I have nothing but high praise and admiration for Dr. Mastrovich and his incredible, in-depth knowledge and expertise in dentistry. He’s extremely trustworthy as well. I had a very complicated implant problem. My implant tooth broke off just below the gum line and the screw portion of the abutment was stuck inside the implant base. The dentist who had originally installed my implant wanted to charge me full price for a brand new implant and thousands just to extract the broken off screw. I sought a second opinion. Dr. Mastrovich used technology that he invented to extract the screw, and he was able to save the existing implant base. The cost was extremely affordable. I can’t thank him enough.
