Bone grafting and implants
about when, if at all, you need to get the bone grafting done should be
determined by your dentist. It depends on the amount of available bone at the
time of the extraction. Bone grafting helps replace missing bone, so a properly
sized implant is placed.
dentists prefer to perform a procedure called “socket preservation,” which is a
procedure to reduce bone loss after tooth extraction to preserve the dental alveolus
(tooth socket) in the
bone graft helps to maintain bone height and width . so it is advisable to go for bone graft during extraction. ans 1. bone graft is not necessary but it will help to maintain bone quantity. 2. later, if bone quantity is not proper [ height and width] for implant than u have to go for additional surgery. so best option is to go for bone grafting at the time of extraction.
It is best to graft immediately after extracting the tooth. This way the bone heals and when the implant is placed, it is surrounded by new bone. Otherwise the bone may shrink & to get that back is more difficult & results would be less ideal.
