When should they be placed?
In an ideal world, implants would be placed whenever teeth were removed. This is simply not practical in the vast majority of cases. It is still better for implants to be placed, at the dentist’s discretion within three months of extraction to maximise the bone quantity. This does not mean that people who have lost teeth many years ago cannot have implants; it just means that there is more need for compromise when the bone and gum have reduced.
