“…The linear measurement values of both values are ≤ 0.25mm in the semiwrapped guide. Similar results were reported by Castilla et al [28] and Palone et al [29] . Compared with the Angle measurement values, there were deviations in torque and tip direction between the two methods, with the torque deviation being signi cantly large.…”

This study summarizes the effect of high quality medical carefour-hand operation mode in indirect bonding technology. The technology was applied to the palisade guide for excess binder production and the transfer accuracy of the pallet. Materials and methods: Upper dental arch data of an elderly patient with periodontitis was obtained using an intraoral scanner. Twenty upper dental arch models were 3D printed. 3Shape, PlastyCAD software, and 3D printing technology were used to obtain ten 3D printed palisade guides (3D PPG Method I) and semi-wrapped guides (SWG Method II). The bracket was transferred from the guide plate to the 3D printed upper dental arch model. After the bracket transfer, the excess binder, linearity, and Angle errors were measured through a four-hand operation, including preoperative preparation, intraoperative coordination, and postoperative care. The differences between the two methods were also analyzed. Results: The comparison of the two methods revealed that the SWG of 9.673(8.185-11.237) was greater than 3D PPG (P<0.001) in terms of excess binder – The difference was statistically significant. Further, SWG’s vertical direction error was 0.191 (0.136-0.210) in terms of linear error, which was greater than that of 3D PPG (P<0.001)- The difference was statistically significant. In terms of Angle deviation, the SWG’s Tip and Torque were 0.788 (0.717-0.825) (P<0.05) and 0.908 (0.855-0.983) (P<0.001), respectively. Both of these values were greater than that of 3D PPG and were statistically significant. Thus, all these results favoured 3D PPG. The study data of anterior teeth, cusp teeth, and premolars showed that the premolars were excess adhesive (P<0.05), and both methods had statistical significance. The 3D PPG were premolars Vertical(P<0.05), while the SWG premolars were Transversal and Torque(P<0.05), and the anterior Rotation(P<0.05)- All the values were statistically significant. Conclusions: Skilled medical care four-hand operation was necessary for the palisade guide to achieve less adhesive residue and higher bonding accuracy. Among them, the residual amount of binder, linear, and angular error of the palisade guide was less than that of the semi-wrapped guide, which was conducive to clinical popularization.

“…For instance, a comparative study between traditional drafting methods and modern CAD systems for the design of a large-span sports arena showed a 40% decrease in design time with CAD utilization. Furthermore, error rates in the design phase were reduced by approximately 30%, primarily due to CAD's superior precision and error-checking capabilities [2]. Mathematical models further substantiate these findings, with algorithms designed to calculate error propagation in manual versus CAD designs illustrating a marked decrease in cumulative design inaccuracies when using CAD.…”

The integration of Computer-Aided Design (CAD), Building Information Modeling (BIM), and Internet of Things (IoT) with Artificial Intelligence (AI) represents a transformative shift in the architectural and engineering practices for large-span structures. This paper delves into the quantitative and qualitative enhancements brought about by these technologies, focusing on their pivotal roles in design precision, structural analysis, project management, and maintenance strategies. CAD's evolution from simple drafting to complex 3D modeling has significantly reduced design time and errors, while its integration with structural analysis software has improved load distribution accuracy and material cost efficiency. BIM's contribution to design, construction, and sustainability emphasizes optimized resource allocation and energy-efficient practices. Furthermore, IoT and AI's role in real-time monitoring and predictive maintenance underpins a proactive approach to structural health, ensuring longevity and safety. Through statistical analysis, mathematical modeling, and case studies, this paper highlights the synergistic impact of these technologies on reducing project timelines, enhancing collaboration, and fostering innovation in large-span structure engineering. The findings advocate for a multidisciplinary approach, combining engineering expertise with advanced computational tools to achieve superior outcomes in the construction and maintenance of large-span structures.

“…On the other hand, indirect bonding has some disadvantages. If total time is considered, the clinical and digital programming time is significantly greater than traditional direct bonding, which in turn leads to increased costs ( Brown, 2009 ; Palone, 2023 ).…”
