Although the term lingual is technically specific to the mandible, this term is applied herein to the maxilla (not shown) as well. Moreover the term lingual is also applied herein to describe the surface of mandible 10 adjacent to the tongue (not shown). [018] FIG 2A to 2E show an embodiment of implant anchor 20. Implant anchor

20 comprises a cylindrical shell structure 21 , furnished with screw threading 22 on the exterior surface thereof. Screw threading 22 is adapted to be screwed into osseous tissue of maxilla (not shown) or mandible 10. It is noted that in some embodiments the exterior surface cylindrical shell structure 21 is essentially plane and not furnished with screw threading 22.

[019] Cylindrical shell structure 21 of implant anchor 20 comprises longitudinal polygonal aperture 24, longitudinally extending throughout structure 21 , forming female connectors on both ends of implant anchor 20. Optionally there is a polygonal recess, extending to a partial length adapted structure 21 , forming a female connector on one or both ends of implant anchor 20.

[020] The female connector or connectors formed by longitudinal polygonal aperture 24 or by a polygonal recess are adapted to be operationally connected to a driving tool (not shown). The driving tool is configured to apply, optionally manually, a rotational torque to implant anchor 20 and for manipulating of implant anchor 20.

[021 ] Cylindrical shell structure 21 of implant anchor 20 further comprises vertical cylindrical aperture 26, vertically extending throughout structure 21. Optionally there is a vertical cylindrical recess, extending to a partial height of structure 21. Vertical cylindrical aperture 26 furnished with screw threading 28 on the interior surface thereof. Screw threading 28 is adapted for engagement with respectively matching screw threading.

[022] FIG 3A shows an embodiment of anchored dental implant 30, mounted on mandible 10. Anchored dental implant 30 comprises implant anchor 20 implanted into mandible 10 and crown assembly 40. Crown assembly 40 comprises implant bolt 32 and dental crown 34, mounted on top of implant bolt 32. [023] Implant anchor 20 is screwed into a horizontal bore in mandible 10, drilled in a bucco-lingual direction, as elaborated in a greater detail infra. Implant anchor 20 is screwed into the bore in mandible 10 by a means of driving tool (not shown). The aforementioned driving tool functions essentially as screw driver. The aforementioned driving tool comprises an indicium or structural element indicating the orientation of vertical cylindrical aperture 26, in cylindrical shell structure 21 of implant anchor 20. Consequently upon rotating implant anchor 20 until aforesaid indicium or structural element is in a vertical orientation, cylindrical aperture 26 in cylindrical shell structure 21 is respectively positioned in a vertical orientation.

[024] Dental crown 34 is mounted on top of implant bolt 32, typically a means of adhesives. The terminal portion of implant bolt 32 optionally includes at least one structural element adapted for positioning of dental crown 34 is and/or interaction with an adhesive between the former and the latter.

[025] The exterior surface of implant bolt 32 is furnished with a screw threading, respectively matching the screw threading in vertical aperture 26 in implant anchor 20. Implant bolt 32 is inserted into vertical aperture 26 in implant anchor 20, via a vertical bore in mandible 10, drilled in an inferior direction, namely a corono-apical direction, preferably employing a drill guide assembly, as detailed hereunder. [026] The top portion of implant bolt 32 optionally comprises a circumferential extension or rim, adapted to engage vis-a-vis the superior face of mandible 10 and/or the face of the superior portion of the aforementioned vertical bore, in a corono-apical direction mandible 10. Implant bolt 32 is tightened in mandible 10 by being screwed into respectively matching screw threading 28 in vertical aperture 26 in implant anchor 20. Since implant bolt 32 is affixed in mandible 10 by a means of interaction with implant anchor 20, which is typically substantially harder than the osseous tissue mandible 10, it is expected that implantation of implant anchor 20 as well as affixing of implant bolt 32 mounting of dental crown 34 can be performed in a single procedure; contradistinctively to the implantation techniques known in the art, wherein the anchor is implanted first, whereas the mounting of the crown is only performed following a month or so afterwards.

[027] FIG 3B shows an embodiment of drill guide assembly 50, mounted on mandible 10. Drill guide assembly 50 comprises implant anchor 20 implanted into mandible 10 and drill guide subassembly 60. Drill guide subassembly 60 comprises structured arm 54, drill engagement element 56 and connector 58. Structured arm 54 preferably embodies an essentially C-shaped form.

[028] Implant anchor 20 is screwed into a horizontal bore in mandible 10, drilled in a bucco-lingual direction, as elaborated in a greater detail infra. Connector 58, which is typically a male connector, is connected to the female connector of implant anchor 20, which is typically a female connector, formed by longitudinal polygonal aperture or recess 24, longitudinally extending in structure 21. Structured arm 54 is configured in such a way that upon connecting connector 58 of drill guide subassembly 60 to the female implant of anchor 20, thus forming drill guide assembly 50, drill engagement element 56 is positioned on top of mandible 10, respectively aligned vis-a-vis vertical aperture 26 of implant anchor 20 in mandible 10. [029] Drill engagement element 56 of drill guide subassembly 60 comprises driller guide aperture 62. Driller guide aperture 62 defines drill path 64, the projection of which extends through mandible 10 to vertical aperture 26 in structure 21 of implant anchor 20. A driller (not shown) is then appended through driller guide aperture 62 in drill engagement element 56, so that the driller is complied to follow drill path 64. Consequently the drilling performed by the aforesaid driller (not shown), while appended through driller guide aperture 62, results with a vertical aperture drilled in mandible 10 that is essentially collinear to vertical aperture 26 in structure 21 of implant anchor 20. Performing the drilling through driller guide aperture 62 ensures that the resulting vertical aperture in mandible 10 is essentially collinear to vertical aperture 26 in implant anchor 20 thereby essentially eliminating the risk of drilling the vertical aperture in mandible 10 in a wrong location and/or in wrong orientation and/or in misaligned to vertical aperture 26 in implant anchor 20 as well as minimizes the risk of iatrogenic trauma.

[030] FIG 4A shows an embodiment of assembly 70, comprising implant anchor 20, modular implant anchor insertion cap 72 and connector 76. Implant anchor 20 comprises longitudinal polygonal aperture 24, forming female connectors on both ends of implant anchor 20. Implant anchor 20 further comprises vertical cylindrical aperture 26, furnished with screw threading 28 on the interior surface thereof. Screw threading 28 is adapted for engagement with a respectively matching implant bolt (not shown). [031 ] Modular implant anchor insertion cap 72 embodies a conical or pointed shape and is optionally furnished with screw threading, adapted for penetrating into the osseous tissue of maxilla or mandible (not shown). Modular implant anchor insertion cap 72 comprises polygonal recess 74, forming a female connector, on the posterior face of implant anchor insertion cap 72. Connector 76 is preferably a coaxial double-sided male connector, adapted to engage the female connector of implant anchor 20 as well as the female connector of implant anchor insertion cap 72.

[032] Implant anchor 20 of assembly 70 is inserted into the mandible (not shown) in a bucco-lingual direction. Typically the soft gingival tissue is first removed, from both sides of the mandible (not shown), providing for a complete bucco-lingual exposure of the mandible. An aperture is typically then drilled in the mandible, from the buccal face thereof. Implant anchor 20 is preferably furnished with modular implant anchor insertion cap 72 by connecting the latter to the former by means of connector 76.

[033] Entire 70 assembly is then screwed into the aforesaid aperture from the buccal face of the mandible (not shown), with implant anchor insertion cap 72 facing forwards. Upon emerging on the lingual side of the mandible (not shown), implant anchor insertion cap 72 is removed from implant anchor 20 together with connector 76. A drill guide assembly is then typically connected to implant anchor 20, as specified hereinabove. The drill guide assembly is connectable from the buccal side of the mandible (not shown), typically for the anterior teeth, or from the lingual side of the mandible (not shown), typically for the posterior teeth.

[034] FIG 4B shows an embodiment of assembly 80, comprising implant anchor

20, modular implant anchor insertion cap 72 and spacer connector 82. Assembly 80 is essentially similar to assembly 70, shown in FIG 4A, except of that spacer connector 82 additionally to a coaxial double-sided male connector 76 comprises spacer 84.

[035] Spacer 84 is disposed in between the anterior face of implant anchor 20 and posterior face of implant anchor insertion cap 72. Consequently the anterior face of implant anchor 20 is optionally does not emerge from the lingual side of the mandible (not shown) but rather stays buried inside the mandible. In such a case spacer 84 of spacer connector 82 ensures that implant anchor insertion cap 72 has emerged from the lingual side of the mandible (not shown) and is readily disconnectable from implant anchor 20, while implant anchor 20 is inside the mandible.

[036] FIG 4C shows an embodiment of implant anchor 90. Implant anchor 90 comprises a cylindrical structure 91 , embodying integral insertion cap 92, on the anterior face thereof. Cylindrical structure 91 of implant anchor 90 comprises longitudinal polygonal recess 24, extending to a partial length adapted structure 91 , forming a female connector on posterior face of implant anchor 90. Implant anchor 90 further comprises vertical cylindrical aperture 26, furnished with screw threading 28 on the interior surface thereof, adapted for engagement with a respectively matching implant bolt (not shown). [037] Implant anchor 90 is essentially similar to assembly 70, shown in FIG 4A, except of that insertion cap 92 forms an integral part cylindrical structure 91 of implant anchor 90. It is noted that implant anchor 90, shown in FIG 4C, is adapted for mounting of the drill guide assembly only from the buccal side of the mandible, as oppose to implant anchor 20, since upon insertion into the mandible only the connector from the buccal face of the mandible is available for operational connection with the drill guide assembly. It is further noted that mounting of the drill guide assembly only from the buccal side is particularly adapted for anterior teeth.
