What you are looking at are the broken, decayed roots. The orange dots inside the teeth are root canal remnants.
The upper back teeth often time take the longest of all the teeth to replace. This is because the bone is very soft in this area. It is soft because the bone is full of bone marrow rather than the hard bone cortex. Softer bone takes longer to heal around dental implants than harder bone. I highly suggest watching this short video. (if you cant see it click this link: http://www.dentalimplantdentistryblog.com/2009/08/video-hard-or-soft-bone-what-is-better-for-dental-implants.html)
Her plan and timing were as follows:
Extract the teeth and bone graft the sockets> Wait four months for initial healing > Place the implants with an internal sinus lift for the upper right back most molar> Wait four months for the implants to heal > Make impressions for the real porcelain teeth and send to the lab > Place the final abutments and cement the bridges.
If you do the math, this turns out to be about 9 months. Many areas of the mouth can be done as same day procedures without the wait. In other instances, going slow with each step greatly increases the chance of success. Each person and situation is so different.
In her case, two implants were used on each side to support "three unit bridges." This means that three teeth are being replaced with two implants.
She was so happy. She will be returning to have dental implants for her lower missing molars!
