It provides four key advantages: It keeps the distance ratios between operating zone and the two dental unit modules constant; It allows patient repositioning without having to move the operating light in that its beam remains pointed at the oral cavity; There is a much easier-to-use space around the tilted backrest compared to that provided by a chair without the sliding function; It maintains patient comfort. A key contribution to the ergonomic set-up also comes from the patient chair, the shaping and synchronised movement of which again optimises the operating space available to medical personnel. Asymmetric shaping of the lumbar area of the backrest and an offset backrest-seat joint provides the dentist with an unhindered approach to the patient.
