All the retractors in our range are made from opaque medical grade polypropylene. Having experimented with many styles of retractors we believe this material offers far greater flexibility, durability and patient comfort than metal or polycarbonate alternatives. Double-Ended Design Patented Retractors These design-patented, double-ended retractors feature extended supports to hold the lips comfortably out of the way when capturing anterior images. The C-shaped ends are ideal for front on views while the V-Shaped form improves access and visibility when photographing molars for posterior and lateral views. Each end offers a different size, making the retractors versatile for use with both children and adults.
