These procedures recommend implants be placed and immediately have teeth put on top of them that they get full biting pressure immediately. Some people feel that implants should not have any pressure on them immediately and should wait at least 2-3 months before having pressure depending on the bone density. Many people feel that the softer the bone and the stronger the bite, the longer you have to wait before you put any pressure on implants. This is considered a more logical and reasonable approach.
