Three-dimensional evaluation of marginal and internal fit of 3D-printed interim restorations fabricated on different finish line designs
ConclusionsThe fabrication methods showed more of an influence on the fit compared to the effect of the finish-line design in both milled and printed restorations. SLA-printed interim restorations exhibit lower marginal and internal gap than milled restorations. Nonetheless, for both techniques, all values were within the reported values for CAD/CAM restorations.Significance3D-printing can offer an alternative fabrication method comparable to those of milled restorations.

Biomechanical behavior of adhesive cement layer and periodontal tissues on the restored teeth with zirconia RBFDPs using three-kinds of framework design: 3D FEA study
ConclusionsThe risk for framework-debonding in three-unit RBFDPs was substantially lower than that in two-unit RBFDPs. In difficult cases with indication for three-unit RBFDPs, two-unit cantilever design using the canine would be more advantageous for preservation of periodontal tissue, while for risk of framework-debonding, the design using the central incisor would be more advantageous.

Ultimate force and stiffness of 2-piece zirconium dioxide implants with screw-retained monolithic lithium-disilicate reconstructions
ConclusionsThe examined 2-piece ZrO2 implant system mounted to LS2-restorations seems to be a stable unit under in-vitro conditions with mechanical properties compared to loading capacity of physiological force. The metal-free implant reconstructions demonstrated high stiffness and ultimate force under quasi-static load for single tooth replacement under consideration of the dental indication of narrow and standard diameter implants.

Properties of tonic episodes of masseter muscle activity during waking hours and sleep in subjects with and without history of orofacial pain
ConclusionsWithin the limitations of this study, it would be concluded that sustained TEs may have a correlation with orofacial pain and the intensity range of 7.5–25% MVC would be an important range for future clenching studies (Source: Journal of Prosthodontic Research)

Sensory trick splint as a multimodal therapy for oromandibular dystonia
ConclusionsThe sensory trick splint is especially helpful for patients with jaw closing dystonia. It is useful, although partially effective, as an alternative therapy in patients for whom other therapies have been unsatisfactory. (Source: Journal of Prosthodontic Research)
