Dental assemblies for a mouth of a patient are provided. Contemplated dental assemblies can comprise an implant having an upper portion and a lower portion, wherein the upper portion comprises a threaded portion configured to screw into a threaded recess of an abutment, and wherein the lower portion comprises an angled platform and a threaded post extending from the platform, the threaded post configured for threaded engagement with bone or tissue in the mouth of the patient. In some aspects, the angled platform can be angled, for example, about 15 degrees, about 20 degrees, about 30 degrees, between 10-35 degrees, or between 15-30 degrees relative to a line that is orthogonal to a length of the implant.

A dental assembly is provided, which includes an endosseous dental implant, a retention member, and a cap configured for securing in a dental appliance and engaging the retention member. The endosseous dental implant may have an external projection extending from the top of the first end portion for releasable engagement with an abutment member, wherein the abutment member has an external lower bevel portion. The retention member may have a first end and a continuous, unbroken skirt extending from the first end defining an inner surface for engagement over the outer locating surface of the abutment member, the retention member being constructed from a rigid material such that it provides a retentive force of about 10 to 75 pounds. The rigid material may include PEEK.

A dental implant includes a screw body and screw threads. The screw body has an apical end and a coronal end. Screw threads include a primary thread and a secondary thread, which overlap in at least a portion of the screw thread. Thread depth progressively increases from the coronal end to the apical end. The coronal end may contain any suitable secondary characteristics, such as machined threads, grooves, micro-threads, or any other characteristics favorable to successful outcomes with dental implant treatment. A method of making such a dental implant is also disclosed.

Highly self-tapping dental implant system with hybrid cone type connection and interlocking rails, which allows high insertion (or removal) torque and double parallel cone locking between the implant, prosthetic abutment and internal screw, even in its 3.0 mm diameter embodiment, and gives the whole system high primary and secondary stability, optimal watertightness thanks to the double cone sealing, as well as predictable long-term fixation of the dental prosthesis on the 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.

An intraosseous dental implant for the application of biologically active agents directly to the surrounding soft tissues and bone tissue, and their substitutes, is described. The implant enables the measurement of the newly formed or lost bone tissue volume immediately adjacent to the implant. Increasing the dynamics of osseointegration growth directly results in the possibility of reducing the duration of the entire treatment protocol. To increase dynamics of the osseointegration process, the type of material from which the implant is made, its design features, surface topography, as well as the formation of layered structures and coating applications, are described. The implant introduces growth factors and other biologically active factors that affect an increase in the dynamics of osseointegration strength. The entire implant or a porous section thereof can be produced by 3D printing through selective melting/sintering of biocompatible metallic, ceramic, or metallic-ceramic composite powders with laser or electron beams.

This invention discloses a dental implant able to enhance stability for solving the problem of insufficient support of prior arts. The dental implant of this invention includes: a first threaded section having a first diameter which decreases toward a free end of the first threaded section along a longitudinal axis; a second threaded section connected with the first threaded section and having a second diameter larger than the first diameter; a cut-in section obliquely extending from one end, away from the first threaded section, of the second threaded section outwards and having a tip with a feature of sharpness for cutting into an alveolar bone of a patent in a dental implant surgery; and a head section connected with the cut-in section for receiving a force to facilitate the dental implant to move into the alveolar bone. The dental implant of this invention can enhance preliminary and long-term stability.

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.

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.

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.
