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 excerpt: Oggi, la presa dell'impronta digitale è una delle aree più studiate in odontoiatria, dato che lo scanner tridimensionale orale viene richiesto per diverse finalità cliniche quali protesi, su denti naturali e impianti, e ortodonzia. Tutti gli scanner orali esistenti stanno cercando di eliminare i limiti e gli svantaggi dei protocolli tradizionali, mantenendo un alto livello di precisione per poter diventare una alternativa efficace alle tecniche analogiche. Con questo libro, gli autori analizzano diversi casi clinici, sottolineando i protocolli digitali che hanno sviluppato nel corso della loro curva di apprendimento, ponendo la loro attenzione sui continui sviluppi dei materiali e delle loro caratteristiche, e sui miglioramenti quotidiani dei nuovi software. Viene anche descritto come i materiali e le tecniche tradizionali siano stati in parte sostituiti dalle nuove innovative tecnologie, e come i risultati ottenuti da queste sistematiche siano alla pari, ed in molti casi anche migliori, di quelle tradizionali.

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.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: BackgroundThe accuracy and final perfect stress free fit of the final implant restoration is dependent on various factors. But one of the most important is the creation of accurate model. The contemporary approach uses both digital and material impression taking procedures. And still there are a lot of unbeneficial factors that can alter the accuracy of final prosthesisAim/HypothesisThe purpose of the study is to evaluate the influence accuracy of three different impression taking methods for bone level implants compared to intraoral scanningMaterials and Methods38 implants were scanned using scan flags and a digital model was created using the TRIOS intraoral scanner. All the patients were divided into two groups. For group one of 20 implants were transferred using open transfers and an open stock tray impression was taken with double layer double phase C-silicon. For the other 18 implants a double layer single phase additive silicon impression was taken. For both groups was created additional 3D printed custom tray and an impression was taken with polyether. All impressions were cast with dental plaster fourth grade and were scanned with scan flags consistent with the implant system. A digital comparison was made for each group compared to the digital model, acquired from the intraoral scanning.Results Showed some significant discrepancy in the group with the wash technique and the condensational silicon, less discrepancies were found in the group with additive silicon, and almost no significant discrepancies were found in none of the implants transferred with 3D printed custom tray.Conclusion Using a 3D printed custom tray impression taking approach could be a successful alternative to intraoral scanning.

Available in PDF, EPUB and Kindle. Book excerpt: Since its introduction to dentistry, cone beam computed tomography (CBCT) has undergone a rapid evolution and considerable integration into orthodontics. However, despite the increasing popularity of CBCT and progress in applying it to clinical orthodontics, the profession has lacked a cohesive, comprehensive and objective reference that provides clinicians with the background needed to utilize this technology optimally for treating their patients. Cone Beam Computed Tomography in Orthodontics provides timely, impartial, and state-of-the-art information on the indications and protocols for CBCT imaging in orthodontics, clinical insights gained from these images, and innovations driven by these insights. As such, it is the most current and authoritative textbook on CBCT in orthodontics. Cone Beam Computed Tomography in Orthodontics is organized to progress sequentially through specific topics so as to build the knowledgebase logically in this important and rapidly evolving field. Part I provides the foundational information on CBCT technology, including radiation exposure and risks, and future evolutions in computed tomography. Part II presents the Principles and Protocols for CBCT Imaging in Orthodontics, focusing on developing evidence-based criteria for CBCT imaging, the medico-legal implications of CBCT to the professional and the protocols and integration of this technology in orthodontic practice.
