The All-on-4 dental technique has changed the face of implant dentistry since its inception. The protocol was first developed by Dr.Paulo Malo and his team in 1993 based on dental implant concepts that had been prevalent since the 1960s. This ground breaking technique utilized as few as four implants per arch, as opposed to the 6-8 implants that were utilized in traditional implant techniques. Malo’s All-on-4 technique is both time and money-saving, while it also does not necessitate additional bone-grafting techniques in most patients. While offering many benefits, it is crucial that the procedure be carried out by an experienced dental professional after careful planning. The rehabilitation has to be performed to exacting standards so it can be carried out on the same day, while yielding the desired results in a secure manner. Dr. Dan Hagi has both perfected and improved many aspects of the original all-on-4 dental implant procedure through his many years of experience for better results.
The All-on-4 dental implant protocol is an innovative technique that is well-suited for edentulous conditions, terminal dental conditions and cases where patients are unable to have traditional implants installed due to insufficient bone. The main draw for these dental procedures is that they allow for immediate loading of dental prosthetics and do not require complex grafting procedures. The All-on-4 concept makes use of the existing bone volume in the patient, even if it is scanty, so there is minimal need for bone grafts. This reduces the complexity of the dental restoration procedure, while preventing complications like bone deterioration.
The ingenuity of the All-on-4 dental implant protocol facilitates same-day placement for lower/upper or both arches. The best part is it utilizes a minimum of four implants, as the name suggests. In other words, a complete arch is supported on just as little as four to six titanium implants that serve as pillars. The bridge latches onto the titanium implant posts, and holds the prosthetic teeth in place. All-on-4 dental implants look, feel and act just like your natural teeth and enhance the bite force by nearly 70 percent. They are a solid dental prosthetics that stay firmly put without requiring adhesives or to be removed. Your new teeth are cared for like natural teeth and can be brushed and water-pik’d like natural teeth and do require twice a year professional cleanings just like your natural teeth did.
The All-on-4 dental protocol is minimally invasive in nature, allowing for a full arch to be fixed on as few as four implants. The All-on-4 dental implants use tilted back implants to support the dental prosthetic, which is why it is feasible even in cases where there is very little bone volume in the jaw structure of the individual. The 45-degree inclination of the back implants prevents it from getting in the way of the nerve canal and sinus cavity of the jaw, thereby lowering risks and reducing the need for grafting as well as utilizing the skeletal hard bone of the face.
The principle behind the working of the all-on-4 dental implant is very similar to engineering concepts that we use. The implants are angled in such a way that they form a trapezoidal force, which can hold the full-arch of teeth, very similar to how an inverted truss behaves. For those who do not know what a truss is, it is basically a frame that is used to support bridges and roofs. A truss is built by using straight structures so they form triangular frames by joining them at the nodes. An external force that is applied affects just the nodes, and the corresponding straight members. The force manifests as compressive or tensile forces. The same principles are also applied when you drive in nails through wood in carpentry. While you can no doubt hammer it in straight, driving it a slight angle will enhance the grip and strength.
