Introduction to All-on-4®

An All-on-4® is a procedure for people looking for an alternative to removable dentures. Over 42% of people over the age of 65 have no teeth. Many detest the idea of having to remove their dentures at night or feel them shift around while they chew. With an All-on-4®, these concerns are completely eliminated, giving the patient the closest thing to natural teeth currently possible. Four (sometimes more, rarely less) implants are placed into the jaw bone with a denture attached directly to the implants. After a brief period of time, the patient has a smile (and bite) of which they can be proud.


Restorative doctor and patient

Communication between the restorative doctor and the patient is vital. The patient needs to clearly express their needs and desires to the doctor, and the doctor must accurately lay out the relevant options to the patient. With adequate communication, together, the patient and doctor can reach a solution that best suits the needs of the patient.

Restorative Doctor and Surgical Doctor

After the doctor has discussed all of the options with the patient and they have determined the best course of action, the restorative doctor and surgical doctor need to discuss the specifics of the case. It is vital to plan the procedure step-by-step to tailor it to the specific needs of each patient. The bone density, angle, implant placement, implant type, and medical history should all be discussed and considered. Well-placed, properly sized implants in healthy bone yield the highest quality results.

Doctors and Lab Technician

It is crucial that both doctors maintain an open line of communication with the lab, and for the lab technicians to keep the doctors informed of any potential issues or delays. The lab will be fabricating a temporary denture to be fixed in the mouth immediately following the surgery. Any miscommunication could result in the patient having to wait, without teeth, for several days. Proper impressions of both arches and a bite registration are crucial for fabricating a denture for immediate load. The lab will also be fabricating the final prosthesis, which will hopefully remain in the patient’s mouth for decades.

If everybody does their part, and keeps all other parties informed, the patient will leave happy and smiling, knowing that for the first time in possibly years they have a full set of teeth.
