What Makes a Good Prophy Angle?
Ultimately it’s about the safety of your patient, and how comfortable it is for you to use. Here is a guideline for choosing:
How much does it splatter? This does depend on the shape of the cup, but regardless of the shape, it’s critical to use a splatter reducing angle. You don’t want to make it rain on your patient.
Does the design allow the prophy paste to enter the handpiece, ultimately damaging the machine? That’s just terrible. More paste inside your handpiece than engineering
Does it overheat? Oh man… Don’t let it burn
Does it have an exterior ridge? This is very useful for in-between adjoining teeth.
Is it vibrate-free? Your patients and you shouldn’t feel like there is an earthquake every time you are doing their cleaning.
How slim is the neck? The thinner the neck of the angle, the more visibility for you
How well does it fit your hand? You do not want to add excessive holding and stress while operating
Does it have a good grip? Same as above, it’s best if you save your fingers from pain
