Ask about this product

The Dental Splint Soft resin from Harz Labs is a high-quality professional material designed for the 3D printing of comfortable and flexible dental splints, primarily intended to support and protect the teeth and jaw. Ideal for patients suffering from bruxism (teeth grinding) or temporomandibular joint (TMJ) disorders, this resin enables the production of splints that help alleviate discomfort and prevent further damage. The flexibility and softness of the material ensure a comfortable, custom fit that adapts well to the contours of the mouth, providing relief for long periods. The resin is translucent and the printed splints can be polished to offer an aesthetically pleasing end result for improved patient comfort.

The dental splint made from this resin not only offers comfort but also effectively reduces pressure on the teeth and jaw, promoting healing and minimizing discomfort associated with grinding or jaw misalignment. In cases when the tratment requires rigid stabilization of the joint, it is recommended to use the Dental Clear PRO resin from Harz Labs. Since the resin offers resistance to autoclave cycles and disinfectants, the splints printed with it are easy to clean and maintain, ensuring durability and long-lasting performance. For optimal results, it is recommended that the Dental Splint Soft resin splint be used under the supervision of a dental professional to ensure it fits correctly and provides the necessary therapeutic benefits.

Manufactured using biocompatible raw materials commonly found in photopolymer dental fillings, the resin adheres to ISO 10993 standards for biocompatibility. However, achieving biocompatibility in the final product depends on proper printing and thorough post-processing procedures, necessitating evaluation for each application.

The Dental Splint Soft resin is versatile and user-friendly, suitable even for small laboratory setups due to its low odor and absence of hazardous monomers. Its compatibility with a wide range of LCD/DLP 3D printers, including the Anycubic Photon Mono M3 Max and the Elegoo resin 3D printers from the Mars 4 and Saturn 3/4 series, makes it a practical solution for orthodontic professionals seeking reliable and efficient solutions for printing comfortable and flexible dental splints for patients with bruxism or TMJ disorder.

The recommended printing settings for various resin 3D printers can be consulted on the HARZ Labs support page. To see the settings for specific resins simply choose your 3D printer model and find the resin you want to use.

Once a print is finished, it has to be removed from the manufacturing platform with a special spatula for post-processing. It is crucial not to damage the surface of the platform during this operation.

Part post-processing

Then, the part should be immersed in IPA alcohol or other recommended solvent to remove the non-solidified resin. After that time, pressurized air should be applied to the part until it is completely dry.

To achieve the maximum properties that HARZ Labs resins can provide, it is necessary to post-cure the part in a curing chamber for the recommended time and at the recommended temperature. This process helps eliminate internal stresses.

Since the washing and post-curing parameters will largely depend on the equipment used, Harz Labs has preparad a post-processing table where the recommended parameters for each resin are given.

Safety measures

3D printing with resin requires certain personal protection measures to ensure the workflow is safe for all involved. It is recommended to use gloves and safety glasses, as well as use some kind of air filtering system if the printer is not equipped with one.

Resin storage

Avoid leaving resin in the vat for extended periods. Store the printer and resin bottle in a location away from direct sunlight, luminous or LED lights, and heat sources such as heaters to prevent curing.

To learn more about how to properly store 3D printing resins, read our blog post on the topic. There we discuss topics such as the effect of light, heat and moisture on resins, as well as resin recovery after printing, resin expiration date and how to preserve the biocompatibility of 3D printing resins.
