Preteeth AI

The better understanding,
the higher case acceptance rate


Our mission is to increase dentints' case acceptance

90% of treatment plans are rejected by patients. Even the most gifted dentist, with best equipment, is completely worthless until the patient says "yes" to their treatment.

Esthetic composite resin can mimic the complicate appearance of natural tooth with various color and translucency. With AIDirect's algorithm, a perfect match of materials will be recommended.

Minimal invasive

Using the composite resin is a conservative way to rehabilitate your charming smile. Materials are added on the surface of your teeth with adhesion technology instead of cutting of the tooth surface.


It only takes one afternoon to accomplish the treatment with the aid of AIDirect's AI Algorithm and Customized Filling Guide. It's a both time-saving and precise way to give you a perfect smile.
