Abstract
Patient: A 59-year-old woman visited our hospital with a chief complaint of masticatory dysfunction due to breakage of lower bilateral distal extension missing denture. After temporary repairs, a fixed partial denture at upper anterior teeth was detached. Full mouth restoration was done to correct the defect of occlusal support with sunk dentures and slight infraocclusion. During 6 years of follow-up, only one tooth was extracted due to root fracture, thus the prognosis was considered stable.
Discussion: Occlusal reconstruction for decrease of occlusal support with active prosthesis is considered to prevent occlusal collapse in the long term.
Conclusion: Concerning case of Eichner classification B2, the recovery of function and aesthetics mainly using removable partial denture provides good prognosis.
