Asymmetric zygomatic dental implant with partial micro thread/groove

A zygomatic dental implant comprising:

• a generally cylindrical body having a coronal portion and an apical portion, the apical portion for anchoring the zygomatic dental implant in zygoma bone of a patient, the generally cylindrical body having a main-central axis, and the coronal portion including a generally flat feature, a length of the generally flat feature, along the main-central axis, is between about 50 percent and about 75 percent of a length of the zygomatic dental implant;
• an interior threaded bore 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 having a bore-central axis that is nonparallel to the main-central axis;
• and
• a plurality of circumferentially extending grooves on the coronal portion of the generally cylindrical body configured to directly engage alveolar bone of the patient.

A zygomatic dental implant comprising:

• a generally cylindrical body having a coronal portion, an apical portion, and a middle portion between the apical portion and coronal portion, the generally cylindrical body having a main-central axis, the apical portion including threads for anchoring the zygomatic dental implant in zygoma bone of a patient, the coronal portion including a threaded region for assisting in anchoring the zygomatic dental implant in alveoloar bone;
• an interior threaded bore 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 having a bore-central axis that is nonparallel to the main-central axis;
• and
• an asymmetrical external feature within the coronal portion configured to directly engage alveolar bone of the patient, the asymmetrical external feature including a plurality of circumferentially extending grooves, the plurality of circumferentially extending grooves being located coronally above the threaded region of the coronal portion.

A zygomatic dental implant comprising:

• a generally cylindrical body having a coronal portion, an apical portion, and a middle portion between the apical portion and coronal portion, the generally cylindrical body having a main-central axis, the apical portion including threads for anchoring the zygomatic dental implant in zygoma bone of a patient, the coronal portion including a flat platform surface;
• an interior threaded bore formed in the coronal portion in the region of the flat platform surface for receiving a screw configured to removably hold an abutment in engagement with the zygomatic dental implant, the interior threaded bore having a bore-central axis that is nonparallel to the main-central axis, the bore-central axis being perpendicular to the flat platform surface;
• and
• a flat surface formed in the coronal portion and located below the flat platform surface, the flat surface having a width that varies along a length of the flat surface as measured along the main-central axis.

• and
• a plurality of circumferentially extending grooves on the coronal portion of the generally cylindrical body configured to directly engage alveolar bone of the patient;
• the plurality of circumferentially extending grooves includes a first portion of circumferentially extending grooves and a second portion of circumferentially extending grooves, wherein ends of the first portion of circumferentially extending grooves taper inwardly in an apical direction, and wherein ends of the second portion of the plurality of circumferentially extending grooves taper outwardly in the apical direction.
