With the gradual maturity of technology and the continuous development of deep integration with the industry, dental 3D printing has been widely used in the field of oral medicine, which has greatly improved the accuracy and efficiency of oral medicine. The application of dental 3D printing in invisible correction and digital preparation of dentures may become the future development trend.

3D printed dental molds help the production of invisible aligners

In recent years, invisible orthodontic braces have gradually gained the favor of consumers and orthodontists due to their almost transparent appearance and portable and easy-to-wear characteristics. At the same time, 3D printing technology has also successfully gained a place in the manufacturing of invisible orthodontic braces.

The traditional production process of invisible orthodontic braces is data scanning, dental model restoration, CNC manufacturing molds, and thermoplastic braces. The main application of 3D printing is to replace CNC to make molds. Compared with traditional production methods, 3D printing dental molds have many advantages.

Reduce costs and save time

Each patient needs to wear multiple sets of orthotics during the correction cycle. The orthoses worn by each patient are customized, and each patient needs to replace multiple sets of orthotics during the correction period, and each orthosis is manufactured A corresponding customized dental model is needed behind the scenes.

If the mold is made by traditional CNC, CNC programming needs to be performed according to the patient's dental mold situation, and due to the particularity of the teeth, it is necessary to use a multi-axis machine tool for processing. The labor cost and equipment cost are very high, so the production cost of the braces will be very high.

For medical dental 3D printing, only the process of data collection, modeling, correction optimization, and dental 3D printer printing can be used to complete the production of dental molds. The cost of materials and machinery is reduced, and the production time is shortened.

Dentistry requires high precision, and any deviation in precision may bring a very painful experience to the patient. 3D printing supports digital modeling, which can make the size of the dental model suitable, and assist the doctor in the production of invisible aligners that are more suitable for the tooth, so that the patient can wear it well.

3D printed dentures break traditional production methods

The traditional denture production process includes: impression, plaster prototype, model, wax model making, embedding, casting, grinding and polishing. This process is inseparable from the manual skills of dental technicians in making wax molds and casting crowns. This production method has led to a high rate of rework of dentures, which not only reduces the work efficiency of dental technicians, but also reduces the suitability of patients to wear dentures. .

The subtlety of 3D printing is that dental patients no longer need to bite the dental mold. The dentist uses an oral scanner to scan the patient's teeth, jawbone and other oral structures to create a three-dimensional digital model of the patient's oral cavity. Then import the data into the 3D printer system to print out the denture base. After being refined and polished, it can be enamel, glaze, and then finished.
