Quick answer
The short answer
All-on-4 and All-on-6 both give you a fixed full arch of teeth. All-on-4 uses four implants – two of them angled – so it needs less bone and often avoids grafting. All-on-6 uses six implants, spreading the bite load for extra stability, but needs more bone. At Dent KM, All-on-4 starts from €3,150 and All-on-6 from €4,150 per arch.

You don't have to choose alone. The dentist decides from your X-ray or 3D scan, considering bone volume, bite and your expectations. Send your X-ray or photos and we'll recommend one, with a fixed written price, free of charge.
