Do you know how a zirconia crown is born?

In the era of digital dentistry, a zirconia restoration is no longer the product of hours of manual waxing and casting. Instead, it is born through a fully digital, precisely controlled workflow — one that the SK Series five-core-machine solution has made faster, more accurate, and more predictable than ever before.

From Digital Impression to Final Crown: The Five Core Stages

The SK Series connects five core machines into one seamless digital workflow, each responsible for a critical step in the journey of a zirconia crown.

1. Intraoral Scanning — Capturing the Digital Impression

The journey begins in the patient's mouth. An intraoral scanner captures a high-precision 3D digital impression in minutes, eliminating the discomfort and distortion of traditional impression materials. This digital model becomes the single source of truth for every step that follows.

2. CAD Design — Shaping the Crown Digitally

The digital impression is imported into CAD software, where the dental technician designs the crown anatomy, occlusal contacts, and marginal fit with micrometer-level control. The design can be reviewed and adjusted before any material is touched, saving time and reducing remakes.

3. CNC Milling — Machining the Zirconia Blank

The finished design is sent to a high-precision milling machine. The SK Series milling unit carves the crown from a pre-sintered zirconia blank with sub-millimeter accuracy, ensuring consistent wall thickness and precise marginal adaptation.

4. Sintering — Densifying the Zirconia

The milled crown is then placed in a sintering furnace, where controlled heating and cooling transform the soft, chalk-like zirconia into a dense, high-strength ceramic. Precise temperature curves ensure the restoration reaches its full flexural strength and translucency.

5. Staining and Glazing — Adding Life to the Crown

Finally, the sintered crown is characterized with stains and fired again in a glazing furnace. This final stage gives the restoration its natural color, texture, and luster, matching the patient's adjacent teeth.

Key Advantages of the Digital Workflow

Why Digital Matters

• Speed: A crown that once took days can now be delivered in hours.
• Precision: Digital capture and milling reduce fit errors and remakes.
• Consistency: Programmed workflows deliver repeatable results every time.
• Patient experience: Fewer visits, less discomfort, better outcomes.
