Dental implants can be placed 10 years after tooth extraction, but the basic conditions for dental implants must be met. If the neighboring teeth on both sides are tilted and the gap between the extracted teeth becomes small, which is not enough to accommodate the implant, dental implantation is not possible, and it is necessary to perform orthodontic treatment on the neighboring teeth on both sides to restore the gap between the missing teeth before dental implantation. If the missing tooth causes the elongation of the opposite jaw teeth, dental implants are also not allowed, and the opposite jaw teeth need to be depressed by conventional methods to obtain enough occlusal space before dental implants can be implanted. If there is insufficient bone tissue, dental implants are also not possible. Surgery needs to be done first to deal with bone augmentation properly, and then implant surgery can be performed again. Therefore, dental implants are also possible 10 years after tooth extraction, as long as the basic conditions for dental implants are met.
