The Clock Concept
The A~flexX Assit Arm was designed to fully utilize the clock concept. This third arm is made for either the right or left handed operator. The A~flexX frees up your non-dominate hand which allows you to use proper indirect vision.
The clock concept is designed for dental professionals to be in a position that allows for adequate direct or indirect vision while using a mouth mirror. Recently dental care providers such as dental hygienists use loupes. Loupes are magnifying glasses that force the dental practitioner into an ergonomically correct position. In wearing loupes the practitioner is forced not slouch while sitting. An eye hand distance is measured for each practitioner to allow for the best magnification possible. There has been some progression in understanding and researching proper dental ergonomics.
