Today we propose you an interesting article published in the Journal of Contemporary Dental Practice that shows the long-term results of regeneration of periodontal defects in 22 patients with enzymatically treated equine bone graft and collagen membrane (Biocollagen®). The graft used (Bio-Gen®) is produced by a variant of the Zymo-Teck® enzymatic process that allows to preserve the collagen in hydrolyzed form and the mineral component unaltered. The defects considered were 1-2-3 walled with a pocket depth > 5mm. The evaluation of regeneration included the measurement of plaque index, pocket probing depth, clinical attachment level, and sulcus bleeding index at 12 months, 24 months, and 13 years of follow-up. Results at each follow-up showed a 50% decrease in pocket depth....

Today we propose an interesting article published in the Dentistry Journal that compares the regenerative and chemical/physical properties of collagen-preserved equine bone (Osteoxenon®) with those of anorganic bovine bone (ABB). While Osteoxenon® is produced with the Zymo-Teck® enzymatic process that preserves collagen in its native form, ABB is produced by a high-temperature heat treatment that removes the collagen component and alters the mineral component. The regenerative performance of the two biomaterials was evaluated histologically in 46 patients in whom socket preservation surgery was performed. The physical/chemical characterization was performed by infrared spectroscopy and protein identification by SDS-PAGE technique. The results demonstrated the presence of preserved collagen in Osteoxenon® and how this allows to obtain a statistically higher percentage of newly formed bone...
