Estudio histomorfológico de la capacidad de regeneración ósea del plasma rico en plaquetas, médula ósea y fosfato tricálcico. Estudio experimental en cerdos 'regeneración ósea en cirugía experimental en cerdos'

Abstract

ABSTRACT Objetive: On numerous occasions after the oral surgery bone defects occur which may be difficult to repair. Objective: We assessed the histomorphologic bone regeneration capacity of platelet-rich plasma at different concentrations, and extract bone marrow platelet-rich, compared with β-tricalcium phosphate. Material and Methods: We performed an experimental study in 8 pigs, who are practicing trepanaciones jaw to move the materials to study. The samples obtained were observed through electronic microscope and systematic photographs were made to analyse them through a system of gray histogram. Results: Ossification Phenomena were seen in 96% of the defaults practiced with independance of the material used to fill them. It is appreciated that the platelet-rich plasma (PRP) and bone marrow (M) show an equivalent degree of osteogenesis, 12.3 and 13.4 respectively, more power than the control. The platelet-poor plasma (PPP) provides a capability similar to controls (C) with an average of 14.03 and 14.12 abduction respectively. Tricalcium phosphate (FT) is effective as an inducer of ossification, 3.03 times more potent than the control. Conclusions: The ossification occurs in most of the charged defects. The PRP and the M are the most osteogenic capacity and the PPP is no more effective than control.
