Innovation Seal 2010

BTI has been awarded with the second prize of “Innovation Seal 2010” awards at “best R+D infrastructure” category. This is the recognition to the several developments done at business network. The “Innovation Seal 2010” Awards are organised by the Association of Science and Technology Parks of Spain (APTE), with the support of the Spanish Ministry of Science and Innovation.

The World Anti Doping Agency (WADA) has withdrawn from the 2011 list of prohibited substances and methods the intramuscular treatment which includes PRGF

The World Anti-Doping Agency (WADA) has withdrawn from the 2011 list of prohibited substances and methods the intramuscular treatment known as PRP, which includes PRGF, the treatment with autologous growth factors (from the patient himself), developed by the Spanish doctors Eduardo Anitua and Mikel Sánchez. This procedure, which greatly accelerates tissue regeneration times to allow an earlier return to sports, had been included by WADA in the 2010 list of prohibited substances and methods for use in muscular injuries, although it was allowed both for tendon and ligament injuries.

Thanks to the mediation of the Spanish Olympic Committee (COE), the innovative treatment of the Spanish doctors Eduardo Anitua and Mikel Sánchez has been allowed again by the World Anti-Doping Agency. Over the period of one year, the Spanish doctors have been providing scientific evidence to demonstrate that their innovative injury treatment does not result in any doping. The evidence, in form of extensive documentation that was first submitted to the Spanish Anti-Doping Agency, then to the Medical Commission of the International Olympic Committee and finally to the World Anti-Doping Agency, convinced the members of the WADA that the pioneering treatment of the two Spanish doctors is not performance enhancing.

Eduardo Anitua and Mikel Sánchez collaborate with the International Olympic Committee to establish the guidelines for Plasma Rich in Platelets used in Sport.

The meeting, which was attended by a large group of experts in different medical fields such as orthopaedic or sports medicine, aims to reach an agreement on guidelines for the application of plasma growth factors and their use in the treatment of sports injuries. Among other conclusions, all the meeting attendees recognized BTI and Eduardo Anitua as the pioneer in the development of this 100% autologous technique and Mikel Sánchez for its implementation in orthopaedic surgery and sports medicine, which has been proved to be the most effective in the treatment of tendon, ligament, intra-articular, …injuries.

BTI published an article of high scientific impact in International Journal of Periodontics and Restorative Dentistry

The aim of this study was to evaluate the influence of the length, diameter, and geometry of Biotechnology Institute dental implants on stress distribution in bone. Three-dimensional finite element models of osseointegrated titanium dental implants were created for this study. A force of 150 N was applied at an angle of 30 degrees. The four implant systems used were: Tiny, Interna Universal, Interna Plus, and Interna Wide, and presented the following platforms: 3.5, 4.1, 4.1 (with a 4.8-mm neck), and 5.5 mm, respectively. Implant lengths of 8.5, 10.0, 11.5, 13.0, and 15.0 mm and diameters of 2.5, 3.3, 3.75, 4.0, 4.5, and 5.0 mm were evaluated.

Results showed that the effect of implant diameter on stress distribution in bone was more significant than the effect of the implant’s length or its geometry. The maximum stress was located around the neck of the implant and the majority of the stress, independent of the parameter being studied, was distributed in the bone adjacent to the first six threads of the implant. Based on these finite element studies, the use of wider implants may be better to dissipate the acting forces and thus reduce the stress in the bone surrounding the implant. Additionally, the use of shorter and wider implants might be a reasonable alternative in sites limited by the height of the residual ridge.
