Profile: BioTech One, Inc focuses on the research & development of bio-resorbable and metal implantation systems and medical monitoring instrumentations. Our product Korlex-GR™ is a newly developed dental material mainly composed of taolin, fiber, and astringent. It effectively retracts gingiva after being injected into sulcus through an injection gun. The staying time of viscous Korlex-GR™ in the sulcus depends on the thickness of the gingival and the health condition of gingival. Generally, the staying time of Korlex-GR™ ranges from 0.5 min to 2 min. After the operations, this product can be washed away by water spray completely. Further, air spray is utilized to dry the sulcus. Dental impression can then be processed without affecting the precision of dental hydrocolloid impression material & the solidification of polyether.
