At first glance, the codes and colours on rotary instruments look like a secret cipher. In fact, they are based on international standards that make selection and ordering simpler and safer. This article explains ISO 6360, the grit system and the shank standards, and why ISO 13485 and CE-MDR are not nice extras.
The ISO 6360 standard describes a uniform number system for rotary dental instruments. The multi-digit code encodes, among other things:
Anyone who reads the code identifies an instrument unambiguously, regardless of the manufacturer. This makes reordering and comparison easier.
On diamond instruments, a colour ring indicates the grit. This lets you see immediately how coarse or fine an instrument works:
| Colour | Grit | Use |
|---|---|---|
| Black / green | coarse | rapid removal, reduction |
| Blue / no ring | standard | universal preparation |
| Red | fine | finishing |
| Yellow | extra-fine | pre-polish, marginal area |
The shank determines which hand- or contra-angle piece an instrument fits. The common versions:
Rotary instruments are medical devices. Anyone who uses them on patients is liable for their suitability. Two requirements are therefore central:
Both are not voluntary quality seals but a legal prerequisite for safe use. rotatec instruments are Swiss Made to ISO 13485 and CE-compliant.
Anyone who knows the code and the standards orders more precisely and safely. The entire relevant range at rotatec is from stock and ready to ship in 48 hours.
Rotary instruments are medical devices and must be reprocessed properly: clean, disinfect and sterilise in line with the recommendations of the relevant hygiene authorities. Marking by figure and code number helps to assign instruments unambiguously, sort them and trace their use. Economically, service life counts: high-quality instruments that stay precise over many reprocessing cycles lower the cost per treatment. A clearly organised instrument management, from procurement through reprocessing to reordering, is thus a building block for quality and efficiency in the practice.
