Soft occlusal splint and hard occlusal splint on the treatment of sleep bruxism or clenching

目的观察硬性垫和软性垫治疗夜磨牙或紧咬牙的临床效果。方法对58例夜磨牙或紧咬牙患者随机采用硬性垫或软性垫进行治疗,28例使用硬性垫,30例使用软性垫。患者每天佩戴垫8 h以上,睡眠时佩戴,佩戴垫后1个月、2个月、3个月、6个月复诊,问诊并记录肌肉酸痛症状,以及夜磨牙或紧咬牙习惯与佩戴前是否有变化。对佩戴垫6个月时的治疗有效率用SPSS 17.0软件行卡方检验。结果治疗6个月时软性垫和硬性垫的治疗有效率分别为93.33%、82.14%,差异无统计学意义(c2=1.709,P=0.191)。结论硬性垫和软性垫的临床治疗效果均较好,软性垫因制作简便、佩戴舒适,更易被患者接受。
