── Advanced CAD / CAM Zirconia Technology

CAD / CAM zirconia technology has become one of the most widely used solutions in modern digital dentistry. With the help of professional dental software and advanced dental equipment, dental laboratories can efficiently produce highly accurate zirconia restorations.

We can provide a complete CAD/CAM Zirconia system: using an intraoral scanner to accurately acquire information from the patient’s mouth and generate STL, OBJ, and PLY format files; importing the patient information file into EXOcad or 3Shape dental design software to set up customized prostheses and generate STL files.After processing, hyperdent.millbox.worknc and other files are used to generate an nc file, which is then imported into a zirconia milling machine to sculpt the pre-crystallized zirconia into the shape of a tooth. The tooth is then placed in a sintering furnace for crystallization until it is fully crystallized. A glaze is then applied to the surface of the restoration, and the restoration is placed in a porcelain furnace for crystallization. Finally, the restoration is polished to obtain the final restoration.

Our solutions are designed to deliver high precision, stable performance, and reliable material compatibility, making them ideal for dental laboratories seeking advanced digital production capabilities.

Workflow
──

A typical CAD / CAM zirconia restoration workflow includes the following steps:

Step 1 – Digital Scanning

Dental data is obtained by scanning with an intraoral scanner or a desktop scanner.

Step 2 – CAD Design

The restorations were designed using professional dental CAD software such as EXOCAD or 3shape..

Step 3 – CAM Milling

The restoration was obtained by milling pre-crystallized zirconia using a dental milling machine..

Step 4 – Zirconia Sintering

The milled restoration is placed in a sintering furnace and sintered at a high temperature of 1450-1550℃ to achieve a fully crystalline state..

Step 5 –Polishing and glazing

After sintering, the surface of the restoration is coated with glaze and then placed in a porcelain furnace to crystallize, achieving the final restoration effect.

Frequently Asked Questions
──

1.It has higher iocompatibility and less rejection by human tissues.

2.The aesthetic effect and simulation level are high, and its color and effect are closer to real teeth.

3.While maintaining aesthetic appeal, it also boasts high toughness, bending strength, and light transmittance.

4.Compared to traditional processes, zirconia requires a shorter cycle time, thus improving efficiency.

Doctor-side issues: unclear shoulder on the prepared tooth, undercuts, and insufficient preparation space, which can directly lead to poor fit and inaccurate margins

Technical issues in the lab: poor cutting accuracy and data scanning distortion can lead to crown shape deviation and poor marginal fit;

Technician-side sintering issue: unstable sintering shrinkage can cause overall deformation of the crown and edge warping.

① Insufficient space for tooth preparation and a crown that is too thin can easily fracture under force

②The occlusal high point is not levelled, causing long-term stress concentration, leading to crown fracture.

③ Wrong material used: high-transparency zirconia applied to the load-bearing area of posterior teeth, strength mismatch;

④ If sintering is incomplete, there may be microcracks inside the zirconia block, which can easily fracture later.

⑤The tooth design is inadequate, and after the crystallisation is complete, excessive grinding leads to invisible cracks
