“…A recent interesting research focus is the position of the object on the building plate in the stereolithographic printer. Authors have recommended an optimal printing direction to achieve maximal dimensional accuracy (189,190,199). The selection of a build direction will affect the slicing of the object used by the printer in the printing process resulting in a "z-stepping" effect on the surface of the surgical guide.…”

“…44 Variables like layer thickness and build orientation of the object must be decided. Dimensional accuracy of AM devices has been found to be negatively affected by aspects of the manufacturing process, such as build orientation, [45][46][47][48][49][50] number of objects being printed, 51 and the post-processing method. 50,52,53 Once the design and printing parameters have been finalized, the device (or surgical implant guide) will then be printed by the printer selected.…”

Static computer assisted implant surgery (s-CAIS) is an integral part of the digital workflow in implant dentistry and provides the link between the virtual planning environment and surgical field. The accuracy of s-CAIS is influenced by many cumulative factors including the fit of the template which is related to the manufacturing process. This critical review provides an overview of the current research on additively manufactured surgical implant guides.

“…As a result, the 3D-printed CAs were designed at a build angle of 30° and printed using a DLP 3D printer with a 50 µm resolution, based on previous studies. 36,37 Third, a 50 µm offset was applied to the inner surface of the 3D-printed CAs to compensate for the thickness change and to enhance the adaptability. 36 A previous study examining the t of a printed splint showed that splints with 0.05, 0.1, and 0.2 mm offsets can t the teeth better than those without offset.…”

The present study aimed to compare the thickness, gap width, and translucency of 3D-printed and thermoformed clear aligners using micro-computed tomography (micro-CT). Four groups of clear aligners were tested: thermoformed with single-layer material (TS, polyethylene terephthalate glycol) or a multi-layer material (TM, copolyester-elastomer combination), and 3D-printed TC-85 cleaned with alcohol (PA) or with centrifuge (PC). Aligners (n=10) were fitted onto respective models and micro-CT was performed. Thickness and gap width were measured for different tooth type in sagittal sections on all sides. CIELab coordinates were measured (n=5) to compare the translucency. Depending on tooth type and location, thermoformed and 3D-printed clear aligners have significantly varied thicknesses and showed a clinically acceptable range of fit with differences in regions of best fit. Centrifugation in post-processing significantly improved the translucency of 3D-printed aligners.
