Abstract
Implant-supported removable overdentures are a popular treatment option with a favorable impact on a patient’s quality of life. A maxillary removable overdenture without palatal coverage should be supported by at least 4 implants uniformly distributed around the arch and connected by either semiprecision attachments or a bar. Optimally these 4 implants should be parallel or have their long axes nearly aligned to facilitate the prosthodontic phase of treatment by allowing the use of standard components. A computer-aided design and computer-aided manufacturing (CAD-CAM) procedure to produce LOCATOR-style attachments (T-L Custom abutments; TruAbutment Inc) to manage the restoration of 4 misaligned implants is described.
