First of all, congratulations and good luck on your new endeavor! Starting a new dental practice is a tremendous challenge, but also an exciting opportunity, with the potential for a lifetime of rewards.
Of course, there is a whole host of considerations to keep in mind and details to attend to when planning a start up. Books have been written on the subject. Rather than try to cover everything here, we’re going to focus on equipment.
In any start-up, cash is king, so be careful about how much you spend and on what.
Will custom granite counter tops in your lab bring in more patients than Formica™? Will patients even see them? Avoid the temptation to purchase too many "wants." Rather, focus on what you actually need to practice dentistry first. Once you have cash flow, that is when you spruce up your new practice.
You’ll need a good compressor and central vacuum. You’ll need x-rays and a sterilizer. You’ll need chairs, units, lights, handpieces, and instruments. That’s about all you really need to practice dentistry. Everything else is window dressing that may make dentistry easier or more enjoyable, but isn’t required by any means.
To equip your operatories, you can get great new equipment with a great warranty without breaking the bank. One of the reasons we carry brands like Beaverstate and DCI is the tremendous value they offer. Pricing on these brands can be less than ½ of the big brands, without sacrificing quality.
Used equipment can sometimes help you save as well, but be careful about from whom you purchase. Make sure the company will stand behind the equipment and have done a quality job of refurbishing it. A new coat of paint can make a worn out unit look good, but without proper rebuilding, it may be a lemon. We’ve worked with many practices in the past using a mix of new and used equipment successfully. Our equipment specialists will be happy to discuss any particular equipment you may be considering.
Depending on where you are located, on site support may be difficult or expensive in your area, in such a case, you should look to equipment you can service on your own more readily. Most of the 2nd tier brands (Beaverstate, DCI, Engle, Forest, Marus, etc.) will provide a wide range of available sources for parts and are comparatively easy to work on. Older (pre-2000) A-dec units will also fit into this category, but again, be mindful about purchasing used equipment from a reputable company who does a good job of properly refurbishing.
Most importantly, starting up will give you a great chance to start educating yourself before you open your doors. Our DIY approach to equipment installation and maintenance can provide a great foundation for you and your practice. Independence often starts with installing your own equipment and only improves from there.
Or course, our Practice Tips newsletter is replete with information to help you gain independence. We've spent over 8 years compiling helpful information to help keep you up and running independent of expensive service calls. And it's not just repairs or service, there are also issues on maintenance, equipment features, and practice management (like the issue you’re reading now). In particular, check out Practice Tips #86, #69, and #38 all of which discuss installation of particular pieces of equipment.
When it comes to specific designs or types of equipment, trust yourself and your own experience. Have you already worked as an associate or have you taken over an old practice? In either case, did you notice anything about the equipment you were using? Were there things about it you found helpful? Things about it you really disliked? Your own experience and the preferences you've developed should be paramount in your decision making process.
Not only does American dental offer a full library of resources for you, we also offer a vast array of replacement parts for all the aforementioned brands and our knowledgeable techs are here to support you with free remote technical support on any equipment and parts we sell.
A lot of the above applies equally to replacing old equipment in an established practice as well. When you’re empowered with the knowledge we provide, you are equipped to save.

Our goal at American Dental has always been to empower you and your staff. We do this by sharing tips and tricks for easy equipment repair. The reality is that knowing just a little bit about your equipment and its components can help you reduce downtime and costs in your practice. This month, we’ve put together a handy glossary of some common dental equipment terms to help you cut through the “equipment speak.” Our hope is that this will assist you in identifying parts or translate what your dental technician is telling you. Enjoy!
Anti-retraction: This valve only allows flow in one direction— usually applies to water, but vacuum lines often have anti-retraction valves. It may also be referred to as a “check valve.”
Asepsis: Equipment surfaces that are easily cleaned and contain a minimum number of grooves or surface irregularities that can trap bacteria-laden debris.
Barb: A serrated fitting used to keep tubing in place. Tubing is slipped over the barb, followed by a plastic sleeve placed over the tubing to keep it in place. Most barbs in dental units come in one of two sizes: small (1/16" o.d.) or large (1/8" o.d.) for use with air and water supply lines. Barbs can be used on large vacuum lines. As they are under vacuum, vacuum barbs are not used with sleeve clamps in that application.
For more information on barbed fittings, check out Practice Tips #5 and #32.
Chuck: A hollow cylinder that holds a bur in a handpiece. Manual chucks on high-speed handpieces can be easily replaced and are available from American Dental Accessories.
For more information on chucks and handpiece components, check out Practice Tips #22, #63, #66, and #90.
Compression Fitting: Another type of fitting to hold tubing in place. A compression fitting includes a connector to which the tubing attaches, a plastic sleeve that compresses (squeezes) the tubing, and a nut that forces the sleeve to compress. As the nut is tightened on the fitting, the sleeve is compressed onto the tubing securing it in place. Compression fittings are most often used for larger tubing, 1/4" o.d. or 3/8" o.d.
For more information on compression fittings check out Practice Tips #5 and #32.
D.I.S.S. (Diameter Indexed Safety System): This is a standardized system to keep nitrous and oxygen lines separate. The oxygen and nitrous lines have been standardized to different sizes to keep from mixing them up. This is a VERY important safety feature, so you provide proper oxygen amounts to the patient when necessary.
Gasket: A polymer component designed to seal between two (usually rigid) surfaces. A gasket can have any shape or cross-section. Note that o-rings can be used as gaskets, but they conform to a specific shape and cross-section. Meaning an o-ring could be referred to as a gasket, but a gasket is not necessarily an o-ring.
HP: Abbreviation for a dental handpiece or precision dental rotary instrument/drill. HP can also be used to abbreviate Horse Power. In dentistry, this would only be in the context of a compressor or vacuum motor.
HVE: Abbreviation for high volume evacuator, also known as high speed suction or large diameter aspirator. Standard HVE's fit on 1/2" i.d. tubing and have a 7/16" i.d. opening to accept tips.
ID or OD (id/od): Abbreviation for inside or outside diameter measurements. These are the distances from one side of a circular object (e.g. tubing) to the other side; measured through the center. For some common diameter sizes for convenient comparison, see our online diagram.
Junction Box: Can be used to refer to the main (master) valves and regulators that control the air and water flow to the dental unit or the box used to cover the aforementioned valves and regulators. Junction boxes are sometimes referred to as “utility centers.”
For more information on junction boxes, check out Practice Tips #3, #23, and #73.
"Midwest" or "Borden" Style: "Midwest" style handpieces or connectors are the most common type of tubing connection used in the United States. Midwest-style handpieces connect to 4 or 5-hole handpiece tubing. Even though they attach to 4-hole tubing, many Midwest-style handpieces will have only 2 holes, any extra holes are simply not used & should be deactivated at the unit. "Borden" style tubing and connectors have only 3 holes. Borden-style handpieces may have 1, 2, or 3 holes, but will connect to all 3-hole tubing. This type of connector is most commonly used outside of the United States.
For more explanation on these connectors and other handpiece connectors, check out Practice Tips #36.
Momentary Valve: A spring-loaded toggle valve that returns to the "off" position when released.
For more on toggles, check out Practice Tips #19.
MPT or FPT: Abbreviation for male or female pipe thread. Threads placed onto a pipe with an inside diameter (i.d.) as listed. Note that the size listed refers to the pipe, not the threads. Thus a 1/2" FPT is a female thread placed on a 1/2" i.d. pipe. As the pipe diameter needs to be consistent, this makes the diameter of the thread much larger, approximately 3/4" in this case.
For more on pipe threads, see Practice Tips #5 and our online size diagram.
OEM: The original equipment manufacturer's part number.
O-ring: A circular object with a circular cross-section made of a flexible material (usually some sort of synthetic rubber). O-rings are used to seal between two surfaces or to hold different rigid components together. Sometimes they can serve both purposes at the same time.
If you need a replacement o-ring, American Dental offers an online size diagram for the most commonly used sizes. Print it off and compare your o-ring to the diagram to choose the correct one.
P.S.I.: Abbreviation for pounds per square inch. It is a unit of pressure measuring force. In the dental unit, there are gauges to indicate the handpiece drive air pressure in P.S.I. (pounds per square inch). You’ll also find valves that regulate the air pressure going to your dental unit in your junction box or utility center. Dental units and handpieces require specific air and water pressure to function properly, typically a 2:1 ratio of air and water.
For more information on the correct P.S.I. for your dental unit check out Practice Tips #3.

Relieving Valve: When referring to a toggle, “relieving” means that the toggle valve allows the air to be exhausted from around the toggle when switched to the "off" position. This is required when the switch is providing air to another valve (e.g. master) to allow it to turn on. Note, that this type of valve will only have air flowing through it, even though it may be used to turn water off and on.
For more on toggles, see Practice Tips #19
SE: Abbreviation for a saliva ejector, also known as slow speed suction or low volume suction. It has a small diameter aspirator.
