目前国内多数口腔科拍摄牙片时,均需患者自己用手指伸入口腔内抵住牙片使之固定,该法存在以下缺点:①患者手指上的细菌、脏物易被带入口腔;②由于手指较粗大,放在口腔后部时,部分患者会感到恶心;③某些患者(如儿童、精神病患者、瘫痪病人等)自己无法固定牙片,需他人帮助,他人的手指易被患者咬伤,也易将细菌、脏物带入患者口腔.为此,设计了一种牙片挟持器,专利号:ZL962432938,现将制作及使用方法介绍如下:本牙片挟持器(见图1,2)包括手柄1、夹板2和夹舌3三部分,均用对人体无毒的塑料制成,一般为一次性使用.手柄与夹板相连,夹舌位于夹板上方,其一端与夹板相连.为了便于使用,手柄与夹板相连接的一端设计成翘起一定角度,为5°～15°.夹板为框形,
At present, most of the dental departments in China take pictures of dentures with their fingers in the entrance cavity to hold them fixed. This method has the following disadvantages: 1 The bacteria and dirt on the patient’s fingers are easily brought into the mouth; 2 Because the fingers are relatively thick and placed on the back of the mouth, some patients may feel nauseous; 3 Some patients (such as children, mental patients, paralyzed patients, etc.) cannot fix the teeth themselves and need help from others. The fingers of others are easily bitten by the patient. Injurious, it is easy to bring bacteria and dirt into the patient’s mouth. To this end, a dental chip holder is designed, patent number: ZL962432938, and the method of production and use is described as follows: The dental chip holder (see Figure 1). 2) The three parts including the handle 1, the splint 2 and the clamping tongue 3 are all made of plastics which are non-toxic to the human body and are generally used for single use. The handle is connected with the splint, and the clamping tongue is located above the splint, one end of which is connected with the splint. Easy to use, the end of the handle and the splint is designed to be tilted at an angle of 5° to 15°. The splint is frame-shaped.
