Foshan Liangya – New Resin Filler Makes a Stunning Debut

# Foshan Liangya – New Product Launch: Resin Filler Debuting with a Bang

In the field of dental restoration, innovation in materials and instruments has always been the core driving force behind the advancement of diagnostic and therapeutic standards. Recently, Foshan Liangya Dental Equipment Co., Ltd., a company that has been deeply engaged in the oral medical device industry for 15 years, officially launched a new generation of resin fillers. With their precise design, versatility across multiple clinical scenarios, and user-friendly operational experience, these fillers redefine the clinical standard for dental resin fillings and provide dentists worldwide with more efficient restoration solutions.

I. Technological Innovation: A Dual Breakthrough in Materials and Processes

The new Liangya resin filler features a comprehensive upgrade in both material selection and manufacturing processes. Its core working end is made of standard-grade stainless steel, ensuring it remains deformation-free even after prolonged use. The handle is also crafted from stainless steel and undergoes a passivation treatment on its surface, significantly enhancing its corrosion resistance. This “rigid yet flexible” design not only guarantees the instrument’s durability but also reduces hand fatigue during operation.

II. Clinical Scenarios: Comprehensive Coverage from Aesthetic Restoration to Functional Reconstruction

To meet different clinical needs, the new Liangya resin filler series has been developed with four functional categories:

1. **Anterior Aesthetic Restoration Kit**

Specifically designed for the restoration of the labial and lingual surfaces of anterior teeth, this product features a working tip only 0.3 mm thick and is equipped with an arc-shaped margin, enabling seamless gingival retraction and marginal adaptation. Clinical trials have shown that when using this kit for veneer restorations, the marginal fit error can be kept within 20 μm—significantly better than with conventional instruments.

2. **Posterior Tooth Functional Reconstruction Kit**

Adopting a combined design featuring a “cylindrical compacting tip plus a sickle-shaped lateral compression tip,” the cylindrical tip has a diameter of 1.2 mm and can penetrate deep into the bottom of cavity preparations to firmly compact the resin. The sickle-shaped tip, meanwhile, applies lateral pressure at a 45° angle, ensuring tight restoration of proximal contact points in posterior teeth. In simulated chewing tests, the fracture resistance of posterior tooth restorations repaired with this kit was improved by 37%.

3. **Minimally Invasive Wedge Defect Repair Kit**

A dual-working-end design—featuring a “flat, compression-end plus an arc-shaped forming-end”—has been developed specifically for the unique morphology of wedge-shaped defects at the cervical area of teeth. The flat end allows for vertical compression of the resin, while the arc-shaped end closely conforms to the anatomical shape of the tooth, enabling “cavity-free filling.” Clinical cases demonstrate that, after one-year follow-up, the failure rate of wedge-shaped defects restored using this system is below 5%.
