Microscopic characterization of national bone matrices for the reconstruction of lost bone structures in Dentistry

Objective. Morphologically characterize the ultrastructure of some nationally manufactured bone matrices available in the local commercial market in order to determine the main characteristics that allow their use in the dental rehabilitation of atrophic bone ridges. Methods. Bone matrices from Free...

Morphologically characterize the ultrastructure of some nationally manufactured bone matrices available in the local commercial market in order to determine the main characteristics that allow their use in the dental rehabilitation of atrophic bone ridges. Methods. Bone matrices from Freeze-Dried Human Bone (HHL) provided by the Laboratory of Blood Products of the National University of Córdoba were studied, with block and powder format whose particle size is from 200 to 1000 μm and in the form of fine granules of 1000 at 2000 μm. The samples were respectively metalized with a layer of gold or chromium and were analyzed in a scanning electron microscope (SEM). Results. A structure of HHL bone similar to that observed in the spaces of the Haversian blood vessel system of normal human bone was observed. Conclusions. The structural findings of the HHL bone, similar to those observed in the spaces of the Haversian blood vessel system of normal human bone, guarantee the topographic conservation responsible for the increase of the surface area and consequently a large surface-volume ratio that favors repair and regeneration. Bone with favorable characteristics is used as a graft. In addition, maintaining the nanostructure of the extracellular matrix gives it greater roughness, allowing greater anchorage that favors better cell growth by presenting essential topographic signals, benefiting adhesion, proliferation and differentiation of cells Objetivo. caracterizar morfológicamente la ultra estructura de algunas matrices óseas de fabricación nacional disponibles en el mercado comercial local a fin de determinar las principales particularidades que permitan su uso en la rehabilitación odontológica de los rebordes óseos atróficos. Métodos. Se estudiaron matrices óseas provenientes de Hueso Humano Liofilizado (HHL) provistas por el Laboratorio de Hemoderivados de la Universidad Nacional de Córdoba, con formato de bloque y de polvo cuyo tamaño de partícula es de 200 a 1000 μm y en forma de gránulos finos de 1000 a 2000 μm. Las muestras se metalizaron respectivamente con una capa de oro o cromo y fueron analizadas en un microscopio electrónico de barrido (MEB). Resultados. Se observó una estructura del hueso HHL similar a los observados en los espacios del sistema de vasos sanguíneos Haversiano del hueso humano normal. Conclusiones. Los hallazgos estructurales del hueso HHL, similares a los observados en los espacios del sistema de vasos sanguíneos Haversiano del hueso humano normal, garantizan la conservación topográfica responsable del incremento del área superficial y consecuentemente de una gran relación superficie-volumen que favorece la reparación y regeneración ósea constituyendo características favorables para ser utilizadas como injertos. Además, el mantenimiento de la nanoestructura de la matriz extracelular le otorga mayor rugosidad, permitiendo un mayor anclaje que favorece un mejor crecimiento celular por presentación de señales topográficas esenciales, beneficiando la adhesión, proliferación y diferenciación de las células.
