Abstract Objectives The aim of Working Group 3 was to focus on three topics that were assessed using patient‐reported outcome measures ( PROM s). These included the following: (a) aesthetics tooth and implant‐supported fixed dental prostheses focusing partially edentulous patients, (b) a comparison removable implant‐retained for populations, (c) immediate versus early/conventional loading immediately placed implants in edentate patients. s include ratings satisfaction oral health‐related...
Abstract Objectives New generation intraoral scanners are promoted to be suitable for digital scans of long-span edentulous spaces and completely arches; however, the evidence is lacking. The current study evaluated accuracy scanning (IOS) in partially arch models analyzed influence operator experience on accuracy. Materials methods Four different resin (completely maxilla mandible) were scanned, using a new IOS device ( n = 20 each). Ten each model performed by an IOS-experienced...
The primary aim of this in vitro study was to evaluate the influence alveolar ridge morphologies on accuracy static Computer-Assisted Implant Surgery (sCAIS). secondary aims were guide-hole design and implant macro-design final position.Eighteen standardized partially edentulous maxillary models with two different types used. Each model scanned via cone beam computer tomography prior placement a laboratory scanner following using sCAIS. postsurgical scans superimposed initial treatment...
: To measure the impact of superimposition methods and designated comparison area on accuracy analyses dentate models using an ISO-recommended 3-dimensional (3D) metrology-grade inspection software (Geomagic Control X; 3D Systems; Rock Hill, South Carolina; USA). A maxillary typodont scanned with a desktop scanner (E4; 3 Shape; Copenhagen; Denmark) intraoral (Trios 4; was used as reference. Eight groups were created based core features each method: landmark-based alignment (G1); partial...
To evaluate how restoration thickness (0.5 mm and 0.7 mm) affects the fabrication trueness of additively manufactured definitive resin-based laminate veneers, to analyze effect margin location on quality.
The information in the literature on effect of printing layer thickness interim 3D-printed crowns is limited. In present study, trueness and margin quality composite resin was investigated compared with milled crowns. were printed 3 different thicknesses (20, 50, 100 μm) by using a hybrid based acrylic esters inorganic microfillers or from polymethylmethacrylate (PMMA) discs digitized an intraoral scanner (test scans). compare tool 3D analysis software used to superimpose test scans...
To evaluate a nonmetrology-grade and metrology-grade 3D analysis software when measuring the deviations of computer-aided-design/ computer-aided-manufacturing (CAD-CAM) fabricated crowns from virtual design file.A right first molar on mandibular dentate model was prepared scanned with an intraoral scanner, i500 (Medit). A complete coverage crown designed in standard tessellation language (STL) format 20 resin were CAD-CAM. The then digitized using same scanner (test-scans). Root mean square...
Three-dimensional printing has facilitated the fabrication processes in dentistry. However, knowledge on effect of layer thickness trueness 3D printed fixed partial dentures (FPDs) is lacking.
To investigate the effect of 3-dimensional (3D) analysis software and operator on measured deviations in implant scans.A combined healing abutment-scan body (CHA-SB) system was digitized with an industrial scanner (ATOS Core 80) to generate a master standard tessellation language file (MRM-STL) intraoral (TRIOS 3) 9 test-scan STL files, which were transferred into metrology-grade (Geomagic Control X, GX GOM Inspect, GM) nonmetrology-grade (Medit Link, ML) for deviation analysis. Test-scan...
Abstract Purpose To evaluate the flexural strength and Vickers microhardness of different CAD‐CAM denture base materials. Materials methods Sixty rectangular specimens (64 × 10 3.3 ± 0.2 mm) were fabricated from 3 materials (G‐CAM, Graphene‐reinforced polymethylmethacrylate, GC), Ivotion Base (Prepolymerized IV), Denturetec (3D‐printed resin, DT) either by using additive (DT) or subtractive manufacturing (IV GC). Specimens each group divided into 2 subgroups (thermal cycled nonthermal...
Abstract Objectives The aim of Working Group 4 was to address patient benefits associated with implant dentistry. Focused questions on (a) dental patient‐reported outcomes (dPROs), (b) improvement in orofacial function, and (c) preservation tissues partially fully edentulous patients following provision implant‐retained/supported prostheses were addressed. Materials Methods Three systematic reviews formed the basis for discussion. Participants developed statements recommendations determined...
To evaluate the surface roughness, optical properties, and microhardness of additively or subtractively manufactured CAD-CAM materials after simulated brushing coffee thermal cycling.Two resins (Crowntec, CT VarseoSmile Crown Plus, VS) 3 (a reinforced composite (Brilliant Crios, BC), a polymer-infiltrated ceramic network (Enamic, VE), feldspathic (Mark II, VM)) were used to fabricate disk-shaped specimens (Ø10×1-mm) (n = 10). Surface Vickers microhardness, color coordinates measured...
To compare the in vitro scan accuracy (trueness and precision) of recently introduced wireless intraoral scanners (IOSs) to commonly used wired IOSs different fixed partial denture (FPD) situations. Three partially edentulous maxillary models with implants located at sites (lateral incisors [Model 1]; right canine first molar 2]; premolar 3]) were digitized (Primescan 2 [P2] TRIOS 5 [T5]) [P1] 3 [T3]) (n = 14 per IOS-model pair). The also an industrial-grade optical scanner for their...
The primary aim of this in vitro study was to investigate the implant stability obtained immediate and late placement scenarios. Secondary aims evaluated effect two distinct macro-designs examined correlation between resonance frequency analysis (RFA) final insertion torque. Partially edentulous maxillary models including six single sites simulating extraction sockets healed alveolar ridges were used. Virtual planning facilitated static computer-assisted bone level implants with either a...
Statement of problemStudies on the microhardness novel additively manufactured polymers compared with well-established low- and high-viscosity composite resins regard to chemical composition are lacking.PurposeThe purpose this in vitro study was evaluate effect hydrothermal aging various conventional polymers.Material methodsCylindrically shaped specimens (N=240, n=10 per group) (Ø10×2 mm) were either (6 groups) or conventionally by using 3D (Optiprint Temp [OP; Dentona]; C&B MFH [ND;...
