Question

in 12/september 2006 made screw implant in 1/1 <> two stage (USA), but the dentist put them not good alittle forth-putting from all teeth, in 5 january 2007 he put the crowns 1/1.

because the crowns are forth-putting one tooth was break.

Answer 1

ONCE THE SCREWS HAVE INTERATED INTO THE BONE THEY'RE IMPOSSIBLE TO REMOVE.
WHAT CAN BE CHANGED IS THE MOUNTS THAT ARE ATTACHED TO THE IMPLANTS, AND THE WAY THE TEETH COME TOGETHER.
THE DENTIST HAS ALL THE WRITTEN DOCUMENTATION FOR THE TYPE OF IMPLANT THIS IS.
