amalgam

Representative of metal materials. In 659 AD, the first national pharmacopoeia "Xinxiu Materia Medica" contains a record of filling teeth with amalgam, which is more than 1,000 years earlier than in Europe. The ancient Chinese dental medical technology is really powerful!

Advantages: It has strong compressive strength, can withstand chewing friction, and has stable performance.

Disadvantages: silver gray, which is far from the color of natural teeth, is not very beautiful; and contains mercury, which has a higher potential for toxicity and risk of release in the body.

Composite resin

The representative of non-metallic materials is a polymer material, based on acrylic resin, adding glass, quartz and other particles for strengthening purposes.

Advantages: The color is close to that of natural teeth and does not change color. It has strong adhesion to teeth, and there is no need to grind the teeth too much during use.

Disadvantages: The compressive strength and wear resistance are not as good as amalgam, and the service life is not as long as amalgam.

Glass ionomer cement (GIC)

Also known as polyalkene ester cement, it is a traditional ionic polymer. It can be placed in the cavity without the use of adhesives.

Advantages: safe, with excellent physical and chemical properties, easy to use, beautiful appearance.

Disadvantages: The fracture strength, toughness and durability are all weak.

Improved GIC (Innovative Ionic Polymer)

Improve the properties of traditional ionic polymers, and enhance the ability to resist fracture, wear and corrosion.

The modified GIC formula includes:

·Resin modified glass ionomer cement (RMGIC)

·Mixed ion cement (double curing and triple curing)

·Enhanced GIC

·Bioactive glass ion
