Photopolymerization 3D Printing Applications: Surgical Guide Resin Empowering Digital Dental Care

From August 20-23, 2024, the 25th Radiation Curing Annual Conference was successfully held in Yichang. Shenzhen Esun Industrial Co., Ltd. (brand “eSUN”) participated in the conference, where the company’s deputy general manager, Mr. Chen Rui, presented a keynote report titled “New Applications of Photopolymerization Technology in 3D Printing.”

As a new productive force, 3D printing technology is widely applicable in industries such as manufacturing, dental care, electronics, and automotive. Among them, dental applications are one of the typical use cases for photopolymerization 3D printing technology. With the optimization and improvement of materials, equipment, and related technologies, the global dental 3D printing market is experiencing rapid growth.

eSUN is primarily focused on the R&D and application of 3D printing materials, offering a wide range of high-performance 3D printing filaments and photopolymer resins. Among them, the dental photopolymer resin series, such as SG100 Surgical Guide Resin, OM100 Orthodontic Model Resin, DM100 Restorative Model Resin, DC100 Dental Casting Resin, WO100 Water-Washable Orthodontic Resin, CT100 Customized Tray Resin, GM100 Gingiva Simulation Resin, and TC100 Temporary Crown and Bridge Resin, have been applied in dental clinics and related institutions.

Next, we will use the Surgical Guide Resin as an example to detail its performance characteristics and practical applications in clinical treatment.

The Surgical Guide Resin developed by eSUN is a biocompatible dental resin that can be sterilized under high pressure. This material has high mechanical strength, low water absorption, and is easy to polish.

1. Biocompatibility

As a medical device material, biocompatibility is one of the most critical requirements. eSUN’s Surgical Guide Resin has received FDA and CE certifications, ensuring good biocompatibility and product safety, without causing adverse reactions in practical applications.

2. High Mechanical Strength

eSUN has utilized unique photopolymerization post-processing techniques to create a highly cross-linked molecular structure during the curing process of the printed resin, significantly enhancing the material’s flexural strength and impact resistance. Additionally, this ensures dimensional stability and prevents deformation during high-temperature steam sterilization. These high-strength characteristics make this guide resin ideal for applications requiring high strength, such as surgical guides.

3. Low Water Absorption

eSUN’s Surgical Guide Resin has low water absorption, a crucial characteristic for medical devices that need to be placed in the oral cavity for extended periods. Low water absorption helps ensure that the related models maintain dimensional stability in the moist oral environment without compromising performance.

4. Easy to Polish

Oral devices require a smooth surface to reduce bacterial adhesion and food residue. eSUN’s Surgical Guide Resin has a smooth surface that is easy to polish, achieving higher precision and aesthetics, meeting clinical application needs.

The customization advantages of 3D printing technology allow users to quickly obtain “tailor-made” high-precision devices, ensuring treatment effectiveness and recovery speed. Surgical Guide Resin plays an important role in orthodontics and implantology, providing doctors and patients with safer, more effective treatment tools through high-precision 3D printing technology.

In summary, 3D printing technology has broad and comprehensive application scenarios in dentistry, covering the entire process from model making to the final restoration. In the future, the application of 3D printing in the dental field will become even more widespread and in-depth. In this process, material development is also crucial, with performance optimization and the development of innovative categories bringing more possibilities to dental care.

eSUN looks forward to cooperating with upstream and downstream enterprises in the dental industry to jointly promote the industry’s transformation towards digitalization and intelligence, providing patients with a better treatment experience.
