Dental prosthesis forming block and method for producing a dental prosthesis from the dental prosthesis forming block
The present invention relates to a dental prosthesis forming block (10) for producing a dental prosthesis (50). The forming block having a pin (20) with a self-tapping outer thread, which is arranged on a first surface (11) of the dental prosthesis forming block (10). The invention further relates to a method for producing a dental prosthesis (50). In this method the dental prosthesis block (10) is provided and the dental prosthesis (50) is produced by removing material from the dental prosthesis forming block (10) by a CAD/CAM method, such that the pin (20) forms part of the finished dental prosthesis (50).
Dental implant
A dental implant that facilitate insertion and can be used in all bone types. The implant includes a body having a coronal end, and an apical end opposite the coronal end. A tapered region may be adjacent the apical end. On the apical part one or more taps are provided so the tap is cutting when rotating clockwise and counter-clockwise. The implant can have at least one variable profile helical thread that extends along the tapered region. The implant can have also micro-threads below the main threads, a gradual compressing tapered core, a self drilling apical end and a narrow coronal region.
Dental implant
The present invention provides a dental implant including: a fixture and an abutment including a coupling leg, and the fixture and the abutment are elastically coupled with each other, the dental implant including: a fixture axial hole inner inclined surface in which an inner diameter of an axial hole is gradually and downwardly reduced from a predetermined position of an inner inclined surface of the fixture; a first coupling part formed with a coupling hole at a predetermined position of the fixture; and a first associated coupling part formed with a coupling protrusion complementarily coupled with the first coupling part, wherein when the first associated coupling part is separated from the first coupling part by rotating the abutment, the coupling protrusion upwardly pushes the abutment from the fixture by elastic repulsion with the axial hole inner inclined surface of the fixture, thus the abutment becomes separated from the fixture.
External drive implantation apparatus for bendable collar implants and method
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.
DENTAL IMPLANT
A dental prosthesis implant which has an endosseous implant portion extending along an implant axis and a transgingival portion extending from the implant portion and forming an implant-prosthetic connection platform is provided. The implant-prosthesis connection platform extends perpendicularly with respect to a prosthetic axis, the prosthetic axis being inclined with respect to the implant axis. The transgingival portion forms a side wall with a diameter equal to or smaller than the diameter of the endosseous implant portion and progressively decreasing at least in a distal transgingival portion ending with the implant-prosthesis connection platform.
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 EVALUATION UNIT
A dental implant evaluation unit is disclosed and described. The dental implant evaluation includes a body portion having threads that mimic the general thread pattern of an actual dental implant, without attempting to copy any of the osseointegrative features of the actual implant. A threaded collar is associated with the body portion, and, in certain embodiments, a safety flange is screwed to the threaded collar. The safety flange prevents the dental implant evaluation unit from infiltrating the sinus of a patient when testing the fit of a maxillary implant. The dental implant evaluation unit can be used by a dentist to evaluate the proper size and fit for an actual dental implant by installing the dental implant evaluation unit, and imaging the same, prior to installing the actual dental implant.
Zygomatic implant with partially interrupted threaded portion
An implant includes an elongated and cylindrical body; conical apical region coated by a screw thread and with at least three helical chambers and semi-spherical end; and a cervical region defined by a smooth cervical surface. The elongated and cylindrical body includes at least one longitudinal strip having a substantially smooth surface. The smooth longitudinal strip is located in the zygomatic implant cervical portion. The connection between the screw threads and the smooth longitudinal strip is made by a transition curvature, and the smooth longitudinal strip is aligned with one of the flat sides of the internal area with hexagonal cross section of the implant prosthetic interface.
Multi-unit dental assembly with off-axis feature
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.
HEALING ABUTMENT SYSTEM FOR CONFIGURING CROWN ABUTMENTS AT AN IMPLANT SITE
An anatomical healing abutment is configured to connect to a dental implant. The healing abutment has a body portion which includes at least three reference marks that provide data to orient the connection axis of the abutment with the that of the dental implant so that certain conventional steps, including healing abutment manipulation, multiple scans, and the taking of impressions, can be eliminated, thereby saving time and effort on the part of the practitioner.
