All on 4 vs. Full-Arch

Dental surgery can be daunting for patients when deciding on the most appropriate treatment. Many options exist, but people are unclear about what route to take. The All-On-Four method and Full-Arch implants are the most common treatment options for dental implants. There are some commonalities between both options. Let’s look at some of the benefits that may sway your decision.


What are All on 4 Dental Implants?


Developed by Professor Paulo Malo during the 1990s, All on 4 is a popular treatment option for those needing dental implants. The surgery involves inserting four titanium screws into the upper, lower, or both of the jaw, accompanied by a non-removable bridge supporting the screws.


A common trait of the procedure is that the implants are placed at a 45-degree angle, reducing the need for a bone graft if they lack the appropriate amount of jawbone needed for the surgery. While this isn’t ideal for patients, a bone graft will help long-term by having the correct structure in place for the All on 4 implants.

Expression of interest for this surgery is subject to a few health factors that may impact whether you’re eligible for this procedure. For more information, visit our All on 4 dental implants page here.


Advantages of All on 4 Surgery

There are many advantages of going for All-On-4 surgery with Aria Dental. The most common include:

  • Fast-Turnaround Times – Turnaround for this particular procedure is typically 3 days but can be carried out on the same day with Same Day Teeth Other implant avenues can take more time and may require intermittent visits across the year to complete your surgery.


  • Mirrors Real Teeth – Implants are crafted by our head prosthodontist Dr. Michael Zaninovich which mirrors the look and feel of natural teeth.


  • More Economical – With different implant techniques on the market that require procedures such as bone grafting (if you don’t have enough bone in your mouth) or inserting more than 4 implants, All-On-4 removes the need for this by reducing what’s required to obtain dental implants.


  • High Success Rate – With countless procedures performed year-round, there are few cases of failure. At Aria Dental, we have a 98% success rate of prosthetic retention with our implants.


All on 4 vs. Full-Arch Fixed Implants

Full-Arch Fixed Implants are similar to All On 4, using an implant method inserted into the jaw.

The main difference is the number of implants and stress put on the jaw ranging from 8-10 implants for Full-Arch compared to just 4 with the All on 4 treatment.

Dental implants require multiple visits, which can take a bit longer to complete, with the All on 4 procedure completed in just a few days.

Moreover, a factor that impacts the overall procedures is, of course, price. With more implants and time investment needed with Full-Arch Fixed Implants, the cost associated with this is much higher than that of All-On-4. Expenses exceed in the tens of thousands with fixed implants, whereas All-On-4 is a much more cost-effective method that yields similar, if not better, results.


Advantages of Full-Arch Fixed Implants

There are a few advantages of going with the Full-Arch Fixed Implant method. This includes:


  • Improved Support Structure – Opting for full-arch fixed dental implants prevent teeth that are next to each other from moving around. This creates an excellent structure and reduces the amount of alignment issues commonly found with other dental implant surgeries.


  • Aesthetically & Functionally Pleasing – Full-Arch Fixed implants are a great alternative aesthetically, mimicking the look of normal teeth but better functioning due to the materials used to create the implants.

Which is right for you?


Aria Dental is led by our registered Specialist Prosthodontist Dr Michael Zaninovich, and our focus is on advanced functional and aesthetic dental rehabilitation.

We favour the utilisation of ceramic bridges over bridges made from acrylic reinforced with metal. Ceramic zirconia bridges currently offer the highest level of quality and function for tooth replacement and are preferred over acrylic bridges.

 We favour ceramic bridges due to

  • Aesthetic Customisation: With ceramic bridges the tooth shapes, colours and contours can all be hand customised by the dental ceramist.
  • Strength: Ceramic is currently the best material that we can offer in terms of strength and most suitable to endure the harsh environment of the mouth.
  • Longevity: All prosthetic materials have a very long, but not an unlimited, life span but ceramic will last much longer than acrylic
  • Cleansability: Ceramic is easy to clean because plaque does not adhere to the ceramic material
  • Preservation of Bone: The critical benefit of ceramic restorative materials is that the surgeon aims not to remove any bone because ceramic is strong even when the material thickness is reduced. This allows the replacement of teeth to be possible without or very minimal bone removal, to achieve the most aesthetic and natural set of teeth possible.
  • Biocompatibility: Ceramic materials are very biocompatible. The gum tissue above the bridge seals better to unglazed ceramic material, when compared to acrylic. A tight seal of the gum tissue to the ceramic is the first line of defence against bone loss and implant inflection. The risk of allergy to ceramic is negligible compared to acrylic materials.
