The aim of this article is to re-examine specific indications for immediate implant placement and to clarify the timing or "fourth dimension" relative to extraction and implant placement. The expanded concept of four-dimensional implant treatment planning involves the new axis of time, which must be considered along with the traditional spatial or threedimensional management of implant positioning.
