An apparatus for implantation of a zygomatic implant in coincidence with an implantation vector, previously derived by use of imaging and computer program facilities, wherein the apparatus comprises: a dental implantation guide comprising a guide shell and at least one dedicated dental tool (DDNTL), with guide shell being configured to support guides and to conform with and for releasable affixation to a portion of a maxillary bone, the guides having an anterior guide operative in association with a posterior guide to form a pair of guides (PRGD) which are distanced apart relative to each other, and are aligned with the vector, and which guides are further configured as concave troughs for support of a cylindrical body, which is one out of a zygomatic implant, an implantation drill (IMPDR), a preliminary drill, and the at least one dedicated dental tool (DDNTL) which includes a dedicated burr comprising: a smooth spherical head (SMSHD) configured for guidance by the posterior guide and operative as a fulcrum, a cylindrical abrasive body (CYLAB), coupled by a neck to the spherical head (SMSHD), and configured for osteotomy, a shank (SHNK) which is coupled to the body (CYLAB), whereby the dedicated burr is configured for operation in rotation and in pivotal motion about the fulcrum, for motion in a plane defined by the posterior guide and the anterior guide, to open a recess parallel to the vector in the maxilla, until seated into the anterior guide, and at least one gap, pierced through the guide shell between the distanced apart pair of guides (PRGD) and configured for release of the guide shell from the maxilla, wherein the pair of guides (PRGD) is further configured into inverted disposition by disposing of each trough of the anterior guide and of the posterior guide in diametrically opposite disposition relative to the cylindrical body, whereby a moment of forces applied about an axis perpendicular to a longitudinal axis of the cylindrical body, urges the cylindrical body into stable and firm support in the pair of guides (PRGD), whereby the cylindrical body is correctly aligned with the vector. a smooth spherical head (SMSHD) configured for guidance by the posterior guide and operative as a fulcrum, a cylindrical abrasive body (CYLAB), coupled by a neck to the spherical head (SMSHD), and configured for osteotomy, a shank (SHNK) which is coupled to the body (CYLAB), whereby the dedicated burr is configured for operation in rotation and in pivotal motion about the fulcrum, for motion in a plane defined by the posterior guide and the anterior guide, to open a recess parallel to the vector in the maxilla, until seated into the anterior guide, and at least one gap, pierced through the guide shell between the distanced apart pair of guides (PRGD) and configured for release of the guide shell from the maxilla, wherein the pair of guides (PRGD) is further configured into inverted disposition by disposing of each trough of the anterior guide and of the posterior guide in diametrically opposite disposition relative to the cylindrical body, whereby a moment of forces applied about an axis perpendicular to a longitudinal axis of the cylindrical body, urges the cylindrical body into stable and firm support in the pair of guides (PRGD), whereby the cylindrical body is correctly aligned with the vector.
