RESUMO
The aim of this study was to identify mechanical complications associated with Nobel Biocare's angled screw channel (ASC) restorations following provision of the definitive crown. All ASC restorations provided between 1 January 2014 and 19 January 2016 were identified. Patients' clinical records were reviewed for demographic details, implant characteristics, occlusal considerations, and complications. A total of 84 implants placed in 60 patients were included. Three patients (4%) returned with mechanical complications, but the majority (n = 81; 96%) had no recorded complications. Long-term follow up is needed, but ASC restorations appear to offer a reliable and retrievable alternative to cement-retained restorations.

The aim of this study was to investigate the prosthodontic maintenance requirements of patients rehabilitated with maxillary and mandibular implant-retained overdentures using the Locator Attachment System by retrospectively reviewing case records. Fifty patients made 112 unplanned return visits over a 3-year period. The most common reasons for returning were denture adjustments (n = 45), inadequate retention (n = 39), and loosening of the implant abutments (n = 14). Implant-retained overdentures using the Locator Attachment System have comparable prosthodontic maintenance requirements to other attachment systems. Problems associated with these prostheses are usually simple to resolve chairside.
