What Is “All-On-Four” And Why You Should Consider It

All-on-four implants have become a popular dental procedure that facilitates many aesthetic and functional dental concerns. This dental solution has proven to have a very high success rate in regaining a confident and healthy smile with full mouth functionality.

Despite its popularity, many people are still confused or rather unclear about what it is and why one should consider getting it done. To solve this puzzlement, here is a brief guide on what All-on-four implants are and why you may need them.


What Are  All-On-Four Implants?

All-on-four is a dental procedure where the upper or lower set of teeth are replaced with the supporting mechanism of just four implants. In other words, these all-in-four implants act as the foundation for the placement of a new set of fixed prostheses.

The full-arch rehabilitation in this procedure uses four implants, which are two straight anterior implants and two implants slanted up to 45º in the posterior. So, instead of replacing each tooth separately with an implant, you’ll receive a full set at once that’s held in place by only four strategically placed implants. This procedure offers a permanent and natural-looking alternative to dentures.

The “All” in the name of the treatment refers to all of the teeth in an arch, i.e. a full upper or lower set of teeth. Whereas the “4 or four” refers to the number of dental implants that are needed to hold the arch in place.


How Is It Different From Conventional Implants?

The dental implant procedure is generally where a small titanium screw is positioned into the jawbone to support a single or a bridge of teeth.

For a conventional dental implant procedure, a full arch rehabilitation will require at least 6-8 implants to hold a full-fixed bridge. Conversely, All-on-four requires only 4 implants.

Besides this, conventional full-arch teeth replacements have a limitation when screwing 6-8 implants into areas with reduced bone density, which calls for grafting. Grafting is an invasive procedure where the dentist will take your own bone from other areas of the body where it isn’t needed and graft it to your jawbone to build enough volume to support an implant. In contrast, as the All-on-four uses fewer implants, it means that the bone-deficient areas can just be avoided, and no grafting is required.


So, the takeaways while comparing All-on-Four and single dental implants are:

  1. Number of Implants: All-on-Four typically involves the placement of only four implants per arch, while single dental implants require an implant for each missing tooth. This means that All-on-Four can provide a full arch restoration with fewer implants compared to single dental implants, making it a more efficient and cost-effective option for patients missing multiple teeth.


  1. Support Structure: All-on-four implants are designed to support a full arch dental prosthesis, such as a bridge or denture, while single dental implants are used to replace individual missing teeth. The All-on-Four approach utilizes strategically placed implants to distribute biting forces across the entire arch, providing stability and support for the prosthetic restoration.


  1. Treatment Time: All-on-four procedures typically involve fewer surgical steps and may require less healing time compared to placing multiple single dental implants. Since All-on-Four implants are often immediately loaded with a temporary prosthesis after placement, patients can enjoy restored function and aesthetics sooner than with single dental implants, which may require a longer treatment process involving healing periods between implant placement and prosthetic attachment.


  1. Bone Volume Requirements: All-on-four dental implants are designed to utilize available bone volume more efficiently by tilting the posterior implants, which can help avoid the need for bone grafting procedures in patients with moderate bone loss. In contrast, single dental implants require sufficient bone volume and density at each implant site to ensure successful osseointegration and long-term stability. This may necessitate bone augmentation procedures in some cases.

So, choosing All-on-Four vs traditional dentures with the patient highlights the distinct advantages and considerations associated with All-on-Four and single dental implants, allowing patients and dental professionals to select the most suitable treatment option based on individual needs and preferences.

This less invasive nature makes All-on-four inherit a short healing period, and using fewer implants also makes it more flexible to design and fit the optimum replacement teeth.


All-on-Four Surgery Procedure Steps:

  • The All-on-Four surgery involves four dental implants being strategically placed in the jawbone to support a full-arch dental prosthesis.
  • After thorough examination and planning, the implants are surgically inserted into predetermined positions.
  • Following implant placement, a temporary prosthesis may be attached for immediate restoration of function and aesthetics.


Downsides of Getting All-on-4 Implants:

While All-on-Four implants offer numerous benefits, there are some downsides to consider. These include the initial cost, which may be higher compared to traditional dentures. Additionally, some patients may experience minor discomfort or temporary swelling after surgery, and there is a risk of implant failure in rare cases.


Dental Hygiene with All-on-Four Implants:

Maintaining proper dental hygiene with all-on-four Implants is crucial for the long-term success of implants. Patients should brush their teeth and prosthetic restoration regularly using a soft-bristled toothbrush and non-abrasive toothpaste. Flossing around the implants and using antimicrobial mouthwash can help prevent plaque buildup and maintain gum health.


Dental Technology Advancements in All-on-Four:

Advancements in dental technology have enhanced the All-on-Four treatment process, making it more efficient and precise. Cone-beam computed tomography (CBCT) imaging allows for detailed three-dimensional visualization of the jawbone, facilitating accurate implant placement. Computer-aided design/computer-aided manufacturing (CAD/CAM) technology enables the fabrication of custom prosthetic restorations for optimal fit and aesthetics. These advancements contribute to improved outcomes and patient satisfaction with All-on-Four implants.


Why Should You Consider It?

The advantages of all-on-four dental implants are aimed as a dental restoration solution for people who are missing all of their teeth along the dental ridge or most of their teeth. Besides this fundamental purpose, here are other reasons why you should consider this type of implant:

  • This can be done within just 24 hours in a professional dental clinic
  • Immediate results with minimal follow-up procedures
  • Simple, less invasive, and most importantly, cost-efficient compared to other conventional dental implants
  • A very short healing period
  • Those experiencing osteoporosis or a lack of jaw bone to get conventional implants can opt for all-on-four as it doesn’t require grafting or usually relies on bone density.
  • Preserves the jawbone and prevents further damage to the facial structure associated with missing teeth
  • Reduces the wrinkles associated with missing tooth or bone structure, making you look younger with a radiant smile
  • No risk of shifting or slipping because it is firmly anchored to the angulated area of the thick jawbone
  • Eliminates or reduces bone resorption (Bone Atrophy), a condition that can lead to a decrease in your bone mass and put you at higher risk for fractures and breakage
  • Regains the functional ability to normally and comfortably chew and speak, unlike traditional implants.

All-on-4 dental implants represent a cutting-edge solution for individuals seeking comprehensive tooth replacement and restoration. With the support of dental technology advancements in All-on-Four procedures, patients can benefit from improved accuracy, efficiency, and outcomes.
