What processes does Ultra aesthetic zirconia go through to become teeth?

The preparation of super-beautiful zirconia all-ceramic teeth requires the combination of precise digital technology and clinical aesthetic design. The main process is as follows:

1. Aesthetic analysis and digital design

Oral examination and data collection

The tooth morphology and occlusal relationship data are obtained through intraoral scanning or silicone rubber impressions, and DSD (digital smile design) is combined to conduct

 personalized analysis of facial proportions and tooth morphology.

3D model design

CAD software is used to accurately design the morphology, edge fit and occlusal function of the zirconia crown to ensure the coordination between the restoration and the natural tooth.

2. Tooth preparation and temporary crown protection

Tooth grinding

Uniformly grind the tooth tissue (1.5-2.0mm on the incisal end and 1.0-1.5mm on the labial surface) to form a rounded edge to avoid stress concentration.

Temporary crown wearing

Before the formal restoration is made, wear a resin temporary crown to protect the prepared tooth to maintain occlusion and beauty.

3. Production and processing of zirconia crowns

CNC cutting

Import CAD data into the dental milling machine, cut high-purity zirconia material to form a base crown, the thickness is usually 0.5-0.6mm.

High temperature sintering

The cut zirconia crown is sintered at high temperature (about 1500℃) to increase the density and strength of the material.

Layered dyeing and glazing

The multi-layer dyeing technology is used to simulate the light transmittance and color gradient of natural teeth, and the glazing and polishing make the surface smooth and natural.

4. Trial wear and bonding fixation

Margin and occlusal adjustment

Check the edge fit, adjacent relationship and occlusal contact of the restoration, and make fine adjustments if necessary.

Adhesive fixation

Use resin cement or glass ionomer adhesive to permanently fix the zirconia crown to the tooth body and remove excess adhesive material.

5. Postoperative maintenance

Instruct patients to avoid chewing hard food, clean the crown edge regularly, and check the stability of the restoration every year.

Core aesthetic requirements

‌Color matching‌: Achieve the same hue, brightness and saturation as natural teeth through multi-layer dyeing technology‌; ‌Natural shape‌: The gradient design of the transparent layer 

at the incisal end and the enamel layer at the neck simulates the optical properties of natural teeth‌; ‌Margin concealment‌: The shoulder design of 0.5-1.0mm below the gum ensures 

that the restoration edge and the gum are naturally transitioned
