1) Compact Size
The head's outer diameter is only φ8.9mm x 14.1mm. The handle features a slightly curved design at the front, making it more compact and providing better visibility.
2) Compared to similar models in the factory: Compared to the C7-1, the C7-4 has a smoother curvature, making it easier to hold and use.
3) 92-Degree Head Design
This allows for a larger elevation angle, making it more convenient to use on the back teeth.
4) More Concentrated Light
The fiber optic output surface and the front of the handle are designed with concave shapes, concentrating the light at the needle tip.
5) Anti-Overheating
A dust cover is added to the mechanism to prevent water from entering during rotation and causing the head to overheat.
6) Ceramic Bearings for More Stable Lifespan
The mechanism uses ceramic angular contact bearings, improving lifespan stability.
