“Learn from nature: that is where our future lies.” (Leonardo da Vinci)

The Doctors Camprasse are the inventors of our patented biomaterial a sustainable innovation inspired by nature. 
Having been shell collectors since their early childhood, in 1982 they had an idea that they now describe as self-evident, even though the premise seemed crazy at first: what if the nacre of a specific species of shellfish, which is ivory-coloured and harder than a bone, could be a substitute for it? They then embarked on research work which led them to make major discoveries, and which was the subject of a host of scientific publications as far back as the late 1980s.

When passionate biomaterials enthusiast Joel Drai crossed paths with the Camprasse brothers in 2009, he was fascinated by their ingenuity and perseverance, and by their wealth of research work. He aligned himself with their vision: believing in the potential of nacre to treat beings.
Joel Drai then decided to set up MEGA BIOPHARMA, involving the dental surgeon twins in the venture. Ever since, the founding triumvirate has been determined to draw on these discoveries to design and develop medical devices and treatments to enhance the medicine of the future and yield benefits for the wider population.

The genesis of MEGA BIOPHARMA


Start of research works by the Doctors Camprasse on nacre.


Invention of a nacre based biomaterial
Proof of its safety and biocompatibility in respect of human subjects.


Design of dental implant prototypes based on nacre
Filing of the first patents – First clinical cases in humans


First publications and conferences: emergence of international interest in nacre



Joel Drai set up MEGA INDUSTRIE, a group specialising in the distribution of dental and pharmaceutical products aimed at healthcare professionals


Joel Drai set up MEGA DENTAL, specialising in the distribution of dental and orthodontic supplies, quickly becoming a market leader


With a view to promoting innovation, MEGA INDUSTRIE developed MY PEARL , a manufacturer of a revolutionary dental alignment system, and FEEDJI, a platform to manage exchanges between dental surgeons and mutual insurance companies
