Injerto de hueso humano no autólogo aplicado a la elevación del seno maxilar superior.

Abstract

The objective of this study was to evaluate the effectiveness of the use of non-autogenous human bone using the maxillary sinus floor elevation technique to create favorable conditions for the placement of dental implants. Longitudinal clinical study of partially edentulous patients of both genders (included in this study n = 11), older than 18 years. The data were recorded in three time periods: a) at the time of operation: b) control at 7 days, c) control at 180 days, these last two postoperative. The human bone grafts used were lyophilized and irradiated, with a particle size of 0.2 and 1 mm, manufactured by the Hemoderivatives of the National University of Cordoba. The increase in bone tissue was measured by digital orthopantomography, as the distance obtained between the lower basal edge and the resulting alveolar ridge. The population was composed of 8 women and 3 men. The increase in bone reached, at 7 and 180 days, was observed radiographically. There was a significant increase in the mean values of bone mm. Variations were 4-8 mm at the time of operation at mean values of ? 14 mm at 7 and 180 days after surgery.The results indicate that lyophilized human bone can be considered an alternative to bone grafts of animal origin or those of patients.
