Premature primary tooth loss may result in deleterious changes in dental arch integrity like space loss, crowding and midline shift, compromising the eruption of succedaneous teeth and altering the development of normal occlusion. The most confident way to cope with these problems is through the use of space maintainers. Today is an era of bondontics, which gives us a chance to test challenging materials like glass fiber reinforced composite resin (GFRCR) as a space maintainer. The objective of this study was to assess the clinical efficacy of GFRCR as a space maintainer and to compare it with the conventional Band and Loop space maintainer.
Twenty children aged 4-9 years requiring bilateral space maintainers for premature loss of primary first molar or primary second molar were selected for the study. GFRCR and Band and Loop space maintainers were applied bilaterally and their retention was evaluated at 1, 3 and 5 months interval.
In comparison to band and loop space maintainers, the GFRCR space maintainers showed a higher success but the difference was statistically non significant.
This study showed that GFRCR space maintainer can be a new alternative to the conventional space maintainer for short-term space maintenance for primary tooth loss.
乳牙过早缺失可能会导致牙弓完整性出现有害变化，如间隙丧失、牙列拥挤和中线偏移，影响恒牙的萌出并改变正常咬合的发育。应对这些问题最可靠的方法是使用间隙保持器。如今是粘结正畸学的时代，这使我们有机会测试像玻璃纤维增强复合树脂（GFRCR）这样具有挑战性的材料作为间隙保持器。本研究的目的是评估GFRCR作为间隙保持器的临床疗效，并将其与传统的带环式间隙保持器进行比较。
选取20名年龄在4至9岁之间、因乳磨牙过早缺失而需要双侧间隙保持器的儿童作为研究对象。双侧分别应用GFRCR和带环式间隙保持器，并在1、3和5个月的间隔时间评估其固位情况。
与带环式间隙保持器相比，GFRCR间隙保持器显示出更高的成功率，但差异无统计学意义。
本研究表明，GFRCR间隙保持器可作为传统间隙保持器的一种新的替代方法，用于乳牙缺失后的短期间隙维持。
