All good things come in threes
With the special Synea 900-series, W&H has designed three extra powerful speed-increasing transmission instruments.
The premium line of the Synea range – the Synea Vision – is complemented with the WK-900 LT, while the Synea Fusion portfolio is reinforced with the WG-900 LT (with light) and the WG-900 A (without light).Synea qualities at a glance
- Ceramic ball bearings for smooth operation with less vibration
- Monobloc design for better hygiene
- Heat Blocker technology that keeps the push button cool, to protect you and your patients from burns
- Compact glass rod for constant light quality and the optimal illumination of the treatment site (WK-900 LT / WG-900 LT)
- Scratch-Blocker coating for long-term value retention (WK-900 LT)
- 36-month warranty (WK-900 LT) and 24-month warranty for WG-900 LT/A)
extra tough for the removal of high-strength materials
extra precise with new head design for better bur guidance
extra easy bur changes with unique and distinctive black push-button design
Even rotary instruments designed for heavy-load applications show decreasing removal rate over time when cutting hard materials (1, 4). To keep up with cutting performance, rotary instruments need to be changed more frequently. Hence, you
will appreciate the newly designed black push-button of the Synea Power Edition. It makes the bur change noticeably easier as forces are better distributed.
extra solid chucking system with more than 20% more clamping force
With an unbelievable 20% increase in clamping force, the newly designed FG chucking system is made for heavy-load applications.
extra strong with more torque and better removal rate
extra durable with at least 20% extended lifetime
When cutting harder materials, conventional contra-angle handpieces are subject to considerable wear. Long downtimes and high maintenance costs are the result. In contrast, Synea Power Edition contra-angle handpieces are extra durable and feature an especially robust clamping system. They are less susceptible to mechanical failures and offer an incomparably longer service life of at least 20% compared to standard transmission instruments.
extra robust for less service costs
New head design and optimal ergonomics For better bur guidance the head is placed slightly higher. With the optimised shaft design, a secure grip and a perfect balance is ensured, especially in combination with the small electric motors from W&H.

HeatBlockerHeatBlocker – protects against burns
The W&H HeatBlocker technology ensures a cool push button and minimises the risk of injury for your patients. The ceramic ball integrated in the head of the contra-angle handpiece reduces friction on the push button if it is pressed unintentionally during treatment. The heat development prevented in this way not only protects you, but also your patients from burns.
