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

Asad A | July 17, 2024

All-on-4 vs All-on-6 are two widely adopted dental implant techniques designed to restore a full arch of teeth in individuals dealing with extensive tooth loss or complete edentulism. Both methods involve dental implants to support a fixed dental prosthesis. The primary distinction between them lies in the number of implants utilized to secure the restoration.

All-on-6 relies on placing six implants per arch, offering enhanced stability and support. In contrast, All-on-4 utilizes only four implants, presenting a more conservative approach. Determining the best course of action for each patient's specific needs and expectations requires an understanding of these variations.

What are All-on-4 Vs All-on-6 Dental Implants?

All on 4 Dental Implants

The All-on-4 dental implant technique involves anchoring a full arch of prosthetic teeth onto four strategically placed implants per arch. In numerous situations, this technique eliminates the requirement for bone grafting by making use of the native bone structure. By tilting the rear implants, All-on-4 provides a stable foundation even in areas of reduced bone volume.

Advantages of All-on-4 Dental Implants

  • 1. Minimal Invasiveness: All-on-4 implants require fewer implants than traditional methods, often eliminating the need for bone grafting. This reduces surgical complexity and shortens recovery times.
  • 2. Immediate Results: Many patients can receive temporary prosthetic teeth on the same day as their implant surgery, leaving the dental office with a new smile almost immediately.
  • 3. Improved Bone Health: The implants stimulate the jawbone, which helps to maintain bone density and preserve the facial structure over time.
  • 4. Cost-Effective: All-on-4 dental implants are generally more affordable than other full-arch options like All-on-6 implants, making them accessible to patients on a budget.

Disadvantages of All-on-4 Dental Implants

  • 1. Limited Implant Support: With only four implants per arch, All-on-4 relies heavily on existing bone structure for stability. Individuals who suffer from significant bone loss or impaired bone density might not be good candidates.
  • 2. Potential for Implant Failure: Successful integration of All-on-4 implants depends on precise placement and proper bone fusion. Failure to achieve this may require additional treatments or adjustments.
  • 3. Difficulty in Cleaning: Maintaining oral hygiene around All-on-4 implants and under the fixed bridge can be challenging. Special oral hygiene techniques and tools are often necessary to prevent complications.

All on 6 Dental Implants

Similarly, all-on-6 dental implants support a full set of teeth with six implants per arch. This method offers additional stability and support, benefiting patients with stronger bite forces or more extensive bone density loss. All-on-6 implants distribute the chewing forces more evenly across the jaw, enhancing long-term durability.

Advantages of All-on-6 Dental Implants

  • Enhanced Stability: All-on-6 dental implants distribute six implants across the jawbone, significantly boosting stability. This configuration minimizes the risk of implant failure and enhances overall bite security.
  • Improved Chewing Efficiency: The additional implants in the All-on-6 treatment provide robust support, improving chewing function. Patients can eat a greater range of meals with comfort and confidence.
  • Flexibility in Treatment Planning: All-on-6 implants are adaptable to various bone conditions. They are suitable for patients with compromised bone density or those who have undergone bone grafting procedures, offering versatile treatment options.

Disadvantages of All-on-6 Dental Implants

  • Increased Invasiveness: Placing six implants in All-on-6 treatment involves a more intricate surgical procedure than All-on-4 implants. This may result in a longer recovery period for some patients.
  • Higher Cost: Additional implants in All-on-6 treatment make it generally more expensive than All-on-4 implants. Cost considerations should be taken into account when choosing the most suitable option.
  • Potential for Bone Resorption: In an all-on-6 procedure, the number of implants may eventually put extra strain on the jawbone. This could potentially lead to bone resorption, necessitating careful monitoring and maintenance.

All-on-4 Vs All-on-6 - Which One is Better for You?

Deciding between All-on-4 and All-on-6 dental implants hinges on several critical factors, each influencing which option best meets your needs and expectations.

1. Jawbone Health

The proper choice of All-on-4 versus All-on-6 implants is mostly dependent on the density and health of your jawbone. Both procedures require sufficient bone structure to support the implants effectively. All-on-4 implants are designed to capitalize on available bone volume by strategically placing four implants per arch, often circumventing the need for bone grafting. In contrast, All-on-6 implants provide additional stability and support, making them advantageous for patients with moderate to severe bone loss. If you've experienced significant bone loss, All-on-6 implants may offer superior long-term stability and durability.

2. Chewing Needs

Consider your chewing habits and demands on your dental implants. All-on-6 implants, with six implants per arch, distribute chewing forces more evenly than All-on-4 implants. Those who have stronger biting forces or who need more help when chewing rough or hard meals may benefit the most from this increased stability. If you have specific dietary preferences or habits that involve substantial chewing, all-on-6 implants might be the preferable choice to ensure sustained functionality and comfort.

3. Surgical Considerations

The invasiveness of the surgical procedure is another factor to contemplate. All-on-4 implants typically involve a less invasive approach due to the placement of fewer implants per arch. This can contribute to a quicker recovery period and reduced discomfort post-surgery. Patients seeking a streamlined treatment process or those concerned about surgical recovery may find All-on-4 implants appealing for their less invasive nature. On the other hand, All-on-6 implants, while slightly more extensive in placement, offer heightened stability and may be worth considering for those prioritizing long-term implant performance over initial surgical considerations.

4. Cost Analysis

A major consideration when choosing between All-on-4 and All-on-6 implants is cost. Generally, All-on-4 procedures tend to be slightly more cost-effective due to the use of fewer implants and potentially less required bone grafting. However, discussing your case with a qualified dentist at Dental Arts of Florida is essential to obtain a precise cost estimate. The total cost of both implant alternatives might vary depending on a number of factors, including the necessity for further procedures, the intricacy of your case, and your desired aesthetic results.

5. Consultation and Customization

 FAQs

The cost of all-on-6 dental implants in the US typically falls between $25,000 and $35,000 per arch. This range may change depending on the patient's particular needs, the location of the treatment, and the dentist's level of experience. For a precise estimate, it's essential to seek guidance from a certified professional.

These implants are engineered to support an entire set of 14 teeth using only four dental implants. They offer a strong basis for a permanent dental prosthesis that can hold ten to fourteen teeth by carefully positioning four titanium pillars.

All-on-4 dental implants provide robust support using just four strategically angled implants, maximizing bone contact. Because it reduces the need for significant bone grafting, this approach is especially advantageous for individuals with poor bone density.

On the other hand, all-on-6 dental implants offer enhanced stability by using six implants per arch. This approach ensures a more even distribution of chewing forces, making it ideal for patients with good bone density and volume who require additional support for long-term durability.
