All-on-6 — Full-Arch Fixed Restorations with 6 Implants
A high-stability clinical restoration placing 6 implants to optimize chewing load distribution. Recommended for larger arches or softer bone densities, bypassing extensive bone grafting.
1. What is All-on-6, and When is it Indicated Over All-on-4?
All-on-6 is a full-arch restoration technique that replaces an entire arch of missing teeth using 6 implants, instead of 4 implants like All-on-4. The addition of two extra implant posts ensures uniform chewing force distribution, improves mechanical stability, and reduces the stress placed on individual fixtures.
All-on-6 is not a mandatory upgrade to All-on-4. It is a distinct clinical indication tailored to your jawbone density and bite force – inserting more implants does not automatically mean safety or success. Our surgeons arrange the 6 posts strategically to anchor onto your natural dense bone.
Key Benefits of All-on-6
- Distributes bite forces evenly across larger jaw arches
- Rigid screw-retained fixation with high load tolerance
- Restores natural smile support and facial fullness
- Immediate load temporary bridge fitted within 24 hours
- Straightforward hygiene using dental water flossers
2. 3D CBCT Determines the Need for 4 or 6 Implants
The selection between All-on-4 and All-on-6 is strictly based on diagnostic data from a 3D Cone Beam CT (CBCT) scan, rather than patient preference or budget. The CBCT scan evaluates:
- Bone volume and structural density at each planned implant site.
- Anticipated bite forces (typically higher in younger males or patients with bruxism).
- Overall jaw size (larger arches require wider support spans to prevent prosthetic flexion).
- Resorption patterns and the viability of avoiding bone grafts by utilizing alternative sites.
DENTALNKT PROTOCOL
We do not recommend the number of implants prior to evaluating a 3D CBCT scan. We do not support the idea that '6 implants are always better than 4'. If an All-on-4 is clinically sufficient, adding extra posts only increases surgical invasiveness and cost without added benefit.
3. Am I a Good Candidate for All-on-6?
Who is this suitable for?
- Complete tooth loss on one or both arches, with bone available outside the 4 strategic sites.
- Patients with high chewing loads or active lifestyles.
- Larger dental arches requiring intermediate mechanical support.
- Moderate bone density where distributing the load over more posts improves safety.
Who needs close assessment?
- Severe bone resorption across the entire arch (may require bone grafts or Zygomatic implants).
- Uncontrolled diabetes, active osteoporosis, or recent head/neck radiation.
- Heavy smoking habits (must quit 2 weeks before and after surgery).
- Severe bruxism (requires a night guard to protect final restorations).
4. All-on-6 Comparison Index
| Criteria | All-on-6 | All-on-4 | Single Implants | Removable Dentures |
|---|---|---|---|---|
| Implants per arch | 6 | 4 | 1 post per lost tooth (10-12) | None |
| Bite force distribution | More uniform, more support points | Concentrated at 4 strategic sites | Localized to each tooth position | Unbalanced, rests on soft tissues |
| Bone grafting requirement | Rarely required due to more placement options | Usually not required | High if bone is resorbed | None |
| Ideal scenario | Distributed bone, high bite load, large arch | Good bone at the 4 targeted sites | Single or multiple missing teeth | Tight budget, surgery avoiders |
| Surgical invasiveness | Higher than All-on-4 (2 more posts) | Lower than All-on-6 | Highest if placing individual fixtures | Non-surgical |
| Fixation type | Fixed (Screw-retained) | Fixed (Screw-retained) | Fixed (Cement/Screw-retained) | Removable |
* Clinical Note: The decision to place 4 or 6 implants is a clinical diagnosis based on bone density and load calculations, not a package preference.
5. Risks & Complications to Know Before Surgery
- Due to placing 6 implants instead of 4, surgical time is longer and postoperative swelling may be slightly increased.
- Osseointegration rate is high (~98%) but minor risks of individual implant rejection exist due to biology or infection.
- The immediate load temporary bridge is structural but delicate – strictly no hard chewing is allowed during healing.
- Maintaining oral hygiene around 6 implants is more demanding than All-on-4, requiring careful flossing to prevent peri-implantitis.
- Immediate loading capability depends entirely on primary implant stability measured intra-operatively during surgery.
- Prosthetic frameworks and crown materials experience natural wear over time and require periodic maintenance.
6. Step-by-Step Treatment Timeline — 2 Trips Required
| Treatment Stage | Clinical Procedure | Recommended Stay |
|---|---|---|
| Trip 1 (Implant Placement) | Clinical exam, 3D CBCT scan, extraction of failing teeth, implant surgery for 6 fixtures, immediate load of acrylic temporary bridge (if stable), suture removal and clinical follow-ups. | 8 – 12 Days in Hanoi |
| Osseointegration Period | Implants biologically integrate with the jawbone while you are at home in Australia. Patient functions normally with temporary teeth (soft-diet focus). | 3 – 6 Months (in Australia) |
| Trip 2 (Final Restoration) | X-ray integration check for all 6 implants, digital impressions, structural framework try-in, custom porcelain teeth setup, final screw-retained bridge delivery, warranty cards handover. | 5 – 7 Days in Hanoi |
Flight Booking Tip: Trip 1 for All-on-6 requires a stay of 8-12 days. We recommend booking flights with a 2 to 3-day buffer window after the surgery and temporary fitting. This allows final evaluations before flying.
7. Documentation Handed Over after Trip 1
- Implant Passport specifying brands, models, and batch/lot numbers for all 6 fixtures.
- Post-surgical X-ray film showing correct placement alignment.
- Home-care guide booklet and 24/7 direct patient coordinator hotline.
Documentation Handed Over after Trip 2
- Official Warranty Certificate for both 6 implants and prosthesis structure.
- Lab certification for materials used in framework and porcelain teeth.
- Detailed electronic medical record using ADA standard procedure codes.
8. Post-Op Care Guidelines in Australia
- 1Eat soft, cut-up foods for the first 3-6 months. Avoid directly biting into hard food to prevent temporary bridge fractures.
- 2Quit smoking completely – nicotine constricts blood vessels, slows healing, and is the leading cause of early implant failures.
- 3Maintain strict hygiene with soft-bristled brushes, water flossers on low pressure, and warm saline rinses after meals.
- 4We recommend visiting your local Australian dentist for a routine progress check after 6-8 weeks.
