All-on-4® is a treatment option that does not require any bone grafting. This is ideal for candidates who may have limited or poor bone quality, but still have adequate bone for dental implant placement. During this procedure, four individual implants are strategically placed to avoid the sinuses and areas of the jaw that are deficient in bone quantity or quality. This allows the implants to be placed without the need for bone grafting but still provides anchorage and stability for a permanent fixed prosthesis.
