Our Story

Parent company 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 breakthrough 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 the UK, Rhondium Dental Laboratories UK Ltd consists of a highly skilled team of specialists, all brought together by their passion to create quality, innovative and cutting-edge products for the dental industry. Dr McDonald says

“It’s about doing things differently, and better. Our mission is to dramatically transform how dentists work, to create better results for both patients and dentists by making dental treatments more accessible and affordable. Through using the latest technology and applying very clever thinking, we can provide simple yet highly effective and innovative products.”

Rhondium Dental Laboratories Ltd UK is proud to be constantly innovating and perfecting our clinical procedures and solutions through consultation with our dentist customers.
