I pre-paid for 6 implants but only received 4. I asked Dr Kur to provide the remaining 2 implants I had already paid for and he tried to extract an additional $5,000.00 from me to complete the work. I personally met with him and he was unable to complete a discussion as he became increasingly belligerent and left his conference room. He told me he would review the estimate and a week later I received an estimate of $13,000.00 to complete the work! This dentist is an arrogant, money hungry, unprofessional individual. I highly recommend avoiding this practice.
