It is always difficult to give you a costing as there are a lot a variables that needed to be assessed. For instance do you need a bone graft to allow for the placement of the implants, are the teeth supporting the bridge free from infection or do they need some treatment prior to making the bridge, does your bite need evening out ( equilibration ) prior to any of this treatment etc. Provided that there are no extra treatments required a typical case requiring the treatment you outlined would cost in the region of £9000.

My best advice would be for you to have a comprehensive examination to allow proper assessment of you situation.
