The All-On-4 (All-On-Four) Dental Implants is a dental implants technique originally developed in order to help edentulous patients with severe bone loss at the posterior areas of the jaw to get the benefits of implant supported dentures. Since then new technique has appeared, the immediate loading implants technique which can be used also in case patients with severe bone loss. All-On-4 technique however can be combined with immediate loading implants.
All-on-6 and All-on-8 are variations of the same technique, but using a larger number of dental implants.
The All-On-4 implants system was invented by Dr. Paulo Malo in the 80’s. The system is based on principles regarding dental implants that were accepted as far back as the 60’s, and Dr. Malo evaluated these and determined a clear, comfortable work protocol. Today, there are many improvements to Dr. Malo’s original protocol. The system is based on placing 4-6-8 implants in very specific locations to create a three dimensional trapezoid force that enables the attachment of dentures or a bridge containing 12 teeth. Very careful planning and broad surgical experience is required. The replacement must be prepared very thoroughly so that implants and the replacement can be done on the same day. The vast experience we have at our clinic ensures uncompromising quality and reliability.
This method is also suitable for patients with removable complete dentures. Using this technique we can make the removable denture fixed, provided the denture is still in good quality and we can perform the necessary adjustments on it. If not we provide new denture/bridge.
All-on-4 can provide the following advantages:
- All-on-4 provide a cheaper solution for patients with very poor bone condition
- Fewer implants can be used, lowering the cost of the overall treatment
- It is also performed with immediate load technique at our clinic so the treatment time is usually one day
Before you decide to take advantage of the all-on-4 dental implants you should first consider some of the risks involved:
- Higher and Combined failure risk – If one of the 4 supporting implants fails, the entire restoration fails and has to be reconstructed.
- Jaw fracture risk – Implants are placed only in the front jaw, therefore the jawbone deterioration continues at the posterior areas of the jaw increasing the risk of what is called a ‘facial collapse’. If it becomes too weak, the jaw may fracture due to the pressure applied to the front part when eating.
All-on-6 dental implants is just a variation of the all-on-4 technique based on the same concept, with the only difference that 6 front implants are used instead of four. Many dental implant dentists prefer the ‘all-on-6’ option because it is safer (a restoration can be placed even if one of the implants fails).
Another variation is the All-on-8 using 8 dental implants. Unlike the ‘All-on-4’ technique which uses acrylic dentures, ‘All-on-8’ uses dental bridges with crowns, which gives a more natural look to the teeth.
All of these variations are available at our dental clinic and performed with Swiss immediate loading dental implants.
