All-on-4 concept is a dental implant technique that uses fewer implants in the upper or lower jaws than the traditional methods. This procedure can also avoid the need for certain grafting procedures. On average, a traditional full dental implant rehabilitation of the upper jaw would require between 6 and 8 implants, whereas the new technique would only need 4 implants. With the All-on-4 concept, the rear implants are inserted at a 30 to 45 degree angle rather than vertically. With this new method, patients who suffer from bone loss can still be eligible for the procedure without going through the extensive and lengthy process of a bone graft.
The ideal candidate for an All-on-4 are patients who have lost all their upper or lower teeth or patients who have bad teeth that need extraction and want to replace them. The removal of teeth with the All-on-4 procedure can be done on the same day as the implant placement.
Dentures are custom made to each patient’s jaw and fit over the gums. They stay in place using suction or sometimes require the help of a dental adhesive. However, over time, the supporting bone shrinks, and the denture becomes looser. Denture needs to be replaced regularly to avoid discomfort. The All-on-4 technique involves dental implants that are permanently inserted into the jaw bones. There is no risk of the teeth slipping away while eating or talking. There are several other differences between the All-on-4 concept and a denture including; a more natural look, the ability to eat all foods.
The major advantage of the All-On-4 concept is that the patient leaves the office with teeth in their mouth and the ability to chew food on the day of the surgery. This differs from the conventional technique that requires a minimum of 3 months before putting any pressure on the implants.
Here are some more advantages of the new dental implant technique:
All-on-4 dental implant technique is a fairly new approach; however, studies show good success rate after 10 years with 94.8% to 98.0%.
