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.
Dental implant materials are advancing in the fusion of various scientific fields. Surface modification technologies for implants have been applied to titanium at the micro-level for about four decades. Now, implant surfaces are being topographically and chemically modified at both the micro- and nano-level. The modification techniques are altering other metals and ceramics, making these materials more biocompatible. Materials for abutments in dental implant systems appear to depend on implant–abutment connection structures. Biomechanical factors, such as friction and preload, influence the development of the abutment materials. Additionally, the surfaces of the abutment materials are important in the soft-tissue attachment, which is being actively investigated. As dental implants have to be functional in human bodies for a long time, numerous materials are being clinically tested as implant-supported restorations. The Special Issue, “Dental Implant Materials 2019”, introduces the creative works of scientists on the current advancements in the field of materials for implant dentistry.
Biointegration is essential for the successful performance of implanted materials and devices within the human body. With an increasing number and wide range of implant procedures being performed, it is critical that materials scientists and engineers effectively design implant materials which will create a positive biological and mechanical response with the host tissue. Biointegration of medical implant materials provides a unique and comprehensive review of recent techniques and research into material and tissue interaction and integration. Part one discusses soft tissue biointegration with chapters on the biocompatibility of engineered stem cells, corneal tissue engineering and vascular grafts. Part two then reviews particular techniques in drug delivery including inorganic nanoparticles for targeted drug delivery and alginate based drug delivery devices. Part three covers design considerations with coverage of themes such as biocompatibility of materials and its relevance to drug delivery and tissue engineering, mechanisms of failure of medical implants during long term use and rapid prototyping in biomedical engineering. With its distinguished editor and team of international contributors, Biointegration of medical implant materials: science and design is a standard reference for medical materials scientists and engineers in industry and the academic sector. Provides a unique and comprehensive review of recent techniques and research into material and tissue interaction and integration Discusses soft tissue biointegration with chapters on the biocompatibility of engineered stem cells, corneal tissue engineering, vascular grafts and replacement materials for facial reconstruction Reviews particular techniques in drug delivery featuring inorganic nanoparticles and functionalized nanoparticles for targeted drug delivery

Background: Implant treatment is highly influenced by marginal bone (MB) stability that is usually thought to be influenced by occlusal load application and/or peri-implant inflammation. However, the sole effect of abutmentpreload installation on MB around implant had not been studied yet. The contact force that bring the abutment and implant clamped together is called preload, which is a tensile force . A finite element analysis wasconducted and revealed the existence of preload stress distributed in MB.Aim: The purpose was to investigate histological MB alternations around osseointegrated dental implants caused by abutment screw preload using recommended and high tightening torque values in-vivo.Materials and Methods: Sixteen Japanese white male rabbits were used. Each animal received two implants in each right and left femur. After eight weeks, test and control implants were randomly selected. A 35Ncm torque was applied totighten abutment screws (n=16) as recommended preload group (RP). Other abutment screws (n=16) were subjected to 70Ncm tightening torque as high preload group (HP). Tightening group (HT) received only 70Ncm tightening torque withoutpreload (n=8) as screw was untightened immediately. Control group (Cont) implants remained in-situ (n=24). Animals were sacrificed at 4, 6, 8, 10weeks after abutment screw attachment. MicroCT images were taken, undecalcified groundsections were prepared, stained with Toluidine Blue and investigated under light microscope and polarized light. Bone volume fracture (BVF), bone-to-implant contact (BIC), and bone area (BA) were calculated and two-way ANOVA test wasperformed as statistical analysis. The ethical approval obtained as No.28-189-2 Niigata Uni.Results: Cross sections of cortical bone showed bone remodeling activities adjacent to the implants in all specimens of all groups. While bone marrow spaces were relatively small in Cont and HT groups, RP and HP groups showed larger areaof bone marrow spaces especially after 10 weeks. Those spaces were defined as Bone Multicellular Units (BMUs), which is responsible for cortical bone remodeling activities. Moreover, lamellar bone thickness appeared to be larger in Cont andHT groups compared to RP and HP groups. Under polarized light, lamellar bone in Cont and HT groups displayed alignments of orderly homogeneous collagen fibers perpendicular to the implant axial plane. In contrast, predominant transverseor alternated collagen fibers appeared in RP and HP groups. BIC was significantly lower in RP and HP groups compared to Cont groups at 6, 8, 10 weeks (Pu02c20.05). Furthermore, RP and HP groups showed significantly less BVF and BAcompared to other groups especially at 8 and 10 weeks (Pu02c20.05).Conclusion and Clinical Implications: The findings indicated the possible transfer of preload stress from the implant-abutment joint to the surrounding MB even without occlusal loading. This study demonstrated active bone remodeling,appearance of BMUs in the interested area and decrease of BIC in response to preload. We may have to take the finding into consideration upon abutment screw tightening. Needs for further in-vivo investigations for optimal torque of screwtightening and initiation of occlusal load application were raised.

This valuable book presents clinical experiences and research of bone grafting. Bone grafting is an essential technique practiced by craniofacial, maxillofacial, orthopedic, neuro, reconstructive and oral surgeons. Bone grafting can be used for reconstruction and restoring missing bone in trauma and tumor surgery of the facial bone or in road traffic accidents with multiple injuries and in post-traumatic missile war injuries to the face or limbs. Bone grafts, in the form of Kummoona Chondro-Ossous graft or Costo-Chondral graft, are used for reconstruction of damage TMJ for restoration of growth, function, and repair. Bone grafting is a surgical procedure where the iliac crest or rib or tibia is used to perform grafting. In this book, we examine the experimental studies on rabbits to understand the cellular changes associated with bone grafting. From this, we noticed that mesenchymal stem cells and growth factor are released from platelets and these play an important role in healing the bone graft. We recommend this valuable book to all cranio-maxillofacial, orthopedic, plastic, reconstructive, neuro and oral surgeons and to all postgraduate students studying bone grafting.
