Liquidmetal featured in Isolite 3

The first dental isolation system to include both white and a true, cure-safe amber light for intra-oral illumination.

 

The Isolite 3

Zyris, Inc., the industry leader in dental isolation technology, has announced the new Isolite 3 dental isolation system.

The new Isolite 3 allows dentists to quickly and easily implement a standard protocol for consistent outcomes in procedures that benefit from and require moisture control and isolation.

“Our company was born out of the frustration of one dentist, and we are delighted to introduce the next generation of our flagship product,” said Sandi Hirsch, CEO and Co-Founder of Zyris. “The Isolite 3 incorporates feedback from hundreds of enthusiastic clinicians with the innovative talent of our design team. We are thrilled to help drive stronger oral health through a better patient experience!”

Quality – Made using Liquidmetal technology in the USA, making the Isolite 3 lighter, yet stronger than previous versions.

Productivity – Continuous hands-free suction evacuates water, saliva and debris for unsurpassed moisture control.

Risk management – The Isolite 3 shields soft tissue from sharps.

Illumination – The Isolite 3 provides unsurpassed visibility with three levels of bright, long-lasting LED illumination where dental clinicians need it the most.

Predictability – The Isolite 3 removes many of the negative variables that can impact treatment including moisture, contamination, soft tissue interference, low visibility and restricted access.

Ease – Unlike rubber dam placement, the Isolite 3 can be placed, removed and places again in seconds. Try doing that with traditional isolation methods.

 

The Amorphous Alloy Impact

Zyris is on the cutting edge of dental isolation. Similarly, amorphous alloys are on the cutting edge of metal manufacturing, minimizing trade-offs that are often made with traditional processes and metals.

The Isolite 3’s housing is a critical component within the product’s assembly. It requires a cosmetic surface with corrosion resistance, strength, precision, and light-weight.

When manufacturing any high-performance medical application, precision and part-to-part consistency are critical. That is why many Liquidmetal customers initially involved CNC machining in the manufacturing of their component. Liquidmetal’s amorphous molding process yields precision parts that match CNC machining with ±0.08 tolerance control (% of feature size). Engineers can usually expect ±0.3-0.5 tolerance control with traditional molding and casting processes. The Zyris’ engineering team leveraged this process capability to overcome design limitations posed by the product control base’s titanium housing.

Maintaining corrosion resistance to hospital-grade disinfectants is critical for any reusable medical device. Amorphous alloy LM105 instills confidence in the Zyris team with corrosion resistance that matches top crystalline alloys, including stainless steel, which is common in a hospital environment. The housing’s cosmetics are critical considering its visibility to the patient and dentist. LM105’s as-molded surface features a flawless surface finish, achieved following a single molding step, media blasting and PVD coating for a specific surface color.

The Zyris team created their next generation product with an advanced design requiring elastic properties that push the limits of titanium and stainless steel. To avoid trading away one of their critical design features, amorphous metal molding yields elasticity multiples greater than crystalline alloys in combination with twice the strength of titanium.

Identifying metals lighter than LM105 is easy, but the inverse relationship between strength and weight is inevitable. Almost every material will produce the same result; additional strength leads to extra weight. Amorphous alloys break this expectation, providing a strength-to-weight ratio value over 15% greater than Ti-6Al-4V, a grade typically used in medical devices.

Ultimately, when it comes to selecting a material and process, the Zyris team determined what design traits and material properties were critical to their application. Liquidmetal’s AMM process resulted in zero trade-offs on their behalf in an economical package.

 

Working toward a win-win

In a robust market of manufacturing options like metal injection molding (MIM) and CNC machining, our team understands the obstacles a new technology will face. Zyris Sr. Engineer Brian Halleck found immediate confidence working with the Liquidmetal team, “Liquidmetal did more than share knowledge; they provided in-depth evaluations of components and dimensional reporting on elements that were critical to product development.”

Amorphous metal molding is not an iteration of an existing process, nor is it a new take on the same materials. AMM puts a new tool in the belt of engineers and product designers in markets that in many cases have used the same manufacturing technologies for decades. With this in mind, transparency and willingness to go above and beyond is critical for Liquidmetal to help new customers succeed.

Brian discovered a surprising depth of knowledge at Liquidmetal, but most importantly, a willingness to assist in any situation. “They were very positive, professional, and attentive every step of the way.”
