“…3D design and manufacturing have lessened the time-lasting process of manufacturing prosthetic restorations, removable and fixed orthodontic devices, space maintainers, dental crowns, and surgical guides. [21][22][23][24][25] is design also has the advantage of personal customizing following the needs of individuals. e single-unit manufacturing of the appliance removes the risk of solder breakage and eliminates the laboratory process, lessening the chairside time by simplifying the complex workflows.…”

Objectives: The intraoral use of commercial printable polymers in dental patients is still a challenge due to the unknown physical properties of the materials. The present study aimed to comparably evaluate the maximum load and deflection values of three-dimensional-printed resin blocks in different diameters that can be used intraorally in dental patients. Material and Methods: Forty-five cylindrical resin blocks in diameters of 2 mm (Group 1, n = 15), 3 mm (Group 2, n = 15), and 4 mm (Group 3, n = 15) and lengths of 20 mm were designed and printed. The samples were placed in the universal testing device to conduct the 3-point bending test. According to the Shapiro–Wilk normality test results, Kruskal–Wallis and Mann–Whitney U tests were performed for the statistical analysis. The level of statistical significance was accepted as P < 0.05. Results: The values for the maximum load (N) and deflection (mm) in the study groups were 218.4 ± 31.9, 2.96 ± 0.86 in Group 3; 77.05 ± 61.5, 3.91 ± 0.92 in Group 2; and 19.67 ± 2.63, 4.06 ± 1.02 in Group 1, respectively. The mean values of maximum load for Group 3 were superior to Group 2 (P = 0.020) and Group 1 (P = 0.00). Group 2 revealed higher maximum load results than Group 1 (P = 0.003). The mean values of maximum deflection in Group 3 were lower compared to Group 2 (P = 0.014) and Group 1 (P = 005). Conclusion: The results of this in vitro study encourage the use of resin-printed intraoral appliances in place of conventional treatment modalities.

“…Chemical resistance, high-temperature stability, dimensional stability and a wide range of processing possibilities are all provided by the material. There are some studies of posterior fixed maintainers [33][34][35][36] that showed satisfaction in the young patients. However, there has been no study about aesthetic space maintainers with this procedure.…”

Space maintenance for children at very early ages in primary molars or posterior sectors is widely used and the scientific evidence is clear as to its indications. In the anterior sectors there are doubts as to whether there is a loss of space and its use is usually accompanied by aesthetic, phonatory requirements or the completion of certain habits. In this type of aesthetic anterior maintainer, there are many medium and long-term complications that can occur. Purpose: To evaluate the factors determining possible complications capable of reducing the longevity of aesthetic fixed space maintainers placed due to premature loss of temporary upper anterior teeth. Methods: Data were collected on 100 patients of 1–5 years of age requiring fixed space maintainer placement in the upper anterior area due to caries or traumatisms. Results: Complications were recorded in the form of resin tooth fracture (in 41% of the cases), welding fracture (16%), detachments (28%), gingivitis (26%) and root resorptions (8%). Space maintainer placement in younger children (12–24 months of age) was associated with a significantly greater incidence of root resorptions (p < 0.05). Conclusions: Within the limits of the present study, it is concluded that fixed space maintainers would be a good treatment option in patients with prematurely missing anterior teeth, though the use of temporary first molars as abutments could imply a greater risk of failure, with a lesser incidence of root resorptions. Periodic checks and adequate measures of hygiene are essential.

“…After performing a best-fit alignment, the abutment teeth were selected, and a 3D deviation analysis was conducted. The results indicated no significant differences in the fit of the conventional and 3D-printed metallic band-loop space maintainers (p-value = 0.56) [39].…”

Background: Three-dimensional (3D) printing is an innovative technology widely used in dentistry for manufacturing objects of various shapes using different materials. It has gained increasing popularity in the field of pediatric dentistry, particularly in the production of space maintainers, which serve as a preventive orthodontic treatment following the early loss of primary molars. Aims: In this systematic review, we present a comprehensive overview of the manufacturing process for space maintainers, ranging from traditional procedures to the advancements in 3D printing technology. Materials and Methods: Our review adheres to the PRISMA criteria and includes scientific articles published until 27 May 2023, without any restriction on the publication period and language. To conduct our research, we searched electronic databases, such as Medline, Web of Science, and Embase, using specific keywords and MeSH terms. Results: We identified 9 articles that discussed the CAD/CAM manufacturing and 3D printing of various types of space maintainers. Conclusions: Based on this systematic review, it is evident that 3D-printed space maintainers offer great potential as an alternative to conventionally processed ones, by addressing their limitations. However, further studies are required to evaluate the accuracy, efficacy, and clinical success rates of different 3D printing technologies, materials, and designs for additive manufacturing of space maintainers.
