Preservación alveolar mediante plasma rico en plaquetas y fibrina rica en plaquetas. Un análisis comparativo.

Abstract

Tissue regeneration was only an idea, which with the passage of time and the advancement of the sciences has been developing and structuring itself better, platelet concentrates and derivatives have demonstrated their influence on tissue neoformation and their contribution to better healing of the tissues. Objective: To compare bone intensity in gray scale by computed tomography of alveoli of lower third molars in post-extraction controls, performing alveolar preservation with platelet rich plasma (PRP) and platelet rich fibrin (FRP). Materials and methods: a non-randomized controlled clinical trial was carried out in which the population and sample were 10 patients (3 men and 7 women) who attended the clinic of the Universidad Antonio Nariño, based in Palmira, with indications of tooth extractions of lower third molars bilateral. The respective dental extractions were performed, with alveolar preservation of one of the alveoli using PRP or FRP, leaving the other alveolus without preservation as a control group. At the end a comparative analysis of the two methods was carried out. Results: both materials showed a mild improvement in bone regeneration, although the material with the best results was FRP, showing greater graft consolidation and greater mineralization, but this difference is not very statistically significant. Conclusions: when used as post-extraction alveolar preservation methods of lower third molars, PRP and FRP showed a mild improvement in bone density in the controls performed.
