Book excerpt: Objective: In recent years, immediate loading implant treatment has been widely recognized as an effective solution for edentulous patients. Risk factors of disintegration associated with immediate loading include excessive occlusal force such as bruxism, and relating to the technical complication, the fracture of temporary restoration has been pointed out. The fracture of temporary restoration can be considered to increase the micro movement around implant, and lead to fail osseointegration. A large numbers of stress analysis for implant prosthesis has been reported by 3D FEA and mechanical tests, but it has not been clarified the cause of fracture of the temporary restoration in multidimensional analysis. In this study, we analyzed the stress concentration in patient models by 3D FEA and the cyclic fatigue test in materials for temporary restoration, and tried out the combination stress analysis. Subjects and Methods: The strength to be possessed as a temporary prosthesis was examined by 1) the stress test, 2) the three-point bending test and 3) the three-dimensional finite element analysis (FEA). 1) For the 100000 cyclic fatigue test, a test piece of 25 mm in length u00d7 10 mm in width u00d7 2 mm in thickness cut out from a resin disc for CAD/CAM (Aadva PMMA disc, GC Co.) was used. 2) For the three-point bending test, a similar test piece to the one used in the stress test was used. 3) For the FEA, the results of the three-point bending test was reproduced and analyzed. Test pieces were similar condition. 4) To recognize the clinical situation, another FEA was done with the immediate load patient model. These models were maxillary edentulous patients before implant placement. To assume immediate load, the inter-face between the bone and the implant was set as a u201ccontact stateu201d (frictional coefficient = 0.33). The physical property values of the bone were calculated from the CT values and set for each element, and the physical property values of other elements were set based on the known values. The load condition was set based on the occlusal force data recorded from a patient with bruxism, and the constraint condition was set as the maxillary sinus upper margin. This study was approved by the ethics committee of our school of dentistry and the data was used with the patientu2019s consent.Results: From the 105 cyclic fatigue test, it is revealed that the PMMA piece was fractured over 115 N load. In the three-point bending test, the average maximum tensile stress in the test piece was 80.3 MPa at 115 N load, that of FEA analysis was 75.5 MPa at the same condition. In the FEA patient models, the maximum tensile stress over 75.5 MPa was found at the PMMA material around temporary cylinder, and maximum value were 247.7 MPa, 258.8 MPa and 290.8MPa for each patient.Discussion and Conclusion: The fracture of temporary restoration in immediate loading treatment is estimated to occur around temporary cylinders. It is necessary to consider temporary restoration designs or reinforcement not to exceed the maximum tensile stress in real clinical situation. From the results of this study, it is suggested that the effective possibility of combination stress analysis in real material and FEA model.

This book was released on 2009 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to investigate the fatigue life of an endosseous root-form dental implant using finite element analysis. A conventional Brånemark dental implant system was redesigned to utilize the biocompatible, lightweight magnesium alloy coating which promotes bone growth. ANSYS Workbench 11.0 was used to generate a three-dimensional mesh of a model created in Pro Engineer with the actual size specifications. Regulations and schematic of test set-up from ISO 14801 - "Fatigue test for endosseous dental implants" were strictly followed to simulate the fatigue test. To validate the credibility of calculated fatigue life, actual prototypes were built with the design specifications and tested using Material Test System 810. The main advantages of performed computer simulations are that it is fast, efficient and cheap. A comparison of the calculated fatigue life with experimental fatigue life data displayed the accuracy and reliability of the computer simulation method.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Development of an ideal substitute for missing teeth has been a major aim of dental practitioners for millennia. Modern dental implants are biocompatible screw-like titanium {u2018}fixtures{u2019} that are surgically placed into the jaws to replace missing teeth. Implants are superior to conventional prostheses, in both function and long-term predictability. In 2006 approximately 30,000 implants were placed in Australian patients. Implant sales have doubled in the last 5 years and are increasing by about 15% per year. Although implants exhibit excellent long-term retention (~95% after 5 years), there are significantly more failures in areas where bone quality and quantity is poor, resulting in poor patient outcomes and costs estimated at $15 million per year in Australia. Most failures arise from poor clinical technique and inadequate understanding of the potentially damaging stress characteristics during implant placement and function (chewing). Three-dimensional (3D) Finite Element Analysis (FEA) is a numerical method for analysing stresses and deformations in structures of any given geometry and under any load. There are reports on utilising 3D FEA to investigate implant-jawbone interactions after full osseointegration. However no work has been done to comprehensively quantify the performance of the bone-implant system during and after implantation. This research thus aims to develop a comprehensive FEA technique to evaluate the performance of the bone-implant system during the implantation process itself, as well as the healing and maintenance phases of osseointegration.

Available in PDF, EPUB and Kindle. Book excerpt: This atlas, in which a wealth of illustrations are supported by clear explanatory text, offers an up-to-date and comprehensive overview of the immediate restoration of teeth and immediate functional loading when using different implant systems and surfaces in patients with single tooth loss or partial or complete edentulism. It provides guidance on all aspects of technique, including procedures for impression and measurement taking, and describes the surgical and prosthetic protocols applicable in various settings. The coverage encompasses the more advanced techniques used for immediate loading of implants placed in conjunction with grafting/augmentation procedures or in fresh extraction sockets, as well as immediate implant loading for mandibular and maxillary full-arch rehabilitation. This atlas will help dental students and practitioners to gain a sound understanding of immediate loading techniques, including their indications and limitations, and to apply them optimally in their practice. The atlas also shows and explains how to integrate a full digital workflow from the intraoral scanner to solve complex cases in a simple way.
