A dental surgical guide comprising: a template material configured to be coupled onto a portion of a patient's mouth; a drill guide positioning ring attached to or integrally formed within the template material in a region to be drilled for installing a dental implant; and a complementary drill guide, wherein the drill guide positioning ring comprises: a substantially cylindrical body defining a longitudinal axis, an inner surface defining a cylindrical central opening, and an upper end interfacing surface; and one or more flange retention elements extending inwardly from the inner surface of the substantially cylindrical body to receive the complementary drill guide and being spaced from the upper end interfacing surface along a common plane perpendicular with respect to the longitudinal axis, each one of the one or more flange retention elements comprising: an upper transition surface that tapers away from a top surface of the flange retention element; and a lower engagement surface that tapers away from a bottom surface of the flange retention element that is opposite the top surface and provides a predetermined resisting force to temporarily retain the complementary drill guide within the drill guide positioning ring, each of the one or more flange retention elements being designed and constructed to resiliently deflect away from the longitudinal axis of the body to accommodate a tapered insertion end of the complementary drill guide and rest in an interfacing recess of the complementary drill guide, wherein the temporary retention axially couples the complementary drill guide along their longitudinal axis with respect to the drill guide positioning ring by disposing the one or more flange retention elements substantially constantly spaced from the upper end interfacing surface into the annular recess of the complementary drill guide, the axial coupling being achieved using the one or more flange retention elements independently from a rotational motion of the complementary drill guide relative to the drill guide positioning ring, the one or more flange retention elements permitting the complementary drill guide to rotate within the dental drill guide positioning ring without disengagement by axial separation of the complementary drill guide from the dental drill guide positioning ring. a substantially cylindrical body defining a longitudinal axis, an inner surface defining a cylindrical central opening, and an upper end interfacing surface; and one or more flange retention elements extending inwardly from the inner surface of the substantially cylindrical body to receive the complementary drill guide and being spaced from the upper end interfacing surface along a common plane perpendicular with respect to the longitudinal axis, each one of the one or more flange retention elements comprising: an upper transition surface that tapers away from a top surface of the flange retention element; and a lower engagement surface that tapers away from a bottom surface of the flange retention element that is opposite the top surface and provides a predetermined resisting force to temporarily retain the complementary drill guide within the drill guide positioning ring, each of the one or more flange retention elements being designed and constructed to resiliently deflect away from the longitudinal axis of the body to accommodate a tapered insertion end of the complementary drill guide and rest in an interfacing recess of the complementary drill guide, wherein the temporary retention axially couples the complementary drill guide along their longitudinal axis with respect to the drill guide positioning ring by disposing the one or more flange retention elements substantially constantly spaced from the upper end interfacing surface into the annular recess of the complementary drill guide, the axial coupling being achieved using the one or more flange retention elements independently from a rotational motion of the complementary drill guide relative to the drill guide positioning ring, the one or more flange retention elements permitting the complementary drill guide to rotate within the dental drill guide positioning ring without disengagement by axial separation of the complementary drill guide from the dental drill guide positioning ring. an upper transition surface that tapers away from a top surface of the flange retention element; and a lower engagement surface that tapers away from a bottom surface of the flange retention element that is opposite the top surface and provides a predetermined resisting force to temporarily retain the complementary drill guide within the drill guide positioning ring, each of the one or more flange retention elements being designed and constructed to resiliently deflect away from the longitudinal axis of the body to accommodate a tapered insertion end of the complementary drill guide and rest in an interfacing recess of the complementary drill guide,
