Traditional dental implants can support one or two teeth with the use of dental bridges. The largest would be a four tooth bridge, supported by two dental implants. Using the conventional implant procedure, eight or more implants would be needed to support a full arch. In addition to the number of implants required, traditional implants have many limitations. The implants need to be screwed into areas of reduced bone density. When the bone quality isn’t good enough to support the implants, bone grafting is necessary before the implants are placed.
Conversely, the All On 4 implant technique enables the whole set of upper or lower teeth to be replaced with just four implants. The reason the All On 4 technique works is that the implants are angled at 45 degrees to avoid areas of bone deficiency. The All On 4 procedure is much less invasive, which, in turn, reduces the healing and rehabilitation process. It is also a much quicker procedure, as a full arch of teeth can be supported with just four implants.
