With the rapid progression of additive manufacturing and the emergence of new 3D printing technologies, accuracy assessment is mostly being performed on isosymmetric-shaped test bodies. However, the accuracy of anatomic models can vary. The dimensional accuracy of root mean square values in terms of trueness and precision of 50 mandibular replicas, printed with five common printing technologies, were evaluated. The highest trueness was found for the selective laser sintering printer (0.11 ± 0.016 mm), followed by a binder jetting printer (0.14 ± 0.02 mm), and a fused filament fabrication printer (0.16 ± 0.009 mm). However, highest precision was identified for the fused filament fabrication printer (0.05 ± 0.005 mm) whereas other printers had marginally lower values. Despite the statistically significance (p < 0.001), these differences can be considered clinically insignificant. These findings demonstrate that all 3D printing technologies create models with satisfactory dimensional accuracy for surgical use. Since satisfactory results in terms of accuracy can be reached with most technologies, the choice should be more strongly based on the printing materials, the intended use, and the overall budget. The simplest printing technology (fused filament fabrication) always scored high and thus is a reliable choice for most purposes. therefore apply to different fields of medicine and dentistry. With the continuous development of each individual technology, none stand out significantly from the others and so all are represented in the daily medical routine.Even though AM was introduced into medicine many years ago, the production of anatomical models often is still one of the main areas of application [3][4][5][6]. In opinion polls, surgeons still tend to regard anatomical models as advantageous for daily work [7]. For instance, anatomical models offer numerous advantages over other learning resources in understanding complex anatomical correlations [8]. The combination of optical and tactile sensitivity leads to a superior understanding and has defined the concept "touch to comprehend" [9]. A meta-analysis of 158 studies from 2005 to 2015 described further advantages such as possibilities for preoperative planning and time savings in the operating room, but emphasized that accuracy was not satisfactory in 34 studies [10]. Although most manufacturers provide the specifications in terms of accuracy, these are mostly uncertain in the final clinical application. In addition, most tests are performed on isosymmetric-shaped bodies [11], but the use of anatomical models may reveal larger dimensional errors. Measurements with skull and mandibular models revealed incorrect or completely missing anatomy [12]. Even deformations of 3D printed dental surgical guides were reported [13]. Inaccuracies in 3D printing applications can lead to inappropriate treatment that could harm the patient.Identical procedures with the same material under the same circumstances do not necessary lead to identical results.

“…Cost and size of 3D printers have rapidly decreased over the past decade in parallel with the expiration of key 3D printing patents, allowing its use in dental and medical practice . From a clinical point of view, indications are as varied as the creation of low‐cost personalized prostheses, biocompatible implants, and bioprinting . There are numerous initiatives in the field of dental and medical education, mainly to understand normal anatomy or for surgical simulation .…”

A low‐cost 3D printed model has been introduced into the oral and maxillofacial surgery teaching program of undergraduate students to improve education and mechanical comprehension of craniofacial trauma. Steps of the 3D printed haptic model building process are listed. 3D printed models of facial fractures were obtained from Data Imaging and Communications in Medicine (DICOM) data. Computed Aided Design and Manufacturing (CAD‐CAM) freeware was used to create new fractures on the standard tessellation language (STL) file. 3D printed haptic model appears to be an efficient low‐cost support for craniofacial trauma education of undergraduate students.

“…Advanced manufacturing or 3D printing has already made inroads in maxillofacial reconstruction 17 but bioprinting approaches are still largely investigated at the research level 18 . Due to its unique and complex contours which are critical for the aesthetic appearance, the human auricle has been a favorite target for 3D printing 141 .…”

ZusammenfassungDie Regeneration als therapeutisches Prinzip und damit die Regenerative Medizin ist ein vielversprechender Ansatz künftig die therapeutischen Optionen der Hals-Nasen-Ohrenheilkunde um eine weitere Dimension zu erweitern. Während heute rekonstruktive chirurgische Verfahren, Medikamente und Prothesen wie bspw. das Cochlea Implantat die Funktionen defekter Gewebe im Kopf-Hals-Bereich ersetzen, sollen durch die Regenerative Medizin die defekten Gewebe und deren Funktion selbst wiederhergestellt werden. In dieser Übersichtsarbeit werden neue Entwicklungen wie das 3D-Bioprinting und dezellularisierte, natürliche Biomaterialien für regenerative Ansätze vorgestellt und durch eine Zusammenstellung aktueller präklinischer und klinischer Studien im Bereich der Regenerativen Medizin in der Hals-Nasen-Ohrenheilkunde ergänzt.
