Waiting Period After Bone Grafting?

Kate, a dental implant patient asks us:

Do most dental implants require bone grafting? Furthermore, if bone grafting is in the treatment plan, how long do patients need to wait before a dental implant is placed?

 I was told most people need to wait approximately 2 months to let the bone graft take proper
“hold”. I was willing to wait the 2 months, but the eager periodontist
grafted and placed the dental implant at the same time. I ended up needing sinus surgery. I think the
periodontist should have stayed with the original treatment plan, and let the bone
graft “sit” for 2 months. Area of #11. What are your thoughts? I had
a bad experience , but would like to help others avoid what happened to
me. Thanks for any advice.
