Here is a case that was just completed today! (refer to date on post)
His lower front teeth were not savable and needed to be extracted. They were replaced with two dental implants and crowns. Pink porcelain was used to replicate the missing gum tissue and make the gum-line look more natural and easier to clean.
This is the before picture and x-ray:
These are the two implants placed in a very tight area without any incisions or bone grafts.
These are the final teeth!
This is what the implants look like on x-ray:
Hence to say, he was ecstatic with the result!
In some cases a single implant can be used to support to tooth or a cantilever can be made as an alternative.
