If you are missing multiple teeth or facing the prospect of losing all your teeth, you have likely come across two main implant-based solutions: All-on-4 and individual implants. Both are effective, long-lasting options, but they serve different needs and budgets. In this article, we compare the two approaches to help you understand which one may be the better fit for your situation.
What Is All-on-4?
All-on-4 is a full-arch dental implant solution that uses just 4 strategically placed implants to support an entire set of fixed teeth — typically 10 to 14 teeth on a single arch. Two implants are placed vertically at the front of the jaw, and two are angled at the back. This angled placement maximises contact with available bone, which means that many patients do not need bone grafting, even if they have experienced some bone loss.
A temporary set of teeth is often attached on the same day as surgery, so you leave the clinic with a functional smile. The final prosthesis — a custom-made, fixed bridge — is fitted 3 to 6 months later once the implants have integrated with the bone.
What Are Individual Implants?
Individual implants replace teeth one at a time. Each missing tooth gets its own titanium implant post and its own crown. This is the ideal approach when you are missing one to a few teeth that are scattered across different parts of your mouth. Each implant stands independently, mimicking the natural root structure of a single tooth.
All-on-4 vs Individual Implants: A Side-by-Side Comparison
| Factor | All-on-4 | Individual Implants |
|---|---|---|
| Best for | Missing most or all teeth in an arch | Missing 1 to a few teeth |
| Number of implants | 4 per arch | 1 per missing tooth |
| Bone grafting | Usually not required | May be required |
| Number of surgeries | Typically 1 | 1 per implant (can be combined) |
| Same-day teeth | Yes (temporary) | Sometimes (depends on case) |
| Treatment time | 3 to 6 months total | 3 to 6 months per implant |
| Longevity | 20+ years (implant post) | 20+ years (implant post) |
Cost Comparison at Trust Dental Surgery
One of the biggest differences between All-on-4 and individual implants is cost, especially when replacing a full arch of teeth.
| Option | Price | After Medisave |
|---|---|---|
| All-on-4 (per arch) | From $24,110 | From $18,800 |
| Osstem / Dentium implant (each) | $2,449 | $499 |
| Straumann implant (each) | $3,449 | $1,499 |
All prices are before GST (9%).
Example: If you need to replace 10 teeth using individual Osstem implants, the total would be $24,490 before Medisave (10 x $2,449). With All-on-4, the same arch can be restored from $18,800 after Medisave — a significant saving, with fewer surgeries and faster recovery.
Medisave for All-on-4
Since All-on-4 involves the surgical placement of 4 implants, Medisave can be claimed for the surgical component of each implant — up to $1,950 per implant. For 4 implants in a single arch, the total Medisave claim is approximately $5,310 (after deductibles). You can use your own Medisave or that of immediate family members (spouse, children, parents, grandparents, siblings).
For individual implants, the same Medisave claim of up to $1,950 per implant applies. At Trust Dental, we handle all Medisave paperwork for both All-on-4 and individual implant procedures.
Pros and Cons of All-on-4
Pros
- Cost-effective for full-arch replacement — replaces an entire arch at a lower cost than individual implants
- Fewer implants and surgeries — only 4 implants needed instead of 10+
- Same-day teeth — temporary teeth are often fitted on the day of surgery
- Usually no bone grafting — the angled implant design works with existing bone
- Shorter overall treatment time — typically completed within 6 months
Cons
- Not suitable for 1 or 2 missing teeth — it is a full-arch solution
- Prosthesis is one piece — if a section is damaged, the entire bridge may need repair
- Requires commitment to oral hygiene — cleaning underneath the fixed bridge requires special tools
Pros and Cons of Individual Implants
Pros
- Replaces teeth independently — each implant functions like a natural tooth
- Easy maintenance — brush and floss normally around each individual crown
- Flexible — you can replace one tooth now and add more implants later
- If one crown has an issue, it can be repaired independently without affecting others
Cons
- Higher total cost for multiple teeth — replacing a full arch individually is significantly more expensive
- More surgeries — each implant requires its own surgical procedure
- May require bone grafting — especially if bone has deteriorated after tooth loss
- Longer treatment time for multiple teeth — each implant needs its own healing period
Which Option Is Right for You?
The right choice depends on your specific situation:
- Choose All-on-4 if: You are missing most or all of your teeth in one or both arches, you want a cost-effective full-arch solution, you want teeth on the same day, or you want to avoid bone grafting.
- Choose individual implants if: You are missing 1 to a few teeth in different areas of your mouth, your remaining teeth are healthy, or you prefer each tooth to be independently replaceable.
In some cases, a combination approach may be best — for example, All-on-4 for one arch where most teeth are missing, and individual implants for the other arch where only a few teeth need replacing. Your dentist can help you evaluate the best strategy based on your oral health, bone condition, and budget.
