Book excerpt: Total joint arthroplasty is an effective surgical procedure for end-stage osteoarthritis of major joints with satisfactory long term clinical outcome. A large and growing number of arthroplasties are performed annually worldwide and a great number of orthopaedic surgeons are practicing arthroplasty surgery as their main surgical activity. The biological behavior of the bone-implant interface is crucial for the long term survival of the artificial joint. All factors which have a positive or negative effect on the interface are of great interest for those practicing arthroplasty surgery. Basic scientists and the industry are continuously searching for new implant fixation mechanisms and improved materials. There is an accumulation of a great amount of basic science data (both biological, material and mechanical) related to the incorporation or loosening of the bone-implant interface. However, basic science data does not always translate to satisfactory clinical application, and orthopaedic practitioners often wonder which piece of information is clinically useful. A further problem is that basic scientists often speak their own scientific language and may not fully appreciate common clinical practice needs. In this textbook the biological and mechanical mechanisms of implant incorporation and loosening will be presented. All new data concerning materials and methods for incorporation enhancement will be critically analyzed. Data useful for clinical application will be stressed. Orthopaedic Surgeons will find information which will improve their clinical practice and basic scientists will be helped to understand and appreciate clinical needs.

The contributions come from a distinguished international faculty of orthopaedic surgeons, biologists and engineers. They examine the junctional tissues between an implant and the bone in joint replacement surgery. The factors that influence junctional tissues and so affect the life-span of the implant are thoroughly discussed. These include: detailed data on the microscopy of the junctional tissues, the mechanical properties of cement, and the architecture of bone and implant design. The discussions following each contribution give meaningful insight into background information and the controversial aspects of surgical implants.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: BackgroundImplant-supported rehabilitations have become popular in last years because their high survival and success rates. Also, loading protocols have been shortened due to the development of the implant surfaces.During the provisionalitation of the implants the use of restoration with a high elastic material has been recommended to decrease the load transfer to the surrounding bone, because a load excess over the bone elastic limit could cause the implant loss due to overload. On the other hand, other in vitro studies recommended the use of higher Young u0301s modulus materials because they absorb the most part of the energy transferring less stress to the bone-implant interface.Also, splinting the implants designing splinted prosthetic structures guarantees that the maximum stress transferred to any of the implants will be lower than the load applied.This load control of implant-supported restorations is important because an excess of the stress transferred to the bone-implant interface could induce a micro motion >150u03bcm and the lost of the osseointegration.Hypothesis-Elastic materials in implant-supported restorations transfer less tension to the bone-implant interface.-Implant-supported splinted restorations transfer less tension to the bone-implant interface.-The lack of apex cortical causes more stress transmission to the bone-implant interface and higher micromotion of the implant.Materials and MethodsSix 3.5x8 Vega Klockner implants were inserted in both tibia of a New Zealand rabbit and RFA analysis was performed at this time by Penguin RFA device . An impression was carried out splinting the 3 implants with the transfer abutments to elaborate 2 identical single restorations, one of monolithic zirconia and another one of PMMA and 8 implant-supported bridges, 4 of each material with the same design. After 6 weeks of osseointegration, the animal was sacrificed and a new RFA analysis was carried out. Then, one strain gauge was stuck on the u201cbuccalu201d bone crest around each implant. Later, cement-screwed restorations were screwed at 30N to the implants and after this, a static and dynamic load of 100N was applied over the central fossa in the single restoration cases and over 3 different points when the bridges where screwed (firstly over the central fossa of one of the premolars, then over the other one and finally over the connector). Once the test was completed, all strain data were recorded. Finally, the apical cortical bone was removed and the load test was repeated in the same way.ResultsISQ mean value using multipage abutment was 62,8 (SD 10,35) in the moment of the surgery and 6 weeks after was 84,67 (SD 13,26) in the implants with the apical cortical bone (Group A) and 74.5 (SD 9,23) in the bone without apical cortical bone (Group B). Micro-strain mean value in single crowns was 103,08 u03bcstrains (SD 61,96) in group A and 471,94 u03bcstrains (SD 202,74) in group B. Micro-strain mean value in single crowns was 103,08 u03bcstrains (SD 61,96) in group A and 471,93 u03bcstrains (SD 202,74) in group B. In group A splinted crowns microstrain mean value was 57,03 u03bcstrains and in group B 202,1 u03bcstrains.Conclusions and Clinical Implications-When there is a lack of apical cortical bone ISQ values decrease. -Bone microstrains are higher when single crowns are placed and when there is an absence the apical cortical bone. -Bone microstrains are lower when the crowns are splinted and when there is a lack of the apical cortical this effect is more evident.-There is a tendency that the higher ISQ values the lower microstrain occurs at crestal level in all the cases. -When a dynamic load is applied bone microstrains are higher. -In most cases, monolithic zirconia causes higher bone microstrain.

Available in PDF, EPUB and Kindle. Book excerpt: Cementless implants have become more and more common for joint replacement anddental surgery. Initial stability is obtained during the surgery through a press fit processin the host bone, while long-term stability is obtained by bone growing around and intothe porous surface of the implant, a process called osseointegration. As debonding ofthe bone-implant interface due to aseptic loosening and insufficient osseointegration stilloccur and may have dramatic consequences, predicting implant stability and failure isone of the major goals in modern implant research.This work presents different 3D FE modeling approaches to model contact and initialand long-term stability of cementless implants using the example of a cylindrical implantand an acetabular cup implant (ACI).First, an approach to assess the initial stability of an ACI considering a realisticgeometry of a patient's hip, based on Coulomb's friction contact and standard FE, ispresented. The influence of different patient and implant-specific parameters is analyzedin order to determine optimal stability for different configurations and thus obtain theoptimal combination of the implant's surface roughness and the press-fit, based on apatient's bone quality.Second, a phenomenological model for the frictional contact behavior of debondingosseointegrated implants is developed. The classical Coulomb's law is extended froma constant to a varying friction coefficient, that models the transition from an unbroken(osseointegrated) to a broken (debonded) state, based on a state variable depending on thedeformation of the bone-implant interface. Thus, this model can account for the highertangential forces observed in osseointegrated implants compared to unbonded implants. Inaddition, a NURBS-enrichment approach for 3D contact elements is used for an efficientmodeling of the geometries and their contact. This model is applied to the torsionaldebonding of CSI and the results are compared to experimental data and to a previousanalytical model.Third, the modified Coulomb's law model is extended in normal direction consideringa cohesive zone model, to account for debonding in normal direction and allow for adhesivefriction. This model is applied to simulate secondary stability and debonding ofan ACI in different removal tests, and to determine the relevance of osseointegration andbiomechanical factors for long-term stability. The results are compared with the purelytangential model to identify the relevance of normal adhesion in the debonding of ACI.Last, two simple evolution laws for osseointegration based on initial stability is presentedto account for realistic and time-dependent osseointegration.Due to their generality, all models presented herein can be applied to all kinds of endosseousimplants or imperfectly bonded interfaces in general. Furthermore, the modelscan be coupled with remodeling algorithms or realistic loading data, to make simulationsand prognoses for the whole life cycle of an implant from the surgery, through bone remodelingand osseointegration, to long-term stability under cyclic loading.
