With the development of 3D printing technology, the digital application of 3D printing on the oral cavity is constantly 

breaking through. These applications deeply optimize the medical process, reduce the pain of patient diagnosis and 

treatment, and achieve personalized customization of the oral cavity. So which models can be printed by 3D printing 

and applied to the digital oral diagnosis and treatment process?

1. Implant surgery guide
The digital 3D printing guide template for oral implant surgery is a personalized surgical aid that accurately transfers 

the  preoperative  virtual  design  implant  plan  to  the  patient's  mouth.  It  can help accurately control the position, 

direction,  angle  and  even  depth  of implant placement during surgery, assist the doctor in implant placement, and 

unify the final implant restoration with the ideal preoperative design plan, effectively reducing surgical risks, Shorten 

the treatment time.

2. Wax bracket
It is used to assist in the definition of teeth and maintain the accurate support of the denture installation.

3. Indirect bonding plate
Used to print trays for indirect bonding brackets in traditional orthodontic applications.

4. Wax crown
Used to assist the dentist in the preliminary estimation of the crown of the treatment design.

5. Repair the model
A restoration model printed with dental data obtained from a dental scanner or other 3D scanner.

6. Denture base
It is used to print the base of complete denture or partial removable denture.

7. Dental mold and temporary crown
Used to print temporary crowns or temporary bridges.

8. Artificial gums
Used for implant restoration model to obtain accurate model data.

9. Invisible correction model
Models used in the field of orthodontics.

      It can be seen from the above that 3D printing technology has various applications in the field of digital dentistry, 

which  can  basically  meet  the needs of doctors  in the diagnosis  and  treatment  process.  In fact, the application of 

digital  dentistry  has  already  begun  to  penetrate  imported  cavity  medicine.  Especially  in  foreign  countries,  the 

proportion of digital dentistry is higher than that in China.

      In general,  digital  dentistry  technology  based  on 3D printing has greatly improved the accuracy, aesthetics and 

efficiency  of  the  treatment  process.  At  the  same  time,  it  reduces  the  difficulty  and  threshold of dental implant 

operations and reduces the patient's pain.
