In early September I had a bone graft done in anticipation of a future dental implant. The bone width at the time was 1mm. I am scheduled for an implant in December. Is three months a long enough period of time to allow for the additional bone growth? Is it feasible to expect growth to approx 5mm of width, which I am told is the minimum for an implant?
You are correct in saying that the 5 mm of west is the minimum amount of bone to place a dental implant. With a 3mm dental implant that gives you 1mm of bone on either side of the implant from a facial and lingual perspective. I would rather see 6-7mm for additional support of the implant and gum tissue.
There are various ways to graft bone and depending on what procedure your dentist performed, will determine how much bone width or height is achieved.
It is not unreasonable to obtain an additional 4mm of bone width through the grafting materials and procedures that are available today. In my office we utilize a Cone Beam CT machine to verify the amount of bone grown, post grafting.
The the amount of time for a graft to heal, will depend on the amount of bone needed to be grown. This will vary between a three and six months.
