History

The goal of rapid mechanical prototyping is to be able to quickly fabricate complex-shaped, 3D parts directly from computer-aided design models. The key idea of this novel technology is based upon decomposition of 3D computer models data into thin cross-sectional layers, followed by physically forming the layers and stacking them up; ?layer by layer technique.? This new method of modeling has raised many attentions in dentistry especially in the field of surgery and implantology. The purpose of this review study is to represent the historical development and various methods currently used for building dental appliances. It is also aimed to show the many benefits which can be achieved by using this new technology in various branches of dentistry
