Our Story

Rhondium was founded in 2010 by Dr Simon McDonald with the aim to make the lives of everyday dentists dramatically easier and more productive.

Dr McDonald is no stranger to inventing break through products – he previously founded and built Triodent, a company that became well known for its multi award winning V3 Sectional Matrix System, used in class two composite restorations. Such was the company’s success that it was subsequently purchased by Dentsply Sirona.


Based in New Zealand, Rhondium consists of a highly skilled team of specialists, all brought together by their passion to create innovative and cutting-edge products for the dental industry. Using the latest high-tech methods such as 3D CAD design software, full five-axis, high-precision CNC milling machines and 3D printing, Rhondium can bring high quality products to market quickly. “It’s about doing things differently, and better. We’re using the very latest technology and applying very clever thinking. If we can dramatically transform how dentists work, by providing simple yet highly effective and innovative products that mean better results both for the patients and the dentist’s practice, then we are achieving our mission!”

Rhondium’s first product, the hybrid-ceramic One Visit Crown (OVC3) is set to revolutionize dentistry. It provides a durable, quality option for those patients that cannot afford an expensive lab crown or CEREC, and who would much prefer the procedure completed in one single appointment – saving them both valuable time and money.
