Abstract:
1. A dental surgical guide comprising: a template material configured to be coupled onto a portion of a patient's mouth; and a dental drill guide positioning ring attached to or integrally formed within the template material in a region to be drilled for installing a dental implant, the dental drill guide positioning ring comprising: a substantially cylindrical body defining a longitudinal axis, an inner surface defining a substantially cylindrical central opening, and an upper end interfacing surface; and one or more flange retention elements extending inwardly from the inner surface of the cylindrical body that receive a complementary drill guide, the one or more flange retention elements being axially spaced from the upper end interfacing surface along a common plane perpendicular to the longitudinal axis, wherein the temporary retention axially couples the complementary drill guide along their longitudinal axis with respect to the dental drill guide positioning ring by disposing the one or more flange retention elements into the annular recess of the complementary drill guide, the axial coupling being achieved independently of a rotational motion of the complementary drill guide relative to the dental drill guide positioning ring, the one or more flange retention elements permitting the complementary drill guide, in an installed configuration, 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.
