What Is All-On-4? All-On-4 refers to a dental procedure where a prosthesis (bridge) is inserted to replace all teeth in either the upper or lower jaw. This prosthesis is supported by at least 4 implants. This treatment option can be life-changing, the patient has a set of fixed teeth instead of removable dentures that will sit in a denture cup at night. Dr. Le has successfully completed many All-On-4 cases, performing both the surgical and restorative components. At Bunker Hill Dentistry we prioritize convenience and perform the entire operation in one day, saving you time and money. If you are missing teeth, contact us to schedule a consultation today!
