Purpose To retrospectively evaluate complications associated with overdentures and abutment teeth restored with metal copings, including post‐procedural and prosthetic problems; also to analyze the frequency and influencing factors associated with these problems. Materials and Methods A total of 80 subjects (48 females, 32 males, mean age 62 years) wearing root‐supported overdentures were enrolled in the study. All participants were thoroughly examined by a single examiner, and appropriate maintenance care was performed. The 80 subjects had 270 abutments, which were endodontically treated teeth. All 80 subjects were carefully interviewed, inspected, and evaluated for post‐procedural and clinical problems with their overdentures for an observation period of up to 5 years. Results Of the post‐procedural problems evaluated, the most common problems were gingival inflammation (69%) and root caries (36%) because of poor oral hygiene (41%) and loss of metal copings (34%), followed by overdenture base fracture over abutment teeth (34%). Other post‐procedural problems reported were loss of overdenture stability (23%), incidence of overdenture repair (20%), poor retention (18%), incidental finding of root fragments (unplanned) in the jaws (15%), and up to two grade net change in the mobility of overdenture abutments (8%). All prostheses were in use at the time of data collection and observation up to 5 years. Conclusions Overdenture therapy was satisfactory; however, post‐procedural and prosthetic complications and aftercare maintenance must not be underestimated.
