Abstract
Osseointegration is a complex process that involves the interaction of dental implants, bone, and the immune system. Preclinical testing was carried out to develop a better understanding of the mechanism. Micro-computed tomography (micro-CT) imaging techniques and immunohistochemistry are excellent tools for this objective as both enable quantitative assessment of bone microarchitecture and intercellular interaction. An extensive literature search was conducted using the databases PubMed, Science Direct, Wiley Online, Proquest and Ebscohost from January 2011 to January 2021. Among the publications retrieved, the rat model was the most frequently used experimental protocol, with the tibia being the most frequently implanted site. The region of interest demonstrates a high degree of homogeneity as measured by trabecula but varies in size and shape. The most frequently mentioned micro-CT bone parameter and immunohistochemistry bone markers were bone volume per total volume (BV/TV) and runt-related transcription factors (RUNX). Animal models, micro-CT analysis methods, and immunohistochemistry biomarkers yielded a variety of results in the studies. Understanding bone architecture and the remodeling process will aid in the selection of a viable model for a specific research topic.

Abstract
Implant surface design has evolved to meet oral rehabilitation challenges in both healthy and compromised bone. For example, to conquer the most common dental implant-related complications, peri-implantitis, and subsequent implant loss, implant surfaces have been modified to introduce desired properties to a dental implant and thus increase the implant success rate and expand their indications. Until now, a diversity of implant surface modifications, including different physical, chemical, and biological techniques, have been applied to a broad range of materials, such as titanium, zirconia, and polyether ether ketone, to achieve these goals. Ideal modifications enhance the interaction between the implant's surface and its surrounding bone which will facilitate osseointegration while minimizing the bacterial colonization to reduce the risk of biofilm formation. This review article aims to comprehensively discuss currently available implant surface modifications commonly used in implantology in terms of their impact on osseointegration and biofilm formation, which is critical for clinicians to choose the most suitable materials to improve the success and survival of implantation.

Simulation analysis of impact damage to the bone tissue surrounding a dental implant. Sci Rep 2020; 10:6927.

Abstract
Dental implant may suffer transient external impacts. To simulate the effect of impact forces on bone damage is very important for evaluation of damage and guiding treatment in clinics. In this study, an animal model was established by inserting an implant into the femoral condyle of New Zealand rabbit. Implant with good osseointegration was loaded with impact force. A three-dimensional finite element model was established based on the data of the animal model. Damage process to bone tissue was simulated with Abaqus 6.13 software combining dynamic mechanical properties of the femur. The characteristics of bone damage were analyzed by comparing the results of animal testing with numerical simulation data. After impact, cortical bone around the implant and trabecular at the bottom of the implant were prone to damage. The degree of damage correlated with the direction of loading and the magnitude of the impact. Lateral loading was most likely performed to damage cancellous bone. The stress wave formed by the impact force can damage the implant–bone interface and peri-implant trabeculae. The data from numerical simulations were consistent with data from animal experiments, highlighting the importance of a thorough examination and evaluation based on the patient’s medical history.
