Experts present a new biomaterial to improve the quality of the fabrics perimplantarios without autografts.

-Faced with the connective tissue graft matrix collagen allows early scarring, less sense of pain, prevents hemorrhages and reduces the need to take anti-inflammatory drugs and analgesics

-perimplantitis is a common problem that affects to the implants and causes to lose bone

Madrid, April of 2011- the matrix collagen may soon be used by all dentists as an alternative to the inconvenience and pain arising from connective tissue graft. Dr. Fabio Vignoletti, researcher hired by Universidad Complutense de Madrid and a specialist in periodontics and implants the clinic Periocentrum Madrid, presented the results of pre-clinical and clinical studies that demonstrate the advantages of the use of this new material at the Cannes Osteology Symposium on dental implants.

Perimplantitis is a common problem that affects to implants dental, causing to lose bone and reducing its useful life. In certain clinical situations, to prevent perimplantitis dentists come to make a speech which consists in the increase of the keratinized gingiva. The usual technique is take a part of gingiva of the palate and adapt it to the area of the implant; Thus the increase of keratinized gingiva is obtained. However, this type of autograft causes sensation of pain in the patient, can cause bleeding late and needed two areas of surgical intervention ”, explains Dr. Vignoletti.

Prof. Mariano Sanz, Dean of the Faculty of Dentistry of the University Complutense of Madrid, and the experts of the Periocentrum Dr. Ramón Lorenzo clinic and Dr. Fabio Vignoletti, that are part of his research team have been the first to compare the graft of connective tissue with the new matrix collagen in two controlled clinical trials, randomised, parallel. The researchers noted the use of the collagen matrix allows an early healing, the patient will feel less sensation of pain, reduces the possibility of producing bleeding and the need for analgesics or anti-inflammatory drugs. Thus, to analyze the times of healing they discovered that any sensation of pain with the use of the new biomaterial disappeared a week or ten days earlier in the connective tissue graft and, therefore, the patient’s recovery was much faster.

The use of the collagen matrix will help us to improve the quality of tissues in different clinical situations around implants of our patients, it is a way of preventing the development of perimplantitis and assure more long-term health ”, says Dr. Vignoletti. This specialist has already used the new material in several pilot experiences in the clinic Periocentrum Madrid, but the matrix collagen is not marketed in Spain up in a few months.

The Osteology International Symposium, organized by the Osteology Foundation, has brought over 3,000 specialists in Cannes. The regeneration of tissue, the management of risk factors and of complex cases, the latest results in bone regeneration and new treatments and products for the increase of soft tissue are issues that raise interest in the field of the Periodontics and implants dental and that they have been addressed in these workshopsamong other matters related to tooth regeneration.
