There are benefits, limitations, and long-term considerations to weigh and depending on your individual needs, alternatives like All-on-6 dental implants might offer even better outcomes.
In this complete guide, we’ll give you a clear, honest look at your options for Full mouth dental implants, empowering you to choose the best path for your health, your confidence, and your future.
Because you deserve a smile that doesn’t just look good, it feels like home.
What is a All on 4 technique
The All-on-4 technique is a dental implant procedure designed to replace complete set of fixed teeth on 4 Implants using only four implants in each jaw, instead of placing an implant for every missing tooth.
Here’s how the All-on-4 technique works:
Strategic Implant Placement:
Two implants are placed vertically at the front of the jaw (where bone is usually stronger).
Two implants are placed at an angle (about 30°–45°) toward the back of the mouth to maximize support and avoid sinus cavities (upper jaw) or nerve canals (lower jaw).
Immediate Loading Implants: A temporary set of teeth (bridge) is often attached to the implants on the same day or within 24–48 hours.
After healing (about 3–6 months), the final, permanent teeth are made and attached.
Angled Implant Concept:
By tilting the back implants, the All-on-4 technique avoids the need for bone grafting, even in patients with some bone loss.
It uses the available native bone more efficiently.
Advantages of All-on-4 Dental Implants
Faster Treatment Time: Immediate loading is possible, meaning you can get a temporary set of teeth the same day can also be called as Teeth in a day Implants.
- Avoidance of Bone Grafts: Often eliminates the need for complex and costly bone grafting.
- Cost-Effective: Fewer implants mean reduced overall cost compared to individual implant placement.
- Aesthetic Improvement: Restores facial profile, preventing sunken cheeks and premature aging.
- Simplified Maintenance: Easy to clean compared to removable dentures.
- Boosts Confidence: Strong, functional teeth improve speech, chewing ability, and self-esteem.
Major Disadvantages of All-on-4 Dental Implants
Higher Risk If One Implant Fails
The All-on-4 system depends entirely on four implants supporting the full arch. If even one implant fails especially during the early healing phase-the entire prosthesis can be compromised. This often necessitates full removal and replacement of the prosthesis.
Limited Bone Support and Force Distribution
With only four implants, the surface area for distributing chewing forces is significantly reduced. This makes the prosthesis more vulnerable to functional overload, particularly in patients with high bite forces or habits like bruxism.
Not Suitable for Severe Bone Loss
In cases of advanced bone resorption, especially in the posterior maxilla or mandible, the angled placement of implants may still be insufficient. Additional procedures like bone grafting or the use of zygomatic or pterygoid implants may become necessary.
Permanent Prosthesis Is Delayed
Contrary to popular belief, All-on-4 does not offer immediate permanent teeth. Only a temporary prosthesis is delivered initially. The final, permanent prosthesis is typically provided after 4 to 6 months, once full osseointegration occurs.
Prosthetic Design Has Limited Flexibility
Any future complications such as implant failure, bone changes, or gum issues can be difficult to manage with an All-on-4 setup. The prosthesis often needs to be completely redesigned, as minor adjustments are not feasible.
Reduced Long-Term Durability
While All-on-4 offers good results for up to 8 to 10 years, protocols with six or more implants (like All-on-6) provide better load distribution, reducing the chances of screw loosening, prosthetic fractures, or implant fatigue over time.
Occlusal Overload
Four implants must absorb all occlusal forces, increasing the risk of overload. This is especially concerning in patients with heavy chewing patterns or unbalanced bites, and it may lead to mechanical failures or bone loss around implants.
Cantilevers Cannot Be Avoided
Because the implants do not extend to the posterior end of the jaw, cantilevers are inevitable. These extensions increase bio mechanical stress, particularly during chewing, and may reduce prosthetic longevity.
Lack of Implant Support for Posterior Teeth (Molars)
The molars, which handle most of the grinding forces, are not directly supported by implants in an All-on-4 system. This compromises mastication efficiency and increases the risk of implant complications over time.
All-on-4 vs All-on-6 Dental Implants: A Detailed Comparison Table
| Feature | All-on-4 | All-on-6 |
|---|---|---|
| Number of Implants per Arch | 4 implants | 6 implants |
| Force Distribution | Limited, higher stress on each implant | Better, forces are more evenly distributed |
| Suitability for Severe Bone Loss | Not very ideal, may require additional grafting or zygomatic implants | More versatile, often avoids need for grafting |
| Support for Posterior Teeth | Limited, molars often lack direct implant support | Improved, posterior implants provide direct support for molars |
| Cantilever Presence | Inevitable, due to lack of implants in the posterior segment of the jaw | Eliminated, with implants placed further back |
| Risk if One Implant Fails | High risk; failure may lead to prosthesis revision | Lower risk; remaining implants often maintain stability |
| Prosthetic Stability | Moderate, more prone to mechanical issues | Higher, reduced risk of screw loosening or fractures |
| Longevity & Durability | 8 to 10 years typical with good maintenance | Often exceeds 15 to 20 years with proper care |
| Ideal for Strong Bite/Bruxism? | Not ideal, higher risk of overload | Better, can manage higher functional loads |
| Flexibility for Future Modifications or Upgrades | Limited, changes often require complete redesign | Easier to modify |
| Initial Cost | Lower upfront | Slightly higher, but more cost-effective long term |
| Permanent Prosthesis Timing | Usually after 4–6 months (initial temporary provided) | Immediate |
| Clinical Recommendation | Suitable for select patients with adequate bone and controlled bite forces | Preferred for any kind of bone condition |
Advantages of All on 6 dental implants Over All-on-4
- Better Load Distribution: Six implants spread chewing forces more evenly, reducing stress on each implant.
- Higher Stability: Provides superior support for the prosthesis.
- Reduced Risk of Failure: The extra implants offer a safety net; failure of one does not necessarily compromise the entire arch.
- Ideal for Severe Bone Loss: More implants can engage available bone better.
- Long-Term Success: Studies show All-on-6 offers a longer lifespan and fewer complications.
- Stronger Prosthesis: More implant anchors mean greater structural integrity for the bridge.

FAQs About All-on-4 Dental Implants
All-on-4 dental implants use four strategically placed implants to support a full arch of prosthetic teeth, providing a stable and aesthetic replacement for natural teeth.
Traditional implants may require one implant per tooth and bone grafting; All-on-4 requires only four implants, often without grafts.
Patients with moderate bone loss, good general health, and no active gum disease are ideal candidates.
Surgery takes about 2- 4 hours per, and a temporary prosthesis can often be placed the same day.
Usually not, as the technique utilizes available bone with angled implants.
Mild to moderate discomfort is expected post-surgery, managed with prescribed medications.
Success rates range between 94% and 98% over 10 years.
With proper care, they can last 8 to 10 years or more.
Yes, if diabetes is well controlled. All on 6 using CPBCCI Protocol is a safer alternative for diabetics where the cortical bone is engaged to place the implants providing instant stability and immediate prosthesis.
Common materials include acrylic, zirconia, and titanium frameworks.
Costs vary, generally ranging from $30,000 to $40,000 depending on location and materials. All on 6 using CPBCCI Protocol costs 70% lesser than what it costs for All on 4 in US,UK and Australia using the same FDA approved Conventional implants and Zirconia teeth on Titanium framework.
Typically not fully, but some insurance plans may cover portions related to medical necessity.
Smokers have a higher risk of implant failure but can still be candidates with smoking cessation. All on 6 using CPBCCI Protocol is safe implants for diabetics and smokers as the cortical bone is engaged providing immediate stability and fixed permanent teeth in less than a week.
All-on-4 implants are generally safe, but like any surgical procedure, they carry some risks:
- Implant failure, often due to poor bone integration or excessive force.
- Bone loss, particularly in cases where tilted implants are used in areas with limited bone.
- Prosthetic complications, such as fracture, wear, or loosening of the denture.
- Compared to All-on-6 implants, All-on-4 may have a slightly higher risk of long-term complications in patients with severe bone loss, since it uses fewer implants for full arch support. All-on-6 (graft less dental implants) often provide greater stability and bone engagement.
Soft foods like smoothies, scrambled eggs, and yogurt for the first one week after surgery.
Daily brushing, flossing under the bridge with water flossers, and regular dental cleanings are vital.
Every 8 to 10 months for professional maintenance.
Yes, prosthetic parts can often be repaired or replaced.
A failed implant might require revision surgery or replacement depending on the severity.
Yes, including All-on-6, All-on-8, and implant-supported dentures.
All-on-6 uses six implants offering better support and long-term durability.
All-on-6 generally offers greater support for upper jaw restorations.
Liquid diet immediately post-op, progressing to soft foods after a few days.
Yes, most patients undergo the procedure under local anesthesia and few opt for sedation for comfort during the procedure.
