“…We then work with a drilling guide and another exactly the same but where the only thing that varies is the tube. Advances in the precision of 3D printing allow both guides to be sleeveless, as they are unnecessary for both drilling and inserting the implants [19][20][21].…”

“…After printing, the model was processed by removing support, polishing, and smoothing. SLA laser curing layer printing was adopted in concave models printing, the material was transparent resin, the printing resolution was 0.01mm, and the molding speed was 100g/h[ 20 , 21 ].…”

“…The most important role of the convex model is to measure and to reflect the external contour of the infant’s airway for research purposes. Using FDM printing helps save money and printing time[ 20 , 21 ]. Nevertheless, SLA printing with highly transparent photosensitive resin is used in the concave models to enable a more direct view of the blocking state of the new-style BB inside the airway and to assess the sealing effect.…”

It is technically challenging for pediatric anesthesiologists to use bronchial blocker (BB) to isolate the lungs of infants during thoracoscopic surgery. Further, BB currently sold in the market cannot match the anatomical characteristics of the infants, especially on the right main bronchus. It may easily cause poor exhaustion of the right upper lobe, which leads to interference with the thoracoscopic surgical field. The two dimensional reconstruction data of 124 normal infants’ airways were extracted from the medical image database of Beijing Children’s Hospital for statistical analysis. After using linear fitting and goodness-of-fit test, a good linear relationship was detected between infant age and various parameters related to aid in designing a new BB for infants (R2=0.502). According to the growth and development rate of infants, the DICOM files of airway CT scan of 7 infants aged 30, 60, 90, 120, 180, 270, and 360 days were selected to print non-transparent convex and transparent concave 3D models. The non-transparent convex model was precisely measured to obtain the important parameters for BB design infants only, to complete the design of BB, to generate the sample, and to verify the blocking effect of produced sample in transparent concave three-dimensional (3D) model.

“…3.1 Applications of additive manufacturing in the surgical stage of implant treatment 3.1.1 Surgical guides 3D printed surgical guides have been used for more than 10 years, and the digital workflow of the guides is as follows. Virtual planning and design is conducted using computer software and digital workflows for planning and manufacturing, based on data obtained from 3D imaging, and these plans are then transmitted through 3D printed surgical guides (Rouzé L'Alzit et al, 2022;Unsal et al, 2020;Zhang et al, 2020). At present, SLA is the most widely used approach, due its economical nature and speed.…”

“…The production of guides involves multiple, closely-linked steps, including data collection and integration, design of the implanting plan and guide structure, and manufacturing, and errors in previous steps will accumulate in the final guides (Putra et al, 2022;Rouzé L'Alzit et al, 2022). Factors influencing template accuracy can be roughly divided into three categories: 1) System error: that is, errors generated during CBCT scanning and data conversion, which cannot be controlled by humans; 2) Manufacturing error: related to the type of 3D printer (Zhang et al, 2022) (Table 1), selection of printing materials, use of supporting structures, slicing method and software types (Cho et al, 2021;Elliott et al, 2022;Rubayo, et al, 2021); and 3) Other factors.…”

Additive manufacturing (AM) technologies can enable the direct fabrication of customized physical objects with complex shapes, based on computer-aided design models. This technology is changing the digital manufacturing industry and has become a subject of considerable interest in digital implant dentistry. Personalized dentistry implant treatments for individual patients can be achieved through Additive manufacturing. Herein, we review the applications of Additive manufacturing technologies in oral implantology, including implant surgery, and implant and restoration products, such as surgical guides for implantation, custom titanium meshes for bone augmentation, personalized or non-personalized dental implants, custom trays, implant casts, and implant-support frameworks, among others. In addition, this review also focuses on Additive manufacturing technologies commonly used in oral implantology. Stereolithography, digital light processing, and fused deposition modeling are often used to construct surgical guides and implant casts, whereas direct metal laser sintering, selective laser melting, and electron beam melting can be applied to fabricate dental implants, personalized titanium meshes, and denture frameworks. Moreover, it is sometimes required to combine Additive manufacturing technology with milling and other cutting and finishing techniques to ensure that the product is suitable for its final application.
