[Immediate extractions-implantations]

Immediate implants are implants placed into a prepared extraction socket following tooth removal. Short-term animal and human studies have shown these implants to be comparable to implants placed into healed bone. The results in term of bone integration can be optimised by a better consideration of the surgical site. The evolution of the concept of the immediate placement of endosseous implants into extraction sites, along with the related concept of guided regeneration, is a major advancement in the surgical field. It provides significant benefit to both patient and clinician in terms of the reduced treatment time and an enhanced prognosis related to biomechanics and esthetics.
