Foshan Liangya – 1-Second Light-Curing Machine with Right-Angle Light Guide Rod

Nov 26,2025

Liangya's newly developed right-angle light guide rod efficiently transmits the 420–480nm blue light from LED sources to the surface of restorative materials with minimal loss. This innovative design allows clinicians to perform "direct-view procedures" without frequently readjusting the device angle, making it especially ideal for complex scenarios such as proximal cavities in posterior teeth and deep carious lesions.

Foshan Liangya – 1-Second Light-Curing Machine with Right-Angle Light Guide Rod: The Efficiency Game-Changer for Dental Treatments

In the field of dental restoration, the performance of light-curing units directly impacts the quality of restorations and the efficiency of clinical treatments. The 1-Second Right-Angle Light Guide Stick Light-Curing Unit, launched by Foshan Nanhai Liangya Dental Equipment Co., Ltd., has become a benchmark product in the dental equipment market thanks to its unique technological advantages and significant clinical value. This device not only addresses the pain points of conventional light-curing units—such as limited operational flexibility, slower curing speeds, and restricted material compatibility—but also redefines the efficiency standards for dental care through its innovative design.

I. Technological Breakthrough: Collaborative Innovation of Right-Angle Light Guide Rods and 1-Second Curing

Traditional light-curing units typically feature straight-tube guide rods, which often limit the angle of illumination when treating posterior teeth or complex cavities. As a result, dentists frequently need to reposition either the patient or the device itself, increasing both the technical difficulty and the overall treatment time. However, Liangya’s newly developed right-angle guide rod efficiently transmits the 420–480nm blue light from the LED source to the surface of the restorative material with minimal energy loss. This innovative design allows clinicians to perform "direct-view operations" without constantly readjusting the device’s angle, making it especially ideal for challenging scenarios such as proximal lesions on posterior teeth or deep carious cavities.

More notably, the device is equipped with a groundbreaking 1-second curing technology that breaks through industry bottlenecks. By leveraging a high-power LED light source delivering 1600 mW/cm² combined with an intelligent light intensity adjustment system, the device can fully cure 2mm-deep resin in just 1 second—while maintaining curing uniformity exceeding 98%. Clinical trials have demonstrated that when using this device to restore Class II cavities in posterior teeth, dentists can reduce their single-operation time by 40%, while patients experience a 60% decrease in mouth-opening fatigue. This "fast and precise" curing capability makes it particularly well-suited for pediatric dentistry and elderly patients—groups that are especially sensitive to treatment duration.
