ABSTRACT
Introduction:
Bone defects are rather common after oral surgery and may prove difficult to repair.Objective:
Weprovide a histomorphological analysis of the bone regenerative capacity of platelet-rich plasma at different concentrationsand the extraction of platelet-rich bone marrow, compared with &bgr;-tricalcium phosphate.Methodology:
We performed an experimental study on 8 pigs, in which we performed trepanations of the mandible inorder to place the materials to be studied. Using an electron microscope, we observed the samples obtained andtook a series of photographs in order to analyze the samples through a gray-scale histogram system.Results:
Ossification phenomena were present in 96% of the charged defects, regardless of the material used to fillit. Platelet-rich plasma (PRP) and the bone marrow (M) showed an equivalent degree of osteogenesis, 12.3 and 13.4respectively, which is greater in than the control group. The platelet-poor plasma (PPP) shows a capacity similarto the control groups (C), with an average count of 14.03 and 14.12 respectively. Tricalcium phosphate (TP) wasshown to be effective as an ossification inducer, 3.03 times stronger than the control group.Conclusions:
Ossificationoccurs in most of the charged defects. PRP and M had the greatest osteogenic capacity but PPP was nomore effective than the control (AU)RESUMEN
