Do you know how dental design designs your teeth?

For dentists, common dental washes, fillings, and wisdom teeth are not a problem. A true top dentist is how to design teeth on a millimeter-scale to give a new look to a rotten tooth. The progress of the dental design industry is largely driven by the entertainment industry. Actors who don’t cost anything to perfect their image have turned Los Angeles, where Hollywood is located, into the most developed dentistry region in the world. And the job of a top dentist is to constantly challenge on two fronts — optimizing appearance while reducing wear and tear.


A commonly used solution is called Digital Smile Design, or DSD for short, and Digital Smile Design in Chinese.

DSD was first developed and implemented by Brazilian dental specialist Christian Coachman. Achieve precise aesthetic restoration of teeth at the millimeter scale through oral model digitization, pre-tooth design, veneer manufacturing, and fine preparation.

The first step in digitization is accurate oral photography.

With 13 chair photos, 13 studio photos, and 2 videos, dentists can analyze patients’ teeth for convexity, texture, ribbon, occlusion relationships, and relationships between teeth, gums, and lips.

These findings will support digital design by dental design.


China Dental Lab LOYAL BEAUTY is designed like this:

The first thing that needs to be determined is the laugh line, the ideal position of the patient’s teeth when smiling. Based on the relationship between teeth and laughing lines, we can design each tooth that needs to be repaired.

The length of the middle incisor is determined first, and then the width of the middle incisor is determined according to the ratio. The ideal ratio is 75% to 85% of the length.

After determining the length and width of the middle incisors, a golden scale is usually used to determine the width of the other teeth. That is when the width of the side incisors is 1, the middle incisors with a width of 1.618, and the fangs with a width of 0.618 are considered the most standard ratio of teeth.

Of course, the dental design will also be adjusted according to the patient’s own characteristics. For example, Asians tend to have smaller middle incisors than Europeans.

The tooth data is then measured by an electronic vernier caliper to measure the value of the tooth that needs to be repaired.

These images and parameters will help dental technicians create dental veneers with precision.


Dental laboratory customer case


The first step in making veneers is to get a model of the customer’s teeth. The commonly used stamping material is silicone. Plaster is poured into the silicone mold to obtain the abutment model, cut the abutment model to make the impression mold, and then cast the refractory material on the stamp mold to obtain a working model with different materials.

The surface of the working model is covered with porcelain powder, and then the porcelain powder layer is sintered to form, and the porcelain tooth veneer can be obtained.

The key to veneering is thinness.

Today’s veneer thickness can be controlled at around 0.5mm. The thinner the veneer that adheres to the teeth, the less wear on the teeth. In addition, the color, gloss, and texture of the veneer also need to be fine-tuned, close to the real texture.

The low degree of standardization of porcelain veneers places high demands on the personal skills of technicians. The veneering needs of most dental hospitals can only be outsourced to dental outsourcing.

The edges of porcelain veneers are often only a few millimeters. In order for these 0.1-millimeters to be tightly bonded to the teeth, dentists need to complete extremely fine tooth preparation.

The Lycra oral microscope, which can be magnified 40 times, helps dentists achieve this millimeter-scale micro sculpture and complete the final step in aesthetic restoration.

The DSD scheme may not sound too difficult, but in practice, problems with the accuracy of the photographic position, image alignment, scale calibration, veneer making, tooth preparation, and bonding can lead to poor results.

If there is an error of several thousandths in every link, the last error maybe a few percent. If every link compromises zero millimeters, the final compromise may be several millimeters.

Dental design is all about precisely controlling what happens naturally.
