Dental treatment chair assembly

摘要

This disclosure relates to improvements in a dental treatment chair assembly including a unit table having various instruments attached thereto in combination with a unit arm mechanism. The assembly is so constructed that the unit arm mechanism is made slidable in the direction of the mechanism crossing (preferably at right angles with) the body axis of the chair. Such construction makes it possible to meet the convenience of both a doctor and a nurse in their operation of the instruments in dental treatment.
