The All-On-4 Treatment Concept is an efficient and effective restoration that uses four to six implants to support an immediately loaded full-arch prosthesis. This solution is for edentulous patients who don’t have much bone left to retain dental implants; often such patients require extensive bone grafting, which is time-consuming and expensive. All-On-4 not only gives practitioners a process directed at those marginal patients but also allows for a full smile reconstruct in only a few visits.
