Implant-supported full-arch fixed bridge
Using the wonders of modern dentistry, it is now possible to replace an entire arch of missing teeth with a process known as an implant-supported full-arch fixed bridge. Also referred to as a full-arch reconstruction, it is a prosthesis designed to replace the entire dentition (all the teeth) on either the upper or the lower jaw, or on both jaws.
Utilising just 4-6 implants in each jaw, this process remains sufficient enough to support a full dental bridge and is also referred to as an “all-on-4” or “all-on-6” dental implant-supported bridge.
This prosthesis is fixed to the jaw bone and feels like your own teeth. It is a viable option for those who might be interested in fixed replacements and do not want to go down the path of dentures or overdentures.
An advantage of this procedure is that it does not always require bone grafting procedures to increase bone volume. Should the situation allow, the implants can be inserted at an angle and angulated screws used to support and retain the bridge over the implants. Patients who may not have the required bone volume for multiple individual dental implants might benefit from this.
Multiple dental implants can safely support a whole arch of permanent, natural looking artificial teeth. The bridge is fabricated with materials such as zirconia (all-ceramic) or ceramic fused to metal, supported by a titanium framework. A minimal amount of bone is required for adequate implant placement. The patient must also be relatively healthy without any adverse medical problems. A prior assessment with CBCT is an essential requirement before any implant treatment is undertaken.

A comprehensive examination
During the initial examination, x-rays are taken giving a detailed representation of your mouth. A CBCT scan is also performed to check for bone depth and bone quantity. From this, a personalised treatment plan will be skillfully formulated.
Inserting dental implants
First, Dr Kosalram, will extract any problem teeth, if necessary, before preparing the implant site. At the same appointment, impressions and a bite record are taken in order to create temporary dentures.
Then, implant posts will be surgically placed. Once in position, a set of temporary acrylic teeth will be fitted to allow for the retainment of facial shape, chewing function and speech.
The 4-6 dental implants will need several months to fuse with the bone in a process known as osseointegration. During this time, patients are free to go about their normal daily lives.
Fabricating the bridge
During healing time, the accurate impression taken earlier will be sent off to our trusted dental laboratory where a natural-looking full arch of permanent teeth is fabricated.
Insert and follow-up
After sufficient waiting time, the stability of each implant is thoroughly checked and, providing that all is well, the temporary bridge is removed and replaced with a permanent full-arch replacement. Follow-up appointments will then be scheduled in order to monitor the implant site.
