Introduction.The immediate implant placement in fresh extraction socket is intended to replace the tooth with no possibility of disease treatment or post-extraction of inclusions, deductions and immediate dentures. Bearing in mind that after the extraction takes place a period of bone turnover in the form of reduced physiological reabsorption of alveolar ridge dimensions, opted for regenerative therapy to reduce the after-effects. In this article the surgical technique and the handling of the soft tissue are reviewed by means of the prosthetic procedure of the immediate implant placement informed in a clinical case with a new dental implant surface. Clinical case. We present the case of a 24-year-old nonsmoker with no relevant medical history, who attends our clinic with a sharp pain of 4 days duration in the lower right first molar that has increased over time with a diagnosis of crown-root fracture. The treatment plan includes extraction of the tooth with as little trauma as possible, respecting the alveolar walls and curettage of alveolo removing all pathological tissue for insertion by submersion of a single self tapping titanium polished implant with a rough surface produced by sandblasting and Thommen Medical acid-etched heat and guided bone regeneration with particulate bovine bone Bio-Oss^®. After 6 months we place a healing screw much higher so that we can load the implant functionally with a single screwed crown whose evolution should be monitored at 12 and 24 months after surgery. Conclusion. Thanks to the advances in the field of surface treatment with this new type of self-tapping dental implant is an overall success in the field of implant treatment.
