Had a bottom implant done a year ago, went for adjustment few times, no one knows what they are doing , kept telling them the pin on left side is higher than the right side, of course they said nothing wrong with it , take the implant , whatever they did with it is not helping, the right fits very well, but left is very bad, will never refer aspen dental and told my friends never to go there. User's recommendation: never to go to aspen dental.
