High impact information on Laboratories, Dental

• Experimental. Wedges and molar crowns were hand-waxed and investment cast in commercial purity grade 1 (CP-1) titanium by a commercial dental laboratory [1].
• CONCLUSIONS: Except for In-Ceram Alumina, Vitadur Alpha and Zirconia-TZP core ceramics, most of the investigated ceramic materials fabricated under the condition of a dental laboratory were not stronger or more structurally reliable than Vita VMK 68 veneering porcelain [2].
• OBJECTIVES: To assess the height of occlusal registration blocks made in dental laboratories compared with recommended dimensions [3].
• Exposure to methyl methacrylate (MMA), total dust and health symptoms were investigated in 20 dental laboratories located in Tehran, Iran. Time-weighted average (TWA) of MMA and peak concentrations were determined, using XAD-2 tubes followed by GC-FID analysis [4].
• Specimens for mechanical testing were prepared by adding composites powder (PMMA, BPO and HA) to the monomer (MMA and EGDMA) followed by hand mixing as in dental laboratory description usage [5].

Associations of Laboratories, Dental with chemical compounds

• Evaluation of exposure to methyl methacrylate among dental laboratory technicians [6].
• Protocols for essential treatment and precautions for personnel working in dental laboratories where hydrofluoric acid is used have been discussed [7].
• Mercury vapor levels in a dental laboratory [8].
• The general workroom air of eleven dental laboratories has been surveyed with respect to dust levels arising from cutting, grinding or polishing various dental materials like chromium-cobalt-, nickel- or gold alloys, amalgam and gypsum models, porcelain or denture base material [9].
• The Spring-Bow instrument was selected for use by dental students at the Medical University of South Carolina College of Dental Medicine because its simplicity facilitates teaching and its versatility fosters continued routine use and cooperation with the dental laboratory [10].

Gene context of Laboratories, Dental

• Productivity: the key to profitability in a dental laboratory. Part one [11].
• The CAD/CAM abutment required no further customization in the dental laboratory [12].
• MATERIALS AND METHODS: A total of 2,069 sintered feldspathic ceramic restorations (Colorlogic) and 1,136 pressure-molded ceramic restorations (IPS Empress 1 and 2) were produced during the study period by one dental laboratory [13].
• The North American Free Trade Agreement: will it affect the dental laboratory industry [14]?

Analytical, diagnostic and therapeutic context of Laboratories, Dental

• SIGNIFICANCE: The coupling of laser digitizing and RP indicates a potential to replace the traditional 'impression taking and waxing' procedure in dental laboratory, with the quality of the cast titanium prostheses also being improved by using the numerically optimized runner and gating system design [15].
• METHODS: Since 1988 more than 10,000 cast titanium units of crowns and fixed partial dentures have been produced by the only dental laboratory that produces cast titanium restorations in Norway [16].
• Due to the relative simplicity involved in development of a lingualized occlusal scheme by dental laboratory technicians, this approach has gained favor among practitioners who are able to evaluate and/or correct tooth arrangements for complete dentures [17].
• Introduction to orthodontics to a full-service dental laboratory, Part II. Fabrication of a space maintainer [18].
