This study evaluated the effects of differences in printing directions stereolithography (SLA) three-dimensional (3D)-printed dentures on accuracy (trueness and precision). The maxillary denture was designed using computer-aided design (CAD) software with an STL file (master data) as output. Three different (0°, 45°, 90°) were used. Photopolymer resin 3D-printed (n = 6/group). After scanning all dentures, data saved/output files (experimental data). For trueness, experimental superimposed...
This study evaluated the influence of illuminance and color temperature ambient light on trueness, precision, scanning time a digital impression.Master data were acquired with high-accuracy coordinate-measuring machine. The was set at 0lux, 500lux, 2500lux light-emitting diode (LED). Using conversion filter, 3900 Kelvin (K) (yellow), 4100K (orange), 7500K (white), 19,000K (blue). There thus total 12 possible lighting conditions. reference model scanned five times under each condition by an...
This study compared the mechanical properties and molecular distribution of a polymethyl methacrylate (PMMA) block (Dry) with specimens that were fabricated by conventional method cured in wet environment (Control). Two specimen types heat-curing denture base resin. Dry polymerized at high pressure dry system, while Control method, accordance manufacturer’s recommended procedures. Specimens from each group evaluated for three-point bending, water sorption solubility, color change, gel...
In this study, the physical properties of a custom block manufactured using self-polymerizing resin (Custom-block), commercially available CAD/CAM PMMA disk (PMMA-disk), and heat-polymerizing (Conventional PMMA) were evaluated via three different tests. The Custom-block was polymerized by pouring into special tray, Conventional with heat-curing method, according to manufacturer’s recommended procedure. specimens each group subjected three-point bending, water sorption solubility, staining...
Photopolymer resins are widely used in the production of dental prostheses, but their mechanical properties require improvement. We evaluated effects different zirconia filler contents and printing directions on photopolymer resin. Three-dimensional (3D) was to fabricate specimens using composite photopolymers with 0 (control), 3, 5, 10 wt.% filler. Two for fabricating rectangular (25 mm × 2 mm) disk-shaped (φ10 were used, 0° 90°. Three-point bending tests performed determine flexural...
Individuals who are edentulous have a lower intake of fruit, vegetables, fiber, and protein compared with their dentate counterparts because tooth loss is accompanied by decrease in ability to chew. Whether or not combination prosthetic rehabilitation simple dietary advice produces improvement among persons unclear. We aim investigate the effect simultaneous delivered dentists provision new complete dentures on individuals request dentures. Through double-blinded, parallel, randomized...
This in vitro study investigates the effect of different post-rinsing times and methods on trueness precision denture base resin manufactured through stereolithography.Ninety clear photopolymer specimens were fabricated divided into nine groups (n = 10) based rinsing methods. All rinsed with 99% isopropanol alcohol for 5, 10, 15 min using three methods-automated, ultrasonic cleaning, hand washing. The polymerized 30 at 40℃. For trueness, scanned intaglio surface each SLA was superimposed...
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...
Purpose: Additive manufacturing has revolutionized the fabrication of complete dentures. However, this process involves support structure, which is a construction part that holds specimen during printing, and may prove to be disadvantageous. Therefore, in vitro study compared effect structure reduction on various volume area distributions 3D-printed denture base determine optimal parameters based accuracy.
Abstract Background Metabolic syndrome (MetS), caused by the accumulation of visceral fat, is considered a major cause cardiovascular disease. This randomized controlled trial aimed to clarify effect dental intervention, including prosthodontics and/or periodontal treatment, combined with dietary and exercise guidance on MetS. Methods In total, 112 patients who met Japanese waist circumference criteria MetS were recruited. The intervention group (ITG) received along guidance, while control...
