The Resistance of the Cantilever Bridge by the Use of Dual Resinous Cement

Advantages for Dental Bridges with Resin-Fixed Dental Prostheses

For the treatment of missing teeth, dental bridges with resinfixed dental prostheses have been paid an attention because it is a minimally invasive and an economical prosthetic treatment. Although dental implant replacement which is often considered to be the first option by which tooth implanted is fixed for a longterm with surgically screws into the jawbone. Resin cements build a cantilever bridge to a crown on one side of the missing tooth. (Romy, et al. [1]) have virtually estimated stress distribution of a cantilever bridges with two commercially available resins in this report. These two models of resin cements were simulated with a pontic (lateral incisor) and a palatal retainer (upper left canine) using 3D CAD software. They calculated the compressive stress distribution generalized in a cantilever bridge through finite element analysis. The compared two models, Relyx U200 cement in model A with conventional dual resinous cements, Relyx ARC cement in model B with one-bottle, self-adhesive system. The mechanical properties of two models were comparable for this study because modulus of elasticity was 6600 MPa in Relyx U200, 5100 MPa in Relyx ARC, Poisson’s ratio was 0,33 and 0,27. These data show that Relyx ARC may be a bit less deformable than Rely U200.

Exactly the Same Results; Its Evaluation

A force of 100 N was simulated on the palatal side of the pontic at 45 degrees and a horizontal force of 100 N on the palatal side of the canine. The results for both models were identical; the maximum stress was 660,891 MPa when applying oblique forces and 16.6 MPa when applying horizontal forces. The displacement of the cantilever bridge for both models also showed the same maximum value of 0.014 mm for oblique forces and 0.00066 mm for horizontal forces. Previous study showed variations in the compressive stress when resin cements with different modulus of elasticity at fixed dental prosthesis. [2] The present investigation showed the identical results in compressive stress distribution of both oblique forces (maximum value) and horizontal forces (maximum and minimum values). The author said the discrepancy may be due to retainer design, since in the present study the thickness was greater (0.8 mm) than other studies. The thickness of the material likely influenced the stress distribution. Even so, absolute the same values of maximum stress obtained at two different angles may guarantee rigid stability of Relyx resins. The author can try other resins such as Unicem 2, PANAVIA SA Plus, Speed CEM Plus, Maxcem Elite Chroma, or Calibra Universal which were known to have lesser strength to dentin after artificial ageing. [3] It may reveal that whether the use of different resinous cements influences the risk of prosthesis failure in clinical practice or not. The experiments shown here were not in vitro nor in vivo but were image analyses using 3D CAD software, so the author remarked the impossibility of simulating a real situation in the mouth by finite element analysis. I think this analysis would be a useful tool for the evaluation of the mechanical behaviour of the variety of the fixed adhesive prosthesis.

Elderly Persons Who Filled with Crown Bridge Abutment in Japan

In Japan, School Health Survey reported that 41.6% of high school students (aged 15-18 years old) had one or more carious tooth in 2020. [4] The rate was decreasing from 59.95% in 2010 possibly by a spreading of fluoride brush-in education in schools, accompanied by the improvement of students’ life habits. In Japanese adults, Survey of Dental Diseases in 2016 reported that the number of persons who filled missing teeth of maxillary left lateral incisor with crown bridge abutment were 127 out of 3,696 (3.44%) and the highest age group was 8.82 % in 85 years old or older followed by 6.58% in 75-79 years old. [5] In Japan, 65 years old or older population reached 28.8% of the total and this highest percentage is still increasing. Hereafter more persons are probably going to select the treatment of missing teeth by crown bridge abutment.

Data Warehouses, Decision Support Systems, and Deep Technologies During the Global COVID-19 Pandemic

Introduction

Data storage for businesses involves the storage of such information as stocks, raw materials, deposits, and other such information related to the daily operations of the business. The architecture of such a system needs to be aimed at data management. Data warehousing uses technologies that allow data from multiple sources to be compared and analyzed so that businesses can the consolidated data to make decisions (Simion, et al. [1]). The database is built to implement the volume and the requirements of the system and help project managers and organizational managers make decisions related to the development of the business structure or further daily operations (Simion, et al. [1]). Furthermore, database applications improve the reliability and efficiency of the user and the ability to make decisions, store, update, and get answers through reports (Simion, et al. [1]). Communication with the essential departments of the organization is facilitated by the efforts of the component dialog. The analysis highlights the structure between the data analysis and the simplest form of analysis is comparing the data with similar information. Other observations require techniques using analytical data based on mathematical theories which were developed to make correlations based on mathematical theories using products of a hypothetical nature compared with actual data (Simion, et al. [1]).

Deep Technologies

Over the past few decades, society has become overtly more data driven. With the takeover of social media, a need for learning how data and subjects relate to one another implies the need for a data processing method to consider emotion, sense, everyday practices, and the nexus between data and data technologies, Big Data, Internet of Things (IoT), and Artificial Intelligence may certainly be the future of all data transactions (Lee A [2]). Future data technologies must take all these factors into consideration and be able to process data at rates far exceeding current speeds and abilities. Parallel processing is beginning to play a key role in data interpretation. Thus, the benefit of using these technologies lies in capturing the scalar nature of data and focusing on the socio-technical processes behind data applications. It begins with a conceptualization of the Personhood of Data, which highlights exactly how distant the subject is from the data resulting in a conceptual language that then provides a method for analyzing the scalar nature of the data (Brynjolfsson Jin, et al. [3]).

Data, then, becomes a positivistic resource as the data highlights the humanity of the subject through each bit of datafied representation of humanity through the scientific representation of the subject’s world. So, with the use of deep technologies, data can be processed and analyzed and be used not only to humanize daily data activities, stresses, and emotions and sensemaking but to individualize our humanity in the surveillance of the data with separate and scientific representations of new data structures—the distant relationship of data and the embodied life represented by social media and activities only capable of being analyzed by deep technologies (Lee A [2]). The simplest form of analysis is comparing the data with similar data synthesized. In addition, information can acquire quality when using techniques of graphical representation that make these correlations, observation techniques analytical data based on mathematical theories, comparing actual data with the theoretical products of a hypothetical model, or observation techniques automatic based on data.

Big Data

The Internet of Things (IoT), Big Data, and Neural Networks are being considered as emerging networks that can comprehend complex automatic monitoring, identification, and management through a network of smart devices and parallel processing such as in a Neural network. Big Data has emerged as a viable and sustainable network that can analyze massive amounts of data from several sources including social media, sensors, attenuators, etc. to derive a sustainable decision by linking devices together and then developing consistent algorithms which can analyze, manipulate, and manage the connected systems so that a huge bulk of data can then be used for smarter decision-making and post-analysis for various reasons (Brynjolfsson Jin, et al. [3]).

IoT is a set of disparate devices connected via a common network such as Big Data analytics. The efficient use of the IoT in multiple areas has helped improve productivity and reduce errors (Brynjolfsson Jin, et al. [3]). Because smart devices are linked to the network, they can make smarter decisions and post-analysis via various purposes; in other words, the network is connected to these devices using Big Data, which improves the limited resources and management of data with those smart devices to improve power efficiency. Due to the inherent nature of Big Data, including the 7 Vs, improvements can be engaged in networking ability and various approaches in place for recovery, constrained energy, and the huge bulk of storage on the cloud. Therefore, data correlation and multiple characteristics of sensory data can be improved with the use of Big Data and deep technologies (Chu, et al. [4]).

Emerging Diseases and Deep Technologies

When using deep technologies, data scientists prefer R Studio or Python languages, however, they are limited in their speed and memory abilities. Scalability is one of the most important considerations when using machine learning models and parallel data summarizations (Al Amin, et al. [5]). Thus, a more successful computational data model can be presented using parallel data summarization because the model requires only a small amount of memory (i.e., RAM) and the algorithm works in three phases, producing a broader statistical and machine learning model which can handle datasets much bigger than the main memory. Designed with a vector-vector outer product with a C++ code to escape the bottlenecking that can happen in deep learning, this system is still faster and with a bigger memory than other parallel systems (e.g., Spark, Hive, Cassandra, etc.), which could become important in such cases as epidemiological disease tracing (Al Amin, et al. [5]).

Big Data plays a variety of important roles which critically support the world’s manufacturing, legal, financial, cybersecurity, and medical systems. Through open-source platforms like Hadoop, etc., information is shared among government and nongovernmental facilities regarding emerging diseases, predictions made through computational models, and cybersecurity underlaid for those who must shelter in place and work from home (Ahouz, et al. [6]). Johns Hopkins University Center for Systems Science and Engineering (JHU CCSE) has had the closest to actual live data as any other models with error rates at 4.71, 8.54, and 6.13%, respectively. Furthermore, these error rates were based on computational model error rates based on actual infection, death, and hospitalization rates based on data mining using Big Data analytics (Gupta, et al. [7,8]).

Conclusion

The strengths of Big Data analytics cannot be understated in this data-driven society where everything written on social media to the demographic makeup of the victims of the pandemic can be used as input into the computational model makeup for determining who may be future victims of the pandemic. According to the models predicted by JHUCCSE, a high rate of errors was unavoidable at the beginning of the pandemic. Contributing to the high error rates were the lack of knowledge about the disease, unknown diagnostics, and unknown patterns of susceptibility. However, as time has shown, knowledge of the factors surrounding the pandemic has contributed to a decrease in the error rates relative to the pandemic.
