For patients who've lost most or all of their teeth in one arch, All-on-4 and All-on-6 protocols offer a full-arch solution anchored by a small number of strategically placed implants, rather than replacing every tooth individually.
How it works
Four (or six) implants are placed at carefully calculated angles that maximize contact with available bone, then a full custom-fabricated arch of replacement teeth is attached to those implants. This provides full-arch function and appearance without requiring an implant for every missing tooth.
All-on-4 and All-on-6 are frequently more cost-effective per replaced tooth than individual implants, precisely because fewer implants are doing the structural work for an entire arch.
All-on-4 vs. All-on-6
All-on-6 uses two additional implants for extra support, generally recommended for patients with lower bone density or higher bite-force needs. Your specific candidacy depends on imaging and bone assessment done during consultation — not a preference you choose independently of your anatomy.
The realistic timeline
- Visit 1: Implant placement surgery, often with a temporary set of teeth attached the same day
- Healing period: 3–6 months for osseointegration (the implants fusing with bone)
- Visit 2: Final custom arch fitted and attached, once healing is confirmed complete
Planning the trip around this
This is one of the clearer cases where a two-trip approach is standard, not optional — see our trip planning guide for how to structure both visits.
