Why do the cost of spare parts determine the true cost of a dental treatment unit?

Why are spare parts and their cost important when purchasing a dental treatment unit?

Investing in a dental treatment unit is always a significant decision for a dentist or dental hygienist. It’s not just about acquiring equipment – it’s about securing a daily work tool that must perform reliably, every single day. While attention is often focused on the initial purchase price, less consideration is given to the total cost over the lifetime of the unit. Let’s take a closer look.

For example, consider a dental treatment unit priced at €18,000 (excl. VAT), or €22,590 (incl. 25.5% VAT). When financed through a five-year leasing agreement, the cost is distributed evenly:

€348.30 per month (excl. VAT)
€437.12 per month (incl. 25.5% VAT)

On a monthly basis, this may seem quite reasonable. For most clinics, such a cost can be comfortably covered through normal patient flow. Leasing also offers predictability – expenses remain stable, and there are no surprises from a financing perspective.

However, this is where many make a critical mistake: focusing solely on the monthly payment.

In reality, the true cost of a dental treatment unit is largely determined during its use – and in particular by the cost of maintenance and spare parts.

Maintenance and spare parts – the true costs emerge in use

No device operates flawlessly without regular maintenance and the replacement of wear-and-tear parts. In addition, MDR regulations require that a dental treatment unit is serviced according to the manufacturer’s instructions – otherwise, responsibility for the device’s performance shifts to the user.

It is also common for margins in equipment sales to be shifted to after-sales services. In practice, this means that the initial purchase price is kept attractive, while profits are generated later through maintenance. If this is not recognized in advance, servicing costs can become a significant expense.

Annual maintenance for a dental treatment unit can, at its lowest, be around €1,000–€1,200, depending for example on the location of the service technician. If the technician has to travel from further away, travel costs will increase the price even more.

At the other end of the spectrum, the same annual maintenance can cost as much as €2,500–€3,500. In practical terms, this means an additional cost of roughly €300 per month. Over five years, this can result in paying back any “savings” made on the purchase price – purely through maintenance.

What happens when a dental treatment unit breaks down?

All dental treatment units contain a large number of generic components – meaning parts that are similar regardless of the manufacturer. There are only a limited number of component manufacturers, so technically equivalent parts are often very similar. However, prices can vary significantly depending on the supplier. This becomes especially evident when service is required.

Servicing a dental treatment unit is not just about labor – it often includes the sale of spare parts. When a service technician arrives on site, the fault is identified and typically resolved quickly – in practice, this usually means replacing a component. If the required part is not immediately available, the repair may be delayed. The part must then be ordered from the manufacturer, which can lead to longer waiting times and sometimes multiple service visits.

The pricing of spare parts can vary surprisingly widely, and this directly affects the total cost of maintenance. The same component can be priced very differently by different suppliers, even if it is essentially the same product. A few examples illustrate this:

• Suction hoses (5 m + suction tips): approximately €500 (excl. VAT)
  → the material cost of comparable components is significantly lower
• Bottle water container: approximately €300 (excl. VAT)
  → a specialized product, but pricing varies considerably

The purpose of these examples is not to criticize individual suppliers, but to highlight an important point:

Maintenance has a significant impact on the true cost of a dental treatment unit.

This is why some units may appear affordable at the time of purchase, while the total cost only becomes clear during use. Ultimately, it comes down to transparency and comparison. When you understand what maintenance actually includes and costs, it becomes much easier to evaluate the full picture – and avoid unexpected expenses.
