Full arch on four implants

Some full-arch plans use four implants: two straight at the front and two tilted at the back to make use of available bone. Straumann's Pro Arch concept includes four-implant restorations.1

In short
  • Four implants, back ones often tilted.
  • 'All-on-4®' is a trademark of another manufacturer; we describe the approach instead.
  • Four is not automatically better or worse than six. It depends on the anatomy.

Four or six implants?

Four implants can support a fixed arch when bone and bite allow. Six or more may be chosen for larger arches, heavier bites or reduced bone quality. Your surgeon will explain the reasoning.
