Influence of different implant operative procedures on morphologic changes in peri-implant alveolar bone and soft tissue: a one-year prospective clinical study
ConclusionsRegardless of the bone and soft tissue augmentation approach, implants with conical connections may effectively preserve peri-implant tissues. However, the thickness of the peri-implant soft tissue is essential, because a change in soft tissue margin level tends to be affected by the thickness of the peri-implant soft tissue rather than the bone width.

Perceptibility and acceptability thresholds of simulated facial skin color differences
ConclusionsChanges in L* were more perceptible and less acceptable than changes in a* and b*. For this reason ΔL* parameter needs attention equally to ΔE*ab when fabricating a facial prosthesis. (Source: Journal of Prosthodontic Research)

Rehabilitation of ectodermal dysplasia patients presenting with hypodontia: outcomes of implant rehabilitation part 1
ConclusionsPatients with ED treated with dental implants reported encouraging outcomes post treatment after prostheses were fitted. Follow-up from 1.6 to 6.8 years has confirmed these improvements. (Source: Journal of Prosthodontic Research)

Highly producible method for determination of occlusal vertical dimension: relationship between measurement of lip contact position with the closed mouth and area of upper prolabium
ConclusionsThese results clarified that the lip contact position with the closed mouth obtained the excellent reproducibility comparing to the conventional methods. These findings suggested that the area of the prolabium of the upper lip might offer an effective index for individual determination of the correct free-way space.

Does the retention system influence the stability of implant-supported maxillary overdentures? A comparison with fixed and conventional dentures
ConclusionsOverdentures retained by a combination of a clip bar and attachment presented better stability and retention capacity under our experimental conditions, close to that of the positive control (fixed complete denture), with the advantages of removable overdentures.

Masticatory function of conventional complete denture wearers changing to 2-implant retained mandibular overdentures: clinical factor influences after 1 year of function
ConclusionsCCD users with poor retention achieved an inferior ST_X50. The STB performance can be compromised by poor stability or Class II characteristics, while brachyfacial individuals achieve better homogenezation of the food bolus. Although the transition to IMO improved the masticatory function, the anteroposterior discrepancy still maintained an association with STB, as Class II individuals still presented difficulties homogenizing food.

Comparing the accuracy (trueness and precision) of models of fixed dental prostheses fabricated by digital and conventional workflows
ConclusionsDigital models had smaller root mean square values of trueness of the complete arch and preparations than stone models. However, the accuracy of the complete arch and trueness of the preparations of 3D printed models were inferior to those of the other groups. (Source: Journal of Prosthodontic Research)

Strength comparison of anterior teeth restored with ceramic endocrowns vs custom-made post and cores
ConclusionsLeucite ceramic endocrowns in incisors may fracture during physiological loading. Endocrowns made of lithium disilicate ceramic are resistant to failure. Posts and prosthetic crowns are still recommended for anterior teeth restorations. (Source: Journal of Prosthodontic Research)

Adhesion procedure for CAD/CAM resin crown bonding: Reduction of bond strengths due to artificial saliva contamination
ConclusionThe long-term durability of bonds between CAD/CAM resin blocks and luting agent cement was significantly reduced by artificial saliva contamination. However, sandblasting or phosphoric acid cleaning can recover bonding effectiveness by 75–85%. (Source: Journal of Prosthodontic Research)

Influence of thermo-mechanical cycling on porcelain bonding to cobalt–chromium and titanium dental alloys fabricated by casting, milling, and selective laser melting
ConclusionsTi-based alloys are more susceptible than Co–Cr to reduction of porcelain bond strength following thermo-mechanical cycling. The porcelain bond strength to Ti-based alloys is affected by the applied metal processing technology. (Source: Journal of Prosthodontic Research)

Measuring system for an attitude angle of a denture using an Inertial Measurement Unit
ConclusionsThe measurement accuracy of this system was equivalent to that of 3-D motion capture system by four infrared TV cameras. The measuring system using the IMU is reliable and easy to analyze the attitude angle of the denture during function. It may serve a diagnostic appliance to evaluate the quality of the denture.

Displacement comparison of CAD–CAM titanium and zirconia abutments to implants with different conical connections
ConclusionAbutments displaced more in the implant that required higher torque values to tighten the abutment. The amount of displacement in both systems was clinically small. Abutment material did not affect the magnitude of displacement. (Source: Journal of Prosthodontic Research)
