If you are missing most or all of your teeth, or struggling with loose, uncomfortable dentures that shift every time you eat or speak, modern dentistry offers a permanent, transformative solution: Full-Arch Fixed Implant Bridges.
Instead of replacing every single tooth with an individual implant (which would require 14 to 16 separate titanium posts per jaw), advanced biomechanical protocols allow us to anchor a complete, permanent bridge of 12 to 14 teeth onto just four (All-on-4) or six (All-on-6) strategically positioned implants.
As an MDS Periodontist and Implantologist at Dental Planet Mysore, one of the most frequent questions patients ask during our digital 3D CBCT consultations is: "Doctor, should I choose All-on-4 or All-on-6?" Below is the complete clinical comparison to help you make an informed decision.
1. Understanding the Biomechanical Difference
The All-on-4 Concept
Pioneered by Nobel Biocare, this technique places 2 vertical implants in the front jaw and 2 posterior implants angled at up to 45 degrees.
- Angled Posterior Implants: Avoids maxillary sinus and mandibular nerve canals.
- Bone Graft Avoidance: Maximizes existing anterior dense bone without grafting.
- Cost-Effective: Fewer implant fixtures lower surgical costs.
The All-on-6 Concept
Distributes chewing forces across 6 implant anchors throughout the dental arch, creating an exceptionally rigid foundation.
- Enhanced Force Distribution: Redundant load support for heavy biters or bruxism.
- Greater Prosthetic Longevity: Lower stress concentration per titanium fixture.
- Requires Adequate Bone: Needs healthy bone volume in molar zones.
2. Comprehensive Clinical Head-to-Head Comparison
| Feature | All-on-4 Implants | All-on-6 Implants |
|---|---|---|
| Number of Implants | 4 per arch (2 axial, 2 tilted) | 6 per arch (typically axial/parallel) |
| Bone Density Requirement | Moderate to Low (Bone grafting rarely needed) | Moderate to High (Bone grafting may be required) |
| Bite Force Capacity | Excellent for normal everyday chewing | Maximum stability (best for clenchers/grinders) |
| Immediate Loading (Teeth in a Day) | Yes (within 24-48 hrs) | Yes (within 24-48 hrs) |
| Prosthesis Options | Hybrid Acrylic or Zirconia | CAD/CAM Monolithic Zirconia or PFM |
| Starting Cost in Mysore | From ₹3,50,000 / arch | From ₹4,80,000 / arch |
3. Which System Is Right for Your Specific Case?
Choose All-on-4 If:
- You have experienced significant jawbone shrinkage: If you have been toothless or wearing dentures for years, the bone in your molar areas has likely resorbed. All-on-4 bypasses the sinuses and nerve canals without requiring costly, time-consuming bone grafting.
- You want minimal surgical invasiveness: 4 implants mean fewer surgical sites, shorter chairside time, and accelerated postoperative healing.
- You desire the most cost-effective full-arch rehabilitation: Reduces total expenditure on titanium fixtures and abutments.
Choose All-on-6 If:
- You have adequate bone height and width: Confirmed on 3D CBCT imaging.
- You have a strong jaw or clench your teeth (bruxism): The 2 additional implants provide an extra safety net against excessive mechanical stress.
- You are restoring the upper jaw with softer bone density: The maxilla naturally has softer, more cancellous bone than the dense mandible, making 6 fixtures highly advantageous for long-term load bearing.
4. Digital Precision at Dental Planet Mysore
At Dental Planet, full mouth rehabilitation is strictly planned through Digital Guided Implantology:
3D CBCT Volumetric Diagnostics
Sub-millimeter 3D mapping of bone density, nerve pathways, and sinus anatomy eliminates surgical guesswork.
Computer-Guided Surgical Stents
Custom 3D-printed guides ensure each titanium post is inserted at the exact planned angulation and depth.
CAD/CAM Monolithic Zirconia Prosthetics
Milled from solid diamond-hard zirconia blocks that will never chip, stain, or wear down like conventional plastic dentures.
5. Frequently Asked Questions
Is the procedure painful?
No. The entire procedure is performed under deep local anesthesia and conscious sedation if desired. Patients typically report feeling far less discomfort than having teeth extracted, and mild soreness is easily managed with routine pain relief for 2 to 3 days.
How long do All-on-4 and All-on-6 implants last?
Titanium implants fuse permanently with your jawbone in a biological process called osseointegration. With proper hygiene and regular 6-month check-ups at Dental Planet, implants have a documented clinical lifespan of 25+ years to a lifetime.
Are there EMI options available in Mysore?
Yes! Dental Planet Mysore provides flexible 0% interest EMI payment plans for full-mouth implant procedures through leading healthcare finance partners.
