Research in the field of dental implants, as well as the techniques used to place them, is constantly evolving, and our knowledge of them keeps growing. The latest evidence allows, under certain conditions, the immediate placement of implants after the extraction of teeth that cannot be restored. In appropriately selected cases, temporary teeth can also be placed on these implants immediately (teeth in a day). The choice of these techniques must be made very carefully, as it increases the risk of implant loss.
