UNASSIGNED: A scoping review of scientific evidence was accomplished, involving different databases. MesH terms and keywords were provided to examine clinical trials (CTs) in all languages. Exclusively CTs that fulfilled the eligibility criteria were admitted.
UNASSIGNED: Eight CTs were chosen. These experiments evaluated 542 patients. Four CTs compared the computer-aided indirect bonding method versus the traditional direct bonding of orthodontic brackets. Three CTs compared CAD/CAM retainers with other types of retainers, and one CT compared the CAD/CAM group with multistranded stainless steel wires versus stainless steel wires. Regarding the efficacy of the interventions with CAD/CAM technology used in orthodontics, variable results were found. The indirect bonded customized CAD/CAM brackets presented just a slight effect on the treatment efficacy and therapy results. Two CTs showed that an indirect bonding self-ligating standard system had a similar quality of therapy in comparison with the CAD/CAM customized bracket system. Concerning the clinical failure rate, no differences were presented between the CAD/CAM retainer and other retainers. A CAD/CAM system had more loose brackets than a noncustomized system and was observed also a greater amount of immediate debonding with CAD/CAM indirect bonding than with direct bonding. CAD/CAM fixed retainers revealed inferior relapse and fewer failures than lab-based and conventional chairside retainers. No changes between treatment groups were observed regarding the total therapy time, amount of appointments, and quantity of archwire bends.
UNASSIGNED: In general terms, no greater efficacy of CAD/CAM technology was observed over traditional therapies used in orthodontics. However, it was found that gingival inflammation and the accumulation of bacterial plaque and dental calculus were lower when CAD/CAM retainers were used. When comparing interventions that include CAD/CAM systems with conventional therapies, no significant reduction in care times was found.
■完成了对科学证据的范围审查,涉及不同的数据库。提供了MesH术语和关键字以检查所有语言的临床试验(CT)。仅符合资格标准的CT被录取。
■选择了8个CT。这些实验评估了542名患者。四个CT比较了计算机辅助间接粘结方法与传统的正畸托槽直接粘结方法。三个CT将CAD/CAM保持器与其他类型的保持器进行了比较,一个CT将CAD/CAM组与多股不锈钢丝和不锈钢丝进行了比较。关于在正畸中使用CAD/CAM技术进行干预的有效性,发现了变量结果。间接粘合定制CAD/CAM支架对治疗效果和治疗结果仅有轻微影响。两个CT显示,与CAD/CAM定制支架系统相比,间接结合自结扎标准系统具有相似的治疗质量。关于临床失败率,CAD/CAM固定器和其他固定器之间没有差异.CAD/CAM系统比非定制系统具有更多的松动支架,并且还观察到CAD/CAM间接粘合比直接粘合更多的立即脱粘。CAD/CAM固定固位体比基于实验室的和传统的椅边固位体显示出较差的复发和更少的失败。治疗组之间没有观察到总治疗时间的变化,预约量,弓丝弯曲的数量。
■总的来说,没有观察到CAD/CAM技术比传统正畸治疗更有效。然而,发现当使用CAD/CAM保持器时,牙龈炎症和细菌菌斑和牙结石的积累较低。在将包括CAD/CAM系统的干预措施与常规疗法进行比较时,未发现护理时间显著缩短.
