However, in cases with premature loss of primary teeth, the best way to prevent future malocclusion would be to place an effective space maintainer. Aim: This study aimed to evaluate the clinical performance of intraorally scanned and direct metal laser sintered (DMLS) band and loop space maintainers in terms of survival rate, gingival health, and patient satisfaction. Materials and Methodology: In this pilot study, 10 children aged between 4 and 9 years who met the inclusion criteria were selected. Intraoral scanning was performed, and a 3D cast was printed, on which a band and loop space maintainer was fabricated. The printed band and loop were cemented and evaluated at 1, 3, and 6 months. Patient satisfaction was assessed at baseline. Data were subjected to statistical analysis using the Friedman test. Result: The survival rate showed a statistically significant improvement over time, with mean scores increasing from 1.20 at baseline to 2.0 at 6 months (P = 0.001) . Gingival inflammation progressively increased from a score of 1.0‑2.0 over time, showing a statistically significant difference (P = 0.049) . Patient satisfaction at baseline was generally high. Conclusion: The findings highlight 3D printing as a promising advancement in pediatric dentistry, combining superior performance with enhanced patient satisfaction.  \nKeywords: 3D printing, band and loop, digital dentistry, preventive orthodontics  \nIntroduction  \nrimary teeth act as the most efficient natural space  \nmeaviner,tainerwhenuntdheersenormteethal aphreysliolostogpircealmacondturelity,ionthse. best approach to prevent future malocclusion is the use of a reliable, cost-effective, and durable space maintainer.[1] Maintaining the primary dentition until its natural exfoliation is crucial not only for aesthetics, mastication, and speech but also for ensuring the proper eruption and guidance of permanent teeth.[2] As stated by the American Academy of Pediatric Dentistry (AAPD), space maintenance is the preservation of present dentition placement to avoid loss of arch length, width, and perimeter.[3] The use of 3D printing technology to manufacture space maintainers offers precise customization, improving comfort and functionality, and is anticipated to enhance patient compliance.
