If the volume of bone is not satisfactory for the All on 6 immediate prosthesis (made in 24-72 hours), a fixed prosthetic treatment is done on six or eight implants. After placing the implants, we wait between three and eight months to complete the final fixed treatment. The waiting period depends on the condition of the bone and the position of the sinus: sometimes the bone is too weak and it is necessary to do the augmentation of the bone or in the case of bone loss it is necessay to perform a sinus lift procedure. In the period of osteointegration of implants (coalesce of implants with the bone), a classic denture is made for the patient as a temporary solution.
