3D printing temporary dental crowns is a method of digital production of temporary dental crowns, which has great advantages over traditional temporary dental crowns. If the clinic wants to develop digitally, I think it is necessary to introduce relevant 3D printing equipment.
What is a temporary crown?
Temporary crown is an important part of fixed restoration. Its main function is to protect dental pulp from damage before formal tooth wearing, ensure correct gum position and prevent tooth displacement due to missing teeth. Therefore, the temporary crown requires good surface smoothness and strength, and the crown has high accuracy and good retention effect.
What are the methods of making temporary crowns?
At present, the manufacturing methods of temporary crowns can be roughly divided into two kinds: one is traditional manual manufacturing, which needs to pour quick setting gypsum model to make temporary crowns on the model; One is to directly produce temporary crowns by 3D printing.
(1) Traditional handmade
The traditional manual production is mainly to make temporary crowns on the gypsum model. It is necessary to extract the local impression of the position of the temporary crowns before tooth preparation, collect the tooth data, and then pour the gypsum model through the impression. At the same time, the self setting dental resin is mixed. When the self setting dental resin is still in the paste stage, the resin is directly stacked on the gypsum model. After solidification, it is removed for shape trimming, grinding and polishing. In the process, it may be necessary to try it on in the patient's mouth for many times, so that the final temporary crown is more suitable for the patient.
(2) 3D printing production
Through 3D printing, the process will be more convenient than making on the model. Take the solution of Hager technology, a 3D printing solution provider, as an example:
In the data acquisition stage, the patient's oral data are obtained through oral scan + CBCT or model warehouse scan; The collected data will be directly transmitted to PioNext design center, and the professional dental designer of PioNext design center will arrange and design the temporary crown; After the design is completed, the data will be synchronously transmitted to the desktop dental 3D printer. Doctors can complete the printing of temporary crowns with one click with simple operation on site.
What are the advantages of 3D printing temporary crowns?
First, the materials used for 3D printing are mostly photosensitive resin, and the molding smoothness must be better than the traditional manual manufacturing that needs to be trimmed, polished and polished.
Second, the temporary crown shape is designed by computer calculation. The more accurate the collected data is, the more accurate the 3D printing of the temporary crown will be.
Third, it is produced by 3D printing, which simplifies the steps and is more efficient. Compared with traditional handmade temporary crowns and 3D printing temporary crowns, the advantages of 3D printing mainly lie in better surface smoothness, better crown strength and molding accuracy, and can provide higher diagnosis and treatment efficiency for clinics. Therefore, from all aspects, in fact, the introduction of 3D printing equipment in the clinic is a very good choice.
