Resumen


Objective: This is a preliminary descriptive study to evaluate the dimensional accuracy of two biomodels after autoclaving. Materials and methods: Data were obtained using computed tomography (CT) scans of a dry skull, and were used as the basis for the construction of two prototypes using two rapid prototyping techniques: three-dimensional printing (3DP™) with plaster powder; and selective laser sintering (SLS) with polyamide powder. Using 19 cranial landmarks, 10 linear measurements of each prototype were repeated twenty times each using a digital caliper. After that, the SLS and 3DP™ biomodels were autoclaved under the same conditions and technical parameters. Each linear measurement was repeated 20 times after autoclaving, but only for the SLS model because the 3DP™ model deformed during autoclaving. Results and conclusion: The biomodel manufactured with polyamide powder using the SLS technique (SLS model) did not undergo any significant dimensional changes during autoclaving, which suggests that this technique may have potential clinical and surgical applicability.
