Facts about dental 3D printers:

The digital dentistry industry is experiencing a revolution due to 3D printing. With chairside fabrication of dental models and surgical guides, procedures that used to take weeks can now be completed in hours, giving local dentists full control over patient-specific products. Fewer appointments are required, turnaround times are shorter, and costs are significantly reduced with the ability to produce applications from digital files, such as night guards, temporary crowns, and dentures . This leads to an overall improvement in patient care.
Let’s take a look at the growing range of solutions that could bring your business or dental lab into the digital age.

Know your needs

Dental models for patient education and dental parts for patient use are very different from each other, as any dentist or dental laboratory expert can attest.
There is no need for a specialized dental printer if your goal is to print relatively accurate models of a patient’s mouth from an oral 3D scan or impression to, for example, explain a process to a patient. In fact, there are many more dental 3D printers available for making models than there are for printing parts of dental supplies that will come into contact with patients.
Stunning dental models can be printed with almost any resin printer, including most of the best filament printers.
However, you will need to use biocompatible materials certified by regulatory authorities in your region, such as FDA in the US, CE in the EU, KFDA in South Korea, etc., and approved software and 3D printers if you are looking to print biocompatible dental parts, i.e. anything that will come into contact with a patient’s mouth or skin, e.g. clear aligners, veneers, temporary or permanent replacement teeth or dentures. This is what this article focuses on.

Biocompatible Dental 3D prints

Working with a 3D printer manufacturer that focuses on the dental sector (either entirely or as a large part of its business) makes sense because there are several regulations related to medical devices. These companies provide real-world knowledge, support, a network of dental-specific products and services, and a continuous supply of essential consumables.
Since integrating 3D printing into your dental practice or lab requires learning new methods, tools, materials, and procedures, it follows that you will not fully benefit from your printer purchase without adequate training and support.

Embrace the dental impression ecosystem

Digital dentistry is, of course, more than just 3D printing. Many manufacturers offer a suite of software, oral scanners, 3D printers, post-processing units, etc., in a packaged approach.
Many 3D printer manufacturers offer dental solutions with service plans including custom onboarding, proactive registrations, phone and email support, and resource libraries including manuals, tutorials, and videos . A number of 3D printer manufacturers, including SprintRay and Kulzer, focus solely on digital dentistry. They offer an in-depth strategy and ensure seamless integration of dental impression software, printers, accessories, materials and support.

How are dental parts 3D printed?

Here is a brief overview of the process of creating a personalized in-office dental night shift for each patient to show how the elements of digital dentistry interact.
Starting with a digital scan of the patient’s mouth with a handheld intraoral scanner, an external scanner or the scan of a cast or traditional dental cast model.
Your digital images are then uploaded to CAD software specifically designed for the dental industry, such as Exocad, or the software that accompanies your 3D printer. Select the software based on your skill level and the skill level of your staff. Many dental CAD programs are compatible with most major 3D printer manufacturers.
The next step is to transfer your design files to slicer software, which either comes with your printer or is compatible with it if your dental software does not do this automatically (most do). The slicer converts your digital model into print-ready 3D printing instructions.
Your night guard should be cleaned to remove any residue, supports removed, and it should be light cured to harden after being fully printed in an approved biocompatible resin. It usually needs to be polished as a final step before the patient can try it on. The entire procedure may take several hours, depending on your printer.

Criteria for The best dental 3D printers

What you plan to print, how much you plan to print daily or weekly, how quickly you need your parts, your budget, and how automated or user-friendly you want the process to be. either will influence the printer you choose. biocompatible dental parts. Have you just started, expanded or modernized your operations?
In addition, you should consider the degree of service and support from the manufacturer and the dental software compatible with the printers. Requesting a print sample will allow you to determine if the print meets your requirements for detail, surface finish and strength. Most manufacturers will send you one.

Dental professionals responding to a survey by printer manufacturer Carbon ranked accuracy, reliability, maintainability, return on investment, total cost of ownership, quality of materials and lowest price as top factors to consider when choosing a brand of 3D printer for their lab.
Taking all this into consideration, a dental 3D printer that stands out is the J720 dental 3D printer.
