Abstract:
This systematic review was aimed at gathering technical and clinical applications of CAD/CAM technology for the preoperative planning of craniofacial implants placement, designing of molds and substructures and fabrication of orbital prostheses. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, an electronic search was executed. Human studies that utilized digital planning systems for the prosthetic rehabilitation of orbital defects were included. A total of 16 studies of 30 clinical cases, which were virtually planned through various digital planning and designing software, were included. The most common preoperative data required for digital planning were CT scans in 15 cases, the 3DSS-STD-II scanning system in 5 cases, an Artec Color 3D scanner in 3 cases and a NextEngine Desktop 3D laser scanner in 2 cases. Meanwhile, the digital designing software were Ease Orbital Implant Planning EOIPlan software in eight cases, Geomagic software in eight cases, Simplant software in four cases and Artec Studio 12 Professional in three cases. Surgical templates were fabricated for 12 cases to place 41 craniofacial implants in the orbital defect area. An image-guided surgical navigation system was utilized for the placement of five orbital implants in two cases. Digital designing and printing systems were reported for the preoperative planning of craniofacial implants placement, designing of molds and substructures and fabrication of orbital prostheses. The studies concluded that the digital planning, designing and fabrication of orbital prostheses reduce the clinical and laboratory times, reduces patient visits and provide a satisfactory outcome; however, technical skills and equipment costs are posing limitations on the use of these digital systems.
摘要:
本系统综述旨在收集CAD/CAM技术在颅面植入物放置术前计划中的技术和临床应用。模具和子结构的设计以及轨道假体的制造。遵循系统审查和荟萃分析(PRISMA)指南的首选报告项目,进行了电子搜索。包括利用数字规划系统进行眼眶缺损修复的人体研究。共16项研究,共30例临床病例,实际上是通过各种数字规划和设计软件进行规划的,包括在内。数字计划所需的最常见的术前数据是15例CT扫描,3DSS-STD-II扫描系统5例,ArtecColor3D扫描仪3例,NextEngineDesktop3D激光扫描仪2例。同时,数字设计软件是Ease轨道植入计划EOIPlan软件,在八个案例中,Geomagic软件在八个案例中,植入软件有4例,ArtecStudio12Professional有3例。为12例患者制作手术模板,在眼眶缺损区放置41个颅面植入物。在两种情况下,使用图像引导的手术导航系统放置了五个眼眶植入物。据报道,数字设计和打印系统用于颅面植入物放置的术前计划,模具和子结构的设计以及轨道假体的制造。研究得出的结论是,数字规划,眼眶假体的设计和制造减少了临床和实验室时间,减少患者就诊次数并提供令人满意的结果;然而,技术技能和设备成本对这些数字系统的使用构成了限制。
