下颌角部是下颌骨骨折的好发部位之一,其治疗难点最多见的是有关骨折线上第三磨牙的处理,本文作者就此问题进行了研究。 93例下颌骨骨折(以下简称角部骨折)患者,通过X线头影测量,颌骨正侧位片进行诊断,其骨折片移位程度按友寄等分类分为Ⅰ度:骨折线不明显或裂缝骨折;Ⅱ度:骨折片轻度移位;Ⅲ度:骨折片明显移位。骨折线上第三磨牙处理见表1,2。 作者研究的93例97处(4例双侧)角部骨折,其骨折线上91.8％均有第三磨牙,比其他作者报道的发生率高。由此推测,第三磨牙特别是阻生第三磨牙存在有
Mandibular angle is one of the major sites of mandibular fracture, the treatment of the most common is the treatment of the third molars on the fracture line, the authors of this issue were studied. Ninety-three patients with mandibular fracture (hereinafter referred to as “corner fracture”) were diagnosed by X-ray cephalometric analysis. The degree of dislocation of the fracture was classified into Ⅰ degree according to the mailing classification, and the fracture line was not obvious Fracture; Ⅱ degree: slight fracture of the fracture; Ⅲ degree: the fracture was significantly displaced. Fracture line third molar treatment shown in Table 1,2. The authors studied 93 cases of 97 (4 bilateral) corner fractures, the 91.8% of the fracture line has a third molars, higher incidence than the other authors reported. From this speculation, the third molars, especially impacted third molars there
