In the last few years, the mixture of nuclear medicine and the reverse engineering method has confirmed to be an identical key development in the medical field. In contrast, the traditional method has some downsides. For instance, some difficulty presence in matching the well suitable due to the change of patient’s oral state and it takes more attention to meet reliability and comfort. So, the patient-specific prosthesis is required. An additional crucial problem of the patient-specific dental prosthesis is a fabrication method. The prosthesis in dental application is hard to fabricate owing to the multifaceted structures and base material. By the way of ever-growing demands for accuracy, complexity and skin-tight tolerance, traditional methods have turn into unsuccessful for machining them. This paper introduces a methodology for the computer-aided design and additive layer manufacturing of the patient-specific dental implant body for the rehabilitation of teeth. A 3Dimensional model of the dental imperfection is created while the acquirement of helical computed tomography scanning data. Then simulation is made over through software Carestream Dental. Finally, the implant is fixed into the patient’s tooth and the healing phase goes up to 3–6 months depending upon the patient. Then the crown is being fitted. During the healing phase to check the implant’s primary stability, implant stability quotient is checked. The values must be greater than or equal to 50 to attain primary stability. The medical practice exhibited that digital manufacturing and back-engineering software are outstanding mixtures of traits for dental devices designed to withstand tremendous masticatory forces and offer much more flexibility with the customized implant.

在过去的几年中，核医学与逆向工程方法的混合物已被证实是医学领域中一个相同的关键发展。相反，传统方法有一些缺点。例如，由于患者的口腔状态的改变，在匹配合适的井时存在一些困难，并且需要更多的注意力来满足可靠性和舒适性。因此，需要特定于患者的假体。患者专用假牙的另一个关键问题是制造方法。由于多面结构和基础材料，很难在牙科应用中制造假体。通过对精度，复杂性和皮肤耐受性的日益增长的需求，传统方法已无法对其进行机加工。本文介绍了一种用于特定牙齿种植体的计算机辅助设计和添加层制造的方法，以修复牙齿。在获取螺旋计算机断层扫描扫描数据的同时，创建了牙齿缺陷的三维模型。然后通过软件Carestream Dental进行仿真。最后，将植入物固定在患者的牙齿上，并且根据患者的不同，愈合阶段可能长达3–6个月。然后安装表冠。在愈合阶段检查植入物的主要稳定性时，将检查植入物的稳定性商。该值必须大于或等于50才能达到基本稳定性。
