Dental resin 3D printing: the advantages of technology

The dental industry has made great strides in recent years through the use of additive manufacturing. There are a number of industry applications for this technology, including but not limited to the development of dental models, prostheses, implants and crowns. For these reasons, the increased democratization of dental 3D printing is generating good growth. According to the Markets and Markets study released this year, dental 3D printing is expected to generate $7.9 billion by 2027, representing annual growth of 20.2%. A statistic that makes sense if we look at the number of clinics and specialized centers that rely on the integration of 3D in their daily activities. This is particularly the case of the West Lake branch of the Dental Doctor clinic, located in Suzhou, China, which called on the expertise of the manufacturer RAYSHAPE to optimize its production processes and offer more precise solutions.

The main obstacle in dentistry, which has also been highlighted by the Dental Doctor clinic, is related to the manufacture and delivery of dental implants. They are a safe, effective and precise type of implantation in the patient, serving to replace missing teeth. Implants have strong mechanical properties and do not damage the rest of the natural teeth that make up the dentition. However, the problem lies in their high cost and in the long manufacturing and integration time in the patient. When patients have good oral health and only need one or two implants, the process is relatively simple. But when it comes to a major reconstruction, like half the teeth or a full denture, it takes a lot longer, both for implantation and for restoration.

The integration of additive manufacturing

After detecting this problem, the West Lake dental clinic began to evaluate different possibilities. The goal was clear: to shorten surgery and model manufacturing times, as well as to reduce the surgical trauma that accompanies it. As we know, resin 3D printing is one of the main processes used in the dental industry, followed by metal fabrication. Specifically, the solution to the problem was found in the Shape 1 Dental 3D printer, from the manufacturer RAYSHAPE, with which they were able to create surgical guides. Based on DLP technology, the machine is equipped with a UV lamp and has a printing volume of 144 × 81 × 200 mm. Combining high speed and throughput at an affordable price, this solution is ideal for integration into dental clinics and laboratories. It also includes ShapeWare 3D printing software in a dental version. Dr. LV Haoxin from the Dental Doctor clinic comments: “ The quality of the parts 3D printed by RAYSHAPE is very good and the precision meets our expectations. »

With the adoption of the digital dental implant system based on RAYSHAPE’s DLP technology, West Lake Clinic optimizes the entire process of surgical guides and dental implants tailored to the needs of each patient. Dr. LV Haoxin explains: “ The design of the guides is effective in reducing surgery time and decreasing postoperative reactions. When a patient needs to be treated to restore missing teeth, we can use this technology to design the ideal virtual implant before surgery. We then make a choice and judgment in the software about the axial direction, depth, site distribution, diameter and length, and even strength and shape of the implant. Finally, the precise surgical guide is used to construct the junction between this restoration and the implant, and precisely replace the design to achieve the desired result.. »

Advantages of resin 3D printing in the dental sector

The integration of RAYSHAPE’s DLP additive manufacturing systems has enabled the Dental Doctor clinic to leverage the benefits of technology in their business. For example, at the operative level, it is now possible for the clinic to simulate how to place the implant and determine the position, depth and orientation using the 3D printed guide. According to Dr. LV Haoxin, through additive manufacturing, digital implantation adopts minimally invasive technology in a short time, so that patients can perform the operation comfortably, relaxed and painlessly. More generally, we can highlight the significant time savings thanks to 3D printing when creating guides, even if they are complex or require more iterations. Increasing the quality of the parts is also an essential aspect to guarantee reliable, precise results without margin of error. Another important point is the optimization of costs, induced by the increase in customer acquisition. With faster processes, experts can focus more on customer service, and as they attract more customers, this translates into lower amortized cost of consumables and equipment.

Dental Doctor has thus become one of the first dental clinics in China to launch technological, intelligent and digital projects. The Shape 1 Dental 3D printer has been upgraded to the Shape 1+ Dental version, with new advanced features that allow better development of dental models. RAYSHAPE’s 3D printing solution provided patients with a distinctive and intelligent treatment experience, and its performance exceeded expectations.
