Disclosed is a dental prosthetic device having an implant, a cap and an abutment interposed between the implant and the cap. The abutment includes an abutment head which is at least partially delimited by an abutment external face and which is configured to retain the cap. The abutment has an abutment body with an attachment to the implant. Retention is accomplished by a nesting arraignment for fitting the abutment head inside a cavity which is formed inside the cap and which is at least partially delimited by a cap internal face. The cap is screwed onto the abutment head. The cap internal face is provided with a tab which is in contact against the abutment external face. A space is left between a point of contact of the cap internal face and a cone lip of the cap internal face between the abutment external face and the cap internal face.

A system for dental implant restoration is provided. It includes universal aligning adaptors and prosthetic components having co-operable indices, which together form a translational, integrating system which aligns, synchronizes, and references the prosthetic components about an implant's central axis of rotation. Rotation of an adaptor about a prosthetic component, with its reference point becoming aligned to a predetermined reference point on the prosthetic component, followed by the rotation of the adaptor/prosthetic component assembly about the implant, situates the prosthetic component in a predetermined position such that all other prosthetic components become synchronized to the adaptor's reference point. The prosthetic component is mechanical for clinical or lab bench use, or is virtual for restoration design in a software program, prior to milling prosthetic abutments or devices. Abutments, healing caps and screw access holes are realigned to preferred positions and synchronized with minimal deviation from the ideal direction.

A dental screw for osseointegration of a bone surface includes a base, a healing cap, and a handle. The base includes a penetrating body configured to penetrate into a bone. An area of the penetrating body at a proximal side of the base is smaller than an area of the penetrating body at a distal side of the base.

A temporary alignment system, methods, and accessories for holding a dental coping to an implant abutment using a separable fastener using the same threads in the implant abutment used for definitive attachment are disclosed. The disclosed temporary fasteners initially orient and hold a coping against an implant abutment with a force along the same axis as the semi-definitive screw. The aligned coping can be picked-up in a closed-tray impression process without unscrewing the temporary fastener. Embodiments include threaded posts that release copings from the implant abutment through axial forces. Some embodiments include a threaded post with separable cap that is picked-up with the coping. Methods and accessories for using the separable fastener assembly or portions of it during conversion of an existing prosthesis for screw attachment or fabrication and fitting of a new prosthesis are described.

A pontic device for preserving soft tissue in a tooth-extraction site includes a generally curved apical end. The apical end has a first perimeter and is configured to rest in a tooth extraction socket and substantially conform to soft tissue of a tooth-extraction site immediately after a tooth has been extracted. The pontic device further includes an opposing, generally concave coronal end. The coronal end has a second perimeter that is configured to substantially correspond to and form a seal with gingival tissue surrounding the tooth-extraction site. The coronal end is configured to receive a tooth-shaped coronal pontic portion to form a final restoration.

A semi-synthetic hybrid material having a pH from 7 to 7.4 includes an inorganic fraction and a cross-linked organic fraction. The method for producing this material, and osteosynthesis devices or implants made of semi-synthetic hybrid material are also described.

The present application relates to an abutment system (12) and its use. The abutment system (12) comprises: a soft tissue level abutment part (10) adapted to be attached to a bone level dental implant (40) by means of an abutment screw (56), wherein the abutment system is adapted to selectively support both a cement-retained final restoration (66) and a screw-retained prosthetic component (68; 70). The present application also relates to dental methods.

A removable system and method for helping position and stabilize implant supported dentures during the healing process after surgery is provided, wherein a removable system comprises a soft tissue supported provisional denture structure configured to help position and stabilize the provisional denture during the transfer of the implant positions to the provisional denture. In the surgical process of providing implant-supported dentures, immediately after the implants are surgically implanted, adhesive is applied to the underside of the provisional denture, and implant connectors are seated on the implants. The provisional denture is seated in the patient's mouth wherein the soft tissue supported provisional denture structure helps stabilize and position the denture. The implant connectors adhere to the adhesive and transfer the implant positions to the provisional denture.

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 implant system includes an anchoring part of a ceramic material for anchoring in bone tissue, an abutment of ceramic material, and an abutment screw. The anchoring part has a recess that is open towards a coronal end for engagement of a fastening post of the abutment. The abutment has an opening that is continuous in the axial direction and into which the abutment screw can be inserted. The abutment screw is configured, for a fastening of the abutment to the anchoring part, to engage into an inner thread that is formed on the anchoring part in the recess or is present on an insert element that is inserted into the recess. The abutment screw has a screw head, and a shoulder, which is formed coronally and which together with the screw head forms a stop on inserting the screw into the opening, is present in the opening.
