- Abstract
The article describes the increasing digitization in orthodontics and dental technology. Through digital scanning and design systems, orthodontists can create more precise impressions and communicate more efficiently with colleagues and laboratories. Digital model production offers advantages such as faster workflows and higher accuracy of appliances. Various methods of impression taking and the advantages and disadvantages of laboratory scanners and intraoral scanners are discussed. The authors emphasize the importance of powerful software and hardware to ensure a smooth workflow. The article addresses various questions related to intraoral scanning systems. Questions are asked about system compatibility, handling of the handpiece, license and support fees, data storage, and battery life. It also discusses digital model production and the archived management of patient data. A table compares the performance and costs of different intraoral scanning systems. Finally, the physical production of 3D-generated models and the various printing processes are explained. The article describes the use of DLP printers in dental laboratories. These printers use a DLP projector as a light source to expose the build platform faster and more evenly. The Organical® 3D Print X1N enables the 3D printing of patient-specific bonding trays for orthodontic treatments. The printing of up to four transfer trays takes only 40 minutes. However, cleaning and post-curing of the printed models require additional steps and special devices. Hollow models should be provided with ventilation holes to avoid problems during the printing process. The choice of the right printing material and printing parameters is crucial for the quality of the printed models. The article describes the process of 3D printing objects and provides instructions for checking the suitability of resins for printing fine details. It explains how to check the film of the resin tank and how to prepare the build platform. It also explains how to determine the volume of resin to be filled and how to transfer the data from the 3D dataset to the printing system. The article also mentions the use of filament printers as an alternative in the field of orthodontics and explains the operating principle of this method. Some limitations of filament printing are also mentioned, such as warping or delamination in thin structures. The orientation of the parts also plays a role in print quality. The present passage compares the manual production of models with digital production. The temporal and economic advantages and disadvantages of both methods are compared. In the manual production of a plaster model, the impressions of the upper and lower jaw are disinfected, the plaster is mixed by hand and poured into the impressions. After the plaster has hardened, the models are trimmed. In digital production, the model is scanned, the STL file is edited, and the model is placed on a base. The individual steps of digital model production are listed in Table 6. The article describes the possibilities of digitally archiving orthodontic models. Digital archiving allows for analysis and simulation of treatments without damaging the models. Various variants of archiving are mentioned.
