About

The use of injectable platelet-rich fibrin (i-PRF) in both surgical and non-surgical dental treatments has become increasingly widespread. Hard tissue grafts can produce "sticky bone," and bone gain can have a positive effect on intrabony defects frequently seen in periodontal disease, compared to grafts alone. This study aims to clinically and radiographically evaluate the effectiveness of using bovine-derived xenogenic bone grafts in combination with i-PRF and bovine-derived xenogeneic bone grafts alone in patients with intrabony defects and stage III periodontitis.

Full description

Intrabony defects are frequently observed in periodontitis patients. Bovine-derived xenogenic grafts are widely used in their treatment. To date, the graft has been mixed with various materials to increase its regenerative efficacy. In recent years, studies have explored its use in combination with PRF derivatives. Furthermore, with the introduction of i-PRF in regenerative treatments, its application with various biomaterials has been attempted. Applications have been made with materials such as demineralized freeze-dried bone allografts, hydroxyapatite bone grafts, and nanohydroxyapatite, with successful results. However, no studies have been conducted to date on the application of i-PRF with bovine-derived xenogeneic grafts in intrabony periodontal defects. This study aims to demonstrate that bovine-derived xenogeneic graft materials, which are frequently preferred by patients, achieve more successful results in various clinical and radiographic parameters in the treatment of intrabony defects, thanks to the contribution of i-PRF. The aims are to reduce clinical parameters that favor the treatment, increase bone fill, and minimize the defect area. It is thought that the use of I-PRF, a tissue-friendly biological material, will contribute to positive results in these parameters.

16 participants in 2 patient groups

i-PRF and xenogenic graft

Experimental group

Description:

In this treatment protocol, bone graft and i-PRF will be used instead of physiological saline. The preparation time for i-PRF (centrifugation) is 3 minutes. Two 9-mL tubes of venous blood will be collected from each patient.

Treatment:

Procedure: open flap debridement with I-prf and xenogeneic graft

Saline and xenogenic graft

Active Comparator group

Description:

A bovine-derived xenogeneic bone graft, which is routinely used for the treatment of intraosseous defects, will be applied. The graft will be mixed with physiological saline prior to application.

Treatment:

Procedure: open flap debridement with saline and xenogenic graft
