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...
Dental implants with long-term success of osseointegration have always been the goal, however, difficulties exist. The accumulation fretting damage at implant-bone interface often gets overlooked. Commonly used titanium is approximately 7-fold harder and stiffer than cortical bone. Stress shielding caused by mismatching elastic modulus aggravates interface, which accompanied risk formation proinflammatory metal debris implant loosening. Thus, authors explore functionalized bone-inspired...
At present, the commonly used clinical protocols of oral comestic restoration are mostly based on aesthetic indicators proposed by Western developed countries (referred to as aesthetics). Mechanically copying scheme, ignoring difference between it and Chinese aesthetics), is unable effectively support personalized cosmetic diagnosis treatment. In addition, new technologies solutions for restoration, which developing rapidly in recent years, emerging one after another, but many popular...
Objective . To evaluate the influence of screw‐tightening methods on immediate and long‐term stability dental implant screw joints. Methodology A total 150 implants three different systems with diameters were used in this study. Each group was divided into subgroups ( n = 5), according to tightening (A—tightening recommended torque retorque after 10 min; B—tightening torque, then loosening retorque; C—tightening only once). The operating time assemblies recorded. Ten minutes later, removal...
Abstract Objective This article describes a novel 3D‐printed template armed with interproximal matrices to isolate contact areas and guide injectable resin composite for consecutive closure of multiple diastema. Clinical Considerations Among several treatment options proposed diastema closure, direct is noninvasive easy repair. The “composite injection technique” has been introduced improve time efficiency reduce technique sensitivity clinicians. However, in the case diastema, overflow...
Abstract Glass-fibre-reinforced polyetherketoneketone (PEKK-GF) shows great potential for application as a dental implant restoration material; however, its surface bioinertness and poor antibacterial properties limit integration with peri-implant soft tissue, which is critical in the long-term success of restoration. Herein, functional magnesium (Mg) silver (Ag) ions were introduced into PEKK-GF by plasma immersion ion implantation (PIII). Surface characterization confirmed that morphology...
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)...
At present, the commonly used clinical protocols of oral cosmetic restoration are mostly based on aesthetic indexes proposed by Western developed countries (referred to as aesthetics), which different from unique Chinese people aesthetics). In design schemes and evaluation effects, these differences have a large or small effect doctor-patient-technology triad. Improper handling could directly weaken cooperation efficiency three parties, reduce patient satisfaction, even lead medical disputes...
For patients with high aesthetic expectation, using removable partial dentures (RPDs) to restore the missing teeth in area rapidly and obtain patients' approval is challenging. This case described an alternative digital protocol solve this situation. A detachable 3DP diagnostic denture was involved procedure, which not only allowed patient evaluate possible outcome of RPD, but also can be duplicated form a definitive by bonding milled PEEK framework customized PMMA dentition containing...
Children with ectodermal dysplasia and complete anodontia experience difficulties in oral rehabilitation because of the small arch size. A case a 7-year-old boy, whose size (length width) was 30-40% smaller than that male adult who presented jaw relation recording using commercially available devices is described. digital workflow involving mini tracer introduced. Primary impressions were made three-dimensionally (3D) printed trays produced based on patient's computed tomography images,...
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....
Abutment is an important component serving as a connecting link between the implant and implant-supported prosthesis. In accordance with mechanical, biological, other conventional norms, it can compensate deviation prosthesis, which plays significant role in maintaining health of peri-implant tissue longevity, stability, effectivity However, choosing anterior abutment correctly conveniently challenging, given great variety clinical practice. Through virtual design, correct site was compared...
