Corrigendum

In (Bratu et al. (2009), the institutional affiliation of Emmauel A. Bratu was listed as below on page 827:

Department of Implant Restorations, University of Medicine and Pharmacy, Timisoara, Rome, Italy

It is incorrect and should have been:

Department of Implant Restorations, University of Medicine and Pharmacy, Timisoara School of Dental Medicine, Timisoara, Romania.

The authors would like to apologize for this error.
