The ideal solution for prosthetic rehabilitation of the edentulous jaw. Unlike a fully fixed prosthetic replacement, a cover prosthesis requires a smaller number of implants, which, along with a higher probability of implementing the planned therapy (looking at the quantity and quality of remaining bone) and a less invasive procedure, greatly reduces the financial aspect of therapy. The main retention element is the bar, which fixed to the four previously placed implants forms the primary (patric), while the secondary (matrix) is located inside the prosthesis. With excellent retention and a completely reduced denture base, the implant cover prosthesis is an ideal and patient- friendly prosthetic replacement.
