No full textComputer-Aided Surgery and Immediate Loading to Rehabilitate Complete Arch with Four Dental Implants and Fixed Screw-Retained Prosthesis Up to 4 Years in Function: A Retrospective Study
No full textPurpose: The aim of this study was to analyze retrospectively the clinical reliability of complete-arch rehabilitations with screw-retained fixed prostheses supported by four dental implants inserted with a fully guided surgical protocol. Materials and Methods: All the implants were placed between December 1, 2015, and April 30, 2019. Digital implant surgical planning was performed for all the complete-arch rehabilitations, and then, fully guided surgery was performed. The fixed provisional prostheses were delivered the day of the surgery and replaced by definitive prostheses after the healing period. Patients were followed up to determine survival of the implants and success of the overall treatment. Results: A total of 160 implants were positioned in 37 patients, with three patients receiving rehabilitations in both arches. A total of 40 complete-arch rehabilitations were performed, 26 in the maxilla and 14 in the mandible. Only five implants failed, resulting in an overall implant survival rate of 96.9%. No definitive prostheses failed, resulting in a 100% prosthetic success rate. The failed implants were successfully replaced before definitive prostheses were made, resulting in an overall treatment success of 100%. Conclusion: Within the limitations of this study, digital planning and guided surgery to perform complete-arch rehabilitations on four dental implants seems to be a valid treatment option. However, several prospective studies with longer follow-up are needed to achieve more predictable results
Immediate restoration of a single upper central integrating digital workflow and a novel dental implant: a case report
No full textThe aim of this study is to report the integrated digital workflow with a novel dental implant to rehabilitate a single tooth in a high value aesthetic zone. A 50-year-old man asked to rehabilitate tooth 1.1. The use of an integrated digital workflow in combination with computer guided surgery allow the clinician to visualize all patient's information when planning the rehabilitation in order to obtain a more predictable and a less invasive surgery. After two months of follow-up there were no biological or prosthetic issues. Within the limitation of this study, the digital workflow to rehabilitate a high value aesthetic zone could improve predictability and accuracy in immediate loading restoration

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
