The All-on-4® treatment concept is the best in its class of solutions. But only when Nobel Biocare products are combined. Many have tried to mirror this groundbreaking concept, but only we have the scientifically documented success to back it up.

Proven long-term solution with high survival rates
Proven long-term solution with high survival rates

The All-on-4® treatment concept is a proven long-term solution with up to 10 years follow-up in the mandible and 5 years in the maxilla.1, 2

Cumulative survival rates are high in both edentulous maxilla and mandible.1, 2, 3, 4, 5, 6, 7, 8

  • Mid-term 3–4 years: 96.3–100% 4, 5, 6
  • Long-term 5–10 years: 94.8–98.0%1, 2
Favorable bone and soft bone tissue parameters
Favorable bone and soft bone tissue parameters

Stable marginal bone levels4, 5, 6, 7, 8 and healthy soft tissue5 both for tilted and axial implants.

Rapid improvement in quality of life
Rapid improvement in quality of life

Immediate implant loading with a fixed provisional prosthesis quickly leads to improved patient satisfaction – with regards to function, esthetics, sense, speech, and self-esteem.7, 8 In an OHIP (oral health impact profile) study, 95% of 250 patients were either extremely satisfied (74%) or satisfied (21%) with their new teeth. 98% said they would definitely recommend (88%) or consider recommending (10%) similar treatment to friends and colleagues.9

Other key findings
Other key findings
  • Shorter treatment times and reduced costs compared with conventional implant treatment modalities of the edentulous or soon-to-be edentulous jaw.10
  • Successful concept both in healed and extraction sites,8 also in combination with the treatment concept NobelGuide with guided drilling and implant insertion.12, 13
  • High stability with just four implants.14
