Response from corresponding author A Ayoub to a letter to the Editor (D-09-00044) regarding article 'How accurate is model planning for orthog-nathic surgery?'

摘要

Dear Editor,We acknowledge that similar research was published in 2004 in the French lit-erature, which we did not review. We agree that the errors in model surgery planning are multi-factorial and start with the inaccuracy of using 2D cephalometric analyses.We also agree that the utilisation of generic hinge axis articulators is not ideal for orthognathic surgery planning. We disagree that the surgeon has no control over the rotations and translations required for model surgery planning. We showed in our article that with the use of the newly-developed orthognathic articulator, rotations across the x, y and z axes could be measured.We acknowledge that we did not review the French literature, which was beyond the scope of our literature search. We are in agreement that 3D cephalometric analysis is the way forward, but this was not an area of investigation in our published article.
