ClikTech Inc.’s Litening Rods™, made of Radel® polyphenylsulfone (PPSU) resin from Solvay Specialty Polymers USA, LLC, can replace metal rods, which are labor intensive and more costly. Thermoplastic rods made of PPSU are stiff like metal but are 75% lighter. The rods also offer easier handling due to an integrated handle grip design. They have the added benefit of incorporating a wire clip to accommodate the latest in digital sensors and work with any standard anterior, posterior, or bitewing ring. The rod attaches to a bite block receptacle, which in turn holds the digital sensor. Radel PPSU is a super-tough thermoplastic with high heat resistance, exceptional hydrolytic stability, and excellent chemical resistance. It can withstand over 1000 cycles of steam sterilization without significant loss of properties. It is inherently flame retardant and is resistant to bases and other chemicals. Radel PPSU is also compliant with ISO 10993-1 for limited exposure, non-implantable applications. Litening Rods are 1/8-in2 and five inches long and meet ISO 10993 and FDA requirements for intraoral use.
