Intra oral photogrammetry: trueness evaluation of novel technology for implant ...
Pozzi, Alessandro; Laureti, Andrea; Tawil, Isaac; Chow, James; Azevedo, Luis; Fehmer, Vincent; Sailer, IrenaObjectives: To investigate the trueness of intraoral photogrammetry (IPG) technology for complete-arch implant digital impression and evaluate the effect of implant number. Material and Methods: All data were fully anonymized in compliance with ethical standards, and a total of 30 complete-arch patient models with 4 (n = 13), 5 (n = 9), or 6 (n = 8) implants were selected from the archive. Digital impressions w...
Influence of horizontal intraoral scan bodies on the trueness of digital impres...
Laureti, Andrea; Marques, Tiago; Pitta, João; Fehmer, Vincent; Sailer, Irena; Pozzi, Alessandro; Azevedo, LuísObjective: To assess the impact of horizontal intraoral scan bodies (H-ISBs) on the trueness of complete-arch digital impressions compared to vertical ISBs (V-ISBs). To evaluate trueness among four intraoral scanners (IOS) and inter-operator variability across different ISB × IOS combinations. Materials and Methods: Digital impressions were made from a dental cast with four multi-unit analogs using four H-ISBs:...
Effect of splinting scan bodies on the trueness of complete-arch digital implan...
Azevedo, Luís; Marques, Tiago; Karasan, Duygu; Fehmer, Vincent; Sailer, Irena; Correia, André; Gómez-Polo, MiguelStatement of problem: The absence of fixed reference points can affect the trueness of complete-arch intraoral digital implant scans. The effect of splinting intraoral scan bodies (ISBs) or the inclusion of artificial landmarks (AL) on the trueness of complete-arch digital implant scans is still unclear. Purpose: The purpose of this study was to analyze the effect of splinting ISBs or the inclusion of AL on the...
Staining and aging-dependent changes in color of CAD-CAM materials
Stamenković, Dejan D.; Tango, Rubens Nisie [UNESP]; Todorović, Ana; Karasan, Duygu; Sailer, Irena; Paravina, Rade D.Made available in DSpace on 2021-06-25T10:35:19Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01; Statement of problem: Consumption of some beverages and aging may affect the color of dental materials used in fixed prosthodontics, but their effect on recently introduced materials is not well known. Purpose: The purpose of this in vitro study was to evaluate staining, aging, and the exposure interval...
Effect of Staining and Aging on Translucency Parameter of CAD-CAM Materials
Tango, Rubens Nisie [UNESP]; Todorovic, Ana; Stamenkovic, Dejan; Karasan, Duygu Narin; Sailer, Irena; Paravina, Rade DusanMade available in DSpace on 2021-06-25T15:02:48Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-03-01; Objectives: To evaluate different intervals of exposure to staining solutions and artificial aging on translucency parameter (TP00) of CAD-CAM materials. Material and Methods: One millimeter thick square-shaped specimens (N = 288) were cut from Cerasmart (CS), IPS e.max OE), Lava Ultimate (LU), Shofu HC...
