This is a very unique case where a large sinus bone graft had to be performed for just one dental implant. This example below was done at my office in Burbank.
The sinus was so expanded from bone loss that an “internal sinus bone graft” would not work. There was not enough pre-existing bone to do that technique which reduces cost and time.
On a side note, many patients mistake the word “graph” with “graft.” “Graft” is the proper term for “grafting” bone or tissue such as gums or skin.
Here is how he started with one missing tooth and no bone in the area. This is a hollow sinus in the area of the upper left first molar #14:
This is what the sinus looks like from the inside from the CT scan. Double click to enlarge the image.
My virtual surgical planning software allows me to do surgery on the computer before the real dental implant or bone grafting procedure.
The purple object is the dental implant plan and the red drawing is how much bone is missing. That is a lot of missing bone!
Here is the x-ray after the bone graft. The implant is 16mm long and there is still bone beyond it. I was able to build about an inch and a half of bone for this patient!
It was allowed to heal for 4 months.
When you look closely at the implant near the top, you can see that the bone is dense near the neck. Now he can put the tooth on the implant!
Can you see the bone growth? Feel free to comment below. No need to sign up!
