The D17-S is meant for rotary work in general dental surgery, where a straight piece suits jobs done with the handpiece held in line with the hand. The body runs straight from the tail to the front end, and the navy hairline near the tail is the only mark of colour, which keeps the whole piece easy to read at a glance.
In restorative rooms and hospital clinics, a straight handpiece is taken up and put back many times in one day. The hairline gives a team a quick cue on a tray of plain metal, and the SOCO logo on the side lets the maker's name be read without turning the piece. When a session ends,s each handpiece goes back to its place, and the thin navy band makes a missing piece easy to notice. Staff who move between rooms know the piece by its line and band so that they can hand it along the chair without comment.
The words inner channel straight head are the only technical wording in the title. Nothing further comes with them, so a team that wants a figure for its records can request it through Medigear. Speed, ratio, bur size, spray type and air supply all fall under that, and none is given.
Practice managers and dental assistants handle purchasing. One code, D17-S, names the handpiece. Rooms fitted with this piece can share that code, which consolidates reorders to one line and keeps trays matched across the building.
