Description
Fast, Efficient Gross Reduction and Simultaneous Finishing
The TDA ’s spiral-channel design allows for rapid, non-traumatic gross reduction and also reduces the need and time for separate finishing.
Here’s why. The blade-like channel edges of the TDA increase cutting speed by chipping enamel and dentin away followed by the immediate abrasive action of the diamond particles which smooth the fresh cut surface.
| Self-Removal of Debris The spiral-channel design of the TDA directs a “turbo” flow of cool, lubricating water spray from the high-speed handpiece through the spiral channels to flush away debris and prevent clogging. This feature helps reduce drag on the handpiece and result in more rapid and efficient tooth reduction. (Fig. 2&3) |

| Rapid Heat Dissipation: Less Tooth Trauma The opposing spiral channels are essential to creating cooler cutting. When the TDA is activated with a high-speed handpiece the rotational forces recover the water spray and convey it to the working point along the spiral channel groves. This allows longer contact of the cooling spray with the tooth and the instrument, thereby creating a more efficient thermal exchange. The result is cooler cutting less tooth trauma and improved diamond life. |
