Effects of material and coefficient of friction on taper joint dental implants
ConclusionThe findings indicate differences in the coefficients of friction of cpTi, Ti alloy, and YSZ before, during, and after loading. Fractures caused by stress did not depend on the use of different materials (Ti alloy and YSZ) at the abutment. (Source: Journal of Prosthodontic Research)

A simple 3-point flexural method for measuring fracture toughness of the dental porcelain to zirconia bond and other brittle bimaterial interfaces
ConclusionsEquations were derived to measure interfacial fracture toughness of brittle materials using a novel simple 3-point flexural test method. The test was then validated; estimates for the fracture toughness for the porcelain to zirconia bond, overlapped with previously published data derived from more complex 4-point notched tests.

Periodontal health in shortened dental arches: A 10-year RCT
Conclusions: In view of lacking substantial differences for CAL-V and PPD, the overall differences were considered of minor clinical relevance. The results add confirmatory evidence to the shortened dental arch concept and its clinical viability (controlled-trials.com ISRCTN97265367). (Source: Journal of Prosthodontic Research)

Effect of adding silver nanoparticle on physical and mechanical properties of maxillofacial silicone elastomer material-an in-vitro study
ConclusionThe present study findings suggest that addition of silver nanoparticles at 20 ppm concentration decreased the hardness of Teksil 25(S25) silicone elastomer, and it did not affect tear strength and color stability. (Source: Journal of Prosthodontic Research)
