作者根据种植体结构与软硬组织结合方式、咀嚼压力的传导方式的特殊性,种植体的形态直径与天然牙的显著不同,采用种植体与种植体、种植体与天然牙联冠修复设计,兼顾龈健康和唇面美观的边缘设计,并应用室温固化塑料完成种植体桩的工作模型,对46例患者共80个种植体制作了60件烤瓷冠桥修复体,通过2～3年的临床追踪观察,结果表明,①采用室温固化塑料完成种植体桩模型对修复体精度无影响,且可大大降低因模型折裂而致修复体失败的发生率;②联冠设计可增强种植体抵抗外力的能力,提高成功率;③唇侧接触而舌侧离开龈缘的边缘设计,既达到了种植体周自洁及清洁的要求,又有利于义齿的美观。 骨内牙种植体是目前种植义齿修复中最常采用的种植体,由于其形态直径、与牙槽骨组织的结合方式、龈附着及咀嚼压力的传导均与天然牙有显著不同,因此,骨内牙种植体义齿修复亦有其特殊性。作者采用烤瓷熔附金属冠桥修复技术,对46例共80个种植体设计制作了烤瓷冠桥修复体,并通过2
According to the combination of implant structure and soft and hard tissue, the particularity of the conduction mode of chewing pressure, the significant difference between the shape and diameter of the implant and that of the natural tooth, the author uses the implant and implant, implant and natural tooth crown to repair the design, Both gingival health and beautiful lip edge design, and the use of room temperature curing plastic implant model to complete the implant, a total of 46 patients with a total of 80 implants made 60 porcelain crown bridge restoration, through 2 to 3 years The results of clinical observation showed that ① the model of implants implanted with room temperature curing plastic had no effect on the accuracy of the prosthesis and the incidence of prosthetic failure due to the fracture of the model was greatly reduced; ② The crown design enhanced the resistance of implants The ability of external force to improve the success rate; ③ lip side of the tongue and gingival margin edge of the edge of the design, both to achieve the implant self-cleaning and cleaning requirements, but also conducive to the appearance of the denture. Bone implants are the most commonly used implants in prosthesis restoration. Because of their morphological diameter, the combination with alveolar bone tissue, gingival attachment and chewing pressure are all significantly different from that of natural teeth. Therefore, bone Internal denture implant prosthesis also has its particularity. The authors used porcelain fused to metal crown restoration technology, designed 46 porcelain crowns with a total of 80 implants porcelain crown bridge restoration, and through 2
