Dental Implant Techniques

What is the All-on-4 dental implant technique?

All-on-4 is a dental implant technique developed by Dr. Paulo Malo in cooperation with Nobel Biocare, one of the world’s leading dental implant manufacturers, in the late 1990s. It is a revolutionary dental procedure because it only uses four implants to support the 12 to 14 replacement teeth per jaw. Conventional dental implants normally require six to eight implants per jaw to support the same number of replacement teeth.

The All-on-4 treatment protocol also allows patients who are not considered ideal candidates for conventional implant supported bridges to get their new set of teeth in a matter of days. Typically, people who have already lost all or most of their teeth will also have suffered from advanced bone loss in the jaw due to bacteria eating away at the jawbone. In these cases, conventional dental implants can’t be surgically inserted into the jaw because there isn’t enough bone volume directly underneath the teeth that need to be replaced. Patients will first have to get a bone graft and wait for new bone tissue growth before they can get their dental implants. Using the All-on-4 method, however, bone grafts are no longer necessary because the two implants in the rear are angled so that it can be placed in areas where there is enough bone volume. This treatment concept requires proper planning prior to the procedure and oral surgeons with specialised training and expertise in order to be effective and long lasting.

What special techniques are required for the All-on-4 treatment?

In order to ensure long-term success, All-on-4 treatments need to follow the same protocols that have been perfected by Dr. Malo. Prior to the implant surgery, our surgeons will perform a 3D CT scan of your mouth and jaws in order to accurately visualise and properly plan the procedure before making the first incision. During the procedure the surgeon will use the Malo guide to properly angle the four dental implants in the arch. This measurement device has been designed specifically for the All-on-4 treatment.

Once the All-on-4 implants are in place, an impression will be to determine the exact position of the implants which will help our lab technicians create a temporary bridge that will fit perfectly. The temporary bridge provides patients with immediate results while waiting for the dental implants to fully heal. It will look just as good and function like the permanent bridge, and can only be removed in the clinic.

Malo Dental Sydney uses advanced CAD/CAM technology to create a perfect looking set of teeth that will give you back a great looking smile. It also allows us to create an exact fit so your new set of teeth will function as well as healthy and natural teeth.

Are there different types of All-on-4 techniques?

All-on-4 was originally developed to improve dental restoration techniques for the lower jaw. After the initial trials and long-term evaluations proved to be successful, it was then adapted for upper jaw dental restorations, which is slightly different because the implant can get in the way of the sinus cavity.

In some cases where there is too much bone loss in the upper jaw, zygomatic implants are necessary. Zygomatic All-on-4 implants are much longer than regular implants and are used so that the rear implants can be placed in the cheekbones where there is adequate bone volume to support the implant.

Are some All-on-4 techniques more expensive than others?

Zygomatic All-on-4 implants are usually more expensive than regular All-on-4 implant surgeries. Since the longer zygomatic implants are placed in the cheekbone and not just the jawbone, it is usually performed under general anaesthetic, which adds to the cost of the procedure. The zygomatic implants are also more expensive and may have to be customised to suit each patient’s needs. In some cases, two sets of zygomatic implants may be required, for a total of six implants in the upper arch. This procedure is referred to as Quad Zygoma.

Titanium implants have long been used for All-on-4 procedures because of the material’s strength and durability. These are also non-toxic and biocompatible materials, meaning it can easily integrate into the jaw once new bone tissue attaches itself around the implants.

Compared to more affordable implants made out of zirconia, titanium implants are much more versatile especially when used as a two-piece system where implants can be placed right at the level of the underlying bone and a separate post or abutment is used to attach the dental prosthetic. Two-piece implants can be easily placed at more aggressive angles since the post can be customised to accommodate a better fit.

The dental prosthetic or bridge can also be made out of either ceramic or acrylic. Ceramic bridges are much more expensive than acrylic ones but offer a lot more durability and are more aesthetically pleasing.
