I was in a very desperate situation with the loss of my front tooth. There was major bone loss to the root due to an infection. Dr Walker told me we could try to do a bone fill and see if the implant would take. If things did not work out, he would refund my money and recommend for bridge work instead. I chose to try the implant procedure. The implant and the subsequent crown procedure by Dr Eric Werner was a resounding success. Dr. Walker is a very fine oral surgeon with the upmost integrity. I recommend both Dentists without reservation.
