The present disclosure relates to a coating method of implant using parylene, for coating a surface of a dental implant, including a pretreating step of pretreating the implant; and a coating step of coating a surface of the pretreated implant with a coating material to form a polymer coating layer, wherein the coating material is provided as parylene.

According to the present disclosure, a parylene thin film may be uniformly coated on the surface of the dental implant, and according to such a thin film, the growth of anaerobic bacteria can be effectively inhibited in spaces where the fixture and the upper structure of the dental implant are joined to each other, and where the upper structure and the crown are joined to each other.

Described herein are systems and methods for extracting a broken fragment of a dental abutment screw from a dental implant. One such system includes an extractor tool having a tubular outer body and a conductor positioned within the tubular outer body, and an applicator that receives and end of the extractor tool and also includes a heating element that converts electrical energy into heat that is conducted to the extractor tool to melt a thermoplastic adhesive in a cavity at the distal end of the extractor tool, such that the melted thermoplastic adhesive can conform to and engage with a broken fragment of a dental abutment screw within a dental implant when the adhesive cools. The extractor tool can then be rotated to unscrew the broken fragment from the dental implant.

Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.

There is provided an implant having a slack prevention function by an eccentric fitting structure. An engaging shaft 53, which is decentered with a screw shaft 52, is provided at the end of an abutment screw 5, and is engaged with an engaging hole 45 provided in the bottom of a screw hole 44, into which an abutment screw 5 is screwed, and thus, the screw shaft 52 is inclined to and eccentric from the screw hole 44. Thereby, the screw shaft 52 comes to be strongly pressed partially in a circumferential direction toward the screw hole 44, so that internal stress in the horizontal direction is accumulated on the screw shaft 52. The screw 5 is threaded with maintaining prevailing torque caused by the internal stress, which enables the screw 5 to be fastened to the right position.

The present invention relates to a dental implant, and more particularly, to a dental implant including a fixture 10, an abutment 30 coupled to an upper end of the fixture 10, and an abutment fixing screw 40 coupling the abutment 30 to the fixture 10. The fixture 10 is molded of ceramic and includes a screw part 13 disposed on an outer circumferential surface and a screw hole 14, to which the abutment fixing screw 40 is coupled, disposed in a central axis direction. A helical coil 20 is disposed between the screw hole 14 of the fixture 10 and the abutment fixing screw 40 to couple an outer portion 21a of the helical coil 20 to a screw valley 14a of the screw hole 14 of the ceramic fixture 10 and an inner portion 21b to a valley 41a of the screw part 41 of the abutment fixing screw 40 in a screw coupling manner.

A dental component comprising a fixture engagement portion for engaging the dental component with a dental fixture adapted to be inserted into a jawbone or for engaging the dental component with a fixture replica.

The invention relates to a superstructure support (20) as part of a prosthetic tooth replacement (1) between an implant body (10) and a superstructure, comprising a hollow implant post (23, 150, 160, 170, 180, 190), a hollow implant pin (50), and an implant flange (31) lying therebetween. The cavity zones (67, 62) of the implant post (23, 150, 160, 170, 180, 190) and of the implant pin (50) transition into each other. The center lines (69, 63) include an angle of 60 to 86 angular degrees. An attachment element (5) can be arranged on the implant post (23, 150, 160, 170, 180, 190) in a rotationally fixed manner by means of an assembly joint (140), which forms an interface (141, 145). The attachment element (5) is a cap-type element. At least some areas of the implant flange (31) have a supporting enveloping surface (37). The attachment element (5) has an interface geometry (146), which can be mounted on the interface geometry (142) of the superstructure support (20) in an interlocking and/or frictional manner at least in some areas. By means of the invention, a superstructure support (20) for the prosthetic tooth replacement is improved in such a way that the interface between the implant post (23, 150, 160, 170, 180, 190) and the attachment element (5) enables secure and simple joining and disconnecting of the interface components.

Prosthetic dental device comprising a first axial-symmetric intraosseus component, or implant (11) and a second component, or abutment (12) configured to be connected on one side to the first intraosseus component (11) and to support, on another side, a prosthetic dental component.

A dental implant screw for engaging a tightening apparatus and a dental implant. The dental implant screw extends through a dental tibase and a dental prosthetic. The dental implant screw includes a shaft portion and a head portion, with the shaft portion comprising a shaft having threads disposed at least partially along the length of the shaft and the threads configured to engage the dental implant. The head portion includes a top, a sidewall, and a bottom terminating in the shaft portion. The top includes a bore for receiving the tightening apparatus. The sidewall is conical, having its largest circumference proximal the top, and its smallest circumference proximal the bottom. The sidewall makes complete contact with the tibase when fully inserted into the dental implant.

Dental implants including radiopaque markers provided therein or thereon. The implant may also include customizable length characteristics. For example, a kit may include implants with different diameters (e.g., 3 diameters), where all of the implants are of a single (e.g., long) length. The appropriate diameter implant may be selected from the kit by the practitioner, and the long length implant may be cut (e.g., with a dental drill) to the appropriate length needed. The implants include radiopaque markers on or within the implant. For example, three series of markers may be provided on different “faces” of the implant, so that the three series of markers serve as reference points when scanning, allowing triangulation of the exact position of the implant in relation to the surrounding hard and soft oral tissues.
