Abstract
Patient: An 82-year-old woman presented in our clinic with a masticatory disorder caused by an unstable complete mandibular denture. Her maxillary teeth consisted of a fixed prosthesis. The mandible was edentulous with severe bone resorption in the molar region. After consultation, prosthetic treatment was recommended only for the edentulous mandible. Four implants were placed in the anterior part of the mandible, and an overdenture was set using a bar attachment.
Discussion: A comparison of Yamamoto’s masticatory efficacy before and after treatment indicated that the prosthetic treatment using an implant overdenture resulted in an improvement of masticatory efficacy.
Conclusion: Implant overdentures are effective and bring favorable long-term outcomes for patients with mandibular single denture with severe residual ridge resorption.
