临床上拍照牙片,胶片通常需患者用手指于口内按压固定,尤其下颌磨牙根尖片,由于胶片接触舌根,加上手指的刺激,容易引起病人恶心,呕吐,常常使胶片固定失败。遇上儿童拍照牙片则困难更大。为此,我们用复合充填树脂自制了一种简便的X线牙片拍照用(牙合)式固定夹(以下简称片夹),经临床使用,效果良好。 Clinic photographs of dental films, the film usually require patients to press the mouth fixed with the mouth, especially the mandibular molars apical films, as the film contact tongue base, coupled with the stimulation of the fingers, easily lead to nausea, vomiting, often making the film failed to fix. Encounter a child photograph tooth is more difficult. To this end, we use a composite filling resin made a simple dental X-ray film (occlusal) type clip (hereinafter referred to as clip), the clinical use, the effect is good.
