Edit: the original implant came loose, and after many problems I had to leave with a very bad result, hence now changed to 1 star. Incompetent dentist.
I had two implants with Dentium. The molar was good but unfortunately the incisor (the most important one) has been placed crooked. The dentist seemed very pleased with the work, which is concerning because it's obviously wrong. It took us 9 months to get to the point of finishing the implant, and then 10 seconds of clumsiness spoiled it - the crown was made too big, and despite me trying to explain this the dentist got me to bite hard on a pad, which pushed the tooth out to the front while the glue set. It now sticks out.
My confidence to smile has been affected by this, and even though most people don't recognise I've had an implant, I am very disappointed in the final result because of the difference in symmetry.
