“…In the field of maxillofacial surgery, 3D printing has been widely used in many aspects such as mandibular reconstruction, facial reconstruction, skull surgery, orthognathic surgery, and temporomandibular joint reconstruction ( Steinbacher, 2015 ; Ritschl et al, 2016 ; Louvrier et al, 2017 ; Roos et al, 2020 ). In addition to the anatomical model mentioned earlier, 3D objects increasingly served as surgery (cutting, drilling, and positioning) guides, occlusal splints, personalized implants (bone plates, bone reconstruction components, etc.…”

“… Ritschl et al (2016) performed nasal-alveolar bone molding (NAM) on patients with cleft lip and palate by 3D printing NAM guides; the postoperative effect was not significantly different from conventional techniques, although it saved time and labor. 3D printing technology can be applied in the treatment of maxillary tumors; the doctor can accurately remove the diseased tissue with the customized surgical guides and repair extensive defects using customized 3D printing prostheses, which proved to be successful both functionally and cosmetically ( Roos et al, 2020 ). Steinbacher (2015) reported a number of cases, including skull reconstruction of frontal defects realized by 3D-printed titanium mesh, 3D-printed cutting guide to assist mandible reconstruction with free fibula flap, and personalized splint to assist orthodontic surgery; all achieved satisfactory results.…”

With the rapid development of the three-dimensional (3D) printing technology in recent decades, precise and personalized manufacturing has been achieved gradually, bringing benefit to biomedical application, especially stomatology clinical practice. So far, 3D printing has been widely applied to prosthodontics, orthodontics, and maxillofacial surgery procedures, realizing accurate, efficient operation processes and promising treatment outcomes. Although the printing accuracy has improved, further exploration is still needed. Herein, we summarized the various additive manufacturing techniques and their applications in dentistry while highlighting the importance of accuracy (precision and trueness).

“…The review of upper limb prosthetics from 2017 showed that there are over 50 3D-printable devices, where the cost of materials is below $500 11 . Application of lightweight materials 12 and 3D printing methods to print the skeletal structure 13 of a hand 14 , 15 reduced the cost associated with purchasing a new prosthesis, at the same time adopting it to the individual needs of a patient.…”

The aim of this paper is to present an analytical method of calculating forces acting on the thumb, index, middle finger, and metacarpal part of a hand prosthesis in a cylindrical grip. This prehension pattern represents a common operation of grabbing and manipulating everyday life objects. The design process assumed that such a prosthesis would have 5 fully operating fingers and 18 total degrees of freedom: three for each finger including the thumb, and another three for the wrist. The assumed load was 1 kg and the diameter equaled 70 mm, representing a water bottle. The method was based on analytical mechanics and as opposed to experiments or numerical methods does not require many resources. The calculations involved solving a system with seven unknown forces using an equilibrium equation for forces and moments in all three axes. The resulting equations were presented in a matrix form and solved using MATLAB software. The validation of the method with an experiment using FSR sensors and comparing it to other reports showed differences in index and middle finger involvement. However, the total sum of forces was similar, therefore it is reasoned that the grip can be performed and the prediction was accurate for the thumb and metacarpal. When using the model, the friction coefficient must be chosen with a safe margin as it influences the grip force. The presented method can be used for other models and designs by inserting their dimensions into the equations and solving them numerically to obtain forces useful in mechatronics design.

“…Customized meshes make it possible for the surgeon to perfectly fit a specific device to a patient's defects, shortening the duration of the operation and, therefore, reducing the risk of postoperative graft infection [10]. Similarly, thanks to DMLS, it is possible to produce subperiosteal implants for fixed prosthetic rehabilitation of the posterior mandible in patients with reduced height or bone thickness who do not want to undergo regenerative bone surgical procedures [11]. Nevertheless, it is in maxillofacial surgery that the use of DMLS custom-made implants can find an ideal application, where patients who have suffered extensive damage to the jaws due to traumatic injury or cancer resection must be rehabilitated [11].…”

Direct Laser Metal Sintering (DLMS) is an additive manufacturing (AM) technique that is capable of manufacturing metal parts according to a three-dimensional (3D) design made using computer-assisted-design (CAD) software, thanks to a powerful laser beam that melts selectively micro-powder layers, one on top of the other, until the desired object is generated. With DMLS, it is now possible to fabricate custom-made titanium implants for oral and maxillofacial applications. We present the case of a 67-year-old woman diagnosed with a squamous cell carcinoma of the mandible. The patient underwent subtotal mandibular resection; conventional reconstruction procedures failed to rehabilitate the function of the mandible. A prosthesis replacing the resected mandible was designed and fabricated using a digital workflow. The extensive bone defect was rehabilitated with a prosthesis replacing the mandibular bone and supporting a morse-taper dental prosthesis. The masticatory function was reestablished.
