我们选用的材料是卫生部口腔种植科技中心研制的钛金属种植体,有螺旋及叶状的两种,螺旋状种植体长度为18～20mm,直径为2.5～3.0mm,种植器械为5件套,术前均采用高压消毒。 手术方法:手术前拍摄颌骨全景片及牙片,血液常规检查,口腔检查重点为缺牙区的骨组织、牙龈、粘膜、咬合关系及邻牙健康情况,然后取全口模型,在模型上进行设计、测量等准备工作。螺旋状种植体一般不用切开牙龈,用小于种植体的0.1mm的专用钻头在牙槽骨上直接钻孔,然后用丝锥成形,最后将螺旋体旋入拧紧。叶状种植体应首先切开牙龈、粘骨膜,用裂钻开槽,其长度应和种植体长度一致,深度以种植体低于牙槽骨表面下1～2mm左右位置,倾斜度应和牙体长轴方向一致,调正咬合,缝合切口,1周后拆线。 修复方法:在全口模型上作舌腭侧背板蜡型进行包埋铸造,铸件与种植体连接成一个整体。然后进行种植义齿的配色、排牙雕塑、热处理、打磨及粘接等。如果没有铸造设备,可暂时采用光敏固化或自凝塑胶一次成型的方法进行修复。
The materials we choose are titanium implantations developed by the Ministry of Health's Oral Implantation Technology Center. There are two types of helical implants: 18-20 mm in length, 2.5-3.0 mm in diameter, and 5 sets in planters Preoperative use of high pressure disinfection. Surgical methods: Preoperative panoramic photography of jaws and teeth, blood routine examination, the focus of oral examination for edentulous bone tissue, gums, mucosa, occlusal relationship and adjacent teeth health, and then take full-mouth model, in the model Conduct design, measurement and other preparatory work. Spiral implant generally do not have to cut the gums, with a smaller than the implant 0.1mm drill bit directly on the alveolar bone, and then tap forming, and finally the screw body screwed tighten. Leaf-shaped implant should be the first to cut the gums, mucoperiosteal, with a split-notch drilling, the length should be consistent with the length of the implant, the depth of the implant below the surface of the alveolar bone about 1 ~ 2mm, the inclination should be teeth Long axis consistent body alignment is correct occlusion, incision, stitches after 1 week. Repair methods: in the full mouth model for the tongue palatal back wax type embedded casting, casting and implant connection as a whole. And then planting denture color, tooth sculpture, heat treatment, grinding and bonding. If there is no casting equipment, can be temporarily used photosensitive curing or self-curing plastic one-way repair.
