Brief Summary

The primary outcome of periodontal reconstructive therapy is to regenerate all tissues of the periodontium including a functional periodontal ligament, alveolar bone and cementum. A number of treatment modalities including the use of bone grafts, guided tissue regeneration (GTR), and the addition of biological agents have been used with large heterogeneity in the clinical and histological outcomes. The rationale of using a filling material when treating unfavorable and large intrabony defects (IBDs) with membranes or biological agents consists of sustaining the overlying soft tissues in the presence of a non-contained defect's architecture, at the same time enhancing the stability of coagulum; and facilitating the proliferation of mesenchymal progenitor cells. Among bone grafts available, anorganic bone bone (ABB) have been widely used in periodontics for the treatment of IBDs In recent years, the increasing understanding of the role of growth factors (GFs) in the wound healing process suggested the use of these biological agents in the regenerative treatment of periodontal bony defects. Noninferiority trials are designed to demonstrate that the effect of a new treatment is adequately similar to an active control by more than a specified margin The aim of this study is to verify if the combined use of PRF (Platelet Rich Fibrin) and ABB in the management of IBDs may be a treatment modality that is clinically "not inferior" compared to the membrane + ABB one, since the combined periodontal regenerative technique has been already tested in literature as a "gold standard" periodontal regenerative technique.

Outcome Measures

Primary Outcomes (1)

  • Periodontal attachment gain

    Reduction of the distance between the cementum-enamel junction and the depth of the probable site

    1 year

Secondary Outcomes (1)

  • Bone gain

    1 year

Study Arms (2)

PRF+ABB treated patients

EXPERIMENTAL

Periodontal surgery with Platelet Rich Fibrin is performed, after local anaesthesia, mucoperiosteal SPPFs will be raised. Anorganic bovine bone material will be applied to the entire root surfaces ; then, A prf membrane is positioned above the filling material. Finally the flap will be positionated and sutures completed by interrupted sutures.

Procedure: Periodontal Surgery with PRF+ABB

Collagen Membrane + ABB treated patients
