Are All-on-4 implants better than dentures?

Clinically, yes — for patients who are candidates. All-on-4 is fixed (no removal), preserves jaw bone by providing mechanical stimulation, provides stronger bite force, and feels like natural teeth. Dentures are removable, allow bone resorption to continue, and can move during eating. But All-on-4 requires surgery, osseointegration time, and higher upfront cost — dentures are appropriate for patients who are not implant candidates or have budget constraints.

Can I upgrade from dentures to All-on-4 later?

Yes, but it is more complex. Prolonged denture wear causes bone resorption — the jaw shrinks without tooth root stimulation. Bone grafting before All-on-4 may be needed after years of denture wear. Planning All-on-4 from the outset (before significant bone loss) is clinically preferable if budget allows.

Does Medicare cover dentures or All-on-4?

Medicare does not cover full dentures or implants for adults. Some state government dental schemes cover emergency denture work for concession holders. Private health extras typically provide AUD 500–1,500 rebate for dentures and minimal rebate for implants.

What is an implant-retained overdenture?

A middle option — 2–4 implants placed in the lower jaw provide attachment points for a removable denture. The denture clips on for stability and off for cleaning. It costs AUD 4,246–AUD 5,660 at Picasso versus AUD 9,000–AUD 22,000 in Australia, and significantly reduces the stability problems of conventional lower dentures.

All-on-4 vs dentures: a cost and quality comparison for Australian patients

All-on-4 implants are fixed permanently and preserve jaw bone. Dentures are removable and lower cost. Full comparison with Australian private and Picasso Vietnam prices.

Dentures are removable custom-fitted plates that replace missing teeth at a lower upfront cost. Australian private full dentures cost AUD 2,500–AUD 5,000 per arch; at Picasso Dental Clinic in Vietnam they cost AUD 452–566. All-on-4 is a fixed, permanent arch supported by four implants. Australian private All-on-4 costs AUD 28,000–AUD 45,000 per arch; at Picasso it costs AUD 7,068–AUD 12,436. The right choice depends on your budget, bone volume, and whether you need fixed or removable teeth.

Comparison at a glance

Factor	Full dentures	All-on-4
Fixed or removable	Removable	Fixed
Bone preservation	No — bone resorbs	Yes — implants preserve bone
Bite force	Reduced (20–30% of natural)	Near-natural
Stability during eating	Variable (lower arch often moves)	Stable
Feels like natural teeth	No	Yes
Surgery required	No (unless extractions)	Yes
Immediate result	Yes	Provisional same day; final in 3–6 months
Maintenance	Remove and clean daily	Brush in situ; same as natural teeth
Lifespan	5–10 years before relining/replacement	15–25+ years
Upfront cost	Lower	Higher

When dentures make clinical sense

Patient is medically unsuitable for implant surgery (significant cardiac risk, anticoagulants, poorly controlled diabetes)
Bone volume is severely insufficient and patient declines grafting
Budget is the overriding constraint
Patient is elderly with limited life expectancy that reduces the long-term benefit of implants
Patient prefers a reversible, non-surgical option

When All-on-4 makes clinical sense

Patient has adequate bone (or can have grafting)
Patient is in good general health for surgery
Patient wants fixed, stable teeth
Patient plans to use the restoration for 15+ years
Budget allows the upfront investment

The implant-retained overdenture — the middle path

Two implants placed in the lower jaw cost AUD 4,246 at Picasso. The existing lower denture clips onto these implants — it is still removable, but it no longer moves during eating. This is the most practical solution for patients who:

Experience lower denture instability (the most common denture complaint)
Cannot or will not commit to full All-on-4
Want a significant quality-of-life improvement at lower cost than full arch
