材料和形态 本组为1977年以来临床应用钛合金人造髁突治疗患者,男6女1,年龄12～32岁。患病时间8～15年。 所用植入体为国产钛合金(T_(c4)),直径2厘米的棒材,经机械加工成形。 人造髁状突形态(见图1)分为髁状突、颈部、连接杆三部分。髁状突和颈部的形态与正常人解剖形状相似,但体积略小,连接杆与与下颌升枝相连接的部分,其厚度为1.5毫米,宽度为1.2厘米,其长度大小不一,可选择使用。连接杆中央为萎形孔眼,
Materials and morphology This group is the clinical application of titanium artificial condyles since 1977, 6 male and 1 female, aged 12 to 32 years. Ill time 8 to 15 years. Implants used for domestic titanium alloy (T_ (c4)), a diameter of 2 cm bar, formed by mechanical processing. Artificial condyle morphology (see Figure 1) is divided into condyle, neck, connecting rod three parts. The shape of the condyle and neck is similar to that of normal human anatomy but slightly smaller in size. The connecting rod and the part connected to the mandibular ramus have a thickness of 1.5 mm and a width of 1.2 cm and vary in length. Choose to use. The center of the connecting rod is wilting hole,
