本研究的目的是评估和比较传统的“四合一”技术与数字微笑设计的计算机辅助“四合一”康复;随访4年。该方案应用于总共50例随机招募的患者，并分为两组。数字协议允许对固定装置的精确位置进行完全虚拟的规划，这允许人们以很高的精度执行无翻瓣手术程序（微创手术），并且还可以使用通过计算机辅助设计/计算机辅助制造（CAD/CAM）实现的虚拟规划的假体（用于立即加载植入物的方法）。治疗4年后，传统方案治疗组的成功率为98%，数字方案治疗组的成功率为100%。在每个时间间隔，检测到两组之间种植体周围牙槽骨丢失的显著差异;传统组4年时的平均边缘骨丢失（MBL）为1.12 ± 0.26 mm，数字组为0.83 ± 0.11 mm。属于数字组的患者认为即时加载（92%），数字微笑预览（93%），模拟测试（98%）和引导手术（94%）非常有效。与使用传统治疗康复的患者相比，所有使用数字方法治疗的患者报告的术中和术后疼痛值较低。总之，在本研究中所描述的全数字协议是一个有效的治疗替代传统的“所有对四”协议的种植体支持的修复无牙弓。
The aim of the present study was to evaluate and compare the traditional “All on Four” technique with digital smile designed computer-aided “All on Four” rehabilitation; with a 4-years follow-up. The protocol was applied to a total of 50 patients randomly recruited and divided in two groups. Digital protocol allows for a completely virtual planning of the exact position of the fixtures, which allows one to perform a flapless surgery procedure with great accuracy (mini-invasive surgery) and also it is possible to use virtually planned prostheses realized with Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) (methods for an immediate loading of the implants. After 4 years from the treatments 98% of success were obtained for the group of patients treated with the traditional protocol and 100% for the digital protocol. At each time interval a significant difference in peri-implant crestal bone loss between the two groups was detected; with an average Marginal Bone Loss (MBL) at 4 years of 1.12 ± 0.26 mm in the traditional group and 0.83 ± 0.11 mm in the digital group. Patients belonging to the digital group have judged the immediate loading (92%), digital smile preview (93%), the mock-up test (98%) and guided surgery (94%) as very effective. All patients treated with a digital method reported lower values of during-surgery and post-surgery pain compared to patients rehabilitated using traditional treatment. In conclusion, the totally digital protocol described in the present study represents a valid therapeutic alternative to the traditional “All on Four” protocol for implant-supported rehabilitations of edentulous dental arches.
