Dental Crown Manufacturing using Stereolithography Method

Abstract—Dental crown by conventional methods greatly relies on the quality and accuracy of the final product which depends mostly on the technician’s subjective judgment. Also Conventional method is manually operated which involves many complex procedures, and is a time-consuming and labor-intensive job with no quantitative design and manufacturing information preserved for future retrieval. In this paper, Rapid Prototyping an additive manufacturing method is proposed for the design of custom dental crown. It is applied to modify the morphology and design of the dental crown which are able to generate a 3D object layer by layer directly from a CAD file with the most powerful and versatile RP technique known as Stereo lithography (SLA), which is opposite to that of conventional manufacturing processes. It has the highest fabrication accuracy and an increasing number of materials, which can be processed, are becoming available. This paper gives an overview regarding the conventional crown manufacturing and presents a more effective solution: the Rapid Prototyping Method which is a more sophisticated and advanced process. The proposed method provides solid evidence that computer-aided design and manufacturing technologies may become a new avenue for custom-made dental crown design, analysis, and production in the 21st century.
