An implant for insertion within a maxillofacial bone of a patient including a tapered body and one or more threads formed along the body. The one or more threads on one or more lead threads include multiple thread forms including both three-dimensional stabilization thread and standard thread (e.g. v-thread, buttress thread, etc.) forms. The one or more threads including the multiple thread forms provides for maximizing the restriction of lateral movement of the implant within a full or partial osteotomy.

Provided are a dental implant with a nano bacteriostatic structure ring at a transgingival part and a machining method thereof. The transgingival part of the dental implant has a three-level micro-nano composite structure, and the three-level micro-nano composite structure endows a surface of the transgingival part of the implant with functions of promoting adhesion and proliferation of a gingival fibroblast and a gingival mesenchymal stem cell and inhibiting adhesion and growth of various oral bacteria. A preparation method thereof comprises: firstly, injecting bioactive, wear-resistant or corrosion-resistant C, N, Ca and P elements into the transgingival part of the dental implant by a plasma injection method; and then, preparing the three-level micro-nano composite structure at a part in which the elements are injected.

A flexible dental prosthesis system including: a longitudinally elongated flexible screw having a first end suitable for being fitted by means of threading in a dental implant and a second open end that can be inwardly deformed having a threaded hole on its inside and a projecting flange on its outside; a transmucosal post with a through hole suitable for inserting the flexible screw; and an upper connection element having a hole at one of its ends suitable for being coupled on the second end of the flexible screw by means of an inner recess in said hole corresponding with the projecting flange on the outside of the second end of the flexible screw.

An implant device includes an implant with a threaded portion and a drilling portion and a positioning hole respectively formed at two ends of the implant. Pores are recessed into a surface portion of the implant. Each pore has a peripheral wall. The peripheral wall and the surface portion meet an end edge. Adjacent end edges and peripheral walls are joined to cause adjacent pores to communicate one after another, thereby forming communicating channels. When the implant is fastened to a target part, cells derived from the target part are quickly attached to the end edges and enter the channels to attain a smooth adhesion and proliferation. The proliferated cells climb between the pores and channels and become linked to hold the implant firmly and enhance the combination between the implant and the target part, thereby shortening the convalescence period of the target part.

An implant fixture is disclosed. The implant fixture contains an elongated shaft section, and a head section, wherein the head section contains at least one concave area for bone growth therein.

The present invention provides a mid-gingival dental implant system that includes a dental implant having a threaded body portion and a superstructure extending from a coronal surface of the threaded body portion. The superstructure includes two O-ring housings for housing deformable O-rings. The mid-gingival system can also include two screws. One for screw retained final components and one for cement retained final components.

The present invention relates to a dental implant having at least one but preferably a plurality of split fins that are vertically spaced along the vertical axis of the body portion of the implant. These split fins hold the body portion of a dental implant stationary within the patient's jaw by engaging the patient's jawbone and promoting osseointegrationthe growth bone around and on the surface of the implant. Each split fin has a first end that is vertically spaced from a second end along the implant body's vertical axis such that the split fin extends from the first end and around the body's circumference along an inclined plane until it terminates at the second end so that the split fin creates a single spiral that extends around the entire circumference of the body portion of the implant.

A magic threader for a dental implant is disclosed, particularly, a dental implant capable of increasing coupling strength under a stable structure by specifying thickness of a thread portion, and pitch between thread portions in consideration of a difference in strength between titanium and bone to decrease stress of an alveolar bone by the thread portion and prevent damage to the alveolar bone and is capable of conducting compression of the thread portion for the alveolar bone in only one direction (direction A), minimizing compression of the thread portion for the alveolar bone in a direction B or a direction C inclined with respect to direction A, and maximizing stress dispersion by configuring the thread portion in a rectangular plate shape and specifying an angle of the screw thread in a specific numerical range.

The invention relates to a method for producing a metal stamp for embossing a nano- or microstructure on a metal device (4), comprising the following steps for producing a 3D structured embossing area (3) on the stamp: a) providing a master (30) having a structured surface (30a), and replicating said master (30a) in the surface of a soft stamp (31); b) forming an imprint (32) on the soft stamp (31a) using a cross-linkable material to form an imprint structured surface (32a), before, while or after contacting an opposite side of the imprint (32) with said surface portion of the metal stamp, and removing said soft-stamp (31) exposing said imprint structured surface (32a); c) etch-opening said surface (32a) using a first set of etching conditions; d) using a second set of etching conditions, different from the first ones, etching the surface of the metal stamp to form said embossing area (3).

A method of forming an implant to be implanted into living bone is disclosed. The method comprises the act of roughening at least a portion of the implant surface to produce a microscale roughened surface. The method further comprises the act of immersing the microscale roughened surface into a solution containing hydrogen peroxide and a basic solution to produce a nanoscale roughened surface consisting of nanopitting superimposed on the microscale roughened surface. The nanoscale roughened surface has a property that promotes osseointegration.
