All-on-4 or All-on-6: Which is better?

All-on-4 or 6-dental implants provide a perfect solution for those with missing teeth. However, most people are not sure which dental implants they should get. It can be really hard to decide if all-on-4 or 6: Which is better?

Keep reading to find out the difference between an All-on-4 and All-on-6 implant and, among the two, whether all-on 4 or 6 is better. 

All-On-4 and All-On-6: Methods of Full Mouth Dental Implants 

All-On-4 Dental Implants: 

The All-On-4 dental implant technique involves using four implants to replace an entire set of upper or lower teeth. These four implants provide support for a new set of fixed teeth.

Implant Placement: 

 In the All-On-4 method, four implants are placed in each arch without the need for bone grafting. Two implants are placed vertically at the front of the mouth, while the other two are placed at an angle towards the back of the mouth.

Hybrid Denture: 

This approach uses a hybrid denture attached to rods, which allows the replacement of the upper or lower teeth with just four implants.


All On 4 implants are an effective solution for those with severely damaged teeth. This method avoids the need to replace each tooth individually and simplifies the process.

All-On-6 Dental Implants: 

The All On 6 dental implant method uses six implants to support a dental bridge that replaces teeth in the upper or lower jaw.

Implant Placement: 

The six implants provide a secure base for the bridge, which holds the artificial teeth in place permanently.

Bone Grafting: 

Unlike the All-On-4 method, bone grafting may be necessary for All-On-6 implants to ensure adequate support.


All-On-6 implants can be beneficial for individuals who have had long-term issues with smiling, chewing, or eating. The additional implants offer enhanced stability and support for the dental bridge.

Both All On 4 and All On 6 methods are innovative solutions for full-mouth dental restoration and offer patients a fixed, reliable, and aesthetically pleasing set of teeth.

All on 4 or 6 Dental Implant: A comprehensive Comparison 

Feature All-On-4 Implants All-On-6 Implants
Number of Implants 4 per arch 6 per arch
Placement 2 implants vertically at the front, 2 implants angled at the back 6 implants spread evenly across the arch
Bone Grafting Typically not required It may be required to ensure adequate support
Support Structure Supports a hybrid denture Supports a bridge
Stability Provides good stability for most patients Offers enhanced stability due to more implants
Procedure Complexity Less complex due to fewer implants More complex due to additional implants
Recovery Time Shorter initial recovery period Slightly longer initial recovery period
Best For Patients with less bone density Patients needing extra stability or with sufficient bone density
Cost Generally less expensive Typically more expensive due to more implants
Longevity and Durability Very durable and long-lasting Very durable and long-lasting
Suitability Suitable for patients with significant tooth loss and minimal bone loss Suitable for patients with severe tooth loss and need for additional stability

All-On-4 and All-On-6 Method for Prostheses 

Both the All-On-4 and All-On-6 methods offer various prosthesis options to restore dental function and appearance.

Hybrid Implant 

A hybrid implant is a type of prosthesis that is secured by dental implants. The process begins with the surgeon inserting implants into the maxillary bone. These implants are then connected to a prosthetic framework, which is bonded to prosthetic teeth to restore both function and appearance. This type of prosthesis cannot be removed by the patient because it is screwed onto abutments. Abutments are components that connect the prosthesis to the dental implants embedded in the bone.


  • Improved Phonetics and Aesthetics: It feels and looks like natural teeth.
  • Stable Chewing and Facial Muscles: The restoration helps maintain the stability of chewing muscles and facial expressions.
  • Bone Health: It helps preserve bone tissue, preventing bone loss after tooth extraction.
  • Longevity: With proper care, a hybrid prosthesis can last many years, providing comfort and functionality.

Hybrid prostheses are ideal for individuals who have lost all their teeth and have significant bone loss. It offers a non-removable solution that closely mimics natural teeth in both appearance and function.

Hybridge Bridge vs All On 4

The Hybridge bridge prosthesis is designed to replace all the teeth in the upper jaw, lower jaw, or both, using a minimal number of implants. Instead of needing an individual implant for each tooth, a few strategically placed implants support a full bridge of new teeth, simplifying the process significantly. Any remaining upper teeth must be removed before installing a Hybridge prosthesis. Implants can be placed immediately, with the prosthesis following shortly after.

A Hybridge implant bridge consists of a titanium screw that is inserted into the jawbone, and an abutment connects the screw to the crown that serves as the replacement tooth. This type of bridge is supported by 4 to 6 dental implants anchored in the gums and jaw, providing a permanent solution that doesn’t shift while eating or chewing. Unlike traditional dentures, the Hybridge bridge is fixed in place and cannot be removed by the patient, which can make cleaning more challenging. However, it offers stability and comfort that traditional dentures cannot match.


The choice between all on 4 or 6 implants depends on your specific dental needs, bone density, and long-term goals. Both options offer effective solutions for restoring full arches of teeth, providing improved aesthetics, functionality, and quality of life. All-on-4 may be suitable for those with less bone density or who prefer a less invasive procedure, while All-on-6 can offer enhanced stability and support for patients with sufficient bone structure. It is better to consult with a dental professional to know what is best for you.

What is the main difference between All on 4 or 6 implants? 

The main difference lies in the number of implants used: All-on-4 utilizes four implants per arch, while All-on-6 uses six. All-on-6 provides extra stability and support, making it ideal for patients with adequate bone density.

Is the recovery time different for All-on-4 and All-on-6 implants? 

The recovery time for both procedures is similar, with initial healing taking about 6-8 weeks. However, individual recovery experiences vary based on factors such as overall health and following post-operative care instructions.

Which option is more cost-effective, All on 4 or 6? 

All on 4 is more cost-effective due to the fewer number of implants. However, All on 6 provides better long-term stability, reducing the need for future adjustments or replacements.
