Approved by the National Medical Products Administration (NMPA), Chunli Medical's dental product Light-cured Flowable Resin has obtained marketing authorization and been officially launched!

Product Introduction

Light-cured flowable resin is an oral restorative material that cures directly intraorally upon irradiation with an external light source. It mainly consists of a resin matrix and inorganic fillers. After exposure to an external light source, the resin matrix undergoes a polymerization reaction to form a cross-linked network structure, which uniformly encapsulates the inorganic fillers and forms a high-strength restoration.

It is indicated for the filling of Class Ⅲ and Class Ⅴ dental caries lesions.

Product Advantages

☛ High Strength: The flexural strength, elastic modulus and compressive strength of the light-cured flowable resin can meet the clinical requirements for the restoration of wedge-shaped defects.

☛Stable Performance: Both the raw materials and packaging materials of the light-cured flowable resin are imported.

☛Complete Range of Common Shades: The available shades of the light-cured flowable resin include A1, A2, A3 and A3.5.

☛Radiopacity: The radiopacity of the light-cured flowable resin is higher than that of an aluminum plate of the same thickness, enabling clinical observation of restoration effects with CT scans.

☛Excellent Flowability & Easy Operation: The light-cured flowable resin features moderate flowability with an optimal marginal filling effect and low polymerization shrinkage. Equipped with injection needles, the product is non-adhesive to dental instruments and easy to shape.

Product operation process

☛Isolation: Rubber dam isolation is recommended.

☛Cavity Preparation: Remove carious dentin and prepare a standard cavity form.

☛Pulp Protection: Apply calcium hydroxide paste for base lining when the cavity is close to the dental pulp.

☛Shade Selection: Select the appropriate shade of the resin.

☛Acid Etchant Application: Apply the acid etchant in accordance with its instructions for use, followed by water rinsing and air drying.

☛Adhesive Application: Apply the dental adhesive in accordance with its instructions for use, and perform short-time light irradiation for pre-curing.

☛Filling & Curing: Fill the cavity or defect area with the selected shade of light-cured flowable resin. For a one-step fillable cavity, irradiate with light for 20 seconds for complete curing. If one-step filling is not feasible, adopt the incremental placement technique (applying small amounts multiple times): fill the cavity/defect with a 1-2 mm thick resin layer each time, irradiate for 20 seconds per layer, and repeat the process until the ideal restoration contour is achieved.

☛Finishing & Polishing: Finish and polish the restored tooth surface.
