All-on-4® Vs Overdentures: Which Is Better?

Make an informed decision on which may be best for you!

What Are Overdentures?

Traditional full dentures replace all upper or lower teeth, while partial dentures replace only a few missing teeth. They are removable and sit on the gums using adhesive. Although long-lasting, ongoing jawbone shrinkage can reduce stability over time, causing movement when eating or speaking and potential gum irritation or ulcers.

Overdentures are dentures secured to dental implants, which act as anchors to hold them firmly in place. This added stability allows for greater bite force, improved control when eating and talking, and makes it easier to enjoy harder foods compared to traditional dentures.

What Are All-on-4®?

Developed by Professor Paulo Malo in collaboration with Nobel Biocare, All-on-4® is an advanced, long-term solution for patients who have lost most or all of their teeth.

The technique uses four strategically placed titanium implants to support a full arch of fixed teeth. Two implants are placed at the front and two at a 45° angle at the back, maximising support while avoiding nerves and sinuses. This often allows patients with reduced bone density to avoid bone grafting.

Because the bridge is securely fixed, All-on-4® is a permanent, non-removable solution that looks, feels, and functions like natural teeth.

Key Differences: All-on-4® vs Overdentures

Both treatments restore missing teeth and help maintain jawbone health, but there are some important distinctions:

Permanence:
- All-on-4^® – Fixed in place and not removable by the patient.
- Overdentures– Removable for cleaning and sleeping.
Comfort & Stability:
- All-on-4^® – Feels and functions like natural teeth; no adhesives needed.
- Overdentures – More stable than traditional dentures but may move slightly.
Maintenance:
- All-on-4^® – Clean like natural teeth with brushing, flossing and regular check-ups.
- Overdentures – Remove daily for cleaning; implants and attachments require routine care.
Aesthetics:
- All-on-4^® – Fully fixed bridge designed to look and feel like a natural smile.
- Overdentures – Removable but still offer an improved aesthetic compared to traditional dentures.
Cost & Treatment Time:
- All-on-4^®– Higher upfront cost but long-term value with fewer maintenance needs.
- Overdentures– Lower initial investment, though attachments may need replacing over time.

Which Option Is Right for You?

The best solution depends on your lifestyle, oral health, and budget.

Choose All-on-4^® if you want a permanent, fixed solution that feels and functions like natural teeth and allows you to eat confidently without worrying about movement or adhesives.
Choose a removable option – such as overdentures – if you prefer something you can take out, or if you’re seeking a more budget-friendly treatment while still gaining the benefits of implant support.

Your dentist or implant surgeon can help determine which approach best suits your needs after a detailed consultation, including scans and a review of your medical and dental history.
