A self-ligating orthodontic bracket having resilient retention features comprising: a bracket body and a ligating slide (8a, 8b); said bracket body comprising: a mounting base with a concavely contoured surface suitable for attachment to a tooth; a main archwire slot formed upon the mounting base, supported by the bracket body, and sized for receiving an orthodontic archwire; a ligating slide recess positioned in the central front part of the occlusion extension of the bracket body exhibiting a wide open front end with two inwardly facing slide slots (23, 29), constructed at a gingival extension and at an occlusal extension of the bracket body; a deck including three elongated relief areas, namely a modified dumbbell channel, a lake, and a guiding path in sequence wherein the modified dumbell channel in conjunction with the elongated lake form a resilient retention feature located between the modified dumbbell channel and the elongated recess; said ligating slide comprising, at the edges, lengthwise extension arms used to selectively slide along the ligating slide recess between an open position so as to provide access to the archwire slot and a closed position that provides for a covering of the archwire slot, wherein said ligating slide comprises an outer front surface and an inner underside surface, wherein said inner underside surface of the ligating slide facing the deck of the bracket body comprises a bar rail and a cylindrical protrusion; wherein said elongated lake permits flexing of at least a portion of said resilient retention feature during the shifting of the ligating slide; wherein said modified dumbbell channel consists of a narrow channel having two wider spaced-apart circular recesses (39,42) at both ends designed to accommodate the cylindrical protrusion of the cylindrical slide, wherein the respective axis of those two circular recesses are parallel to each other and perpendicular to the deck, wherein the circular recess, remaining unmodified, acts as a slide stop to retain the ligating slide in its open position and to prevent the ligating slide from disengaging from the bracket, whereas the other circular recess, located adjacent to the archwire slot, being modified into a truncated cup-like holding circular recess secures the ligating slide in its closed position for retaining the orthodontic archwire within the archwire slot; and wherein along the modified dumbbell channel, the resilient retention feature includes a detent projection coplanar with the deck and two inward curvatures along the cup-like holding circular recess and two inward curvatures along the slide stop circular recess; wherein the guiding path runs through the deck, separating the deck into two parts, a minor part and a major part. a mounting base with a concavely contoured surface suitable for attachment to a tooth; a main archwire slot formed upon the mounting base, supported by the bracket body, and sized for receiving an orthodontic archwire; a ligating slide recess positioned in the central front part of the occlusion extension of the bracket body exhibiting a wide open front end with two inwardly facing slide slots (23, 29), constructed at a gingival extension and at an occlusal extension of the bracket body;
