From Tom Hedge at dentalblogs.com
purchased the original Isolite and rarely used it due the bulk of the unit and the separate fiber optic cord and light source. These problems have been solved with the new i2. This device controls illumination, retraction, and isolation. It is lightweight and easy to insert in the patients mouth. The amazing thing is that my assistant often sits and watches me do a procedure. There is nothing for her to do. The device requires some installation and sells for $1495 from www.isolitesystems.comChairside CAD/CAM : dentalblogs.com.
