All on Four

A Dental implant is an artificial substitute/replacement for the root portion of your natural tooth. It is a titanium screw, a material that is tolerated by bone and integrates well with bone tissue; that is placed into a pre-drilled socket in the maxilla (upper jaw) or the mandible (lower jaw). During the placement of the dental implant, the aim is to achieve a close contact with the outer surface of the implant and the surrounding bone tissue so they can ‘fuse’ together. This is known as ‘osseointergration’, which creates a stable support for the new tooth/teeth.

This is a single titanium implant, with an abutment screwed into the implant and a crown placed over this.

This is a relatively new procedure which replaces the idea that to support a full arch of teeth requires six or more implants per arch

If you are having problems with damaged, unsightly, loose teeth or suffer with ill-fitting dentures or simply can’t tolerate wearing them, then dental implants can also be used to support ‘Hybrid Acrylic Bridgework,’ also known as ‘All-on-4’. This is the placement of four implants to the maxilla (upper jaw) or the mandible (lower jaw) then once the implants have healed and osseointergrated, Hybrid Acrylic Bridgework is screwed into the Implants as a ‘fixed’ replacement to a full arch of teeth.

This is a relatively new procedure, which replaces the idea that to support a full arch of teeth requires six or more implants per arch. The concept behind ‘All-on-4’ is that the posteriorly placed implants are placed at a 45° angle and this increases their strength and ability to support a fixed acrylic bridge. Thus the need for less implants to support a full arch of teeth.
