Thermally stable polycrystalline constructions include a body having a polycrystalline ultra-hard phase and a plurality of empty voids. The construction includes a backside support member over at least a portion of the backside surface of the body and a sidewall support member over at least a portion of the sidewall surface of the body extending an axial distance along at least a portion of the body and at least partially covering a circumferential surface of the body. The construction has a compressive stress exerted on the body. |
