| 摘要 |
The invention relates to a nozzle (4) for a polishing device intended for dental treatments including a body (5) extending between a proximal portion (8) intended for being connected to a handpiece (6) and a distal portion (10), the body including a first channel (14) intended for supplying a dental polishing powder (Fa/p) and a second channel (16) intended for supplying a fluid (Ff), the two channels each being in communication with at least one respective opening (18, 20) which is in communication with the free end (12) of the distal portion (10), in which the free end (12) of the distal portion forms a tab (22) aligned with the distal portion (10) downstream from the openings (18, 20), the tab (22) being arranged spaced apart from the openings such as to at least partially disrupt the flow (Fs) formed by the combination of the dental polishing powder and the fluid coming out of the openings. |
