Description Aim: Determine bone density and height reached fifteen (15) days and three (3) months after being grafted an sockets with a synthetic bone substitute and compared with experimental ceramic biocomposite.
Materials and Methods: Thirty-seven sockets (37) selected randomly were grafted in clinics of the University of Valle, sixteen sockets (16) for control group and twenty (21) for the experimental group. CT scans were performed at 15 days and 3 months post-surgery determining bone levels: vertical height and width in the grafted area; bone density is also determined by analyzing Hounsfield units. The information obtained was processed with the STATA version 13 application frequencies for gender, type of socket and type of graft used, and for numeric variables of age, bone density, bone height, thickness crestal, averages were established and deviation were calculated standard. The confidence level was set at 95% and the significance level of 5%.
Results: Bone density and height, no statistically significant differences between the intervention group (group 1) and control (group 2). For peak thickness statistically significant differences (p<0.05). The variation or change between start and end of follow within each group found that there is no statistically significant difference.
Conclusions: The ceramic biocomposite with chitosan and graft tricalcium phosphate and hydroxyapatite no statistically significant differences in density and height in the scans at 15 and 90 days. The bone width showed statistically significant differences.

Objetivo: Determinar los niveles de altura y densidad osea alcanzada en alvéolos postexodoncia, 15 dias y tres meses después de ser injertados con un sustituto óseo experimental.
Materiales y Métodos: Se distribuyeron aleatoriamente 37 alvéolos postexodoncia en dos grupos, uno experimental (n=21) y otro control (n=16). En el grupo experimental se utilizó un material compuesto por β-Fosfato tricalcico y quitosano, en el grupo control se empleó un producto comercial compuesto por una mezcla bifásica de hidroxiapatita (HA) y fosfato tricalcico (TCP). Se realizaron tomografías a los 15 días y 3 meses postquirúrgicos determinando niveles óseos (altura y anchura en la zona injertada); también se determinó la densidad ósea utilizando unidades Hounsfield. La información obtenida se procesó con la aplicación STATA versión 13. Se calcularon frecuencias para el sexo, tipo de alvéolo y tipo de injerto utilizado, y para las variables numéricas de edad, densidad ósea, altura ósea, grosor crestal, se establecieron promedios y desviación estándar. El nivel de confianza se estableció en 95% y el nivel de significancia en 5%.
Resultados: Al comparar la densidad y altura ósea en los dos grupos no se encontraron diferencias estadísticamente significativas, pero si al comparar el ancho en la zona de la cresta (p<0.05).
Conclusiones: El biocompuesto cerámico con quitosano mostró ser útil en preservar niveles óseos en los alvéolos postexodoncia y presentó diferencias estadísticamente significas en el ancho del reborde.
