A possible risk of CAD/CAM-produced composite resin premolar crowns on a removable partial denture abutment tooth: a 3-year retrospective cohort study
ConclusionsThe demonstrated complication rate for CAD/CAM composite crowns placed on premolars was 15.9% over a period of up to 3 years. There was a substantial risk of complications with placement of such a crown on an RPD abutment tooth. (Source: Journal of Prosthodontic Research)

A thick frame decreases the fracture toughness of veneering ceramics used for zirconia-based all-ceramic restorations
ConclusionsModification of the firing conditions from the manufacturer’s instructions and inclusion of a thick Y-TZP frame decreased the fracture toughness of veneering ceramics at the interface, suggesting that a thick frame would pose a potent fracture risk in veneering ceramics used for zirconia-based all-ceramic restorations.

Efficacy of mandibular manipulation technique for temporomandibular disorders patients with mouth opening limitation: a randomized controlled trial for comparison with improved multimodal therapy
ConclusionsThe efficacy of manipulation seems to be limited, in contrast to our expectations, and improved execution of therapeutic exercises has a similar effect to that of manipulation during long-term observation. The advantage of manipulation was observed only during the first treatment session. The RCT was registered in the University Hospital Medical Information Network in Japan (UMIN-CTR: 000010437).

Influence of chewing on expression level of human beta-defensin 2 and secretory immunoglobulin A in the epithelium
ConclusionsChewing gum for 30 min increased hBD-2 and SIgA expression levels in skin. Moreover, chewing gum could influence the secretion pattern of these two biomolecules on skin, but not in saliva. (Source: Journal of Prosthodontic Research)

Performance and perception of dental students using three intraoral CAD/CAM scanners for full-arch scanning
ConclusionsIntraoral scanning performance of novice users varied significantly and was dependent on the scanning system used. The questionnaire showed that the overall IOS experience was positive amongst FDS. The perception of time-saving, when using IOS versus conventional impression methods, determined the likelihood of future adoption of the technology. (Source: Journal of Prosthodontic Research)

In vitro 3D and gravimetric analysis of removed tooth structure for complete and partial preparations
ConclusionsZirKnE, LDLCha, and table-top preparations produced the least amount of tooth tissue removal. Three-dimensional volumetric analysis can be a possible alternative to gravimetric analysis. (Source: Journal of Prosthodontic Research)

The potential of three-dimensional printing technologies to unlock the development of new ‘bio-inspired’ dental materials: an overview and research roadmap
ConclusionsConsidering the limitations to both conventional and subtractive computer-aided design/computer-aided manufacturing (CAD/CAM) methods, further research should focus on new, additive 3D-printing techniques. This may open new research paths in dentistry that will enhance the clinical performance of artificial dental materials. (Source: Journal of Prosthodontic Research)

Complete assessment of occlusal dynamics and establishment of a digital workflow by using target tracking with a three-dimensional facial scanner
ConclusionsTarget tracking data were transformed into video clips of dental cast scan data, which showed jaw movements in real time. Occlusal contact information was produced by the CAD software. Both dynamic and static occlusion analyses were performed with reconstructed eccentric movement antagonist meshes. Our new method for reconstructing eccentric movements of the mandible can reveal the occlusal dynamics of a patient within a virtual environment. (Source: Journal of Prosthodontic Research)
