RETRACTION: N. Lozano-Carrascal, R. A. Delgado-Ruiz, J. Gargallo-Albiol, J. E. Maté-Sánchez, F. Hernandez Alfaro, J. L. Calvo-Guirado, “Xenografts Supplemented with Pamindronate placed in postextraction sockets to avoid crestal bone resorption. Experimental study in Fox hound dogs”, Clinical Oral Implants Research 27, no. 2 (2016): 149–155, https://doi.org/10.1111/clr.12550

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 with another publication authored by the same group have been found, despite the articles have different study designs. Additionally, Figure 3c and Figure 4i derive from the same histological section, but used in different contexts. 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 J. L. Calvo-Guirado and co-author R. A. Delgado-Ruiz disagree with the decision of retraction. The first author N. Lozano-Carrascal states being unaware of these issues; however, this author disagrees with the decision for retraction based on the presented findings. Co-author Jordi Gargallo-Albiol states being unaware of these issues and concurs with the decision for retraction based on the presented findings. Co-author F. Hernandez Alfaro, citing their guest authorship status, claims complete unawareness of the research presented in the article and agrees with its retraction. The remaining co-authors were not available for a final confirmation of the retraction.
