Foshan Liangya 1-Second Light-Curing Machine: Right-Angle Light Guide Rod Makes Curing Posterior Teeth Easier

Oct 31,2025

The core technology of the Foshan Liangya 1-Second Light-Curing Machine lies in the combination of its LED light source system and pulse control technology. The device features a high-power 5W LED lamp, enabling deep curing of a 2mm resin layer within just 1 second, with a stable light intensity maintained between 1600–2000 mW/cm².

Foshan Liangya 1-Second Light-Curing Machine with Right-Angle Light Guide Rod Makes Posterior Tooth Curing Easier

In the field of dental restoration, resin fillings in posterior tooth areas have long posed a challenge for clinicians due to their hidden locations and limited operational space. Traditional light-curing devices often suffer from insufficient light-guiding angles, frequently requiring clinicians to repeatedly adjust the light source position—resulting in inefficient curing and even causing microleakage along the resin margins. However, Foshan Liangya Dental Clinic has introduced a 1-second light-curing unit paired with a right-angle light guide. Through innovative optical design and functional enhancements, this advanced system delivers a more precise and highly efficient solution for restoring posterior teeth.

Technological Breakthrough: Collaborative Innovation in 1-Second Curing and Right-Angle Light Guidance

The design of the right-angle light guide rod represents another major innovation of this system. Traditionally, when illuminating posterior tooth areas, the device had to be tilted at an angle greater than 45° to reach the bottom of the cavity. However, Liangya’s unique right-angle light guide rod features a 90° bend, enabling the light beam to project perpendicularly onto the treatment surface. For instance, when treating the mesial proximal cavity of the second molar, dentists can now complete the curing process without adjusting their hand-held angle—reducing the procedure time from the conventional 15–20 seconds down to just 3 seconds. Additionally, the uniformity of light exposure is improved by 30%.
