Foshan Liangya – Root Canal Motor with Polishing Function, 9 Programs

Sep 17,2025

The technological upgrade of the Liangya Root Canal Motor revolves around two core principles: "safety" and "efficiency." In terms of safety, the device features a built-in torque sensor and an intelligent reverse system. When the nickel-titanium file encounters resistance, the motor can trigger an immediate 0.1-second reversal, preventing instrument breakage or apical perforation. Additionally, the device boasts a wireless handheld design, significantly reducing the risk of cable entanglement.

# Foshan Liangya - Root Canal Motor with Polishing Function, 9 Programs

In the field of dental medical equipment, Foshan Liangya Dental Equipment Co., Ltd. stands out thanks to its innovative technology and practical design. The company’s newly launched root canal motor not only integrates the core functions required for root canal preparation but also innovatively incorporates a polishing feature into the device. Additionally, it offers 9 adjustable programs, providing dentists with a more efficient and precise treatment solution. The introduction of this advanced equipment marks a significant shift in root canal therapy—from single-function devices toward versatile, integrated systems—effectively addressing clinicians' dual demands for both efficiency and quality.

I. Functional Innovation: Integrated Design for Polishing and Root Canal Preparation

Traditional root canal motors are primarily used for root canal enlargement and shaping, while the Liangya root canal motor incorporates polishing functionality into the same device through technological advancements. This innovative design stems from clinical needs for smooth root canal walls—polishing helps minimize debris retention within the canal, reducing the risk of postoperative infections while also enhancing the tightness and sealing of filling materials. For instance, when treating curved root canals, the device can use its polishing function to eliminate microscopic steps created during preparation, ensuring seamless continuity of the canal’s anatomical shape.

II. Technical Highlights: Balancing Security and Efficiency

The technological upgrade of the Liangya Root Canal Motor focuses on two core principles: "safety" and "efficiency." In terms of safety, the device features a built-in torque sensor and an intelligent reverse system. When the nickel-titanium file encounters resistance, the motor can trigger a reverse motion within 0.1 seconds, effectively preventing instrument breakage or apical perforation. Additionally, the device boasts a wireless handheld design, significantly reducing the risk of cable entanglement.

Efficiency improvements are achieved through the combination of an optimized powertrain and advanced software. The device is equipped with a 16:1 reduction-ratio motor, which converts the motor’s high-speed rotation into low-speed, high-torque output for the nickel-titanium files—ensuring cutting performance while simultaneously extending the tool’s lifespan.
