Abstract
The rapid prototyping biomodels manufacturing is a recent technology with great importance in oral and maxillofacial surgery. It provides a better surgical planning, decrease of anesthesia time and great functional and esthetic results. The aim of this experimental study was to evaluate the accuracy of rapid prototyping biomodels built by three-dimensional printing (3DP) technique, since this is one of the least expensive methods available. Linear measurements of standardized bone defects and anatomic distances were compared using a digital caliper of high precision in nine dry mandibles (gold standard) and their respective biomodels. The Bland-Altman test was used for statistical analysis (5% level of significance). The results showed strong concordance between the dry mandibles and their respective biomodels, with discrepancies smaller than 2 mmin most cases (97.4%). We can conclude that the biomodels built by 3DP technique can be used for surgical planning in Dentistry.
Highlights
The increasing demand for excellence in diagnosis and treatment of the changes in bucomaxillofacial complex has become a great challenge for dental surgeons

Summary
The increasing demand for excellence in diagnosis and treatment of the changes in bucomaxillofacial complex has become a great challenge for dental surgeons. In this way, the incorporation of modern technologies in Radiology and planning advanced therapies, such as reparative and reconstructive surgery, has assumed a prominent position in the field of biotechnology. The incorporation of modern technologies in Radiology and planning advanced therapies, such as reparative and reconstructive surgery, has assumed a prominent position in the field of biotechnology One of those innovations is the rapid prototyping (RP), which uses images from computed tomography (CT) and creates three-dimensional virtual models from the CAD (Computer Aided Design) system [1]. The advantages include less surgical and sedation time, as well as a better esthetic and functional outcome, due to the possibility of previous measurement and modeling of replacement pieces in custom prototypes [5,6,7]
