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.
ANCHORAGE DEVICE FOR DENTAL PROSTHESES
A device for anchoring to the upper jaw bone dental prostheses of the upper dental arch using a plurality of intraosseous screws each provided with a thread and a bottom shank. A crosspiece with a plurality of nuts corresponding to the number of intraosseous screws are connected together by means of spacers, each nut having a female thread corresponding to the thread of a respective intraosseous screw. A lock nuts corresponding to the number of intraosseous screws are each provided with a female thread in turn corresponding to the thread of the respective screw. The crosspiece is designed to be inserted and housed, during use, in the maxillary sinus and the each screw is inserted inside a respective hole through the bone underneath the maxillary sinus so that it projects beyond the inner cortex of the bone and is inserted inside the respective nut of the crosspiece.
OSSEOINTEGRABLE IMPLANTS AND SCREWS COMPRISING STRUCTURALLY POROUS SURFACE, PROCESS FOR PREPARING THE IMPLANTS AND SCREWS AND USES THEREOF
The present invention relates to implantable medical devices (dental and orthopedic) (osseointegrable implants) textured by the additive manufacturing process. Such implants are prepared in such a way as to comprise a larger surface area of contact between implant/adjacent tissues, porous microstructure with complex geometry with controlled and diversified pore size, which confers several technical advantages. In addition, the present invention relates to the process of preparing said implants and/or screws with an optimized structure for accelerating osseointegration. Finally, the present invention refers to the use of said implants as carriers of drugs or cells in order to treat the site, promote its healing, tissue regeneration or promote cell growth.
DENTAL SUPPORT SCREW
An implantable screw for maintaining horizontal and/or vertical space during bone grafting procedures. The screw includes a head having a top surface configured to engage a dental membrane, a shaft, and a tip. The shaft is at least partially threaded to engage bone. The dental membrane and the screw provide space for bone growth material during bone grafting.
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 having reverse-tapered main body for anterior post-extraction sockets
A dental implant includes a body and a threaded surface. The body has an upper portion, a middle portion, and a lower portion. The upper portion of the body includes a generally cylindrical region. The lower portion of the body includes a generally inwardly tapered region. The middle portion of the body includes an outwardly extending bulge. A maximum outer diameter of the bulge is greater than (i) a maximum outer diameter of the upper portion and (ii) a maximum outer diameter of the lower portion. The threaded surface is on the body within at least the upper portion of the body, the bulge, and the lower portion of the body.
Omnidirectional multi-unit abutment system for screw-attached dental prostheses
A multi-unit abutment aligning a dental implant and a screw-attached prosthesis with copings is disclosed. The multi-unit abutment has a threaded base post for attachment to the implant and a ball portion. A swivel shell surrounds the ball and may be fixed in position with a lock screw. A drive feature on the ball allows a tool passing through the lock screw to drive the base post into the implant with the multi-unit assembly in a linear configuration. The swivel shell is then positioned and fixed at a desired tilt and azimuthal angle. The swivel shell has a mating surface for a coping. The lock screw remains accessible through an aperture in the coping when the prosthesis is positioned on the implant abutments. Different embodiments are disclosed for capturing the swivel shell on the ball. Methods for improving passive alignment of the prosthesis to the implants are described.
Dental Implant, Superstructure, And Dental Prothesis
Dental implant and superstructure each with an interface that allows direct attachment of the superstructure to the dental implant without the use of an abutment. The dental implant comprises an anti-rotation element that is arranged in the opening and is configured to prevent the superstructure from rotating about a longitudinal axis relative to the dental implant. The superstructure comprises an interface corresponding to the anti-rotation element, having a recess with two mutually opposite side flanks which are at a first distance from each other in a first region and, in a second region which is at a greater distance from the longitudinal axis than the first region, are at a second distance from each other, the second distance being smaller than the first distance.
DENTAL IMPLANT WITH IMPROVED STABILIZATION THREAD FORM AND CUTTING ELEMENTS
An implant for insertion within a maxillofacial bone of a patient, for example a dental implant, including a three-dimensional stabilization thread form extending along at least a portion of the implant body in a first helical direction, and one or more grooves or channels extending through the three-dimensional stabilization thread form in a generally opposite second helical direction, whereby one or more cutting edges are formed at the intersection of the one or more grooves or channels with the three-dimensional stabilization thread form.
Implant and abutment tooth assembly
An implant and abutment tooth assembly includes an implant, a rotatable connector, a screw bolt, and a photocurable resin capsule. The implant includes a threaded section and a rotatable adjustment seat, wherein the rotatable adjustment seat has an upper connection portion. The upper connection portion has a groove, two spherical portions, and a receiving trench. The rotatable connector includes a spherical rotation face, two end faces, an abutment, an internal screwing section, and a stepped notch. The screw bolt includes an external screwing section, a rotary head, and a force segment. The external screwing section is screwed with the internal screwing section of the rotatable connector, and the rotary head is movably received in the stepped notch of the rotatable connector. The photocurable resin capsule includes 0.1 g to 0.8 g of light-cured resin and is accommodated in the receiving trench of the implant.
