With the increasing prevalence of bruxism and temporomandibular disorders (TMD), the demand for durable, patient-specific occlusal appliances continues to grow. At the same time, digital dentistry workflows are reshaping how these appliances are produced—moving from manual fabrication toward fully digital design and additive manufacturing.
PowerResins Guard is specifically developed to meet these evolving needs. As a biocompatible, high-impact 3D printing resin, it enables dental professionals to produce precise, durable, and comfortable night guards and splints with improved efficiency and consistency.
Material Composition and Engineering
PowerResins Guard is a photopolymer resin formulated for LCD and DLP 3D printers operating at 405 nm, making it compatible with a wide range of dental printing systems.
Its composition is engineered to deliver a balance of strength, flexibility, and patient comfort, which is critical for occlusal appliances exposed to repetitive loading. The material is MMA-free and low-odor, improving handling conditions within dental laboratories while also enhancing patient safety.
From a regulatory standpoint, the resin is biocompatible (Class I, CE-certified) and manufactured under ISO 13485 quality standards, ensuring consistency and compliance with medical device requirements.
Mechanical Properties and Clinical Performance
The performance of a night guard resin is defined by its ability to withstand continuous occlusal forces without deformation or fracture. PowerResins Guard demonstrates a robust mechanical profile, including:
Flexural strength exceeding 100 MPa after proper post-curing
Flexural modulus above 2900 MPa, contributing to structural rigidity
Shore hardness (D) above 65, ensuring resistance to wear
These properties make it suitable for long-term intraoral use, particularly in patients with moderate to severe bruxism.
At the same time, the material maintains enough resilience to provide patient comfort and shock absorption, reducing stress on teeth and temporomandibular joints.
Precision and Surface Quality
In digital splint fabrication, accuracy directly impacts clinical success. PowerResins Guard is optimized for high-resolution printing, enabling:
Clean and well-defined margin lines
Accurate occlusal anatomy reproduction
Smooth surfaces suitable for polishing
This level of detail ensures a predictable fit and minimal chairside adjustments, improving both clinical efficiency and patient satisfaction.
Additionally, the resin prints in a clear or translucent finish, which is ideal for aesthetic appliances and allows clinicians to visually assess fit and seating during delivery.
Indications and Clinical Applications
PowerResins Guard is designed for a wide range of dental applications, particularly those requiring durability and precision. These include night guards, occlusal splints, and protective appliances used to manage parafunctional habits such as clenching and grinding.
Its ability to reduce stress on teeth and joints makes it a valuable tool in the management of bruxism and TMD-related conditions, contributing to both symptom relief and long-term oral health.
Advantages for Dental Labs and Clinics
PowerResins Guard offers clear advantages for both dental laboratories and clinicians.
For labs, it enables high-throughput production with consistent quality, while reducing variability between cases. For clinicians, it provides accurate, comfortable appliances that require minimal adjustment, improving patient experience and reducing chair time.
The material’s combination of strength, precision, and ease of use makes it a practical solution for scaling digital splint production.
