All-on-4 vs DenturesWhich Is Better for You?
All-on-4 dental implants and conventional dentures both replace missing teeth - but they are fundamentally different in performance, comfort, longevity, and impact on oral health. All-on-4 is a fixed, durable, long-term solution that preserves jawbone. Dentures are removable, accelerate bone loss, and require replacement every 5-10 years.
Head-to-Head Comparison
| Feature | All-on-4 Implants | Conventional Dentures |
|---|---|---|
| Attachment | Fixed (screwed to implants) | Removable (sits on gums) |
| Chewing efficiency | 85-95% of natural teeth | 10-20% of natural teeth |
| Jawbone preservation | ✅ Yes (stimulates bone) | ❌ No (accelerates bone loss) |
| Adjacent tooth damage | None | N/A (no remaining teeth) |
| Stability | Excellent (cannot move) | Poor (slips, rocks, lifts) |
| Adhesive needed | No | Often yes |
| Speech impact | None | Lisp, whistling, slurring |
| Taste impact | None | Palate coverage reduces taste |
| Lifespan | 20+ years (implant); 15-25 years (prosthesis) | 5-10 years |
| Maintenance | Annual check-up + daily brushing | Daily removal, soaking, relines every 2 years |
| Confidence | High | Low (fear of slipping) |
| Cost (AU) | $38,000-$44,000 per arch | $2,900-$4,400 per arch |
| Cost (Stunning Dentistry) | from $3,850 per arch | Not offered (implants preferred) |

The Bone Loss Problem
This is the most important difference: dentures accelerate jawbone resorption. Without tooth roots (or implants) stimulating the bone, the jaw shrinks progressively. After 10-20 years of denture wear:
- The lower jaw can lose 60% of its height
- Dentures become increasingly ill-fitting
- Facial appearance changes dramatically ("sunken face")
- Eventually, there may not be enough bone to support any prosthesis
Dental implants prevent this. They stimulate the bone just like natural tooth roots, maintaining jaw volume and facial structure.
