Abstract
INTRODUCTION: Primary teeth serve as the best space maintainer for permanent dentition. 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.
