A surgical cutting tool guide (20, 320, 420, 520) includes a target arm (30) and primary and secondary sight arms (32A, 32B), which are pivotably attached to the target arm (30) so as to be rotatable with respect to one another about primary and secondary target pivot points (34A, 34B), respectively. A sight (40) includes a sight housing (42), which defines a sight passage (44) for aligning a surgical cutting tool (22) with a sight target axis (46), and is attached to the primary and the secondary sight arms (32A, 32B) such that the sight housing (42) and the primary and the secondary sight arms (32A, 32B), respectively, are rotatable with respect to each other about the primary and secondary sight pivot points (34A, 34B), respectively. The surgical cutting tool guide (20, 320, 420, 520) is arranged to automatically and non-electrically maintain the sight target axis (46) oriented to pass within an offset distance of a target point (60) over an entire range of angles over which the sight (40) directs the sight passage (44) toward the target point (60).

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.

The present disclosure relates to single tooth or full arch dental restoration. In cases where patients have insufficient bone stock for conventional root-form dental implants, current solutions often fail to restore function. The present disclosure describes a transalveolar dental implant for single tooth or full arch dental restoration. The transalveolar dental implant is comprised of a post and a bone plate, the bone plate having a contoured portion fabricated to match the topography of a bony surface of the facial skeleton. Through primary fixation of the contoured portion of the bone plate, the transalveolar dental implant improves function and outcomes in affected patients.

An apparatus for guiding a zygomatic implant dental drill installed in a dental handpiece includes a collar configured to seat on a neck portion of the dental handpiece, with an offset post extending from the collar. A first extension extends from the offset post parallel to the neck portion, and a second extension extends from the first extension. The second extension is oriented parallel to the zygomatic implant dental drill, extending from the first extension to be co-terminal and off-set from the zygomatic implant dental drill. By observing the travel of the second extension along a patient's face, a dental surgeon can guide the zygomatic implant dental drill inside the patient toward the patient's zygomatic bone.

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 zygomatic implant for supporting a dental bridge is provided. The zygomatic implant has a stem with a longitudinal axis having a threaded apical portion, an intermediate portion, and a neck portion having a seat for attachment of an abutment. The zygomatic implant has a head with a polygonal cross section that protrudes atop the neck portion, and two internal threads, each having an axis orthogonal to the longitudinal axis of the stem and a mouth located on a lateral wall of the stem. The two internal threads are arranged longitudinally offset along the longitudinal axis of the stem.

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.
