This orthodontic surgeon should not be allowed to practice. His treatment of me was grossly negligent; he badly injured me, then tried to cover it up. In detail-- I had sinus augmentation with bone graft to prepare me for two implants. When he could not gently remove the screw on the temporary post, he forcibly removed it, breaking the bone, and creating a hole into my sinus cavity. Then, instead of admitting his mistake, he made believe I wasn’t injured. All five of my subsequent treating physicians have stated, that had he just admitted to his mistake and put me on antibiotics, I might have been okay. Instead I have an infection in my sinuses that I will most likely have for the rest of my life. When I approached him about this, he told me that all my other doctors were liars or wrong; that I didn’t have an infection, and that if I did it wasn’t his fault. He refused to admit to his mistake, or take responsibility for his actions. This is not the kind of dental surgeon you want to treat you. Stay clear!!
