Abstract

M. P. Ramírez-Fernández, J. L. Calvo-Guirado, J. E. Maté-Sánchez del Val, R. A. Delgado-Ruiz, B. Negri, C. Barona-Dorado, “Ultrastructural study by backscattered electron imaging and elemental microanalysis of bone-to-biomaterial interface and mineral degradation of porcine xenografts used in maxillary sinus floor elevation,” Clinical Oral Implants Research 24, no. 5 (2013): 523–530, https://doi.org/10.1111/j.1600-0501.2011.02414.x.

The above article, published online on 26 January 2012 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Lisa J. A. Heitz-Mayfield; and John Wiley & Sons Ltd. The retraction has been agreed due to concerns raised by third parties on the data presented in the article. Several flaws and inconsistencies between results presented and experimental methods described were found. Specifically, instances of overlapping data within the article and with another publication authored by the same group have been found, despite the articles have different study designs. Accordingly, the editors consider the findings of this article unreliable and the conclusions to be invalid. The authors have been informed of the decision to retract the article. The corresponding author M. P. Ramírez-Fernández and co-author R. A. Delgado-Ruiz disagree with the decision of retraction. The remaining co-authors were not available for a final confirmation of the retraction.
