental implants and copings for screw retained crowns for dental implants are disclosed herein. The methods for making custom abutments include making a main body portion using an additive manufacturing system and adhesively attaching the main body portion to an insert member that extends into a central bore of the main body portion. The methods for making copings for screw retained crowns include making a coping using an additive manufacturing system, fusing a crown over the coping, and adhesively attaching the coping with crown to an insert member that extends into a central bore of the coping. Custom abutments and screw retained crowns made according to these methods are adapted to be attached onto dental implants previously installed in a patient's mouth.

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). The retention element (4, 104, 104, 104) is integrally formed with or integrally attached to the main body (2, 2).
