The Adhesthetics Theca kit is comprised of four unique instruments designed by Dr. Federico Ferraris in collaboration with Hu-Friedy. It is an independent set of instruments conceived to cover the main variety of clinical phases in direct and indirect restorative dentistry in order to help clinicians to achieve predictable results and clinical excellence. The Main Shaper, the Fine Shaper, the 3D Shaper and the Direct Caliper are all made with XTS technology, a dark Aluminum Titanium Nitride (AlTiN) coating that offers superb contrast in comparison to composite materials and tooth structure. The coating is also incredibly slick, resisting the adhesion of sticky composite materials. The smooth handle is not only ergonomic and lightweight, but each instrument has its own distinct set of colour cones, making instrument identification simple. The set of four instruments includes an IMS Cassette, which prevents the instruments from being damaged during transportation and sterilization protocols.
