Questions about this procedure?
Which Protocol Does Dr. Sethi Recommend?
Dr. Sethi recommends All-on-6 when the arch is large, the patient has strong opposing teeth, or the bone allows comfortable placement of six implants. All-on-4 remains the gold standard for most patients as the most documented protocol in implant dentistry, with a long track record of published outcomes. Both deliver excellent outcomes when matched to the right case.
