Dental Drilling Unit: Finding Used & Precision Hand-Controlled Tool

In summary, there is a dental drilling unit that can be used for finishing metal prototypes which is highly recommended for its precision and superior torque and rpm compared to Dremel-type rotaries. It operates using compressed air and can be found on various websites by searching for "dental handpieces". Another recommended tool for fine work is the Foredom rotary tool with a 1/3 horsepower motor.

An ME I know uses a "dental drilling unit"(his name for it) to finish metal prototypes. He bought it used from his dentist and says it's the absolute best hand-controlled tool for fine work, and recommends it to anyone who uses Dremel-type tools for their work(me) or even hobbies, and needs more precision. It uses compressed air, not electricity, and has much more torque and rpm's than Dremel-type rotaries that have almost no torque.

What is the exact name or nomenclature of this type of machine and where could I find a used one? (I have to know the correct name of it to search auction sites and dental drilling unit doesn't do it.)

Thanks for any help.

Personally, I've never heard of it called anything but a dentist's drill. Since the operation is pneumatic, I'd start with looking for that.

I really like the Foredom rotary tools. Heavy duty motors, interchangeable handpieces, very high quality. The model I have doesn't match the high-speed of a Dremel, but the 1/3 horsepower motor is awesome.

1. How does a dental drilling unit work?

The dental drilling unit is a hand-controlled tool used by dentists to remove decay and shape teeth during various dental procedures. It consists of a high-speed handpiece, which rotates a dental burr, and a low-speed handpiece, which provides a more precise and controlled movement. The dentist uses foot pedals to control the speed and direction of the handpieces, allowing for precise and efficient drilling.

2. Is the dental drilling unit a safe tool?

Yes, the dental drilling unit is a safe tool when used properly by a trained and licensed dentist. The hand-controlled feature allows for precise movement and reduces the risk of accidental damage to surrounding teeth or tissues. Additionally, the use of water or air spray during drilling helps to prevent heat buildup and keep the tooth and surrounding tissues from being damaged.

3. Can the dental drilling unit be used on all types of teeth?

Yes, the dental drilling unit can be used on all types of teeth, including permanent and primary teeth. However, the dentist may adjust the speed and pressure of the handpiece depending on the type of tooth and the procedure being performed. For example, a lower speed may be used for more delicate procedures such as root canals.

4. How do you maintain and sterilize a dental drilling unit?

The dental drilling unit should be properly maintained and sterilized to prevent the spread of infections. After each use, the handpieces should be flushed with water to remove any debris and then cleaned with a disinfectant solution. The burrs should be replaced regularly, and all parts of the unit should be inspected for wear and tear. The unit should also be sterilized using heat or chemical methods before each use.

5. Can a used dental drilling unit be just as effective as a new one?

Yes, a used dental drilling unit can be just as effective as a new one if it has been properly maintained and serviced. However, it is important to purchase a used unit from a reputable seller and have it inspected by a professional before use. Regular maintenance and replacement of worn parts are crucial to ensuring the effectiveness and safety of a used dental drilling unit.
