Dental implant techniques, specifically All on 4 and All on 6, can sometimes leave patients befuddled. Both these paradigms have carved niches in restorative dentistry, but understanding their nuances is essential. In this guide, we’ll demystify these systems, ensuring you’re well-equipped to make informed dental decisions.


Venturing into the realm of dental health can occasionally feel overwhelming. Still, the emergence of implant techniques like All on 4 and All on 6 has illuminated pathways for many in their quest for optimal dental functionality and aesthetics. Beyond the technical jargon and dentist speak, these methodologies present tangible solutions for genuine dental challenges.

With the aim to provide clarity, this article sheds light on the intricacies of All on 4 vs All on 6 dental implants, offering readers an in-depth understanding to guide their dental journey.

What are All on 4 and All on 6 Dental Implants?

Dental implants have transformed smiles across the globe, providing durable, functional, and aesthetic tooth replacement solutions. Within this field, two prominent systems have emerged: All on 4 and All on 6. Yet, to many, these terms may sound more like mathematical jargon than dental solutions. Let’s unpack what they truly entail.

All on 4 Dental Implants

The “All on 4” concept is innovative in its simplicity. Here’s how it works:

  • Foundational Theory: Four dental implants are surgically placed within the jawbone. These serve as the foundational pillars for a full dental bridge or denture.
  • Placement: Two implants are positioned at the front of the mouth, and two are angled in the back, maximising the use of existing bone and often negating the need for bone grafts.
  • Advantages: Immediate results are often feasible, with temporary prostheses placed on the same day of surgery. The strategic positioning also leverages natural bone structure, often reducing the need for invasive procedures.

All on 6 Dental Implants

A close sibling to the “All on 4” system, the “All on 6” system provides an alternative approach:

  • Foundational Theory: As the name suggests, six dental implants are utilised as the structural underpinning for a full dental bridge or over-denture.
  • Placement: Implants are distributed more evenly across the jaw, often offering a broader base of support. This can be especially beneficial for individuals with more extensive bone loss.
  • Advantages: Due to the additional implants, “All on 6” can provide increased stability and strength, potentially accommodating a broader range of dental scenarios.

Both systems offer state-of-the-art solutions for full arch tooth replacement. However, the choice between All on 4 and All on 6 hinges on individual needs, oral health conditions, and specific dental goals.

Key Differences Between All on 4 Vs All on 6 Dental Implants

While both All on 4 and All on 6 dental implants share the foundational purpose of restoring an entire arch of teeth on a minimal number of implants, their distinctions are pivotal in determining the right choice for individual patients. Here’s a comprehensive breakdown of their key differences:

1. Number of Implants and Their Distribution

  • All on 4:
    • Uses four implants.
    • Two are typically placed vertically in the front of the mouth, while the other two are angled at the back. This configuration optimises the use of available bone.
  • All on 6:
    • Employs six implants.
    • These are evenly distributed, often providing a broader base of support and accommodating a wider range of dental anatomies.

2. Duration and Complexity of the Procedure

  • All on 4:
    • Due to fewer implants, the surgical procedure can be slightly quicker.
    • Immediate load implants (temporary prostheses) are often placed on the same day.
  • All on 6:
    • With additional implants, the procedure might take longer and might require more planning.
    • The added complexity can potentially provide more stability in the long run.

3. Bone Volume and Quality Requirements

  • All on 4:
    • Specifically designed for patients with lower bone density or volume.
    • The angled back implants utilise existing bone, often avoiding the need for bone grafts.
  • All on 6:
    • Typically requires a better quality and volume of bone due to the placement of more implants.
    • Might be more suitable for patients with extensive bone loss as it offers a more expansive distribution.

The journey of choosing between All on 4 and All on 6 dental implants isn’t merely about counting the implants but understanding the strategic differences in their application. While both methods aim to restore functionality and aesthetics, the nuances in their design and application can have significant implications for individual dental needs.

  • Cost-Effective: Typically less expensive due to fewer implants and potentially no bone grafting.
  • High Success Rate: The technique boasts a high success rate, especially in the lower jaw.


  • Limited Redundancy: If one implant fails, it can be a significant issue, given there are only four supporting the arch.
  • Potential for Overloading: There’s a potential risk of overloading the implants since there are fewer of them.
  • Not Always Suitable: Might not be the best option for those with significant bone loss in the front of the jaw.

All on 6 Dental Implants


  • Increased Stability: With more implants distributing the force, there’s often greater stability, especially for the upper jaw.
  • Flexibility in Design: Allows for more flexibility in prosthetic design due to additional implants.
  • Better Distribution: Spreads the load more evenly across the jaw, potentially reducing wear and tear.
  • Redundancy: If one implant encounters issues, the remaining five still provide ample support.


  • Higher Cost: Typically, the increased number of implants leads to a higher overall treatment cost.
  • Lengthier Procedure: The surgery might take longer, and the overall treatment could extend over more appointments.
  • Bone Quality Requirements: Generally requires a better quality of bone, potentially necessitating bone grafts.

In the realm of full-arch dental restoration, both All on 4 and All on 6 have their respective merits and considerations. While cost, procedure duration, and bone quality might influence one’s decision, the overriding factor should always be the specific needs and circumstances of the patient.
