Patented extraction technology

Pinctada Maxima (Goldlip pearl oyster)

After extensive research on the structure and properties of various types of mother-of-pearl, Doctors Serge and Georges Camprasse selected a particular type of oyster: Pinctada maxima.

This work led to the development of Bionacre®a revolutionary natural biomaterial extracted from mother-of-pearl. Whether in solid form (cut pieces), compact (moulded pieces), in powder form or as extracts, Bionacre® promotes regeneration and repair of hard tissue (bone, cartilage) and soft tissue (skin, muscles, mucus membranes), governed by the receivers sites.

A strong, sustainable patenting strategy has been developed to protect this innovative technology. Some 89 patents have been filed in 40 countries.

What is the patented biomaterial Bionacre®? ?

Bionacre® sternal plates

Bionacre® screws

Bionacre® refers to products developed by MEGA BIOPHARMA that involve mother-of-pearl, regardless of application.

The biomaterial Bionacre® exists in several forms:

1. Solid form

In solid form it is used to produce implants (plates, screws, dental implants, anchors, etc.) particularly for osteosynthesis (surgical fracture treatment techniques, skeletal problems).

2. Powder form

Depending on its granulometric specification, in powder form it can be used alone (as a bone substitute) or combined with other ingredients found in the formulations of products (dermocosmetic and dermatological creams, dietary supplements, injectable cements used in vertebroplasty, etc).

Depending on its granulometric specification, in powder form it can be combined with other components used in the manufacture of various products (bone substitutes, dermocosmetics, dermatological products, food supplements, etc.).

3. Compact form

Compressed mother-of-pearl powder is used to produce compact moulded implants (substitute bone pieces), with bioresorbable properties.

4. Liquid form

The liquid form is made from mother-of-pearl powder, and can be used as an ingredient in various dermocosmetic and dermatological preparations.

What does the extraction technology brought to bear on active mother-of-pearl molecules consist of?

It’s a revolutionary extraction process that makes it possible to reduce mother-of-pearl to micrometric scale and to extract the desired components from it according to the intended fields of application. Doctors Serge and Georges Camprasse have developed various modi operandi, which are all patented.
