Abstract

Purpose Different technologies may currently be used to produce dental prostheses, such as additive manufacturing and traditional milling. This study aims to evaluate and improve the fabrication process for hot-pressed porcelain dental prostheses and compare the use of masked stereolithography apparatus (MSLA) casting to computer-aided design/computer-aided manufacturing (CAD/CAM) casting. The cost-benefit analysis of producing dental prostheses through various technologies, including additive manufacturing and traditional milling, has not been fully explored. The cost of materials and processes used to produce prostheses varies based on complexity of design and materials used, and long-term effects, such as durability and wear and tear, must be taken into account. Design/methodology/approach Using key elements of part costs and estimation cost models, a multivariable approach was used to evaluate the practicality of the recommended strategy and process improvement. Findings The research found that MSLA casting provides a higher return on investment than CAD/CAM casting, and the optimized production process could be more suitable for the size and annual demand for prostheses. Originality/value Overall, this study highlights the need for a more comprehensive understanding of the cost-benefit analysis of different dental prosthesis production methods and emphasises the importance of evaluating long-term effects on the cost-benefit analysis.
MSLA应用于热压烤瓷义齿生产的研究与优化
目前可以使用不同的技术来生产义齿,例如增材制造和传统铣削。本研究旨在评估和改进热压烤瓷义齿的制造工艺,并将掩模立体光刻设备(MSLA)铸造与计算机辅助设计/计算机辅助制造(CAD/CAM)铸造进行比较。通过各种技术(包括增材制造和传统铣削)生产牙修复体的成本效益分析尚未得到充分探索。用于生产假肢的材料和工艺的成本因设计和所用材料的复杂性而异,并且必须考虑到长期影响,例如耐用性和磨损。设计/方法/方法使用零件成本和估算成本模型的关键要素,采用多变量方法来评估推荐策略和流程改进的实用性。研究发现,MSLA铸造比CAD/CAM铸造具有更高的投资回报率,优化后的生产工艺更适合义肢的尺寸和年需求量。总体而言,本研究强调需要更全面地了解不同义齿生产方法的成本效益分析,并强调评估成本效益分析的长期影响的重要性。

期刊介绍: Rapid Prototyping Journal concentrates on development in a manufacturing environment but covers applications in other areas, such as medicine and construction. All papers published in this field are scattered over a wide range of international publications, none of which actually specializes in this particular discipline, this journal is a vital resource for anyone involved in additive manufacturing. It draws together important refereed papers on all aspects of AM from distinguished sources all over the world, to give a truly international perspective on this dynamic and exciting area. -Benchmarking – certification and qualification in AM- Mass customisation in AM- Design for AM- Materials aspects- Reviews of processes/applications- CAD and other software aspects- Enhancement of existing processes- Integration with design process- Management implications- New AM processes- Novel applications of AM parts- AM for tooling- Medical applications- Reverse engineering in relation to AM- Additive & Subtractive hybrid manufacturing- Industrialisation
