In clinical work, many patients often ask the same question: How long after tooth extraction can dental implants be done? Here I will talk about it in detail, I hope it will help you: The first situation: 3-6 months after extraction, this situation is mainly because of the posterior teeth, multi-root teeth, due to the multi-root teeth, after the teeth are extracted because of the root more extraction sockets are larger, the amount of bone is less, the implant is planted downward, there is no place to plant, we have to wait until the extraction sockets are completely healed, the planting position is good, the direction is also good, but the whole treatment It is better to wait until the extraction socket is completely healed. The second case: 3 weeks after extraction, mainly limited to single teeth or teeth with fused roots, the amount of bone is enough after tooth extraction, but the soft tissue is missing more and less, usually the soft tissue grows completely in 3 weeks, the amount of bone and soft tissue is just right after 3 weeks, and the growth factor is also the most vigorous, which is beneficial to the healing and the success of the implant surgery. The third case: implantation can be done at the time of extraction, mainly limited to single teeth or teeth with fused roots, the bone and soft tissues are sufficient after tooth extraction, and implantation at this time can greatly shorten the healing time of implantation and does not affect the cosmetic appearance of the patient, and can also reduce the loss of bone caused by tooth extraction. The fourth situation: the root tip of the extracted tooth has a serious inflammation or even a cyst, these need to be decided depending on the situation and can only be implanted after the inflammation or cyst has completely healed. The fifth case: before and after extraction, those who have recently had radiotherapy or chemotherapy, usually need to wait for 2 years before considering implantation.
