Three‐Dimensional printed model for preclinical training in oral radiology

Abstract

Introduction: 3D printing is experiencing significant growth in the teaching and learning process. This study aims to present a 3D printed skull model for preclinical intraoral radiographic practice.Materials and Methods: Two 3D printed mannequins were created. One mannequin used an STL file of a skull that was edited using two 3D modelling software (Meshmixer and Netfabb). The second mannequin was designed directly from a patient's segmented CBCT data and then converted into an STL file. Both mannequins were printed using fused deposition modelling (FDM) technology and polylactic acid (PLA) filament; teeth for the second mannequin were also printed using digital light processing (DLP). The printed skull bones were attached, the mandible was articulated to the articular fossa of the temporal bone, and the teeth were inserted into the alveoli. Intraoral radiographs of both mannequins were taken using a digital sensor (RVG 5100, Carestream).Results: Both 3D printed mannequins showed satisfactory radiographic appearance, allowing geometric representation of each intraoral radiographic projection, regardless of STL file origin. Anatomical structures, such as the periodontal ligament space, zygomatic process of the maxilla and intermaxillary suture, were represented. The

3D‐printed model for gingival flap surgery simulation: Development and pilot test

“…Given the relatively high prices of the commercial models available on the market, it seems that producing in-house 3D-printed models is cost-effective and has the advantage of being readily available. 20,36 The availability, low cost and adaptability of 3D printing were the main reasons for designing our own in-house educational model.…”

“…Giacomini et al 36 reported that complete 3D printing costs USD 34.00-39.00, depending on the technique used. This model was performed with fused deposition with white 'tough' polylactic acid (PLA) and cost around 15 EUR per model.…”
