Histological evaluation of a biomimetic material in bone regeneration after one year from graft.

Abstract

Aim: The use of substitute materials is one of the solutions used in periodontology for the reconstruction of intrabony defects. Advances in scientific research gave rise to a new generation of biomaterials of synthetic origin stoichiometrically unstable and therefore really absorbable. Our research is directed precisely towards a biomaterial synthesis, Engipore® (Finceramica, Faenza, Italy) which is a bone substitute of the latest hydroxyapatite-based generation, that possesses chemical and morphological properties similar to those of natural bone in the treatment of infrabony periodontal defects. Aim of this study was to evaluate the efficacy of Engipore® in the treatment of intrabony periodontal defects.

Methods: The study was conducted on 100 parodontopatics patients, which had gingival pockets of at least infrabonies 8/10 mm. The histological evaluation was performed with samples after one year from the graft.

Results: The histological samples collected after one year showed an abundant new bone formation, with mature lamellar bone tissue surrounding the residual particles of Engipore® that appear completely osteointegrated. The surrounding connective tissue shows no signs of inflammation.

Conclusions: The results obtained in our research demonstrated that, after a proper selection of patients and lesions, and applying an adequate surgical technique, this type of biomaterial in the treatment of periodontal defects acts in an optimal manner as a filler inducing the formation of new bone as evidenced by histological examinations.
