The author describes a female patient in whom complete lower prosthesis had to be made for the first time. For improving the stabilization of the prosthesis had to be made for the first time. For improving the stabilization of the prosthesis and facilitate the adaptation it was planned to carry out intra-alveolar implants by Wierzyński's method inserted into freshly emptied alveoli. The immediate prosthesis was a specially adapted prosthesis which had been worn previously by the patient. After healing of the post-extraction wound and epithelialization of alveoli final prosthetic replacement was prepared, i.e. upper partial prosthesis and lower complete prosthesis with intra-alveolar implant.
