- The CRI Mouthpiece: A Better Approach to Jaw Support
According to the National Institute of Dental and Craniofacial Research, temporomandibular disorders (TMDs) affect more than 12 million people in the United States. For many, that means daily jaw pain, clicking, tension headaches, or interrupted sleep.
Night guards are often the first line of defense, but most over-the-counter options rely on bulky plastic molds that don’t always fit well or hold up over time.
Clench Relief Inc. (CRI) takes a different approach. Its patented mouthpiece uses medical-grade polyvinyl siloxane (PVS), known for its long history in healthcare settings. This isn’t a standard night guard—it’s a reimagined approach to TMD relief, grounded in clinical reliability and everyday wearability.
Why CRI Chose PVS: Material Basics and Benefits
PVS is a silicone-based material known for its stability, flexibility, and precision. It’s been a staple in dental impressions for years due to its ability to capture fine detail and hold its shape.
PVS doesn’t warp under pressure or lose its form over time, unlike acrylic or thermoplastic materials used in typical night guards. That consistency means a better fit, especially for devices worn overnight.
In the case of the Clench Relief® Pro Rx Mouthpiece, PVS material for TMD mouthpieces isn’t a new experiment—it’s a proven solution repurposed for ongoing jaw support.
A Proven Track Record: PVS in Medical and Dental Use
PVS isn’t new to the medical world. It’s widely used in oral applications like crown and bridge impressions, denture fabrication, and surgical guides—scenarios that require accuracy and stability.
PVS’s history in healthcare includes consistent use in sterile environments, where it’s valued for its dimensional accuracy, softness, and resistance to deterioration.
Beyond dentistry, proven PVS applications in medicine include use in ENT surgical tools and wound dressings, thanks to its biocompatibility and non-reactive nature.
That medical track record matters, especially for a TMD device worn both during the day and night. When the goal is reliable, long-term use, it helps to know the material has already earned the trust of medical professionals.
Built for Comfort and Daily Wear: Safety and Fit in Focus
PVS is hypoallergenic, non-toxic, and holds up under daily wear without breaking down or becoming brittle. That combination matters for something worn inside the mouth for hours every night.
PVS has enough give to avoid putting excess pressure on the jaw while maintaining its shape—it does not warp or shift. That consistency makes it a reliable TMD oral appliance material.
CRI’s decision to use PVS isn’t just for comfort—it’s to ensure your mouthpiece performs reliably day and night without creating new issues.
More Than Just a Guard: What Makes CRI’s Design Different
At CRI, we redesigned the mouthpiece from the ground up. The Clench Relief® Anterior Alignment Guide promotes proper jaw alignment, relieves pressure on the joint, and supports nasal breathing by allowing the tongue to rest comfortably in its natural position.
Unlike boil-and-bite guards or bulky acrylic pieces, the Clench Relief® Pro Rx Mouthpiece is compact and consistent.
It’s precision-formed using the same material trusted for capturing micrometer-level detail in clinical settings. That exact calibration supports targeted relief—reducing jaw strain, improving sleep quality, and cutting down on the back-and-forth common with traditional devices.
Trust by Design: FDA Clearance and Patent Backing
The Clench Relief® Pro Rx Mouthpiece is a prescription-only, FDA-cleared PVS oral appliance designed for people with diagnosed TMD. That clearance isn’t just a formality—it means the device meets established standards for safety, biocompatibility, and consistent performance.
The process includes a virtual dental evaluation, a confirmed diagnosis, and an at-home custom fit based on your bite.
Furthermore, the exclusive CRI patent for TMD mouthguards protects a design built around joint support, not just tooth protection. It includes features that promote jaw decompression and better tongue positioning—elements that aren’t part of most traditional guards.
Together, FDA clearance and patent protection show that this device isn't based on guesswork or general templates. It's tested, documented, and engineered specifically for long-term TMD support.
The CRI Mouthpiece: A Better Approach to Jaw Support
The Clench Relief® Pro Rx Mouthpiece stands out because it’s built to do more than protect teeth. By using PVS, CRI relies on a material with a long-standing record in medicine—one that offers stability, comfort, and safety.
The result is a dependable, noninvasive TMD solution. It’s not just a different kind of night guard—it’s a rethink of what support for TMD can look and feel like.
