The purpose of this study is to evaluate whether additive manufactory technology through the use of 3D mandible and skull cast models can provide additional support to the virtual surgical planning for patients affected by unilateral condylar hyperplasia (UCH). This study describes 2 patients affected by active UCH. Cone beam computed tomography (CBCT) scans were converted in STL files and then sent to a 3D printer that provided 3D cast models of patient’s mandible and skull. Surgical planning was conducted performing linear measurement both on 3D virtual images and on 3D cast models. Proportional condylectomy was then simulated with the virtual software and on the 3D cast models as well. After 18 months, new CBCT scans of the patients were acquired and new 3D cast models were printed. Measurements performed on the 3D cast models were close and reliable if compared to measurements obtained on 3D virtual images. None of the patients underwent further surgeries obtaining stable results in terms of symmetry. 3D printing technologies have a relevant support for a more accurate planning and surgical treatment in UCH.

Abstract

The purpose of this study is to evaluate whether additive manufactory technology through the use of 3D mandible and skull cast models can provide additional support to the virtual surgical planning for patients affected by unilateral condylar hyperplasia (UCH). This study describes 2 patients affected by active UCH. Cone beam computed tomography (CBCT) scans were converted in STL files and then sent to a 3D printer that provided 3D cast models of patient’s mandible and skull. Surgical planning was conducted performing linear measurement both on 3D virtual images and on 3D cast models. Proportional condylectomy was then simulated with the virtual software and on the 3D cast models as well. After 18 months, new CBCT scans of the patients were acquired and new 3D cast models were printed. Measurements performed on the 3D cast models were close and reliable if compared to measurements obtained on 3D virtual images. None of the patients underwent further surgeries obtaining stable results in terms of symmetry. 3D printing technologies have a relevant support for a more accurate planning and surgical treatment in UCH.
