Patient: A 70-year-old woman visited our clinic with a chief complaint of chewing difficulty due to serious periodontitis and an improper RPD. A poor prognosis of the maxillary anterior residual teeth was predicted. However, the patient' s consent for tooth extraction could not be obtained. Consequently, the RPD was designed for the future additional tooth.
Discussion: The maxillary RPD has been functioning for 9 years through repeated additional teeth and repairs. Designing of the metal plate for the predicted prognosis allowed for additional teeth and repairs after losing of the residual teeth.
Conclusion: Designing of the denture for the predicted prognosis allowed long-term continuous use of the denture.
