When there isn’t enough bone available, most times an additional procedure called guided bone regeneration can be done at the same time as the implant placement. In very rare cases, if there is very little bone, then the bone regeneration procedure would need to be conducted before placing the dental implant.
“What does it involve? I am worried now, as it sounds scary”
Rest assured, this is a common procedure, and in most cases because we do this procedure at the same time as implant placement there is only a minimal amount more of pain and/or swelling which is very well controlled with medications that we will prescribe to you.
There are a few sources where the bone comes from, however the most commonly used source is from a bovine origin (Bio-Oss). There are also other alternatives available such synthetic grafts or allografts.
Bone regeneration around the implants is conducted with support of biomaterials such as Geistlich Bio-Oss® and Geistlich Bio-Gide®.
When conditions indicate that bone grafting is necessary, the time it takes to finish treatment will usually increase. In most cases, dental implants are ready to be used after three months if no bone grafting is required. If bone grafting is required, the treatment time is generally increased to four to nine months depending on the amount.
The implant is not surrounded by bone here and the threads are visible.
