To investigate the influence of elastic modulus mismatch between tooth and post core restorations on mechanisms root fracture.Three-dimensional mathematical models a filled maxillary premolar with supporting periodontium were constructed. The was restored cast Ni-Cr alloy or fibre-reinforced composite that bonded nonbonded to dentine. In simulation, nonlinear contact analysis executed simulate friction potential sliding phenomenon in interface core. Risks fracture debonding at estimated...
Purpose: Herein, the bond strength (BS) of denture teeth to a base resin in milled monolithic unit was investigated and compared with those 3D printed prefabricated heat-cured acrylic before after thermocycling.
The laser-beam powder-bed fusion (PBF-LB) method enables the semi-automatic fabrication of complex three-dimensional structures, making it useful for dental prostheses. However, residual stress during can cause deformation. Herein, we applied segmented-scan strategy to three-unit fixed prostheses (FDPs) and evaluated its effects on fit accuracy compared conventional methods. Three-unit FDPs consisting two abutments a pontic were fabricated using PBF-LB machine with Co-Cr-Mo powder. In group,...
Although digital removable partial dentures have been previously described, there no reports on how to fabricate them in one piece. This study proposes a new method for fabricating patient-specific using custom plate.First, gypsum model was scanned laboratory scanner and denture designed computer-aided design (CAD) software based standard tessellation language data. The metal clasp fabricated from Ti-6Al-4V 3D printer. For plate fabrication, resin frame An artificial tooth were fixed the...
Although post-heat treatment can improve the fatigue life of selective laser melting (SLM)-fabricated cobalt chromium molybdenum (CoCrMo) alloys, effect cooling conditions on properties such alloys remains unclear. In this study, we fabricated SLM CoCrMo alloy specimens and, after heat-treating them, cooled them either via furnace-cooling (FC) or air-cooling (AC). Subsequently, analyzed their microstructures using scanning electron microscopy combined with energy-dispersive X-ray...
The purpose of this study was to evaluate mechanical properties, surface characteristics and castability Zr-14Nb dental castings. mean 0.2% proof ultimate tensile strengths were approximately 68% 76% those Ti-6Al-7Nb, respectively, while they comparable Co-29Cr-6Mo. Elongation the highest all alloys tested. hardened reaction layer formed on surfaces consisted oxygen aluminum originating form investment. that Ti-6Al-7Nb. Dental castings reveal properties within range other alloys. Further...
Purpose: This study aimed to evaluate the influence of stress-relieving heat treatments on metal-ceramic bond strength and fitness accuracy selective laser melting (SLM)-fabricated Co-Cr alloy copings.
Our aim is to report an application of a prefabricated light-polymerizing plastic pattern construction removable partial denture framework without the use refractory cast. A for lingual bar was adapted on master cast mandibular Kennedy class I partially edentulous patient. The polymerized in light chamber. Cobalt–chromium wires were employed minimize potential distortion framework. carefully removed from and invested with phosphate-bonded investment subsequent casting procedures. retentive...
The artifact volume generated in magnetic resonance (MR) images was quantitatively evaluated to investigate how behavior correlates the susceptibility and of an implanted metal device. For this, a new low-magnetic-susceptibility Zr-14Nb alloy compared with two conventional dental alloys, Ti-6Al-7Nb Co-Cr-Mo alloy, using spherical specimens each prepared four different diameters. Then, MR were recorded under fast spin echo gradient conditions, from which measured. decreased susceptibility,...
Purpose: Coronavirus disease 2019 has forced the use of remote education worldwide. In 2020, authors conducted a fully digitized, flipped (RF) classroom focusing on removable partial dentures. This study aimed to evaluate learning outcomes RF and compare these with those on-site classroom.
Additive manufacturing is an emerging technology that has been successfully used in dentistry for denture fabrication. However, the conventional issue of tooth debonding exists additively manufactured dentures. In this study, we investigated physical properties teeth attached to a heat-cured base material compared tooth-coloured materials base-coloured printed monolithic unit. We designed model consisting cylindrical fabricate group and group. All groups were tested fracture load before...
