Effects of an injectable platelet-rich fibrin on osteoblast behavior and bone tissue formation in comparison to platelet-rich plasma

Platelets, 2018
Platelet-rich plasma (PRP) has been utilized for many years as a regenerative agent capable of inducing vascularization of various tissues using blood-derived growth factors. Despite this, drawbacks mostly related to the additional use of anti-coagulants

PRF in der Zahnmedizin

SWISS DENTAL JOURNAL SSO – Science and Clinical Topics, 2018
Platelet-rich-Fibrin (PRF) bezieht sich auf einen Bestandteil des natürlichen Blutes. Die sogenannte Fibrinmatrix ist angereichert mit Blutplättchen (Thrombozyten). Die Herstellung ermöglicht den Gewinn von PRF in Form einer Matrix oder eines Gels aus dem eigenen Blut und anschliessend die Applikation an entsprechend gewünschter Region.

In vitro ultrastructure and biodegradation of activated plasma albumin gel derived from human samples: A prospective observational study

Clinical Advances in Periodontics, EarlyView.
Abstract Background In soft tissue regeneration, the clinical efficacy of fibrin membranes has been a pressing concern. The key to this efficacy lies in the stability of membrane and its controlled absorption. Human serum albumin, with its influence on the formation and stability of fibrin networks, could hold the key to developing a more stable ...

Crestal approach for repair of oroantral bone defects and subsequent implant placement

Clinical Advances in Periodontics, EarlyView.
Abstract Background Oroantral communication (OAC) can occur after a dental extraction. Occasionally, bony defects may persist despite successful soft tissue closure of the OAC. The absence of bone in these areas poses challenges for dental implant placement.
