Parkell® Predicta ™ Bioactive stackable core material stimulates a protective layer of mineral apatite formation for core build-ups. Product Features: Its stackable (higher viscosity) properties minimizes crown prepping time, when placing larger core build-ups where stackability results in a more centralized core. Has less excess in areas that would require removal during prepping. Restorative material contains Zirconia for enhanced cuttability (helping eliminate ditching or gouging of the material when cutting around dentin). Bioactive properties releases calcium, phosphate, and fluoride ions in order to stimulate mineral apatite formatin and remineralizes at the material-tooth interface. Has a versatile, non-slumping formula that makes it ideal for creating a strong, stable core that lasts and resists flexing. Its unlimited depth of cure ensures that the deepest portions of the restoration will polymerize. Highly radiopque for easily indentifying on x-rays. Made in the USA. Includes: 5 mL Predicta Bioactive syringe and (20) 17 gauge tips. Physical Properties: Compressive Strength: 360 MPa Flexural Strength: 130 MPa Barcol Hardness: ≥ 70 Radiopacity (vs aluminum): 280% Work Time of Self-cure (@ 77° F): 1-2 minutes Set Time of Self-cure (@ 98.6° F): 5 minutes Instructions SDS Information NOTE: For flowable (low visocosity) Predicta Bioactive core material, see here.
