Special Issue Information

Dear Colleagues,

Additive manufacturing, defined by the American Society of Testing and Materials (ASTM) as “the process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies”, is a versatile technology with wide-ranging applications in the medical and dental fields.

The customization possibility in obtaining complex geometries, the great number of dental materials used (polymers, metals, ceramics) and various manufacturing technologies such as vat-polymerization, material jetting, material extrusion, binder jetting, powder-based fusion, sheet lamination, and direct energy deposition, have extended the use of additive manufacturing for experimental, clinical and educational purpose.

This Special Issue will focus on the use of additive manufacturing in various fields of dentistry, oral and maxillofacial surgery and maxillofacial prosthodontics.

There are many questions requiring updated answers in this field. Some examples include the following: What are the last developments and the materials used with additive manufacturing technologies? How to improve the accuracy of 3D printed surgical guides used for dental implants insertion or in orthognathic surgery? What are the latest developments in dental ceramic structures fabrication using 3D printing? What are the latest developments in materials and technologies in maxillofacial prosthodontics? How could bioprinting technology improve bone or soft tissue reconstruction? Could 4D printing and smart materials fulfill the biomechanical requirements in dental field?

Original research studies, reviews, short reports and case reports on this topic are welcomed.

Background: With CAD-CAM, dental models are often fabricated by additive manufacturing (AM) methods. Dental models for implant prostheses involve the manual placement of analogs, which could affect their final fit. Therefore, in this experimental in vitro study, the accuracy of the analogs’ position in models printed using AM methods was examined by comparing three different printing orientations. Methods: An STL file was obtained by scanning a master model with an implant placed in the maxillary left central incisor position. Three study groups (n = 10) with varying printing orientation parameters were obtained (0, 45, and 90 degrees). They were digitalized with a laboratory scanner and evaluated with an analysis metrology program. Differences between 3D datasets were measured using the RMS for trueness and SD RMS for precision. The data were statistically analyzed using the ANOVA test at a significance level of p < 0.05, followed by the Bonferroni post hoc test. Results: The 45-degrees group showed the best results. Regarding trueness, statistically significant differences were found between the 45- and 90-degrees groups (p < 0.005). In terms of precision, statistically significant differences appeared between the 45- and 0-degrees groups (p < 0.011) and between the 45- and 90-degrees groups (0.003). Conclusions: The printing angulation parameter affects the accuracy of 3D-printed models. Implant models manufactured at 45 degrees of printing angulation are more accurate than those printed at 0 or 90 degrees. Full article
