| Popis: | 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. |
