Powder Loading: The production process begins with the careful loading of zirconia powder into the manufacturing equipment. The zirconia powder used is of high quality and specifically formulated for dental applications.


Pre-pressing (Shaping): The loaded zirconia powder is then subjected to pre-pressing, where it is compressed into a preliminary shape. This step ensures uniform distribution and compaction of the powder, preparing it for the subsequent pressing process.


Cold Isostatic Pressing (Densification): The pre-pressed zirconia powder is placed in a mold and subjected to cold isostatic pressing. High pressure is applied from all directions to further compact the powder, ensuring maximum density and homogeneity.


Pre-sintering: After the densification process, the zirconia disc undergoes pre-sintering. This step involves heating the disc at a specific temperature to partially fuse the zirconia particles together, enhancing the strength and stability of the material.


Milling: The pre-sintered zirconia disc is then machined using advanced computer-aided milling (CAM) technology. This process involves the removal of excess material, resulting in the precise shape and dimensions of the final product.


Packaging: Once the milling process is complete, the 4D Multi-layer Zirconia Discs are carefully inspected for quality assurance. They are then packaged securely to ensure their protection during transportation and storage.


The production process of 4D Multi-layer Zirconia Discs combines advanced technology and meticulous craftsmanship to create high-quality dental materials. With each step, from powder loading to packaging, strict quality control measures are implemented to ensure the final product meets the highest standards of precision, durability, and aesthetics.

Recommended design steps

A:Scanning and designing

Please scan with highly precise scanners to get accurate date ofthe restoration model.Design according to the conditions ofpatients and the doctor's requirements.


Pre-sintered zirconia material has an inherent shrinkage rateassociated with each production.The shrinkage rate must beinput into the milling preparation software to ensure theaccuracy of the C:eventual restoration.

When milling our zirconia,always follow these generalquidelines

·Please identify the incisal side at first.

·Only use sharp end mills with carbide or diamond coating.

·Do not use any restoration that has chips or cracks.Remove theunits from the disc using a handpiece with a diamond-coated bur.

·Smooth the support areas with a medium-grit rubber polishingwheel.

·Remove any residual zirconia dust with an art brush.If a wet mill is used make sure all the zirconia is completely drybefore sintering.Air dry for at least 15 minutes prior to sintering.Damp zirconia will crack if placed in the sintering oven.

D:Separating restoration and cleaning

Using technician specialized hand piece and grinder to separaterestorations from the block.Please clean up the powder onsurface and inner side of restorations with brushes.If cleaning isnot thorough,powder residues will contaminate coloring liquidwhen the dyeing is processing and the powder residues will stayon the surface and inner side of restorations after hightemperature sintering,forming white spots and thereforehaving negative effect on esthetics of the restoration.


Generally coloring is not needed for HONCHON multilayerzirconia.


Put the restoration in the crucible with zirconium beads.Thebottom of crucible should be covered by the zirconium beads.Make sure the sintering furnace is clean.

Sinter the restoration according to the recommendedtemperature (see the sintering curve at the end attachment).Recommended max heating rate:10 C per minute

Cooling should be done without temperature control in closedfurnace

Never open the furnace until temperature down to 80 C to avoidthermal shocks.

G:Grinding and polishing

Using special zirconia grinder to trim the surface of restoration.Steps:coarse grinding -fine grinding -rough polishing.


After coarsely finishing,proceed to external dying and glazing.


The production of restoration is completed.
