Abstract

OBJECTIVES Platelet derivates are widely used for tissue regeneration, in dentistry and beyond, with shorter healing time and fewer side effects associated with the surgical trau-ma or with pathologic conditions. They are autologous products ob-tained from a little amount of ve-nous blood, through manipulation with closed circuit systems. Among these, L-PRF has a safe and promising use in the dental field. It can be used alone or to-gether with other materials and is, due to its peculiarities, the most used among the blood components in oral surgery. This paper has the aim to make an overview about the various ap-plications of the platelet deriva-tives in the dental field. Moreover, three clinical cases managed with L-PRF will be presented. MATERIALS AND METHODS Three clinical cases have been se-lected among those managed at the Oral-Maxillofacial Surgery Unit, at the Policlinico of Modena, Italy. Case 1: one patient with third mo-lar impaction, 3.8.
