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.

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 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background;Slight offset of the central implant in 3-unit implant-supported prostheses has been recommended to improve biomechanical behavior.However, studies that assessed the effects of an offset implant congfiguration in the posterior mandible are rare.Aim/Hypothesis;The purpose of this 3-dimensional (3D) finite element study was to assess the effects of load direction and number of implant in 3-unitimplant-supported prostheses with varying implant positions (straight-line or offset) on the stress distribution in the implant,prosthesis, and bone tissue.Materials and Methods;Three 3D models were used to simulate a posterior mandible bone block: 2 implants and 3-unit fixed dental prosthesis(FDP) with apontic in the middle (model M1), 2 implants and 3-unit FDP with a cantilever pontic at one end (model M2), FDP supported by 3implant with straight line placement (model M3) and FDP supported by 3 implant with staggered implant configuration (model M4).The applied forces were 120 N axially (L1), or 120 N obliquely(L2). The type of implant platform simulated was an external hexagon.Maximum von Mises stress (VMS) on the fixture, abutment, screws, fixed prosthesis and supporting alveolar bone was measured andanalyzed.Results;Peak VMS in the implants by oblique loading were 10-25 times greater in implant and 6-12 times greater in alveolar bone,respectively than the stresses by axial loading.Compared to the maximum stress value of the implant by oblique loading in model M1, the maximum stress value increased to 116%in M2, but decreased to 74% and 71% in M3 and M4, respectively.In the cantilevered M2 model, the maximum stress values in the FDP were 851.5 and 908.4 MPa, respectively, by the vertical andoblique loadings, which are 5.1 and 7.1 times higher than the other models, respectively.The area of maximum stress in the implant was located around the area where the abutment screw and fixture were connected.Stress concentration was observed at an abutment screw by oblique load and at the top of the implant fixture by axial load.In the supporting bone, the maximum stress value increased to 120% in M2, but decreased to 69% and 63% in M3 and M4,compared to the stress in M1 by oblique load.Conclusions and Clinical Implications;The effect of staggered alignment on implant stress was negligible, but the cantilever design of the prosthesis and the number ofimplants had a greater impact on stress distrubution.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. 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.
