To achieve the long-lasting good result of the prosthodontic treatment, the weakened tooth with a poor prognosis should be extracted before the treatment. In contrast, tooth extraction may be occasionally avoided due to several reasons. Diversified considerations are required to utilize the weakened teeth with a poor prognosis for prosthetic treatment and protect them. For the treatments with bridges including weakened abutment teeth, bridges that are placed with temporary cement and can be easily removed by the operators are effective. For the treatments with removable partial dentures, the secondary splinting with dentures designed to be connected with abutments rigidly or the applications of root coping to improve the crown-root ratios of the abutments are effective. In the prosthetic treatment with abutment teeth with a poor prognosis, both sufficient informed consent in advance and high motivation of both the patients and the operators are important factors.
