The ability of modern scanners to articulate digital models must be scientifically evaluated. Methods:Twenty five digital articulated models were produced from four digital scanners in five experimental groups. The resulting inter-arch measurements were compared to the gold standard. An acceptable range of 0.5mm more or less than the gold standard was used for evaluation. Results: iTero® and iTero® Element yielded all acceptable inter-arch measurements. The 3M"!True Definition and Ortho Insight 3D® with Regisil® bite registration produced four of six acceptable inter-arch measurements. The Ortho Insight 3D® with Coprwax "!bite registration yielded three of six acceptable inter-ach measurements. Conclusions: The iTero® and iTero® Element produced the most accurately articulated models. The 3M"!True Definition and Ortho Insight 3D® with Regisil® were the next most accurate. The Ortho Insight 3D® scanner with Coprwax "!was the least accurate method tested.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: TitleDigital intraoral scanners vs traditional impressions: Fitting accuracy of screwed mesostructuresBackgroundPassive fit and marginal precision of prosthetic structures on osteointegrated implants are a requirement to minimize tensions and to avoid loss of marginal bone and finally lack of osteointegration. The impression process is a primary step to obtain sufficient accuracy.We use daily intraoral scanners for impressions to made implant restorations from several years and we appreciate the clinical outcomes for passive fitting (cemented sovrastructures) and precision of screwed ones.AimThe aim of this job is to investigate the marginal accuracy of custom CoCr milled mesostructures on implants acquiring impressions by intraoral digital scanners and compare them to ones obtained bytraditional impressions systems and to evaluate if the misfit is within the optimal measure of 25-50u00b5m.Material and methodsTwo pair of implants were rigidly fixed in maxilla resin models. The first two implant were internal hexagonal flat connection implants made by Winsix implant system ( Biosaf In srl). The second two were internal octagonal conical connection implants made by Geass (Geass srl). Three impressions were took of each model. The first one was a traditional impression made by polyether material with the single impression technique. The other two impression was acquired using CS3500 Carestream Intraoral Scanner and Trios3 intraoral scanner. The digital impressions were made following factory recommendations for implant cases workflow.Milled CoCr screwed mesostructures were commissioned on the three impressions of each model.The aim was to analyze the misfit of the three mesostructures obtained using Sheffield test. The misfit was evaluated by a radiograph taken perpendicularly to the long axis of the implants. ImageJu00ae software was used to digitally process the radiographic images and perform the measurements. ResultsWe eliminate, using an artificial model some intraoral variables as blood, saliva, patient movements but we simulate the natural architecture of mouth maintaining crestal anatomy, gum, implant distance. We investigate the misfit radiographically performing the Scheffield test: in this way we screwed firmly only one screw of the mesostructure and we observe the matching of the other implant-structure connection.The bigger misfit was appreciate on the two mesostructures obtained by traditional impressions, one of them has failed to comply with the established gap limit of 50 u00b5m.Very good fitting, within the limit of 50 u00b5m was found on three mesostructures: The one made by impression with Carestream intraoral scanner CS3500 on winsix implantsand the two performed by Trios3 intraoral scanner 3Shapedental on Winsix implants and Geass Way implantsThe fitting accuracy of the last mesostructure made by impression performed on Geass Way implants with CS3500 scanner looks a middle way.ConclusionsThe misfit of all the mesostructures obtained by digital intraoral scanners seems to be in the safety range, avoiding structural tensions involving implant after screwing.This study confirm the fitting accuracy of milled mesostructures obtainable by digital intraoral impressions.We expected a more homogeneous results in the group of mesostructures obtained by digital impressions, poor number of mesostructures investigated may be the reason of the discrepancy.More data are indispensable to complete the results obtained and to investigate the real accuracy obtainable .
Book Synopsis A Comparison of Digital Intraoral Scanners and Alginate Impressions: Time & Patient Satisfaction by : Jennifer Ann Burzynski
Download or read book A Comparison of Digital Intraoral Scanners and Alginate Impressions: Time & Patient Satisfaction written by Jennifer Ann Burzynski and published by . This book was released on 2017 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Impressions play an important role in dentistry and its specialties. Recent technological advances have made intraoral scans and digital models a possibility, and a promising alternative to conventional alginate impressions. Several factors should be examined when considering an intraoral scanner, including patient acceptance and efficiency. The objectives of this study were to assess and compare patient satisfaction and time required among two intraoral scanners and conventional alginate impressions. Methods: An initial pilot study was completed to create a valid and reliable survey instrument which would measure three areas of patient satisfaction with the impression experience. Following the survey development, the questionnaire was administered to orthodontic patients receiving one of three types of impressions, and the time required to obtain the impressions was recorded. Results: Reliability was evaluated with ICC values for 17 paired questionnaires, and all questions were found to be reliable (ICC = 0.65). For the main study, 180 subjects completed timed impressions and surveys. Data indicated that subjects receiving intraoral scans preferred the digital impressions while subjects receiving alginate impressions were neutral regarding impression preference, and that efficiency varied based on impression method. Conclusions: Intraoral scanners are accepted by orthodontic patients, and they have comparable efficiency to conventional impression methods depending on type of scanner.
