It is a relatively inexpensive technique and it has a significant impact on the patient’s confidence. Because of the popularity of this procedure, the scope of modern techniques is to minimize both the duration and the eventual adverse effects, such as postoperative sensitivity. A review was performed in order to compare the effectiveness between in-office conventional bleaching treatment and laser activated bleaching. Another aim of the study was to assess the dental sensitivity following these techniques. Three patients were treated using in-office conventional and diode laser-activated bleaching methods. Even though multiple studies have been concluded that the sensitivity levels are not higher using the conventional method in comparison to modern methods, the postoperative sensibility is related to the concentration and the contact time of the bleaching agent. Therefore, we concluded that laser activated bleaching is not significantly more efficient than the conventional method. However, in comparison to the latter method, the former one minimizes the duration of the procedure and decreases the number of sessions, as well as the dose of bleaching agent. Thus, it causes a lower sensitivity to the patient.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141351877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ganea, Florin Blaga","doi":"10.1117/12.3021866","DOIUrl":"https://doi.org/10.1117/12.3021866","url":null,"abstract":"The present industry faces numerous challenges in terms of delivering complex products, fast, inexpensive, on time, and with a robust quality level. To achieve these requirements, more and more companies are adopting a strategical orientation toward automation lines. The paper is describing the integration in the traceability systems of flexible systems formed of 3D visions working in synergy with robots to achieve higher levels of autonomy in industrial automation, level 4, High Level Automation, and level 5 Full Automation. This integration is representing a new wave in product inspection and automation level, bringing full transparency under the control of Total Traceability Management (TTM) and assuring new performance levels in terms of quality, flexibility and costs. The increasing complexity of the logistical supply and distribution flow is a consequence of the increased complexity of a vehicle's equipment and components. Increased complexity of the logistics and supply process in values proves that 50 years ago 90% of the vehicle was produced in factories for an OEM (Original Equipment Manufacturer) and today 90% of the vehicle is produced by other suppliers. It is no longer enough to control your own processes and guarantee quality within the OEM factories. The entire logistics chain must deliver a high level of quality, because in the end the materials and assemblies that reach the OEM line must be compliant so that they can be assembled without problems and guarantee the level of quality and safety required for the vehicle. All this must be done under the conditions of flexible production with many customers at the same time, where each vehicle on the OEM assembly lines may differ from the previous or subsequent one in terms of consistent quality and exact delivery times, all in accordance with JIT/JIS principles and in accordance with the specifications in the supply contract with the respective customer.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141351843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inspired by the Stewart-type mobile platform, the system employs this design to manipulate a laser beam in two directions. Moreover, it facilitates an optimal axial stroke, ensuring precise laser beam focusing. This paper details the comprehensive process, encompassing modeling, simulation, and experimental trials, of a compliant mechanical amplifier designed for powering an innovative laser scalpel prototype. The active tremor damping capability of the proposed system is thoroughly examined, shedding light on its potential applications in medical settings. The authors employed a mechatronic approach, integrating mathematical models, MATLAB simulations and finite element analysis (FEA). Mathematical models were utilized to capture the static deformation of the compliant mechanical structure, providing a theoretical foundation for the subsequent stages of development. MATLAB simulations were then conducted to validate and refine the theoretical models, ensuring their accuracy in representing the system's behavior under various conditions. To further enhance the robustness of the design, finite element analysis (FEA) was employed to validate the structural integrity and performance of the proposed device. This simulation tool allowed for a detailed examination of stress distribution, deformation patterns, and overall mechanical response, guiding refinements to optimize the system's functionality. Expanding upon this, the research underscores the significance of mitigating hand tremors in surgical procedures, emphasizing the practical implications of the developed device.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141350850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following this, a 3D component modal simulation results obtained prior physical measurements was performed using Ansys software, extracting eigen frequencies and modal shapes. This fundamental engineering method together with a laser vibrometer monitoring system was used to investigate structures and systems dynamic behavior, understanding vibration phenomena, extracting linear elastic mechanical proprieties through direct measurements, aiding in evaluating base line design structural integrity with the purpose of optimizing the further design. Subsequently, the resonance frequencies obtained from both EMA and FEA were input into Ansys software to perform a comparative study using the Cross Modal Assurance Criterion (CrossMac) method, revealing the level of agreement between them. The comparative analysis revealed a significant correlation between the experimentally eigen frequencies obtained based on laser vibrometer monitoring and obtained by FEA, confirming the precision and utility of the CrossMac method in anticipating the modal characteristics of the tested component. The validation carried out through this method strengthens confidence in the combined approach of EMA with laser vibrometer monitoring and FEA, highlighting the importance of this combination, for a dynamical structural deeper behavior understanding and to strive towards its continual improvement to perfection.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141354655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In close contact with the soft surrounding tissue, the surface may be functionalized in order to improve connective tissue cells adhesion while preventing bacterial penetration at the interface. Ultrafast laser processing of dental implants has demonstrated the potential to obtain unique surface features, down to the nanoscale. With this study, we introduce the possibility to generate laser-induced periodic surface structures (LIPSS) by picosecond laser processing, with periodicity of about 500 nm on large-scale surfaces, in a contamination-free approach. By changing the applied laser dose, different surface coloring of TiAl6V4 samples is obtained due to a gradual surface oxidation, as revealed by depth-profile compositional analyses. In the same time, an increase of the irradiation dose induced the formation of thicker oxide layers, the oxygen content increasing up to ten times. The response of human mesenchymal stem cells (hMSCs) in contact with laser processed surfaces was evaluated to assess samples cytocompatibility. It was demonstrated that large-scale, uniform LIPSS distributed on whole TiAl6V4 surface are beneficial to hMSCs viability and proliferation.","PeriodicalId":198425,"journal":{"name":"Other Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141350862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
