隔湿是临床牙科治疗技术不可缺少的步骤,基层口腔医疗机构大多无橡皮障隔湿设备,且操作程序较复杂。单用吸水棉卷隔湿常因舌体及颊部运动而易于滑出,尤其是小儿,配合较差,唾液分泌又多,隔湿有一定困难。我科因陋就简,用“牙用不锈钢丝”弯制隔湿夹,对隔湿起到一定作用,同时也限制了患者不自觉的闭口动作。经临床使用,效果满意。此夹制作简单,操作方便,非常适合基层医疗单位。制作方法:取一段1.2mm不锈钢丝约20cm长,在中间位置用技工梯形钳环绕两周半形成弹簧部分。在两端距弹簧部位约2.5cm处相互交叉至对侧,同时各向两侧方弯制出“U”形翼部分。末端各焊接一与牙体颊舌侧弧度相一致的半环卡,作为固位部分。制作即完 Moisture is an indispensable step in the clinical dental treatment technology. Most of the primary dental care institutions do not have rubber dampers and the operating procedures are complicated. Single absorbent cotton roll Moist often due to the tongue and cheek movement and easy to slide out, especially in children, with poor, saliva secretion and more, separated from the wet has some difficulties. My Section simply because of simple, with “stainless steel wire teeth,” bending the wet folder separated from the wet play a role, but also limit the patient's unconsciously closed mouth. After clinical use, the effect is satisfactory. This clip making simple, easy to operate, ideal for primary health care units. Production Methods: Take a section of 1.2mm stainless steel wire about 20cm long, in the middle position with a mechanic trapezoidal clamp around two weeks and a half to form a spring part. At both ends of the spring from about 2.5cm cross-section to the opposite side, while the sides of the bend on both sides of the “U” -shaped wing. At the end of each welding a semi-circular card consistent with the curvature of the buccal and lingual teeth, as a retention part. Production is finished
