The natural look, thanks to cutting-edge technique 

PAGE 33 ARTEDENTAL 2

With the The BDT Techique®, the result of the prosthesis is much more real. Its structure facilitates the work because you do not have to create the tooth from scratch, but from a base that has already been mimicked in an extraordinary way with the mouth of the patient.

In 1958, while the Catalan Enric Bernat observed how some children played with the candies that they had in their mouths, he thought that putting a simple stick on them would prevent the little ones from getting their hands dirty. This is how the first pacifier or chupa chups came up in Spain. Today, the company with which Bernat started sells its products to 150 countries, invoices more than 500 million euros and employs more than 2,000 people.

The simplicity of this invention is so overwhelming that it is unlikely that anyone would have thought of it before, such as turning a keyboard into a touch screen or realising the usefulness of a submersible boat. The engineering behind it is complex, but the simplicity of the change is what makes them fascinating inventions.

In general, fixed dental prostheses are formed by an arc-shaped structure that is supported by implants. These implants, screwed to the bone, also hold the visible part of the prosthesis, the teeth, and distribute their weight by this structure. Until now this visible part was a single piece that functioned as a block adhered to the structure. The biggest handicap of this block is that if a single tooth was broken, the whole block had to be extracted and recreated. For a patient this is the most important part, and therefore the prosthetists work on it in real detail. They mill, they carve, they paint. Each shape, each flute, each colour is essential for the piece to mimic a real denture. And not any denture, but the one that best fits the aesthetics and physiology of each patient. It is an artisan work of incredible precision.

Six years ago, the British Lee Mullins and Phil Reddington achieved a fundamental improvement for this specialty. Why not create this structure with a material that would allow more detail and copy every millimetere the way in which our mouth was? That is, if we had lost our teeth, this structure would have the shape of our gums; or if they had fractured, it would have the shape of the stumps. It would no longer be necessary to create a piece that will be cemented to the structure, but the teeth that we need individually and uniquely. Another simple idea that could mean a paradigm shift in an entire profession.

This is what is known as BDT® Technique (Burn-out Denture Tooth). A shallow search on the Internet suggests that it is a “secret” technique. The technicians keep it as if it were a valuable treasure. In Tenerife, at the Artedental clinic, the ambassador of this technique in Spain, Fernando Griffón, works as a prosthetic teacher. For him, the BDT® Technique has “changed his life”.

“Before, a veneer that was only frontal was cemented. Besides requiring more time, the result was much less aesthetic, “explains Master Griffon. “With BDT®, the result is much more real. This structure makes it easier for us to work because you no longer have to create the tooth from scratch, but from a base that has already been mimicked in an extraordinary way with the patient’s mouth. In addition, the teeth are not made of an acrylic material, but ceramic, so the precision that is achieved in the forms is infinitely better.

The structure however is manufactured with Pekk or BioHpp, a high-performance polymer that is now used in the prosthetic industry at any level: in the hip or spine; and even in the manufacture of aircraft and in the automobile industry. Its characteristics make it much more aesthetic, solid, resistant and durable; hence, it is preferred to other materials in the manufacture of prostheses.

The master of Artedental, a tireless researcher of new procedures, had the good fortune to meet his creators in separate dental congresses in Cologne and Birmingham. The relationship between them and the professional skill and background of Griffón led to today being the largest representative of this inno-vative technique through-out the country, a method that in addition to the United King-dom and Spain, is already practised in Argentina, the United States, France or the Libano; and that it serves for all types of prostheses: unitary, bridges or complete.
