All-on-4 types can be confusing if you’re looking for a full tooth replacement solution.
If you’re having trouble understanding the differences between all the All-on-4 options and which one is best for you, then you’re not alone.
What are the types of All-on-4 dental implants?
All-on-4 dental implants offer various types to suit different patient needs: traditional, hybrid, mini, immediate load, and angled implants. Each type has unique benefits, with success rates ranging from 94.8% to 96.5%. Traditional implants provide high success rates and aesthetic appeal, while mini-implants offer reduced healing time. The choice depends on factors like bone density and aesthetic goals.
| Implant Type | Description | Key Benefits |
|---|---|---|
| Traditional All-on-4 Implants | Standard implants placed in the jawbone to support a full arch of teeth. | High success rates, aesthetic benefits, and durable foundation for a full arch of teeth. |
| Hybrid All-on-4 Implants | Combining fixed and removable dentures attached to four implants for enhanced stability and aesthetics. | Enhanced stability, aesthetic benefits, and flexibility in denture design. |
| Mini-Implants for All-on-4 | Smaller implants that require less healing time and offer increased stability and longevity. | Reduced healing time, increased stability, and suitability for patients with limited bone density. |
| Immediate Load All-on-4 Implants | Allowing for immediate loading of temporary teeth, reducing healing time and enhancing patient satisfaction. | Immediate aesthetic benefits, reduced healing time, and high success rates (94.8%). |
| Angled / Tilted All-on-4 Implants | Placed at an angle to maximize bone use and minimize surgical procedures. | Maximized bone use, minimized surgical procedures, and suitability for patients with limited bone density. |
All-on-4 | Immediate (Same Day) vs Delayed Load
When considering All-on-4 dental implants, one of the biggest decisions is whether to go for immediate load or delayed load implants.
This decision can impact the healing process and the overall success of the treatment.
Immediate Load All-on-4 (Same Day)
Immediate load All-on-4 allows for immediate loading of temporary teeth, less healing time and more patient satisfaction.
This has been shown to have high success rates; a 7-year clinical and 5-year radiographic retrospective case series showed a 94.8% implant survival rate (1).
Immediate load also has aesthetic benefits; patients can have a full set of teeth from day one.
Delayed Load All-on-4
Delayed load All-on-4 involves a healing period before the final prosthesis is placed.
This is suitable for patients with certain health conditions or those who need bone grafting.
A study on the NobelGuide All-on-4 treatment concept showed a 96.5% implant survival rate over the medium to long term (3).
| Implant Type | Healing Time | Success Rate | Aesthetic Benefits |
|---|---|---|---|
| Immediate Load | 1-2 days | 94.8% | High |
| Delayed Load | Several months | 96.5% | Moderate |
All-on-4 Single Arch Vs. Full Mouth
Deciding between single arch and full mouth All-on-4 implants is a big decision that depends on many factors, including the patient’s dental needs, bone density and aesthetic preferences.
All-on-4 for Upper Arch
All-on-4 for upper arch is designed to provide a stable and aesthetic solution for patients who have lost all their upper teeth.
A study on the NobelGuide All-on-4 treatment concept showed 98.5% implant survival rate for upper arch implants over medium to long term (3).
This high success rate is due to the precise planning and execution of the treatment, which minimizes the risk of complications.
All-on-4 for Lower Arch
All-on-4 for lower arch is designed to address the specific challenges of lower jaw rehabilitation.
Angled implants can be particularly useful in this situation as it allow for more bone use and less surgery.
A review article on the All-On-Four treatment concept emphasized the importance of proper patient selection and precise surgical technique for lower arch implants (4).
Full Mouth All-on-4
Full mouth All-on-4 is a full solution for patients who have lost all their teeth.
This involves placing implants in both the upper and lower jaws to support a full set of teeth that closely mimic the look and function of natural teeth.
A 7-year clinical and 5-year radiographic retrospective case series showed 94.8% implant survival rate for full mouth All-on-4 (1).
Single Arch All-on-4 to Replace Missing Teeth
Single-arch All-on-4 is suitable for patients who have lost all their teeth in one jaw.
This is less invasive and more cost-effective than full-mouth implants.
A study on the use of narrow platform NobelActive implants for single-arch All-on-4 showed a 96.2% implant survival rate (2).
Traditional vs Angled All-on-4
Deciding between traditional implants and angled All-on-4 is a big decision that depends on many factors, including the patient’s bone density, dental needs and aesthetic preferences.
Traditional Dental Implants All-on-4
Traditional All-on-4 is placed in the jawbone to support a full arch of teeth.
This has a high success rate; a study on the use of narrow platform NobelActive implants showed a 96.2% implant survival rate over the medium to long term (2).
Traditional technique also has aesthetic benefits as it allows for a more natural-looking smile.
Angled / Tilted All-on-4
Angled / tilted All-on-4 is placed at an angle to maximize bone use and minimize surgery.
This is suitable for patients with limited bone density.
A review article on the All-On-Four treatment concept emphasized the importance of proper patient selection and precise surgical technique for angled implants (4).
Angled implants can also reduce the need for bone grafting, making the treatment more efficient and less invasive.
All-on-4 Implants by Size
All-on-4 implants come in various sizes to fit different patient needs.
Understanding the difference between standard and mini implants will help patients make informed decision for their treatment.
Standard Implants
Standard All-on-4 implants is the most common type and suitable for most patients.
It is designed to provide a stable and strong foundation for a full arch of teeth.
A study on the use of narrow platform NobelActive implants emphasized the importance of precise implant placement for optimal results (2).
Standard implants require a healing period before the final prosthesis is placed to ensure a strong bond between the implant and surrounding bone.
Mini Implants
Mini All-on-4 implants is smaller in diameter and used for patients with limited bone density or those who want a less invasive procedure.
They have several advantages, including reduced healing time and increased stability.
they A review article on the All-On-Four treatment concept mentioned that mini implants is ideal for patients with narrow jawbones as it allow for more precise placement and minimize complications (4).
Mini implants also provide a more aesthetic solution as it can be placed in areas where standard implants can’t.
| Implant Type | Implant Size | Healing Time | Success Rate | Aesthetic Benefits |
|---|---|---|---|---|
| Standard All-on-4 Implants | Standard diameter | Several months | 96.2%[2] | High |
| Mini All-on-4 Implants | Smaller diameter | Reduced healing time | Not specified in the references | Increased stability and aesthetic benefits |
Conclusion & Key- Takeaways
Key Takeaways:
All-on-4 implants has various solutions for full tooth replacement: traditional, hybrid, mini, immediate load and angled implants.
Immediate load or delayed load depends on patient needs and bone density.
Single arch and full mouth implants for different patient needs; full mouth implants are a comprehensive solution.
Traditional and angled implants have different benefits; angled implants maximize bone use and minimize surgery.
