Application of 3D Printing Technology in the Field of Dentistry

With the continuous development of information technology, mankind has entered the era of rapid digital development, and digital technology has been widely used in various fields.

3D technology and dentistry have a close correlation, the development of three-dimensional imaging technology to promote the development of 3D and other technologies, so that 3D technology is widely used in the treatment of oral diseases.

1. 3D printing dental model

Plaster models are often used in orthodontic treatment, and plaster is used to take the mould and make the corresponding corresponding materials according to the situation. However, the production of the air humidity requirements are high, if the preservation area humidity is large, it is easy to be deformed by moisture. In addition, the material has a low density and is easily damaged during application.

The resin model obtained by 3D printing technology based on intraoral digital scanning model and light-curing moulding has been greatly improved in terms of precision, strength and easy preservation, etc. 3D printing technology applied to orthodontic treatment can improve the degree of alignment of the teeth, and the orthodontic orthopedic model made by this technology can be precisely fitted with periodontal tissues of the patient to avoid periodontal tissue damage caused by wearing it in the orthopedic orthopedic model, which is highly clinically applicable and safe. Safety.

2. Invisible orthodontic model

In the late 1990s, American Align Company successfully produced commercial invisible aligners, and its mature orthodontic system is recognised by more and more orthodontists in the world, and is also favoured by adult patients for its beautiful and comfortable advantages. The rapid development of trayless invisible aligners is inseparable from the development of 3D printing technology. For invisible orthodontic technology, 3D printing can output high-precision tooth row models to simulate the movement of teeth in a more detailed way, thus making the movement of teeth more accurate. Compared with fixed aligners, the personalised advantage and precision of invisible aligners are more obvious. Therefore, 3D printing promotes the development of invisible orthodontic technology.

3. Dental mould and temporary crown

3D printer prints crowns with high surface precision and good surface reduction, and it takes only 3 hours to print a version of dental mould. 3D printer is equipped with intraoral scanner, which realizes a set of process from scanning, software and digital processing, replacing a large amount of manual labour and improving work efficiency.

4. Wax crowns and wax brackets

Wax crown is used to assist the dentist to estimate the initial treatment design of the crown; wax bracket is used to assist the fixed denture, to maintain the denture installation precision support body.

5. Artificial gums, indirect bonding discs

Artificial gums are mainly used for implant restoration models to get accurate model data; indirect bonding tray is used in traditional orthodontic applications, printing indirect bonding tray for brackets.
