Subperiosteal implant is the treatment of choice for the fully or partially edentulous atrophic mandible if grafting procedures are not contemplated to give the jaw sufficient available bone for endosseous implants. The main disadvantage of the standard technique for the construction of this implant is that it requires two surgical procedures. However, it is an accepted and proven technique with a long-term survival rate. This paper discusses the use of the CT scan subperiosteal implant, which provides a result similar to that of the standard subperiosteal implant, but requires only one surgical procedure. The accuracy of fit of the CT scan subperiosteal implant is similar to that of the implant fabricated by means of a standard two-surgical-impression technique. New updated CT scan machines use faster helical scanners and offer a great improvement over previous CT scan machines. The new CT scan machines reduce the chance of patient movement, produce a more accurate CT scan, and enable a more accurate model of the mandible or maxilla to be developed. This paper discusses the production of a well-fitting CT scan subperiosteal implant by a trained, knowledgeable, and cooperative team of dentist, CT scan technician, and radiologist, all of whom understand the technical means to achieve their goal.
如果不考虑进行植骨手术以给下颌提供足够的可用骨来植入骨内种植体，对于全口或部分无牙的萎缩性下颌骨，骨膜下种植体是首选的治疗方法。构建这种种植体的标准技术的主要缺点是需要两次外科手术。然而，它是一种被认可且经过验证的技术，具有较高的长期存留率。本文讨论了CT扫描骨膜下种植体的应用，其效果与标准骨膜下种植体相似，但仅需一次外科手术。CT扫描骨膜下种植体的贴合精度与通过标准的二次手术取模技术制作的种植体相似。新型的CT扫描机采用了更快的螺旋扫描仪，相较于以前的CT扫描机有了很大改进。新型CT扫描机减少了患者移动的几率，能产生更精确的CT扫描图像，并能构建更精确的下颌骨或上颌骨模型。本文讨论了由训练有素、知识渊博且相互协作的牙医、CT扫描技师和放射科医生团队制作贴合良好的CT扫描骨膜下种植体的过程，他们都了解实现目标所需的技术手段。
