It is a technique-sensitive procedure, and ensuring the precision and fit of RSMs can be challenging due to the shrinkage of self-curing resin during polymerization [17; 18]. However, with the advent of computer-aided design/computer-aided manufacturing (CAD/CAM) technology, manufacturing more accurate RSMs has become possible. These RSMs can be made from materials such as poly methyl methacrylate (PMMA) or acrylic resin, which are lightweight and provide stable results [16]. In case of any growth-related changes, 3D-printed RSMs offer added flexibility as they can be easily trimmed, adjusted, refined, or even reprinted since digital files are readily available [19]. The band and loop is the most commonly used type of fixed space maintainer (SM), particularly in cases of unilateral tooth loss or bilateral loss of primary molars when the permanent incisors have not fully erupted [12; 13; 20; 21; 22]. In situations where there is early loss of a primary first molar, placing an SM on the primary second molar before the eruption of the permanent first molar is crucial to prevent mesial migration and loss of space [23]. This type of SM consists of two components: the loop, which passively rests on the adjacent tooth and extends over the edentulous space, and the band that encircles the abutment tooth [20; 21; 22]. Lab-based band and loop SMs have certain disadvantages, including solder failure, corrosion, time-consuming construction, inadequate band pinching, and the potential development of caries along the band's margin [24; 25]. Challenges such as transferring the pinched band onto the impression and controlling the flame during the soldering process further complicate the procedure, as overheating can lead to breakage [26]. Additionally, achieving optimal results with lab-based SMs requires close collaboration between the dentist and the dental lab technician [27]. As an alternative to the conventional band and loop SMs and to overcome their disadvantages, some studies have suggested the use of technique-sensitive fiber-reinforced composite resin (FRCR)-based space maintainers, including polyethylene fibers, pre-impregnated silanized E-glass fibers with Bis-GMA, with or without PMMA, and CAD/CAM-aided ceramic-based and polymer-based SMs [16; 21; 25; 28; 29; 30; 31; 32; 33]. Digital impressions have emerged as a technology that enhances patient confidence and cooperation, increases procedural efficiency, and reduces long-term costs. Instead of relying on conventional dental casts, digital impressions allow dental professionals to work with digital 3D models [11; 34]. This technology also enables digital documentation, eliminating the need for physical storage of patient data [35]. Intraoral scanners, which capture digital impressions, offer a safer alternative to conventional impressions by eliminating the risk of aspiration or ingestion [11; 34]. In fact, a study revealed that 77% of patients prefer intraoral scans over traditional impressions [36]. In pediatric dentistry, the use of intraoral scanners has several advantages. It improves children's cooperation by allowing pauses during scanning and offers a real-time visual representation of what is happening in the mouth through familiar photographs, thereby sparking the child's curiosity [11; 34]. When utilizing intraoral scanners in pediatric patients, it is crucial to consider the size of the scanner head. This factor affects intraoral maneuverability and scanning time and should be compatible with the shallow vestibules and limited mouth opening in children and young patients [37]. There are two approaches to consider after generating digital models: printing the models and proceeding with a conventional procedure or utilizing a digital process for the design stage of the space maintainer. Due to various clinical and procedural challenges associated with conventional space maintainers, alternative 3D-printed SMs have been proposed and documented.
