A method for manufacturing at least one bone anchor and a corresponding drilling template, wherein the bone anchor has an anchor plate which is to be fixed to the surface of a bone by means of one or several screws having a screw head. The anchor plate thus has a bone side which is to connect to the surface of the bone and a free side which is opposite to said bone side. Further, a method for manufacturing a drilling template is described, making it possible to make bore holes in the bone at predetermined positions and to screw the bone anchor to the bone according to predetermined orientations.

A polymerizable composition, which includes (a) at least one radically polymerizable oligomer, (b) at least one radically polymerizable monomer and (c) at least one initiator for the radical polymerization, characterized in that the radically polymerizable oligomer (a) is selected from the group consisting of aliphatic urethane (meth)acrylate oligomers, epoxy (meth)acrylate oligomers and polyether urethane (meth)acrylate oligomers, and the radically polymerizable monomer (b) is polyfunctional.

Methods and systems are described that receive intraoral scan data in response to an optical scan of a surface of the tooth and a material disposed between the tooth and a gingiva surrounding the tooth, the material separating the surrounding gingiva from the tooth and covering a sub-gingival surface of the tooth. The received intraoral scan data is processed to differentiate the first optical scan data associated with the sub-gingival surface of the tooth and the second optical scan data associated with the material covering the sub-gingival surface of the tooth. The three-dimensional model of the tooth is generated based on the first optical scan data that is associated with the sub-gingival surface of the tooth and the third optical scan data associated with the tooth surface that is not covered by the material such that the three-dimensional model of the tooth includes the sub-gingival surface of the tooth.

A dental assembly includes a prosthesis having a base and a plurality of artificial teeth, and at least one connecting element coupled to the prosthesis and configured to facilitate coupling of the dental assembly to a patient's oral cavity. The at least one connecting element includes a cylinder with a body having a first end, a second end, and a passageway extending between the first and second ends. The connecting element further includes an opening through a sidewall of the cylinder that is open to the passageway. The slot allows access to a fixation screw positioned in the cylinder from a direction that is angled relative to an axis of the cylinder. A method of making a dental assembly is also disclosed.

A dental implant has an implant body made of diamond material, the implant body being provided with a bore hole that has at least one lateral dimension and a depth dimension, the lateral dimension and the depth dimension being mm sized. The bore hole is substantially formed by laser light being directed at the implant body to form said bore hole by softening said diamond material at an intended location of said bore hole. The bore hole is further defined by utilizing at least one metallic drilling tool to remove more of the diamond material after initial formation of the bore hole by said laser light. Preferably, the drilling tool has a cone shaped drilling head or a rectangular drilling head.

A shell removal device includes a platform configured to secure a mold. An untrimmed shell is formed over the mold. The shell removal device further includes a drive mechanism configured to move the platform away from the untrimmed shell responsive to sensor data indicative that the untrimmed shell has begun to separate from the mold.

A lower region of a temporary abutment includes an anti-rotational feature for non-rotationally mating with a dental implant. An upper region of the temporary abutment includes a first anti-rotational structure and at least one retention groove. A top surface of the temporary abutment includes one or more informational markers that provide information concerning the dental implant. A temporary abutment cap is configured to be coupled to the upper region of the temporary abutment. The temporary abutment cap has at least one projection configured to mate with the at least one retention groove of the temporary abutment. The temporary abutment cap has a second anti-rotational structure that is configured to slidably engage the first anti-rotational structure of the temporary abutment. The temporary abutment cap is configured to be coupled with a temporary prosthesis such that the temporary prosthesis and the temporary abutment cap are removable from the temporary abutment.

A dental abutment core with a prosthetic connection, a pillar and a shoulder located between the prosthetic connection and the pillar. The pillar has anti-rotational elements for preventing a custom body from rotating with respect to the dental abutment core. The pillar has a first portion adjacent to the shoulder, a second portion adjacent to the first portion, and a third portion farthest from the shoulder. A cross section of at least part of the first portion is circular and has an outer diameter which is lower than a cross section dimension of the second portion. The anti-rotational elements are located in the third portion. A method for manufacturing a dental abutment with such dental abutment core is also described.

Embodiments relate to automating removal of an untrimmed shell from a mold. In one embodiment, a shell removal device includes a body and a platform disposed within the body. The platform is configured to secure a mold that has an untrimmed shell formed over the mold. The shell removal device further includes a cover configured to secure the untrimmed shell to an upper surface of one or more sidewalls of the body and provide a seal between a lower surface of the untrimmed shell and the upper surface of the one or more sidewalls of the body. The shell removal device may include a media inlet in the body to permit pressurized media into the interior of the body to cause a pressure differential between an upper surface of the untrimmed shell and the lower surface of the untrimmed shell to cause the untrimmed shell to release from the mold.

A lower region of a temporary abutment includes an anti-rotational feature for non-rotationally mating with a dental implant. An upper region of the temporary abutment includes a first anti-rotational structure and at least one retention groove. A top surface of the temporary abutment includes one or more informational markers that provide information concerning the dental implant. A temporary abutment cap is configured to be coupled to the upper region of the temporary abutment. The temporary abutment cap has at least one projection configured to mate with the at least one retention groove of the temporary abutment. The temporary abutment cap has a second anti-rotational structure that is configured to slidably engage the first anti-rotational structure of the temporary abutment. The temporary abutment cap is configured to be coupled with a temporary prosthesis such that the temporary prosthesis and the temporary abutment cap are removable from the temporary abutment.
