Dr Nathan Le and Professor Paulo Malo, inventor of All-on-4, at Nobel Biocare trainning centre in Sydney

 

In the mid 1990’s an extraordinary procedure was developed by a Portuguese Dentist Paulo Malo (in the photo above) in conjunction with the Implant company Nobel Biocare that permits the placement of 4 dental implants and a fixed bridge in as little as one appointment. In its most extraordinary application an entire mouthful of teeth may be replaced with implants and non-removable set of new teeth in as little as 1 day. In most cases there is no bone grafting, no sinus grafting and only minimal healing time required. This procedure is called “All-on-4”.

In the past, traditional fixed full arch dental implant techniques required 6-10 implants with a long period of healing where the bridge then be fixed to the implants. Extensive bone grafting for implant placement was often required. All on 4™ is different because you can have a full arch of replacement teeth in just one day with as little as four Nobel Biocare dental implants.

The configuration and position of the implants along the jawbone once braced together with the fixed bridge helps distribute the chewing forces transmitted from the arches of teeth to the jawbone. Two of the dental implants are placed vertically in the front of the jawbone while the other two implants are placed and tilted up to 45° at the back of the jaw, which means less bone is needed.

With the All on Four concept it is possible to achieve a new smile and a bite comparable to natural teeth in just one day. The technique was originally developed to offer patients who had experienced total tooth loss an efficient treatment concept using only four dental implants to support a full arch of teeth. This advanced technique reduces the number of dental implants required to restore an entire arch of teeth and often enables permanent teeth to be fitted to dental implants on the same day of implant placement.
