Abstract

BACKGROUND

Occlusal appliances can distribute aggressive loads which are generated by bruxism and can reduce their frequency. The facebow record, when used in the construction of occlusal appliances, helps in minimizing occlusal discrepancies. This study aimed to compare the effect of CAD/CAM stabilization occlusal splint made with and without facebow for management of bruxer patients.

METHOD

24 Patients who were diagnosed as bruxers were randomly assigned into two equal groups and obtained maxillary CAD/CAM occlusal stabilizing splint recorded with centric relation either with or without using a facebow. The patient satisfaction using the visual analog scale (VAS) was recorded at baseline, one month and three months' follow-up periods. The adjustment time of both splints, from the start of splint delivery until becoming well-fitted and occlusally adjusted, was calculated using a stopwatch.

RESULTS

The CAD/CAM occlusal splints with or without the use of facebow improved the patient's satisfaction with no statistically significant difference between both groups at baseline, one month and three months with p values of 0.73, 0.24 and 0.45 respectively. The comparison between the two modalities regarding the adjustment time showed no statistically significant difference between both groups (P = 0.06).

CONCLUSION

According to the results of this study; no difference was detected in patient satisfaction and the time required for adjustment of CAD/CAM occlus.

摘要

背景

咬合矫治器可分散磨牙症产生的过大负荷,并能降低其发生频率。在制作咬合矫治器时使用面弓记录,有助于将咬合差异降至最低。本研究旨在比较使用和不使用面弓制作的CAD/CAM稳定咬合板对磨牙症患者的治疗效果。

方法

将24例被诊断为磨牙症的患者随机分为两组,分别制作上颌CAD/CAM咬合稳定板,一组使用面弓记录正中关系,另一组不使用。在基线、随访1个月和3个月时,使用视觉模拟量表(VAS)记录患者满意度。使用秒表计算两种咬合板从开始交付到完全贴合并进行咬合调整的调整时间。

结果

使用或不使用面弓制作的CAD/CAM咬合板均提高了患者满意度,两组在基线、1个月和3个月时差异均无统计学意义,p值分别为0.73、0.24和0.45。两种制作方式在调整时间方面的比较显示,两组之间差异无统计学意义(P = 0.06)。

结论

根据本研究结果,在患者满意度和CAD/CAM咬合板调整所需时间方面未发现差异。
