Artículo de revisiónLas perforaciones corticales, penetraciones intramedulares o decorticaciones se realizan a menudo como parte del procedimiento de regeneración ósea guiada (ROG). Su sustento biológico se basa en que mejorarían la angiogénesis y proporcionarían una vía hacia el hueso esponjoso rico en vasos sanguíneos.También se consideran como un "noxious stimuli" (estímulo nocivo) que iniciaría el fenómeno regional acelerado con una respuesta local exuberante facilitando la cicatrización ósea normal. Además, mejorarían la unión o enlace físico entre el injerto óseo y el lecho receptor asegurando estabilidad y fusión de los bloques óseos. Sin embargo, se nos presentan algunas interrogantes relacionadas a su fundamento, a los términos que las describen, a los tamaños, a su cantidad y disposición, al instrumental adecuado para realizarlas y al confort del paciente. Palabras clave: "regeneración ósea, cicatrización de heridas, neovascularización fisiológica"Cortical perforations, intramedullary penetrations or decortications are often performed as part of the guided bone regeneration (GBR) procedure. Their biological basis is that they would improve angiogenesis, providing a pathway to the medullar bone rich of blood vessels. In addition, cortical perforations would be consider as a "noxious stimuli" that initiate the accelerated regional phenomenon with an exuberant local response facilitating normal bone healing. Moreover, they would improve the physical bonding between the bone graft and the recipient bed ensuring stability and fusion of the bone blocks. However, there are some questions related to its foundation, terms to describe them, their sizes, quantity and disposition, the appropriate instruments to perform them and the comfort of the patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
