An edentulous case with severe mandibular residual ridge resorption treated using an implant overdenture

Abstract

Patient: A 78-year-old female patient complained of difficulty during mastication due to the mobility of her mandibular complete denture. Severe mandibular residual ridge resorption was observed and her mandibular complete denture lacked enough retention and stability. The patient was diagnosed with masticatory dysfunction due to poor retention of the mandibular denture which was caused by severe residual ridge resorption. She underwent prosthetic treatment using an implant overdenture (IOD).

Discussion: A bar attachment was selected for this case. An occlusal pressure impression was used to consider settling of the denture after it was placed. This led to reduced stress of the implant body and improved the fit between the denture and the underlining mucosa during function. As a result, good long-term outcomes were obtained.

Conclusions: Prosthetic treatment with IOD was performed on a mandibular edentulous patient with severe residual ridge resorption and good results were obtained.
