The Isotron dental drill unit is the result of a year-long work carried out in collaboration with Eurodent to define a product of unprecedented characteristics in terms of ergonomics, practicability and hygiene. The unit has a balanced-arms instrumentation with easy side movements of the manipolo; it features computerised controls and an integrated-pedal control system. Maximum integration of dental drill and chair is ensured by the use of a same base with no shunt boxes. The chair has a steel structure and polyurethane linings; the chair movements are through independent motor reducers operating a recirculating ball bearing for smooth and noiseless changes of position.
