Dimensional changes in the alveolar process after tooth extraction have been documented, and immediate implants alone have failed to prevent such changes.
Contrarily, immediate implant installation together with gap filling, minimally invasive extraction, threedimensional prosthetically guided implantation and use of immediate provisionalization demonstrated predictable functional and esthetic outcomes to replace teeth.
Immediate implants have been indicated only in fresh extraction sockets with an intact buccal bone wall.
However, treatment protocols that allow highly predictable and little traumatic successful outcomes, preferable in one single surgery, have been pursued in implantology.
