Change in the retentive force of Akers clasp for zirconia crown by repetitive insertion and removal test
ConclusionsWhen repetitive insertion/removal of the clasp was performed on MZC, retentive force decreased depending on clasp materials. However, the amount of decrease in retentive force was comparable or small compared to conventional FMC. As a result, it was suggested that MZC could be used on abutment tooth for RPD.

Complete rehabilitation of patients with bruxism by veneered and non-veneered zirconia restorations with an increased vertical dimension of occlusion: an observational case-series study
ConclusionsWithin the limitations of this study, we conclude that the survival and success rate of monolithic zirconia restorations installed in patients with bruxism was excellent, although the veneered zirconia restorations showed a high rate of minor veneer chipping, which required only polishing.

Influence of different preparation forms on the loading-bearing capacity of zirconia cantilever FDPs. A laboratory study
ConclusionsDouble-retainer IRCFDPs showed promising results for replacing single premolars. The inlay design seems to have no significant influence on the fracture strength of these restorations. (Source: Journal of Prosthodontic Research)

Fifteen-year survival of resin-bonded vs full-coverage fixed dental prostheses
ConclusionsThe present study is the first to indicate RBFDP as a prosthetic treatment option which should be selected for patients with slight or no abutment tooth decay. (Source: Journal of Prosthodontic Research)

The influence of prosthetic material on implant and prosthetic survival of implant-supported fixed complete dentures: a systematic review and meta-analysis
ConclusionsProsthetic material selection seems to have no clinically relevant influence on implant- and prosthetic survival rate in implant-supported fixed complete dentures. Due to the high chipping rate, quantifying prosthetic survival alone does not seem to be a reliable tool for evaluating the outcome of the restorations and providing recommendations. These results, along with the obvious lack of evidence, suggest that clinicians must exercise caution whenever porcelain-fused-to-zirconia or metal-resin restorations are considered.

Chewing simulation of zirconia implant supported restorations
ConclusionsBased on the obtained in-vitro results, all tested materials can be recommended for the use on zirconia implants, although CT is only approved for temporary crowns. The loading and retention capacity of the materials were not significantly affected by aging. (Source: Journal of Prosthodontic Research)

Vibratory stimulus to the masseter muscle impairs the oral fine motor control during biting tasks
ConclusionsVibratory stimulus to the masseter muscles impairs the oral force control during a standardized biting task and provide further insight into the sensorimotor regulation of the masticatory system. (Source: Journal of Prosthodontic Research)

Modal analysis of two different types of fixed implant-supported prostheses embedded in edentulous maxillae
ConclusionsThe current study demonstrated less adverse vibration in the 6-abutment prostheses than in the 4-abutment prostheses, suggesting that modal analysis can contribute to novel future developments in the designs of dental implant prostheses. (Source: Journal of Prosthodontic Research)

Simplifying the digital workflow of facial prostheses manufacturing using a three-dimensional (3D) database: setup, development, and aspects of virtual data validation for reproduction
ConclusionsThe utilization of DDB may simplify the digital workflow of facial prostheses manufacturing. The transfer of digitally applied skin wrinkles till the prostheses’ prototypes may be associated with deviations from 11 to 40%. (Source: Journal of Prosthodontic Research)

Bonding of different self-adhesive resins to high-strength composite resin block treated with surface conditioning
ConclusionsThe bond strength of HSCRB was influenced by the chemical conditioning, SARs, and aging. γ-MPTS and 10-MDP application yielded higher μTBS values of mechanically treated HSCRB than the UA. (Source: Journal of Prosthodontic Research)

Substrate masking ability of bilayer and monolithic ceramics used for complete crowns and the effect of association with an opaque resin-based luting agent
ConclusionsCeramic type and the white-opaque resin-based luting agent presented a significant effect on the substrate masking ability. All the discolored substrates tested are adequately masked with veneered zirconia or with LDPc (preferably associated to OLA). The CAD-on technique associated with OLA improved the masking ability over metallic substrates. (Source: Journal of Prosthodontic Research)
