This article aimed to evaluate whether normal osseointegration occurs in immediate loading following secondary stabilization obtained by means of conical copings and adaptation of patients' old dentures. Two clinical cases of immediate loading of implant-supported prostheses in the edentulous mandible are presented. Prostheses were positioned within 24 hours, with secondary splinting of primary conical copings screwed onto implants. For this purpose, the patients' old removable prostheses were adapted and lined to fit within the secondary acrylic resin copings, which perfectly matched the primary copings screwed onto the implants and milled to 2 degrees.
