Synea Straight & Contra-angle Handpieces

To make it easier to select one of our new Synea straight and contra-angle handpieces, we listened to your requirements and have now developed two new lines perfectly suited to your needs. Synea Vision: now with innovations such as special scratch-resistant coating. And Synea Fusion: a series with top quality and maximum economy.

    • Synea Power Edition: For the hardest materials

      The Synea Power Edition is especially designed for heavy-duty applications, such as the removal of decayed materials, cavities, fillings, crowns, and bridges. These new high-speed contra-angle handpieces with a unique black push-button are built extra strong and durable.

      They are the optimal solution for advanced ceramic material like zirconia that is increasingly being used in restorative dentistry. Thus, this up-to-date addition to the Synea family is the perfect complement to your existing handpiece range.

      For heavy-duty applications

      • Zirconia-based dental restorations are becoming used more commonly. However, limited attention has been given to the difficulties experienced, concerning cutting, in removing the restorations when needed.(1)
      • Dental zirconia has posed a problem in removal […] due to its high flexural strength and hardness. Attempts to section dental zirconia often result in destroying multiple burs, loss of chair time, and frustration by the dentist and patient.(3)
      • […] cutting of Zir [Zirconia] took about 1.5- and 7-fold longer than cutting of LD [lithium disilicate glass– ceramic] and L [leucite glass–ceramic], respectively.(1)

        Studies show that

        […] high cutting force will decrease cutting efficiency on zirconia, rather than improve it.(1)

        […] a higher force for cutting of Zir […] increases the damage to the diamond burs, resulting in a decrease of the total cutting depth.(1)

        […] higher force may cause more damage to super coarse burs, which may decrease their cutting efficiency over time.(3)

        The removal of zirconia restorations is a demanding procedure. Conventional contra-angle handpieces are struggling to keep up with cutting performance. Applying even more load to improve removal rate wears out the bur much faster (1, 3) and may risk thermal damage to vital teeth (2).

        With the Synea Power Edition cutting efficiency is improved without having to apply extra heavy loads.

          Extra robust chucking system for higher clamping force

          With an unbelievable 20% increase in clamping force, the newly designed FG chucking system is made for heavy-load applications.

          Multiple spray with high water flow for proper cooling

          With three enlarged nozzles smartly placed around the bur and a water flow of more than 50 ml/min, the Synea Power Edition provides an impressive cooling and cutting level.

          The integrated maintenance-free spray filter reliably prevents nozzle clogging and ensures a constant high-water quality.

          W&H Synea Power Edition contra-angle handpieces

          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.
