The All-on-4 Procedure: What to Expect

The All-on-4 dental implant procedure is a same-day full-arch restoration that replaces an entire row of teeth using just four strategically placed implants. Here's a detailed look at every step of the process.

Pre-Treatment: Remote Consultation

Before you travel to Mexico, you'll have a remote consultation with your implant specialist. You'll send a panoramic X-ray or CBCT scan (your local dentist can take one for $100-$200). The specialist will:

Step 1: Arrival and Assessment (Day 1)

When you arrive in Los Algodones (or your chosen destination), you'll visit the clinic for a comprehensive in-person evaluation. This typically includes:

Most clinics arrange airport pickup and hotel accommodations. Los Algodones is a small town where everything is within walking distance — you can literally walk across the border from Yuma, Arizona.

Step 2: Implant Surgery (Day 2-3)

The surgical procedure is the core of the All-on-4 treatment. Here's what happens:

  1. Anesthesia — Local anesthesia is applied (or IV sedation if you chose it). You'll be comfortable throughout.
  2. Tooth extraction — If you have remaining teeth in the arch being treated, they're removed at this time.
  3. Implant placement — Four titanium implants are placed per arch:
    • Two implants straight in the front of the jaw
    • Two implants angled at 30-45 degrees in the back
    • The angled placement maximizes bone contact and avoids the sinus (upper) or nerve canal (lower)
  4. Abutment attachment — Connector pieces (abutments) are attached to the implants immediately.
  5. Impressions — Digital or traditional impressions are taken for your temporary teeth.
  6. Temporary teeth — A fixed acrylic bridge is created and attached to the implants the same day. You leave with functional teeth.

The entire process takes 2-3 hours per arch. If you're doing both arches, it may take 4-5 hours total.

Step 3: Follow-Up and Healing (Days 4-7)

Over the next few days, you'll have 1-2 follow-up appointments to check healing, clean the surgical site, and adjust your temporary teeth if needed. Most patients return home within a week of surgery.

Step 4: Osseointegration (3-6 Months)

During this period, the titanium implants fuse with your jawbone — a process called osseointegration. You'll wear your temporary teeth and eat a modified diet. Virtual check-ins with your dentist keep everything on track.

Step 5: Final Prosthesis (Return Trip)

After osseointegration is complete, you return to Mexico for 2-3 days. The temporary teeth are removed and replaced with your permanent prosthesis — typically a precision-milled zirconia or high-quality acrylic bridge. This is your final, permanent set of teeth.

The 3-ON-8™ Alternative

Dr. José Moguel developed a patented alternative called 3-ON-8™, which uses three implants per arch with a unique distribution protocol. This may be recommended for specific cases where All-on-4 isn't ideal. Learn more about this option in our treatment comparison guide.
