Screw appliances

Similar to spring appliances, there is such a wide variety of screws that the practitioner must quite often leave the selection of the most suitable screw for a particular function to the technician. This comes about as available space, distance of traverse etc., all have to be taken into consideration during appliance design. New screw designs appear on the market regularly, and Sheffield Orthodontic Laboratories Limited are continuously updating their selection to keep pace
with new developments. Any make of screw will be obtained upon request.
