I was very nervous when I went in for my appt,but as I started reading paperwork for authorization I started having doubts about having the procedure done. I talked to the girls and to Dr. Keller and they informed me that its a standard thing,they have to list everything possible that could happen in result of having this done,and that most everything that is listed does not occur but they have to list it. Dr. Keller had stated that he performed two more implants on people earlier that morning. I went ahead and had the procedure and Dr. keller was able to also do the implant at the same time as the sinus lift which really speaded up the process for me.Everything seemed to go very smoothly and I was treated very well,which I usually am.I expected the whole procedure to last longer than it did,which I was very glad of. I want to Thank them all for making me feel at ease when having this done.
