case_images: Tehran University of Medical Sciences, School of Dentistry, involving an 83-year-old female patient with Parkinson's disease seeking overdenture rehabilitation. The patient presented with a broken mandibular implant-supported overdenture and a worn maxillary complete denture (Figure 1).
