The purpose of the study was to determine hardness and fracture toughness dental yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) manufactured by digital light processing (DLP) technology its clinical prospects.The experimental group DLP-manufactured zirconia, control milled zirconia. investigated under a range test loads (0.49 N, 0.98 1.96 4.90 9.81 29.42 49.03 98.07 196.1 N). Meyer's law applied describe indentation size effect (ISE). Meanwhile, PSR model MPSR were utilized...
The bond strength between the zirconia substrates and porcelain materials has been extensively investigated, sandblasting is one of most effective methods for increasing porcelain. However, it also introduces microcracks pollution, which have a negative impact on final mechanical properties restorations. To increase chimaerism zirconia/veneer structures nondestructively, in this study we developed novel surface design called bionic-patterned microstructure (BSM) using stereolithography (SLA)...
This study aimed to comparatively investigate the effects of accelerated aging on physical and biological features zirconia manufactured by digital light processing (DLP) conventional subtractive manufacturing (SM) with similar composition.Both DLP- SM-fabricated samples (7 mm × 7.5 1.5 mm) were grouped according (134 °C, 0.2 MPa, 100% humidity) times, including 0 h, 5 10 h. Phase assemblage surface topography different technologies evaluated before after aging. The human gingival fibroblast...
The minimum amount of tooth preparation that can be fully controlled is crucial in achieving long-term, stable, and effective aesthetic restoration, which also a major difficulty restoration. imple-mented efficiently accurately through digital technology based on the fixed-deep hole guiding technology. Prior actual preparation, first designs virtual contour, layering, occlusion prosthesis computer. Then, carried out by cutting back according to prosthesis. Next, drilling operation plan...
This study aimed to evaluate the application of digital impression and resin model technology in removable partial dentures (RPD) for Kennedy classⅠandⅡdentition defects.
This study was performed to investigate the microstructure and mechanical properties of dental zirconia manufactured by digital light processing (DLP) 3D printing clinical application prospects this material.The experiment group DLP printing, control (MILL) milled zirconia. The density, grain size, phase composition were measured microstructure. Flexural strength using three-point bending tests, while Vickers hardness determined through a tester. Fracture toughness tested single-edge...
Objective: To investigate the influence of digital light processing (DLP) and computer numerical controlmilling (CNC) on mechanical behavior zirconia. Methods: Prepared DLP samples (experimental group, n=52) CNC (control with 12 in each group were randomly selected using random number table to measure density, grain size crystal phase composition. According different methods fracture toughness test, divided into indentation method (IM) single-edge-V-notch-beam (SEVNB), 30 IM 10 SEVNB group....
