DOI: 10.11607/ijp.5150, PubMed ID (PMID): 28453001Pages 258-259, Language: EnglishGreer, Anna C. / Hoyle, Philippa J. / Vere, Joseph W. / Wragg, Phillip F.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.
