Design and Analysis of Biocompatible Ceramic Dental Prostheses Using Additive Manufacturing With Digital Impression

Abstract

Abstract. Additive manufacturing (AM), also known as three-dimensional (3D) printing, has emerged as a promising technique for the fabrication of dental prostheses. It allows for the creation of complicated designs and customized solutions for individual patients to create dental prostheses (such as dental crowns, bridges, or implants). The objective of this process is to evaluate the feasibility and effectiveness of using AM technology to produce precise and biocompatible ceramic dental prostheses. AM allows for the precise fabrication of dental prostheses using layer-by-layer deposition of biocompatible ceramic materials. Utilizing this technology with digital impressions can potentially overcome the limitations, enabling the production of more accurate and customized dental prostheses. The process involves designing and analyzing the performance of dental prostheses using a specific biocompatible ceramic material suitable for AM. The design process utilizes digital impression technology to capture the geometric data of each patient's oral cavity, eliminating the need for manual impression-taking. The digital data is then used to design and fabricate the dental prosthesis using AM technology. To assess the performance and biocompatibility of the AM-produced dental prostheses, various mechanical and biological tests are conducted. Mechanical tests evaluate the prostheses' strength, durability, and fit, while biological tests assess the materials' biocompatibility in an oral environment. Various methodologies have been implemented using additive manufacturing techniques stereolithography (SLA), hybrid additive manufacturing (HAM), and vat photo-polymerization (VPP), which involves computer simulations and analysis to ensure the optimal design and fit of the ceramic dental prostheses. Computer-aided design (CAD) to create precise dental component models optimized for AM that uses the matlab version for the outcome. The prostheses produced using this method show excellent fitness, strength, and biocompatibility. The proposed strategy dominates all counterparts, accomplishing a remarkable exactness pace of 97%. Additive Manufacturing technology with digital impressions could streamline the dental prosthesis production process, reduce errors, increase accuracy, and improve patient satisfaction. The exploration provides valuable visions into the design and analysis of biocompatible ceramic dental prostheses using AM technology, paving the way for future advancements in dental prosthetic manufacturing.
