Abstract

Objective: To investigate the effect of the time between 3D printing and post-print processing (lag time) on the modulus and radiant energy penetration of 3D-printed indirect bonding jig materials.

Materials and methods: Three 3D-printed resins (Formlabs IBT Resin, SprintRay IDB 2, Pro3dure GR-18.1 IB) were tested for three lag times (0, 16 and 64 h; n = 10 per group). Radiant energy penetration was measured using a power meter, and Vickers hardness was assessed for composites cured through the samples. Mechanical properties were evaluated using uniaxial testing and three-point bending.

Results: Both the resin type and lag time significantly affected radiant energy penetration and composite hardness. The effect of lag time varied by resin. Young's modulus from uniaxial testing showed significant changes only for the Pro3dure resin, while three-point bending indicated significant flexibility changes only for the SprintRay IDB 2 resin.

Conclusions: The resin type and the lag time before post-print processing influence important functional properties of 3D-printed indirect bonding jig materials, including radiant energy penetration and flexibility. These findings suggest that optimising lag time may enhance the performance of 3D-printed indirect bonding jig materials.

期刊介绍： Orthodontics & Craniofacial Research - Genes, Growth and Development is published to serve its readers as an international forum for the presentation and critical discussion of issues pertinent to the advancement of the specialty of orthodontics and the evidence-based knowledge of craniofacial growth and development. This forum is based on scientifically supported information, but also includes minority and conflicting opinions. The objective of the journal is to facilitate effective communication between the research community and practicing clinicians. Original papers of high scientific quality that report the findings of clinical trials, clinical epidemiology, and novel therapeutic or diagnostic approaches are appropriate submissions. Similarly, we welcome papers in genetics, developmental biology, syndromology, surgery, speech and hearing, and other biomedical disciplines related to clinical orthodontics and normal and abnormal craniofacial growth and development. In addition to original and basic research, the journal publishes concise reviews, case reports of substantial value, invited essays, letters, and announcements. The journal is published quarterly. The review of submitted papers will be coordinated by the editor and members of the editorial board. It is policy to review manuscripts within 3 to 4 weeks of receipt and to publish within 3 to 6 months of acceptance.
