Implant Tribune Italian Edition - Marzo 2016 9 Speciale digital dentistry sweden-martina.com Riscuotendo l’entusiasmo dei clinici un gruppo di implantologi selezionato dal dott.Cannizzaro di Pavia ha dato vita al Syra Team, uno study group che attualmente sta eseguendo un trial clinico randomizzato multicentrico su protocollo del dott.Marco Esposito, Editor dello European Journal of Oral Implantology. Syra, la risposta semplice. Dal paziente completamente edentulo alla riabilitazione singola, l’impianto Syra semplificherà il tuo lavoro.Come? Con la connessione unica,con la possibilità di scegliere spira e superficie più adatta ad ogni caso clinico,con la protesi Skin, anodizzata rosa,che minimizza la trasparenza sotto i tessuti molli. Syra Team A volumetric 3-D digital analysis of dimensional changes to the alveolar process at implants placed immediately into extraction sockets Isacco Szathvary*, Marco Caneva**, Martina Caneva**, Eriberto Bressan***, Daniele Botticelli** e Roberto Meneghello* *Department of Management and Engineering, University of Padua, Italy **Ariminum Research and Dental Education Center, Ariminum Odontologica, Rimini, Italy ***Department of Neurosciences, School of Medicine and Surgery, University of Padua, Italy < pagina 1 In that review, the methods of measurement of the dimensional variation between the time of ex- traction and the subsequent period of reanalysis were also reported. For the hard tissue, radiographs, computed tomography scans, cone beam computed tomography scans, or reentry surgical proce- dures that included stents or other references were used for the analy- sis of the dimensional changes. For the combined hard- and soft-tissue dimensional changes, the casts mainly were analyzed. Dimensional changes to the al- veolar process may be analyzed using digitalized images (mesh- es) obtained by various 3-D digi- tal methods: on casts, using laser scanners and structured-light 3-D scanners,2 or chairside using 3-D intra-oral photogrammetric systems.3 The reproducibility of these methods has been shown to be high and their use for ana- lyzing dimensional variations of the alveolar process has been recommended.4–6 Many of the re- cent studies that have used 3-D systems to analyze dimensional variations of the alveolar process, how- ever, lost substantial infor- mation in transforming 3-D data to 2-D measurements.7,8 Volumetric data instead were re- ported in a clinical study in which augmentation procedures were used at implants placed in eden- tulous ridges reduced in volume.9 In the study, a grid was superim- posed on the images so that both the global difference in volume before and after treatment and the differences in specific areas were reported. 2-D variations of the hard tissue around implants placed immediately into extrac- tion sockets have been reported in clinical studies,10,11 and, in an animal study, combined hard- and soft-tissue 2-D changes have been analyzed.12 However, there is a lack of studies that report volumetric data on combined hard- and soft-tissue variation at implants placed immediately into extraction sockets in humans us- ing a 3-D system. Hence, the aim of the present study was to vali- date the use of a novel method to elaborate 3-D data on dimension- al changes to the alveolar process after one year of follow-up at im- plants placed immediately into extraction sockets. > pagina 10 Richiedilatuacopiagratuita scrivi a segreteria@tueorservizi.it o sfoglia il PDF in versione E-Paper sul sito www.dtscience.com Implant Tribune Italian Edition - Marzo 20169
