7.3.5 3D Printed Polymers for Endodontics
3D printed polymers for endodontic applications are limited and include guided
access when pulp canal obliteration is present, for autologous transplant applications, educational modeling and preoperative planning (Christofzik et al. 2018;
Liang et al. 2018) and accurate location of osteotomy perforation sites (Anderson
et al. 2018).
7.3.6 3D Printed Polymers for Teaching Models
3D simulation models derived from CBCT data sets obtained from identical physical representations of the patient’s oral anatomy are very useful, as they provide
visual and tactile information for better diagnostic, therapeutic and educational
purposes.
With this in mind, McMenamin et al. (2014) proposed the manufacture of accurate 3D printed color copies of dissected human anatomical samples to replace
human cadaver models for teaching purposes by using a combination of imaging
acquisition technology, image processing and colored 3D printing polymers. Werz
et al. (2018) also used the FDM technique to manufacture surgical training models
from common filament polymeric materials (e.g. ABS and PLA) to simulate the
anatomy of human bone for the extraction of an impacted mandibular third molar
and the maxillary sinus lift procedure. These authors indicated that 3D printing is a
promising inexpensive polymer processing method for creating training models for
residents of oral and maxillofacial surgery, as well as dental students (Werz et al.
2018). A similar conclusion was previously made by Lioufas et al. (2016) who
using magnetic resonance imaging data, created a 3D printed polymer model
for children with cleft palate deformities, for training purpose.
7.4 Improvement Characteristics of Polymeric Materials
Suitable for Additive Manufacturing in Dental Medicine
3D printed polymer composites have been improved by producers and research
groups. These materials differ in their chemical composition according to their use
as dental material and the selected processing methodology: 3D printing, conventional or subtractive procedures. However, each commercial product suitable for
clinical use is verified and approved by different organizations such as the FDA or
the European Union (EU), using standards such as ISO (13485) (Revilla-León et al.
2019). Table 7.2 shows the most outstanding results in the use of 3D printed polymer composites for their potential dental use.
