Table 4: Description of normal prosthetic modifications up to seventh year in function. Thirty-three prostheses in 30 patients were remade because of prosthesis fractures (details on the number of fractures are described in Table 6). One prosthesis was remade twice. In particular, 25 original metal-resin prostheses had to be remade versus only eight monolithic prostheses. Seventy-six prostheses were remade in the recall program for prosthesis replacement. Of these remade prostheses, 17 were remade a second time, 7 because of fractures beyond repair and 10 for various reasons. \begin{table}
