ABSTRACT:
A maintenance-free dental prophylaxis angle includes a one-piece body including a sleeve and a head. The sleeve and head define intersecting bores. A drive assembly, comprising a drive gear and a bushing, is force fitted in the sleeve. A one-piece driven gear is received in the head bore to be driven by the drive assembly. The driven gear includes an upper bur tube, a gear part, and a lower shaft. The gear part of the driven gear rests on an upper face of a boss in the head, the boss forming a thrust bearing for the driven gear. Intersecting bores in the boss form part of a lubricant circulating system. A metal cap is force fitted in the head bore to close the head bore and retain the driven gear in place in the head. A dental tool is connected to the bur tube of the driven gear, and forms a seal with the cap.
