All-on-4 Dental Implants in Shanghai: Guide for International Patients | Deepnav Health

What Is All-on-4 Dental Implant Treatment?

All-on-4 is a full-arch restoration technique that uses four strategically placed dental implants to support a complete bridge of replacement teeth. Developed to maximize the use of available bone, this approach often eliminates the need for bone grafting and allows patients to receive temporary teeth on the same day as implant surgery.

For international patients considering All-on-4 treatment in Shanghai, this guide explains what to expect.

How the All-on-4 Procedure Works

Step 1: Consultation and Planning

Your implant specialist performs a comprehensive evaluation including CBCT 3D imaging to assess bone quality and plan implant positions. Digital treatment planning software helps determine the optimal placement for each implant.

Step 2: Implant Placement Surgery

Four implants are placed in each arch — two straight implants in the anterior region and two angled implants in the posterior region. The angled posterior implants maximize contact with available bone and avoid anatomical structures. Surgery typically takes 2–3 hours per arch.

Step 3: Immediate Loading (Same-Day Teeth)

In most cases, a temporary fixed bridge is attached to the implants on the same day as surgery. This means patients leave the clinic with functional teeth and do not need to go without teeth during the healing period.

Step 4: Healing Period

Over the next 3–6 months, the implants fuse with the jawbone (osseointegration). Patients follow a soft food diet during the initial healing phase.

Step 5: Final Bridge Placement

Once healing is complete, the temporary bridge is replaced with a custom-crafted final prosthesis made from high-strength materials like zirconia or porcelain-fused-to-metal.

Who Is a Candidate for All-on-4?

All-on-4 may be suitable for patients who:

Have lost all or most teeth in one or both arches

Have moderate bone loss that might require grafting for traditional implants

Want a fixed solution rather than removable dentures

Are in good general health for elective surgery

Want a faster treatment timeline compared to traditional approaches

A thorough clinical evaluation is necessary to confirm candidacy.

Benefits of All-on-4

Fewer implants — Only 4 per arch vs. 6–8 for traditional approaches

Often no bone grafting needed — Angled implants maximize existing bone

Same-day teeth — Immediate function and aesthetics

Fixed solution — More stable and comfortable than removable dentures

Cost-effective — Fewer implants and often fewer surgical visits

Recovery and Aftercare

After All-on-4 surgery, patients should expect:

Swelling and mild discomfort for 3–5 days, managed with prescribed medication

A soft food diet for 6–8 weeks while implants heal

Regular follow-up visits to monitor healing

Good oral hygiene practices to maintain implant health

Common Questions About All-on-4

How long does All-on-4 last? With proper care and maintenance, All-on-4 restorations can last 15–20 years or longer. Regular checkups and good oral hygiene are essential.

Is the surgery painful? The procedure is performed under local anesthesia or sedation. Most patients report manageable discomfort after surgery that resolves within a few days.

What is the difference between All-on-4 and All-on-6? All-on-6 uses six implants per arch for additional support. The choice depends on bone availability and the specialist's recommendation.

Can I fly home soon after surgery? Most patients can travel 3–5 days after surgery once initial healing is confirmed. Your implant specialist will advise on the appropriate timing.
