Available in PDF, EPUB and Kindle. Book excerpt: The discipline of dental implantology is one of the scientific medical/dental fields that are moving dynamically very fast. Not to mention the multiple specialties involved in managing the service as well as the research production. As much as it is necessary to have books to review the basics of bone healing, cellular biology, and implant rehabilitation planning, it is very critical to have more focused books to link the dots and elevate the benchmark of success even higher, especially when facing the reality of more advanced case challenges nowadays. ''Dental Implantology and Biomaterial'' presents four main sections covering topics of clinically applied ''tips and tricks'', the reality of transmucosal implant surface, the future of ceramic implants, the revolution of implant surface treatment, and finally the application of nonautogenous graft in the treatment process. The aim is updating the practitioners, researchers, and postgraduate trainees in the field with up-to-date clinically applied topics focused on reducing the gap between research and clinical application. Doing so will not only optimize the practice but also advance it with evidence-based maneuvers and technical details.
Download or read book Basal Implantology written by Gérard M. Scortecci and published by Springer. This book was released on 2019-06-25 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual will help oral implantologists to understand the principles that underlie the use of basal implants as a means to provide simple solutions to complex and highly demanding clinical situations without the need for prior bone grafting. It will also serve as a richly illustrated practical guide to application of the technique. The book is in three parts, the first of which discusses basic principles and related themes, including osteogenesis, osseointegration, cortical anchorage stability, biomechanics, surgical techniques, and basal implant prosthodontics. Step-by-step guidance is then offered on the application of these principles, focusing on operating techniques, 3D treatment planning, transitional and final screw-secured prostheses, and postoperative follow-up. The third part of the book addresses a wide range of clinical situations that can be treated by basal implantology, with particular attention to the treatment of high, thin alveolar ridges and the atrophic maxilla and mandible and to the correction of previous implant failures, as well as complications and postimplantation neuropathies.
Download or read book A Computational Analysis of the Biomechanics of Immediately Loaded Dental Implants written by Ryan Shannon and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Stresses and strain in the bone surrounding a dental implant are of interest regarding the study of bone healing following the dental implantation procedure. Techniques for mapping strain in bone have been developed for physical experimentation, but computational methods for finding these strain maps are more desirable for their flexibility in dealing with changing physical properties, loading conditions, and geometries.This project first aims to develop a finite element model of a surgical dental implant and two adjacent teeth. Two implants from a cadaver are scanned by a micro-CT scanner and those images are used to create two models. The first is an implant for tooth 23 and the second for tooth 26. After building the model, the implant is loaded with a pressure and the resultant stress and strain in the teeth and surrounding bone are calculated using the finite element method. The effects of element size are studied. Various boundary conditions are explored. The parameters of the model are then modified to simulate various conditions including differences in the stiffness of the cortical bone, the teeth dentin, and the titanium implant. These differences in material properties arise from an interval of stiffness values in the literature for bone and teeth, and the unknown composition of the implant.The computational model is compared to a physical experiment during which the same implants were loaded by a downward force of 100 N. In the experiment, the implant-tooth complexes were scanned again after loading, and digital volume correlation methods were measured to calculate the strain [1]. The goal for this project is to evaluate the finite element method as a means for studying the mechanical effects of loaded implants in the surrounding bone. The methods developed in this project might be used in future studies of implant-bone complexes.

Download or read book Dental Implant Prosthetics E Book written by Carl E. Misch and published by Elsevier Health Sciences. This book was released on 2004-09-20 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new book focuses on dental implants used in conjunction with other prosthetic devices in the general dentist's office, designed to help the partially or completely edentulous patient recover normal function, esthetics, comfort, and speech. Step-by-step procedures guide practitioners through challenging clinical situations and assist them in refining their technique. The information in this practical, highly illustrated book reflects the latest in continued research, diagnostic tools, treatment planning, implant designs, materials, and techniques. Prosthetic devices covered in this include complete dentures, bridges, overdentures, and various dental implant systems. A comprehensive chapter covering immediate load implants teaches dentists how to provide an edentulous patient with implants the same day surgery is performed. A thorough discussion of preimplant prosthodontic considerations takes the practitioner through the vital assessment steps necessary to plan treatment. Considerations for assessing the restorability of teeth adjacent to potential implant sites include abutment size, crown-root ratio, endodontic status, root configuration, tooth position, parallelism, root surface area, caries, and periodontal status. Fixed treatment planning options for the completely edentulous mandibular arches expands treatment options available to dentists, helping them to treat more patients. Material thoroughly explores the three dimensional concept of available bone and the implant treatment options for each type of bone anatomy, which enables practitioners to treat patients at any stage of edentulism. Comparisons of the periodontal indices for a natural tooth and an osteointegrated implant alert clinicians to fundamental differences in the support system. Basic biomechanics are discussed, demonstrating how these principles also relate to the scientific rationale for contemporary and future dental implant designs. A comprehensive discussion of bone density in an edentulous site explains this determining factor in treatment planning, implant design, surgical approach, healing time, and initial progressive bone loading during prosthetic reconstruction.

Available in PDF, EPUB and Kindle. Book excerpt: While hip arthroplasty has become a common surgical procedure, failures still happen due to inadequate mechanical behavior of the prosthesis. This work studies the behavior of the acetabular cup (AC) implant within bone tissue and develops an impact analysis method to assess its insertion conditions. In the first part, AC insertion within bovine bone tissue are performed using reproducible mass drops. The impact force signals are recorded and are shown to be sensitive to insertion conditions of the AC implant. An empirical analytical model considering a flat punch configuration to model the bone-implant contact conditions is used to understand the variations of the signals. The AC implant tangential stability is further evaluated for different bone cavity configurations. An impact signals analysis enables to assess the AC implant primary stability in vitro. In the second part, a hammeris instrumented with a force sensor and is used to record the impacts force signals. The impact signals analysis allows to evaluate the AC implant stability. In order to transfer the approach to a situation closer to the clinical application, tests are then realized with cadaveric hips. The method is found useful to predict the AC implant stability ex vivo. In the third part, finite element models are developed to improve the understanding of the AC implant mechanical behavior within bone tissue. A model investigates the dynamic processes occurring during the AC implant impaction. The impact signals analysis allows to evaluate the bone implant contact area. A second model studies the influence of the peri-implant anisotropic bone mechanical properties on the mechanical behavior of the AC implant. By coupling experimental and numerical approaches, this work provides new features concerning the mechanical processes responsible for the AC implant stability. Moreover, the feasibility of a medical device that could assess peroperatively the AC implant stability is proved.

Download or read book Biomechanical Evaluation of Abutment Stability written by Haibo Wen and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tapered Screw-Ventu00ae (TSVu00ae) implant system features the Platform Plusu2122 Technology designed with a proprietary Friction-Fit connection that reduces micromotion and shields crestal bone from concentrated occlusal forces. Aftermarket restorative components, or those which are not designed and manufactured by the original-equipment-manufacturer, are sometimes used in conjunction with implants such as TSV in an attempt to reduce cost. Complications can arise from reverse engineering dental implant connections due to their tight tolerance schemes and precise manufacturing processes. A seemingly minor mismatch between implants and abutments may decrease mechanical stability and ultimately lead to implant failure. Quantifying abutment stability directly is challenging due to the relatively small displacements and the presence of flexure during mechanical loading. Further, high-cycle fatigue testing can be expensive and time consuming. The present study sought to quantify abutment stability using a variety of techniques and then correlate the findings with fatigue results and cross-section analysis. The results demonstrate that aftermarket abutments have compromised implant engagement which leads to a significant decrease in stability and fatigue strength.
Download or read book In Search of an Improved Methodology for Measuring Dental Implant Stability written by Naseeba Khouja and published by . This book was released on 2017 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the importance of the need for measuring dental implant stability, an effective, reliable methodology has eluded researchers, with current methods used to detect implant stability either in the early stages or incapable of providing a complete picture. This study sought to identify a parameter capable of measuring dental implant stability, to allow for the successful detection of failing implants. Through the combined use of experimental modal analysis (EMA) and finite element analysis (FEA), we examined the accuracy and reliability of three implant stability devices--the Osstell ISQ®, the Periotest®, and the Periometer--by calibrating them via both EMA and FEA, using models of dental implants of various lengths in Sawbones® of different densities. The theoretical mechanics used to operate the three devices were analyzed to understand their assumptions and limitations. To estimate angular stiffness, we employed implant models of various lengths and widths in Sawbones® of different densities. To gauge how effectively Sawbones® and porcine bones could represent human bones, different types of bone models (i.e., porcine bone, human mandibular bone, and Sawbones®) were compared using the Osstell ISQ® and the Periotest® devices, and EMA, in addition to measuring apparent bone density. Micro-computed tomography (micro-CT) was used to estimate bone mineral density (BMD) and morphometric parameters of both porcine and human bone samples. After demonstrating that the three above-mentioned devices were deficient both theoretically and experimentally, we developed an optimal model for implant stability testing through the combined use of EMA and FEA. Natural frequency, although a robust and consistent measurement, does not equate with dental implant stability. Porcine bone may overestimate implant stability measurements when applied to human bones. Sawbones® may provide reasonably good models but should be used with caution. Boundary conditions and experimental setup play an important role in the outcome of research and should be taken into consideration. The angular stiffness coefficient--which is independent of the type of abutment used--was found to represent a superior index for quantification of dental implant stability, successfully differentiating stability of implants of both varying lengths and diameters, while the other methods tested did not.
