Dr. Sethi's Recommendation
"I recommend All-on-6 when the arch is large, the patient has strong opposing teeth, or when the bone allows comfortable placement of six implants. All-on-4 remains the gold standard for most patients - it's the most documented protocol in implant dentistry with 30+ years of data. Both deliver excellent outcomes."

The Bottom Line
- Choose All-on-4 if: Budget is a priority, bone is limited, and the All-on-4 evidence base matters to you
- Choose All-on-6 if: You want maximum stability, have a larger arch, or oppose natural teeth
