Unlike standard implants, which use somewhere between 5 and 8 implants in one arch, the All-On-Four treatment only requires 4 implants to replace every tooth on an upper arch. The All-On-Four treatment uses your bone’s intrinsic support to boost support through the angled placement of the posterior implants. Traditional implants also frequently need bone grafting, which might take up to 6 months to complete. The All-On-4 Dental protocol requires no bone grafting for most patients, with a success rate that is equal to or better than traditional implants.
