Abstract Purpose To investigate the feasibility and accuracy (trueness precision) of facial scanning virtual patient representation (VPR). Materials Methods One participant was recruited informed consent obtained. VPR performed 30 times with a custom fabricated intraoral scan body (ISB). Thirteen adhesive markers were added to face as an extraoral (ESB). Two scans obtained for each using infra‐red laser accessory sensor (Structure sensor; Occipital Inc) mounted on computer tablet (iPad Pro;...

Abstract Objectives: To assess the influence of psychological factors on acceptance complete dentures in a population wearing judged to be clinically satisfactory. Design: Subjects were asked personality profiles and also rate their using denture satisfaction questionnaire. Setting: The survey was conducted prosthetics clinic teaching hospital. Subjects: Patients selected from those who had new constructed department within previous two years. Intervention main outcome measures : inventory...

Abstract Purpose To evaluate the accuracy of fit metal, lithium disilicate, and zirconia crowns, which were produced using different manufacturing techniques. Materials Methods Ten patients in need a molar crown recruited. Eight crowns fabricated for each patient: 2 zirconia, 3 disilicate (e.max), metal‐ceramic conventional, conventional/digital, digital Marginal, axial, occlusal gaps measured replica technique. Replicas sectioned mesiodistally buccolingually observed under stereomicroscope....

The purpose of this article is to describe the implementation a team‐based learning (TBL) approach in removable denture prosthesis (RDP) module and present results students’ performance individual group TBL activities exam scores, experience with end course evaluations, faculty feedback. Course material at College Dentistry, University Sharjah, United Arab Emirates, was transformed into seven conventional lectures sessions. Each session consisted pre‐assigned reading (self‐directed...

The purpose of this study was to determine the methods dental practitioners in United Arab Emirates (UAE) use communicate cast removable prosthesis (RDP) design laboratories; identify common practices taken by dentists/dental technicians prior fabrication RDP framework; and seek out technicians' attitudes toward their role decisions.All laboratories (n = 28) listed a local telephone directory were invited complete questionnaire through face-to-face interview. They also requested examine...

To evaluate the effect of repetitive milling on surface roughness ceramic crowns.Twenty feldspathic crowns (VITABLOCS Mark II; Vita Zahnfabrik, Bad Säckingen, Germany) milled with hard protocol, and 20 zirconia (5Y-TZP, inCoris TZI; Dentsply Sirona, York, PA) soft using a 5-axis machine (inLab MC X5; Sirona) were investigated. Atomic force microscopy (SPM SmartSPM™-1000) was used for measurements (Ra, RMS). Pearson correlation between bur deterioration percentage as provided by software...

To evaluate and compare the fracture mode strength of monolithic zirconia to veneered metal-ceramic full-coverage restorations following artificial aging. The main concern was test performance translucent in terms load-bearing capacity.Two mandibular first molars were prepared scanned for their respective groups restorations. 75 fabricated divided into five groups: two zirconia, one group metal-ceramic. light-cured hybrid composite resin dies serve as abutments. Before cementation, all...

An in vitro experimental model was designed and tested to determine the influence that peri-implant strain may have on overall crestal bone. Strain gages were attached polymethylmethacrylate (PMMA) models containing a screw-type root form implant at sites 1 mm from resin-implant interface. Three different types of crown superstructures (cemented, 1-screw [UCLA] 2-screw abutment types) tested. Loading (1 Hz, 200 N load) performed using MTS Mechanical Test System. The gage data stored...

ABSTRACT Purpose The purpose of this study was to investigate the fracture loads and mode failure all-ceramic crowns fabricated using Top-Ceram compare it with from well-established systems: IPS-Empress II, In-Ceram. Materials methods Thirty were fabricated; 10 In-Ceram alumina Top-Ceram. Instron testing machine used measure required introduce each crown. Results Mean load for [941.8 (± 221.66) N] significantly (p < 0.05) higher than those II. There no statistically significant difference...

Powder-coated tape electrodes (powder-coated tapes) are used for doped and composite alloys welding. Using powder-coated welding of wear-resistant is stipulated by a number factors in comparison with using manual arc welding, flux cored wires, sintered tapes etc. The main task mechanized materials to keep the particles their initial condition ensure weld metal receives them quantity demanded.
