Polyisoprene is a synthetic rubber material that has several advantages when used as a dental dam material. One of the main advantages is that it is non-latex, making it an ideal choice for patients who have allergies to latex. Additionally, polyisoprene is biocompatible, meaning it does not cause an adverse reaction with living tissue.
It is also strong and tear-resistant, providing a reliable barrier between the treatment area and the rest of the mouth. Finally, polyisoprene is elastic, allowing for easy placement and a comfortable fit for the patient. Overall, polyisoprene is an excellent choice for dental dams due to its biocompatibility, strength, and elasticity.
