Why Dentists Buy Equipment They Don’t Need

Dental equipment is easy to want because you can see it and touch it. A new scanner or laser looks like progress, and patients notice it too. But a machine does not become a good investment because it is costly, advanced, or clinically impressive. It becomes a good investment when the added profit it brings justifies the money you put into it.

What happens if you do not buy it

Most owners start by asking whether they can afford the purchase. A better first question is what happens if you do not buy it. That question makes you name the problem the machine is meant to solve. It also shows you how much is really at stake.

There are three common answers, and each one leads to a different decision. If the practice would lose profitable procedures without the machine, that supports the purchase. If the machine would improve care but bring no measurable financial gain, you may still choose to buy it. In that case, call it a clinical or strategic choice and do not count on it for a high return. If the practice is not busy enough to keep the machine in use, the numbers are very hard to defend.

Count the full cost

The price on the quote is only the start. A full model includes financing, installation, training, service contracts, software fees, supplies, and the days the office loses while the team learns. It should also count the chair time the new procedure uses, because that time could have gone to other work. Add all of it up over five years, so you can compare it against the profit it adds over the same span.

Measure added profit instead of production

Production is what you bill, and it is the number vendors like to quote. What matters is the profit that is left after the new costs the machine brings. A $200,000 device that adds $300,000 in revenue may still be a poor buy. The owner needs to know what remains after added labor, supplies, lab fees, financing, and upkeep.

Why use matters most

How often the machine runs is the number that drives everything else. A device in use 90% of its available hours can have very different results from the same device in use 20% of the time. The cost stays about the same either way, but the profit rises with every hour it works. So before you buy, estimate how many cases per week you will really run, based on the patients you already see.

A worked example

Here is an example with round numbers. Say a CBCT unit costs $120,000 installed. Over five years, add $25,000 for service and software, $15,000 for financing, and $10,000 for training and lost days. The full cost over five years is about $170,000, which works out to $34,000 a year.

Now suppose each scan adds $250 in fees and costs $50 in supplies and staff time. That leaves $200 of added profit per scan. To cover $34,000 a year, the practice needs 170 scans a year, which is a little over three a week. At eight scans a week, the scans bring in about $83,000 a year against $34,000 in yearly cost, so the unit clears about $49,000 a year. At two scans a week, they bring in about $20,800, and the unit falls about $13,000 short each year. The machine and the price are the same in both cases, so use is what decides whether the purchase pays.

The order to decide in

A sound purchase follows a set order. Start with your strategy, and then find the bottleneck that holds it back. Next, design the workflow that would clear that bottleneck, and estimate how much the new tool would be used. Then run the numbers, and only after that pick the technology.

The risky order runs the other way. The owner sees the technology, buys it, and then works out how to use it. The first order treats equipment as an investment that has to earn its keep. The second treats it as spending, and the practice pays for it whether it earns anything or not.

What to do next

Before you sign the next equipment quote, write a one page memo that covers each item in the list below. Pull your own schedule data to estimate how many cases per week the machine would run. Then build a downside case at half that number and see if the purchase still works. Share the memo with your CFO or CPA, and set a date six months after install to check real use against the plan.
