Summary: The main purpose of the article is overview the advantages of rapid
technology in dental biomechanics, introduction and implementation in medical and
dental field and finally to view current and future status. In this field of science, complex
geometrical forms are ever presented and 3D data have to be processed where main
problem is how to collect data and how to design images. Rapid technology in dental
application such as restorative dentistry, implant dentistry and orthodontics will be
described as basic way in every process of additive manufacturing. However, dental
CAD/CAM systems are very important from the beginning of the process particular with
their graphical visualization and simulation. Some other details from this point of view
will be explained and general process introduction will be provided. Worldwide known
applicative software used in everyday rapid technology practice will be of great interest
offering state of the art overview in the mentioned area. Finally, an example will be
presented, with tendency to show the process for best understanding of above given
theoretically steps.
Key words: rapid technology, dental medicine, CAD/CAM technology, computer
tomography
1. INTRODUCTION
Rapid Prototyping (RP) is new technology, mostly developing in the design and
manufacturing industry. This technology provides an great opportunity to receive
physical details and the model without machining and tooling or molding manufacture,
by transforming data from CAD-system. Rapid prototyping is the automatic
construction of physical objects using additive manufacturing technology [1,2]. The first
techniques for rapid prototyping became available in the late 1980s and were used to
produce models and prototype parts, in the mechanical engineering field, in order to
evaluate the ease of assembly and manufacture of designed products ahead of actual
production. Today, they are used for a much wider range of applications and are even
used to manufacture production-quality parts in relatively small numbers. Building a
prototype is usually based on solid models from CAD-systems or models with closed

surface contours. This model is divided into thin layers in cross section with a special
software, and the thickness of each layer is equal to the resolution of the equipment on
perpendicular coordinate [2,3]. Today, there are numerous terms for rapid prototyping,
including: freeform fabrication, solid freeform fabrication, autofab, automated freeform
fabrication, digital fabrication, 3D printing, laser prototyping, layer based
manufacturing, additive manufacturing, near net-shape form freeform fabrication,
layered manufacturing, solid imaging [5]. As overview of rapid prototyping technology,
it can be mentioned following: the manufacturing of the model is taking place layer by
layer from the bottom upwards which is based on the solid CAD file, production of
highly customised products is with no need of tooling, manufacturing of real models is
using directly solid 3D CAD files, and rapid manufacturing methods can result in time
reduction compared with the conventional manufacturing methods. Prototyping is a
mandatory step in the development of any new product creating a quality prototype,
similar to the future product. The device of rapid prototyping builds a model material by
layers sequentially, one after another, until getting the complete three-dimensional
model. Thus, the time of production the model does not depend on the complexity of
the geometry, but is determined only by the size of the prototype. This is one of the
major advantages of rapid prototyping systems compared with traditional technologies
such as such as machining or casting [6]. It is also necessary to note that for the
production model from RP it is not required expensive equipment, for casting, or
building programs for CNC machine tools in CAM systems, as occurs in machining.
These advantages are especially important in the manufacture of prototypes, when it is
made single products, but not a big series [6]. Unlike traditional technologies, such as
machining or molding, all the RP systems are set for the layer additive synthesis of the
models. The beginning of every RP system is a three-dimensional solid-state computer
model of the product, created in any 3D CAD program stored in the standard STL file
format. The process of RP can be shown on figure 1 as follows:

When we talk about RP in dental medicine, the process can be shown in three
phases on figure 4, as follows.

4. CONCLUSION
This paper is supposed to show actual state in rapid prototyping technology
used in denatal biomechanics. Doubtless, the last years, modeling by computer is
widely used day-to-day practices increasing application in medicine especially in dental
biomechanics. However, as already mentioned all along in this paper, the main issue
concerns additive technology with all phases of the rapid prototyping process in dental
medicine. In conclusion, it can be said that rapid prototyping technology is very usefull
in oral and maxillo facial surgery. Every future step in RP developing will be of great
interest for dental medicine.
