Just something to be aware of in terms of potential complications with implants is peri implantitis. You can't just have them installed and walk away, they need to be cleaned, maintained, and if you have a screwed in implant - tightened. Many dentists forget to inform patients of what is involved.
Here's a wikipedia entry:
Quote:
Peri-implantitis is the destructive inflammatory process affecting the soft and hard tissues surrounding dental implants. The array of periodontal pathogens found around failing implants (those affected by peri-implantitis) are very similar to those found in association with various forms of periodontal disease.
