Embodiments of the invention relate to PDCs including at least one thermally-stable PCD body disposed at least partially within a substrate, and methods of fabricating such PDCs. In an embodiment, a PDC comprises a substrate including a at least one substrate recess formed therein, and at least one thermally-stable PCD body including an upper surface, a back surface, and at least one lateral surface. The at least one thermally-stable PCD body is at least partially received by the at least one substrate recess. Other embodiments include applications utilizing the disclosed PDCs in various articles and apparatuses, such as rotary drill bits.
