“…The optimized dentures were evenly attached to the mucosa; the uniformity was improved by 63%, and the contact pressure was decreased by 70%, thereby reducing pressure-induced mucosal pain and alveolar bone resorption. Due to the maturity of SLM technology, denture metal alloy stents can be processed to obtain a better fitness for clinical application [ 159 ]. The computer design system and AM technology can also be used to process resin-based denture bases and denture teeth ( Figure 9 ) [ 160 , 161 ].…”

In recent ten years, with the fast development of digital and engineering manufacturing technology, additive manufacturing has already been more and more widely used in the field of dentistry, from the first personalized surgical guides to the latest personalized restoration crowns and root implants. In particular, the bioprinting of teeth and tissue is of great potential to realize organ regeneration and finally improve the life quality. In this review paper, we firstly presented the workflow of additive manufacturing technology. Then, we summarized the main applications and recent research progresses of additive manufacturing in dentistry. Lastly, we sketched out some challenges and future directions of additive manufacturing technology in dentistry.

In order to effectively solve the above problems, an automatic extraction method of web text information based on network topology coincidence degree is proposed. Search engine, web crawler, and hypertext tag are used to classify web text information, and then, dimensionality reduction is carried out. After processing, the similarity of different features of web page text information is calculated, the similarity is sorted, and the similar text information is extracted according to the correlation based on segment estimation. The experimental results show that the designed method can simplify the complexity of the associated information of the data set and improve the amount of data collection and the success rate of information collection.

Purpose Additive manufacturing (AM) in prosthodontics is used as an alternative to casting or milling. Various techniques and materials are available for the additive manufacturing of the fixed and removable tooth‐supported restorations, but there is a lack of evidence on the accuracy of AM fixed implant‐supported prostheses. Recent studies investigated the accuracy of ceramic AM prostheses. Therefore, the aim of this systematic review was to evaluate the accuracy of additively manufactured metal, ceramic or polymers, and screw‐ or cement‐retained fixed implant‐supported prostheses. Materials and Methods Two calibrated investigators performed an electronic search of relevant publications in the English language following selected PICOS criteria and using a well‐defined search strategy (latest search date—1st of June, 2021). Based on the exclusion criteria (no control group, less than five samples per group, 3D printing of the implant abutment part, only subjective evaluation of accuracy, etc.) studies were not included in the review. Quantitative data of accuracy evaluation such as marginal gap, strain analysis, and linear measurements was extracted and interpreted. QUADAS‐2 tool was used to assess the risk of methodological bias of all included studies. Results Sixteen in vitro studies were selected for the final analysis. Six of the selected studies evaluated screw‐retained restorations and 10 cement‐retained implant‐supported restorations. Only 4 publications concluded that AM restorations were more accurate than conventionally made (cast or milled) ones. The most common finding was that AM restorations were more accurate than cast and demonstrated less or similar accuracy compared to milled ones (n = 10 studies). Detected marginal discrepancies mean values of the AM prosthesis varied from 23 to more than 200 µm, but most of them were categorized as clinically acceptable. Conclusions AM implant‐supported fixed prostheses demonstrate similar accuracy compared to conventional and computer‐aided design and computer‐aided manufacturing techniques in vitro. Detected inaccuracies of AM restorations do not exceed clinically acceptable limits. Clinical studies with longer follow‐up periods are needed to show the reliability of AM prostheses.
