A dental implant includes a generally cylindrical body, an interior bore, and a non-rotational feature. The generally cylindrical body has a main-central axis and is formed from cold-worked, high strength, commercially pure titanium having an ultimate tensile strength of at least about 900 MPa. The generally cylindrical body has a proximal portion and an opposing distal portion for anchoring the dental implant in bone of a patient. The interior bore is formed in the generally cylindrical body and has (i) a bore-central axis and (ii) a threaded portion for receiving a screw that is configured to removable hold an abutment in engagement with the dental implant. The non-rotational feature is configured to engage the abutment in a non-rotational fashion.

The present invention relates to a dental implant set, more precisely to a zygomatic dental implant set for in-bone dental implant surgeries of the zygomatic arch via intraoral access. The zygomatic dental implant set (100) comprises an implant pin (10) configured to be anchored in the zygomatic bone; an intermediate connecting member (20) comprising a curved shape; wherein a first end (21) of the intermediate connecting member (20) is configured to be coupled directly or indirectly to the implant pin (10); a first extender (30), wherein the first extender (30) is coupled to a second end (22) of the intermediate connecting member (20); a prosthetic abutment (40), wherein a first end (41) of the prosthetic abutment (40) comprises an outer thread (42), wherein the outer thread (42) of the prosthetic abutment (40) is coupled to a first inner thread (23) of the intermediate connecting member (20); and wherein a second end (43) of the prosthetic abutment (40) is configured to receive a dental prosthesis.

A zygomatic dental implant includes a generally cylindrical body, an interior threaded bore, and an asymmetrical external feature. The generally cylindrical body has a coronal portion and an apical portion. The generally cylindrical body has a main-central axis. The interior threaded bore is formed in the coronal portion of the generally cylindrical body for receiving a screw configured to removably hold an abutment in engagement with the zygomatic dental implant. The interior threaded bore has a bore-central axis. The asymmetrical external feature is on at least a portion of a first side of the generally cylindrical body such that the asymmetrical external feature is configured to directly engage alveolar bone of the patient. The asymmetrical external feature includes a plurality of circumferentially extending grooves.

A medical implant and a method of implanting a medical implant are disclosed. The medical implant (20) is elongate and for fixation in a patient, and comprises an apical bone anchoring portion (200) for bone apposition, and an unthreaded coronal portion (210), wherein said coronal portion (210) has a length (L.sub.2) exceeding or equaling a length (L.sub.1) of said apical portion (200), and wherein said apical portion (200) has a maximum outer diameter (D.sub.1) that is equal to or larger than a maximum outer diameter (D.sub.2) of said coronal portion. In a method of implanting a medical implant, an apical part is affixed in the zygomatic bone, and a coronal part is positioned outside the maxilla in the mucous membrane.

A bone foundation guide system having a bone foundation guide with a foundation guide body forming an open surgical space connecting a top of the bone foundation guide body with a bottom of the bone foundation guide body, the bottom contoured to removably affix the bone foundation guide body to the bone of a dental implant surgical site, the body further contoured to guide the cutting of bone from a dental implant surgical site and supporting a dental implant surgical guide; the dental implant surgical guide contoured to removably mate to the bone foundation guide body; wherein a combination of the bone foundation guide and the dental implant surgical guide forms a double open-ended placement channel that passes through a plurality of guiding cylinders held in tandem alignment to aid in the placement of a dental implant that is anchored in a site remote from the mouth.

A guide for guided surgery on zygomatic bone implants for dental prostheses includes a half-bushing and a complementary half-bushing which are connected by a pair of bars. The half-bushings and the bars define a common longitudinal median axis between them; the half-bushings have a U-shaped or semicircular cross-section with mutually opposite concavities directed toward the median axis; the half-bushings and the bars form a seat in which it is possible to insert a work member, such as a burr and a subsequent implant, which can move only along the median axis and rotates about an axis of rotation that coincides with the median axis.

A bone foundation guide system having a bone foundation guide with a foundation guide body forming an open surgical space connecting a top of the bone foundation guide body with a bottom of the bone foundation guide body, the bottom contoured to removably affix the bone foundation guide body to the bone of a dental implant surgical site, the body further contoured to guide the cutting of bone from a dental implant surgical site and supporting a dental implant surgical guide; the dental implant surgical guide contoured to removably mate to the bone foundation guide body; wherein a combination of the bone foundation guide and the dental implant surgical guide forms a double open-ended placement channel that passes through a plurality of guiding cylinders held in tandem alignment to aid in the placement of a dental implant that is anchored in a site remote from the mouth.

An implant includes an implant body and a distraction membrane. The distraction membrane is connected to the implant by a connection element. The connection element is arranged movably at least over a portion of a longitudinal axis of the implant body such that the distraction membrane is slidable along at least a portion of the longitudinal axis of the implant body.

A rotary osteotome for deep reach applications. The body of the osteotome has a tapered end that supports helically spiraling flutes. Substantially margin-less (without margin) working edges are interleaved between the flutes to provide compaction action when rotated in a non cutting direction. The body also has an elongated cylindrical stopper section. An irrigation conduit passes through the center of the stopper section and emerges at a plurality of outlet orifices that function as independent nozzles for irrigating fluid. The outlet orifices are generally elliptical in shape and spaced around the body to maintain balance. The irrigation conduit has a main trunk that opens to a flow splitter, which in turn divides the flow of irrigating fluid into substantially equal branches. Each branch is angled at an acute trajectory relative to the longitudinal axis, in the direction of said apical end, between about 10 and 45.
