ANSWERS

What is the difference between All-on-4 and All-on-6?

All-on-4 restores a full arch on four implants, with the two posterior implants tilted up to 45 degrees to avoid grafting. All-on-6 uses six implants, typically placed vertically, distributing load across more anchor points. All-on-4 reduces surgical complexity and bone-graft cases;

More on this topic

When should I choose All-on-6 over All-on-4 for a full-arch case?

All-on-6 is generally preferred when bone volume supports six vertical implants, when the patient has heavy occlusion or parafunction, or when you want additional posterior support to reduce cantilever length. All-on-4 remains a solid option for atraumatic bone or immediate load protocols where tilted posterior implants avoid the sinus or mental foramen. Case selection depends on your surgical plan, opposing dentition, and long-term prosthetic goals.

Which prosthetic materials does Dani fabricate for All-on-4 and All-on-6 cases?

We fabricate full-arch implant prosthetics in monolithic zirconia, layered zirconia with pink ceramic, and hybrid designs with acrylic on a titanium bar. Material selection depends on interocclusal space, opposing arch, and esthetic demands. For high-stress cases or bruxers, monolithic zirconia is common. For maximum esthetics in the smile zone, layered zirconia with characterized pink work delivers a natural transition.

What records does Dani need to design a full-arch restoration?

We need a verified master impression or intraoral scan with scan bodies, a bite registration or vertical dimension record, a CBCT when available, and photos including full-face and retracted views. For conversion or final prosthetics, we also request the provisional or a wax try-in reference. Clear communication on tooth shape, shade, and midline preferences helps us match the patient's esthetic goals on the first delivery.

How does the cantilever differ between All-on-4 and All-on-6 prosthetics?

All-on-4 typically requires a distal cantilever behind the posterior tilted implants, which we keep conservative to protect the prosthesis and implants from off-axis load. All-on-6 distributes load across additional anchor points and usually allows a shorter cantilever or none at all. During design, we evaluate implant positions, arch form, and opposing occlusion to specify a cantilever length that supports long-term prosthetic stability.

Can Dani support both immediate load conversions and definitive full-arch prosthetics?

Yes. We support the full workflow from surgical planning references through immediate load conversion prosthetics and definitive restorations in zirconia or hybrid designs. For conversions, quick turnaround and clear communication on implant positions are critical. For definitive cases, we coordinate try-ins, verification jigs when indicated, and final delivery to confirm passive fit, occlusion, and esthetics before the patient leaves the chair.
