11490997 · 2022-11-08 · ·

The invention relates to an adapter (1, 1′) for attaching a dental superstructure (50) to a dental implant (30). The adapter (1, 1′) comprises a coronal attachment portion (2, 2′) for attaching the adapter (1, 1′) to the dental superstructure (50), an apical attachment portion (4) for attaching the adapter (1, 1′) to the dental implant (30) and an intermediate portion (6) arranged between the coronal attachment portion (2, 2′) and the apical attachment portion (4). The apical attachment portion (4) is a protrusion defining an apical end portion of the adapter (1, 1′) and configured to be received in a corresponding recess (32) of the dental implant (30). The protrusion is rotationally symmetric, so that the adapter (1, 1′) is rotatable relative to the dental implant (30) in the state of attachment of the adapter (1, 1′) to the dental implant (30). Further, the invention relates to a dental assembly comprising the dental superstructure (50) and at least one such adapter (1, 1′).

Laser-assisted periodontics

Periodontal disorders such as disorders associated with a dental implant are treated with a laser where an average laser power along with other laser parameters provide particular settings for the treatment, the treatment including one or more of creating a gingival trough or flap around the implant, ablating or denaturing infected tissue via photothermolysis, lasing a pocket around the affected implant, and compressing marginal tissues against the implant.

In some aspects, dental drill guides can include a body defining an outer surface and an interior hole for receiving and positioning a dental drill; a first end of the body defining a tapered lead-in portion of the outer surface; a second end of the body opposite the first end defining at least one lip feature configured to be gripped by a handling tool; an outer circumferentially formed recess around the outer surface; and a seating feature extending from the outer surface.

Screw retained abutment with off-axis feature and methods of making and using same

An abutment is provided with a screw access hole and a slot in its sidewall adapted to allow a driver to access a screw in the screw access hole at an angle relative to a longitudinal axis of the screw. The abutment may include a screw seat and may be connected to an implant via a screw in the screw seat. A prosthesis, which may include a driver access channel that has a diameter less than the outer diameter of the drive portion of the screw, may be placed over the abutment. Methods of making a dental prosthesis and methods of attaching and removing the dental prosthesis from the implant are also disclosed.

Dental implant guiding tool set and dental implant guiding sleeve thereof
11612453 · 2023-03-28 · ·

A dental implant guiding tool set and a dental implant guiding sleeve thereof are disclosed. The dental implant guiding tool set includes a handpiece, a dental implant guiding sleeve and a tooth mold fastening device. The dental implant guiding sleeve includes a handpiece head guiding hole disposed axially and corresponding to a shape of the handpiece head of the handpiece, a lateral opening disposed on a side of the handpiece head guiding hole and corresponding to a connection handle of the handpiece. The dental implant guiding sleeve can directly guide the handpiece head of the handpiece, to prevent the dental implant guiding sleeve from directly contacting the drill bit mounted on the handpiece. Therefore, a conventional drill bit can be directly used for a guiding dental implant operation, and the minimal required operation space of the dental implant guiding tool set can be reduced.

Forceps for removing dental implant fixture
11484393 · 2022-11-01 ·

An object of the present invention is to provide forceps for removing a dental implant fixture, in which pinching portions securely hold a fixture to remove the fixture implanted in an alveolar bone, and thus to prevent the pinching portions from slipping out of the fixture. Forceps for removing a dental implant fixture according to the exemplary embodiment of the present invention include: a pair of handles; coupling portions extended from the handles, crossed, and hingedly coupled; pinching portions connected to the coupling portions; and holding pieces protruding from ends of the pinching portions in a direction toward a center of a dental implant fixture and each having an arc corresponding to at least a part of an outer circumference of the fixture so that the holding pieces are inserted into a trough of a threaded portion formed on the outer circumference of the fixture.

DENTAL DRILL

The present invention relates to a dental drill (10) formed of titanium or a titanium alloy having a hardness greater than pure titanium, said drill extending along a central axis (A) from a proximal end (14) to a distal end (16). The drill comprises a shank (12) arranged in a proximal end region of the drill (10) and extending along the central axis (A), a flute portion (20) arranged distally to and running coaxially with the shank (12), said flute portion (20) comprising two or more flutes (22a, 22b, 22c) extending along the flute portion (20) and being interposed by lands (24a, 24b, 24c), the flute portion further comprising a central solid web and a drill tip (26) directly adjoining the distal end (28) of the flute portion (20) and comprising two or more flanks (25a, 25b, 25c) which taper radially inwardly from the distal end of each land in the distal direction toward the central axis (A), each flank (25a, 25b, 25c) comprising a cutting edge (30a, 30b, 30c). According to the invention, at the distal end of the drill point (26) at least one groove (32, 33a, 33c) is formed in the web such that the distal most end (36a, 36b, 37b, 37c) of at least one of the flanks (25a, 25b, 25c) is located radially remote from the central axis (A).

EXTERNAL DRIVE IMPLANTATION APPARATUS FOR BENDABLE COLLAR IMPLANTS AND METHOD
20230086280 · 2023-03-23 · ·

An external drive apparatus for bendable collar implants includes a male fastener and a female driver. The male fastener is constructed as a rigid and integral unity including an implant screw, a collar, and a male screw-top drive. The female driver supports a female screw-top drive. The female driver is configured for application of an implantation torque to the implant screw via the male screw-top drive which is disposed distally away from the collar.

IMPLANTATION KIT ENABLING IMPLANT HOLE PREPARATION ON BONE IN ONLY ONE DRILLING WITH ONE SINGLE OSTEOTOME
20230085400 · 2023-03-16 ·

An implantation kit including a rotational osteotome and an implant is disclosed. The rotational osteotome includes a plurality of steps of different diametrical sizes, a tip, and at least one flute; and every step includes an annular bottom bevel to provide a cutting edge and recessed section. The implant includes a body having a cylindrical head section and a conical section provided with an external thread and a plurality of spiral flutes. The conical section has a downward tapered profile correspondingly aligned with the recessed sections. The cylindrical head section has a straight cylindrical profile matching that of the step having the largest diametrical size. With the above arrangements, an implant hole on a bone can be formed in only one drilling with one single osteotome for fixedly holding the implant therein. Therefore, the time needed for dental and orthopedic surgeries is largely shortened while better osseointegration can be achieved.
