Patients often suffer from sensitivity and pain while preparing the seats of occlusal rests of clasps on abutment teeth with hypersensitive dentine for removable partial dentures prosthesis. Base Nd-YAG laser desensitization effect by making a hard surface layer in the hypersensitive dentine of the abutment teeth, We use this method to treat the teeth before and after occlusal seats of clasps preparation, 20 patients, more than 30 occlusal seats of clasp rests are completed smoothly without any suffering since 1991. All the patients wear their dentures satisfactorily without afterward side effect. After half one year to four years followed observation all the rests adapt to their seats well without marking wear, We believe that the desensitizing effect of Nd-YAG Laser is effective in preparing occlusal seats for removable partial denture prosthesis.
在为可摘局部义齿修复制备基牙上卡环支托的支托窝时，对于牙本质过敏的基牙，患者常感到敏感和疼痛。通过在基牙的过敏牙本质上形成硬表面层，Nd-YAG激光脱敏效果显著。自1991年以来，我们使用这种方法在制备卡环支托窝前后对牙齿进行治疗，20例患者顺利完成了30多个卡环支托窝的制备，过程中无任何痛苦。所有患者佩戴义齿情况良好，无后续副作用。经过半年至四年的随访观察，所有支托与支托窝适配良好，无明显磨损。我们认为Nd-YAG激光脱敏在为可摘局部义齿制备支托窝方面效果显著。
