The traditional workflow in dentistry implies the cooperation of two parties involved in the process — dental clinics on the one side and prosthesis laboratories on the other, the interaction between the two requiring quite a lot of time and logistics. Since every patient has a unique dentition, dental labs mostly use manual production methods which are usually slow and assume the work of highly skilled dental technicians, still leaving a lot of room for probable imperfections in the final result. The use of 3D printing provides wide opportunities for low-cost mass customization, saving time and ensuring extremely high precision of printed models. A wide range of dedicated biocompatible materials with various properties allows for the creation of orthodontic models, crowns and bridges, surgical guides, aligners, retainers, splints, dentures, and other dental products that perfectly match the patient’s anatomy.

Applications of 3D printing in dental industry

Aligners

Aligner production is an example of using 3D printing as a bridge to traditional manufacturing methods. First the dentist takes the impression of the patient’s mouth by means of intraoral scanning with further converting the scanned data to a CAD model, which is then edited to specify the stages of desired teeth shifting. When this is done, the model for each stage is printed, usually employing SLA technology. After that each printed model is placed into a thermoforming machine where a clear aligner is wrapped around it creating the patient-specific set of aligners.

Surgical guides

Surgical guides are used in medicine, dentistry in particular, to assist the surgical procedures. In dentistry surgical guides are of great help in implantation as they ensure the precise placing and fitting of the implant. The guides are placed directly over the patient's teeth and then removed during or after the surgery when no longer needed. Surgical guides not only increase the accuracy of the procedure, but also make it faster and less invasive thus shortening the recovery time. Different manufacturers offer special surgical guide resins to ensure the best printing results. 

Crowns

3D printed dental crowns are becoming more widespread with the development of new biocompatible materials. First additive manufacturing was used only as a bridge to investment casting process helping create accurate casting patterns. Now there are a variety of materials, from special permanent crown resins, like Formlabs Digital Dentures Resin, to various metal alloys, that allow printing high-quality permanent crowns taking all the advantages 3D printing provides.

Dental models

Dental full arch or crown and bridge models with removable dies help dentists while planning denture restoration. Dental models are printed based on the digital impression of the patient's mouth so they are indispensable when it comes to checking fixed prosthetics that will be later used in a patient's treatment. Special materials, like Formlabs Dental Model Resin allow for precise models with matte smooth surface and a high level of detail.

How are dental models 3D printed?

The process of 3D printing in dentistry always starts with the dentist taking a digital impression of a patient’s mouth with an intraoral or desktop scanner. The obtained data is converted to a CAD model which can be saved and then used as a basis for creating dental print models when needed. The digital model is sliced using appropriate software and sent to the printer. Once printed, dental parts usually require some post-processing steps depending on the technology and type of material used.

Does dental 3D printing require special training?

The process of dental 3D printing is mainly automated and generally requires less special skills than dental technician’s work. Still, certain training is required, especially for those not familiar with additive manufacturing technologies in general. 3D printing equipment and material manufacturers usually offer training programs and support for their customers. In fact, digital dentistry allows for chair-side creation of some patient-specific dental products, while more complex parts have to be printed in dental labs by skilled professionals.

How to get digital models for a 3D printer

As mentioned, a dental 3D scanner (for example, Shining 3D Aoralscan 3) is used to capture the patient’s dental anatomy and take a digital impression of their teeth and gums. This digital impression is converted to a CAD file that is edited to create a digital model of the specific dental product, for example, a crown, depending on the particular case and treatment plan.

How to print dental custom trays

In traditional dentistry trays are used to get a patient's teeth impression, usually with plaster. The implementation of 3D technologies offers much more convenient and precise digital impressions made with an intraoral scanner. Yet impression trays are still widely used in dentistry either by those who prefer conventional methods, or in cases when digital scanning is impossible for some reason. The use of standard trays has always been a compromise as they can not guarantee the necessary precision which a custom-made 3D printed tray provides. The process of printing is the same as with other dental products, and the final result ensures getting highly precise dental products in a shorter time. Different manufacturers offer special resins for impression trays production.

Criteria for top dental 3D printers

Precision

Print precision is one of the key points to be considered when choosing a dental 3D printer. If you are going to print not only educational models just to show your patients the treatment process in detail (in that case almost any desktop 3D printer will do), but working dental products, then you should look for a high resolution device, as even subtle discrepancy can lead to a completely unsatisfying result.

Speed

Speed is always of great importance when it comes to business. High print speeds are helpful, whether we speak about dental labs or in case of chair-side printing in dental clinics, where rapid printing helps minimize the number of a patient’s appointments with the dentist.

Biocompatible materials support

It’s by far the main feature the printer should possess to be called dental. All dental products that come in contact with the patient’s mouth or skin should be certified biocompatible in your area, so it’s highly recommended to check the material compatibility list while choosing a dental 3D printer.

Dental printing materials

For today, the most popular technology for dental 3D printing is vat photopolymerization, which includes SLA, DLP and LCD-based processes, all of them using liquid resins that are cured by a light source. Hence the choice of special dental resins in the market is really vast. All dental resins are biocompatible and can be used for printing temporary or permanent dental parts with required properties.

Metal 3D printers are becoming more and more widespread in dentistry as they work with different metal and metal alloy powders, for example, titanium or cobalt chromium, traditionally used for fabrication of crowns, dentures, and stents. DMLS printers are capable of producing durable extremely precise models in a short time.

Another popular technology for dental 3D printing is material jetting that prints with liquid materials — plastics or polymers — which are cured by UV light. The technology boasts the exceptional accuracy of the printed models, but the printers utilizing this technology are usually bulky and expensive.

As for FDM printing, despite its popularity in a lot of other industries, it has not been widely used in dentistry, as FDM machines usually demonstrate lower accuracy than the other technologies mentioned above. However, new FDM 3D printer models show much higher resolution, accuracy, and dimensional stability, compared to their predecessors, and now dental industry can take advantage of all the benefits of FDM technology.

This is the Best Dental 3D Printer for Dentist

Dental 3D printers or 3D printing is a fast-growing technology in various business areas, most particularly in the field of a laboratory. A Dental 3D printer features a laser or light, blends or fuses a powder, and polymerizes a fluid with the technologically guided precision needed to generate small objects with complicated details.

A Dental 3D printer can generate models, parts as well as full restorations regardless of materials. Adding a 3D printer to your laboratory or practice can enhance effectiveness. There are many types of dental printers intended for the particular production level, laboratory sizes, and specific tasks. When choosing the most reliable 3D printing, check the program the printer is well-suited, the materials are capable of printing, and the support and training presented by the company.

3D Dental Printer in dentistry is exploding, and the market is full of different types of printers. We will help you get the right one by reviewing some of the best models on the market. They are all made from high-quality materials and have excellent capacity. Read on!

Our dental formula is one of the key aspects that symbolize beauty. If you have problems with them, you can fix them quickly, thanks to the advancement in technology. The 3d dental printer has significantly improved the experience of patients in dentistry.

They provide affordable fabrications by utilizing the printed dental appliance. It is a technology that is finding its way across other industries all over the world. Though this is the case, it is undeniable that the dental printer is a unique innovation in digital dental practice.

Every professional enjoys having a versatile device that can make their work more enjoyable. A 3d dental printer is one of those devices that bring joy to dentists. It can print functional dental appliances like monolithic dentures, nightguards, and clear aligners. It can also help dentists produce certified final products and not only models or prototypes. The printed items are therefore ready to use without requiring any polish.

As a lab technician looking for a 3d printer, the cost is not as important as the functionality. It would help if you searched for one that can efficiently utilize functional resins to develop diverse applications, including dentures base and indirect bonding trays. Such a printer can boost the dental workflow and expand the capabilities of digital dental practice.

Though many printers can fabricate surgical guides, not all can print final appliances as 3d dental printers do. These are different since they can use biocompatible resins to give you an impressive final appliance.

As you make a 3d printer comparison, you should understand the printer’s fabrication ecosystem to avoid being limited to only a few applications. You need a broad range of applications that you can use in digital dental practice. Your printer should also be in a support ecosystem designed for dentistry.

We can categorize 3D printing into two. If you have a big dental lab where you create many appliances every day, you should choose the industrial 3d printer. This type includes machines that have a high capacity to work. They are large and are suitable for high-volume laboratories.

An oral surgeon or a prosthodontist working at a small clinic needs a desktop 3d printer. The 3d dental printer comes at a lower price than the industrial type and has a manageable size. A Desktop dental printer is versatile but has a smaller platform. Regardless of the kind of dental printer you choose, you should ensure that it has certified resin capabilities to boost your dental workflow. It can help you print dentures, bridges, or even crowns so that you can offer your patients expanded treatment options.

A lot of dental labs rely on 3d dental printers to access customized items. Every patient has a unique morphology which makes dentists use matching implants or prostheses to match this. 3d printers make it easy for you to get an accurate model for a patients’ dentition for a successful dental restoration.

Many patients with dental problems need quick solutions, and 3d printing delivers that and much more. It is time-saving and also cost-effective. By modifying a 3d design, you can make a 3d printed device to fit well in a patient’s mouth to ease discomfort. It prevents you from redoing the entire process, like in the case of injection molding.

The market is full of dental printers and business models that try to make a difference in digital dental practice. As you make the dental 3d printer comparison, you should go for one that offers a wide variety of dental materials and uses advanced technology to increase productivity. It should also be able to help you create different dental appliances at a low cost.

Unlike the traditional plastic model, a 3D Printer is a more durable, precise, and stable alternative. The edges and lines on 3D printers are sharp, so there is no need for a lab technician to wear them down. 3D Printed model, on the other hand, has a complex formation with a superior level of detail.

These days, 3D printed implant model is the most after the product as it comes with high-quality detachable dies and an exceptionally flexible and detachable gingival mask. This is made of material comparable to a human gum, which is soft, thus allow lab technicians to do the job almost as if it was prepared straight in the mouth of the patient.

The most important benefit provided by 3D dental printing is that it saves you lots of time. After intra-oral scanning, the digital copy of the result is sent straight to a dental laboratory. The digital copy is received in just a matter of minutes as sending is effected electronically. The lab tech can start working right away. 3D dental printing also provides organized and clean working areas for the tech without dealing with plaster or inhaling grinding dust.
