The aim of this study was to evaluate the clinical performance of simple fixed space maintainers bonded by using a flow composite resin (Tetric Flow) to prevent space resulting from early extracted primary teeth. For that reason, 64 fixed space maintainers (34 in the lower jaw and 30 in the upper jaw) were applied to 45 patients. The patients followed up for 12 to 18 months. Survival rate, prevention ability of that space, and whether damage to the abutment teeth occurred were evaluated. Five percent of space maintainers were determined to be unsuccessful at the end of the control period. During this period, loss of space among the abutment teeth was found to be statistically insignificant (P > .05). Finally, it was observed that the use of simple fixed space maintainers was successful due to operator experience and the choosing of favorable patient groups.
本研究的目的是评估使用流动复合树脂(Tetric Flow)粘结的简单固定间隙保持器预防乳牙早失导致间隙的临床性能。因此,为45例患者应用了64个固定间隙保持器(下颌34个,上颌30个)。对患者进行了12至18个月的随访。评估了生存率、间隙预防能力以及基牙是否受损。在对照期结束时,确定5%的间隙保持器不成功。在此期间,发现基牙间间隙的丧失在统计学上无显著意义(P>.05)。最后,观察到由于操作者的经验和选择有利的患者群体,使用简单固定间隙保持器是成功的。
