将计算机辅助设计与计算机辅助制造（CAD/CAM）和快速成型（RP）两种义齿制作技术与传统的印模和颌关系记录技术相结合，以确定其可行性和适用性。使用硅胶模具制作上下颌无牙颌模型。在获得石膏工作模型后，制作丙烯酸基托，并按照先前确定的标准垂直和中心关系制作每个模型的咬合边缘。用导板记录上下颌关系。然后用数字扫描仪扫描咬合边缘。验证了上颌和下颌牙齿的对齐情况。每个牙弓中的牙齿通过CAM或RP制成一件或一组。然后对两种方法进行常规的上蜡和摇瓶。这些技术满足了医生在设计过程中对技术人员的需求，并为患者提供了与牙医一起参与美学设计的机会。此外，CAD/CAM和RP减少了椅子时间;然而，材料和技术需要进一步改进。CAD/CAM和RP技术似乎有希望减少椅子时间，并允许患者参与美学设计。此外，一套对齐的假牙设计可以增加丙烯酸的耐用性。
Two techological approaches for fabricating dentures; computer-aided design and computer-aided manufacturing (CAD/CAM) and rapid prototyping (RP), are combined with the conventional techniques of impression and jaw relation recording to determine their feasibility and applicability. Maxillary and mandibular edentulous jaw models were produced using silicone molds. After obtaining a gypsum working model, acrylic bases were crafted, and occlusal rims for each model were fabricated with previously determined standard vertical and centric relationships. The maxillary and mandibular relationships were recorded with guides. The occlusal rims were then scanned with a digital scanner. The alignment of the maxillary and mandibular teeth was verified. The teeth in each arch were fabricated in one piece, or set, either by CAM or RP. Conventional waxing and flasking was then performed for both methods. These techniques obviate a practitioner's need for technicians during design and provide the patient with an opportunity to participate in esthetic design with the dentist. In addition, CAD/CAM and RP reduce chair time; however, the materials and techniques need further improvements. Both CAD/CAM and RP techniques seem promising for reducing chair time and allowing the patient to participate in esthetics design. Furthermore, the one-set aligned artificial tooth design may increase the acrylic's durability.
