1. Intraoral Scanning

Purpose: Capture a precise 3D model of the patient’s dentition.

Required equipment:

• Intraoral scanner (Runyes V3 PRO / Medit i700 / 3Shape TRIOS / Primescan / Planmeca Emerald / etc.)

• Calibration tool (if required by scanner)

Hardware:

• Сomputer or laptop with the necessary system requirements and installed software for an intraoral scanner: 
  Runyes V3 PRO All-in-One Mobile Cart Intraoral Dental 3D Scanner
  
  Check system requirements :
  Runyes: Minimum & Recommended Computer (PC) Specifications
  Medit: System requirements Medit Link (T-series)

Consumables:

• Scanning spray or powder (if scanner does not use true color technology)

• Intraoral scanner spare tips

Output:

• STL / PLY / OBJ files ready for design

Note: 
If the clinic does not have a scanner, the impression can be taken conventionally and scanned in a partner lab.

2. Design (CAD)

Purpose: Create a virtual model of the crown.

Required software:

• Exocad DentalCAD (Chairside or Lab version), 3Shape Dental System, or CEREC Chairside Software

• Ivoclar IPS e.max CAD library (if required by CAD software) 

Hardware:

• Computer or laptop with the necessary system requirements and installed software for CAD:
  Exocad: System Requirements

• Optional 3D mouse for modeling convenience

Consumables:

• None (software stage only)

Notes: 
If the clinic has no CAD software, design can be outsourced to a dental lab. 
The designed file (STL) will then be returned for milling.

3. Milling (CAM)

Purpose: Fabricate the crown from an IPS e.max CAD block.

Required equipment:

• Dental milling machine (wet-capable, e.g., Imes-Icore CORiTEC One / One+)

• CAM software (MillBox / hyperDENT / etc.)

• IPS e.max CAD block holder (adapter)
  Imes-Icore CORiTEC One includes 1-Fold or 3-Fold Glass Ceramic holders
  Imes-Icore CORiTEC One+ includes 6-Fold Glass Ceramic Holder

Consumables and tools:

• IPS e.max CAD blocks (shades and sizes: e.g., A2 HT C14, LT, MT, etc.)

• Diamond milling burs (designed for glass ceramics)
  for Imes-Icore CORiTEC One / One+

• T21 - 2.5 mm Grinding Tool (diamond) for Glass Ceramics, 3 mm shank

• T22 - 1.0 mm Grinding Tool (diamond) for Glass Ceramics, 3 mm shank 

• T23 - 0.6 mm Grinding Tool (diamond) for Glass Ceramics, 3 mm shank 

• Coolant fluid:

  • Use manufacturer-approved liquid:

    • imes-icore CORiTEC Mill & Grind Cooling Liquid

  • Replace every 2 weeks or sooner

Maintenance:

• Calibration Blocks - for Imes-Icore CORiTEC One 
• Calibration Blanks - for Imes-Icore CORiTEC One+ 
• Kroeplin E110D Calibration Tool for Milling Machine
• Spindle maintenance kit - included in every machine

Check the maintenance booklet to get more details - Imes-Icore: Maintenance Booklet

If no milling unit: 
Send STL to a lab that mills IPS e.max CAD; they can return the “blue stage” restoration for crystallization in-clinic.

4. Post-Milling Finishing

Purpose: Refine the milled surface and remove connectors.

Required tools:

• Fine-grit diamond rotary instruments

• Ceramic polishing burs

• Turbine, handpiece, micromotor

• Ultrasonic cleaner

Consumables:

• Alcohol wipes or cleaning solution

• Disposable gloves and brushes

Notes: 
Perform gentle finishing only; excessive pressure can cause microcracks.

5. Crystallization (Furnace Stage)

Purpose: Strengthen and achieve the final shade of the e.max CAD crown.

Required equipment:

• Ceramic furnace capable of crystallization (Dekema AUSTROMAT® 624i Dental Firing Furnace)

• Crystallization tray and pins

• Dekema Firing tray, set (Art. No.106490) - Included with the Dekema Austromat 624i

• IPS e.max CAD Crystallization Tray / Pins

• IPS Object Fix Putty or Flow (to support restoration during firing)

Consumables and Tools:

• IPS e.max CAD Crystall/Glaze Paste or Spray

• Cleaning brush

• Tweezers SKU: 105236 - Included with the Dekema Austromat 624i 

Firing parameters:

• 840–850 °C / hold 25–30 min (refer to manufacturer program)

Maintenance:

• Furnace calibration kit (for temperature verification)
• CALIBRITETM fire set SKU: 101817-01  - Included with the Dekema Austromat 624i 
• CALIBRITETM fire wire SKU: 101821-01  - Included with the Dekema Austromat 624i 

If no furnace: 
Send the milled “blue stage” crown to a partner lab for crystallization and glazing.

6. Staining and Glazing (Optional)

Purpose: Customize color and achieve gloss.

Required materials:

• IPS e.max CAD Glaze Paste or Spray

• IPS e.max Stains

• Brushes and mixing palette

Equipment:

• Same furnace as above

Consumables:

• Isopropyl alcohol (for cleaning)

• Glazing firing pins and tray paper

Note: 
Keep stains and glaze materials refrigerated when not in use.

7. Try-In and Surface Conditioning

Purpose: Check fit and prepare the crown for bonding.

Tools and consumables:

• Fit checker or disclosing material

• Micro-brushes

• Sandblaster with Al₂O₃ ≤ 50 µm (1–2 bar)
