The purpose of this study was to evaluate microstructural and crystallographic phase changes after grinding 3Y-TZP dental ceramics. Ceramic blanks were sintered according to manufacturer's recommendations and divided into four groups: (A) as-sintered control, (B) diamond-ground manually under water, (C) ground and polished, and (D) ground and annealed at(More)
The purpose of this study was to investigate the effect of cerium and bismuth coloring salts solutions on the microstructure, color, flexural strength, and aging resistance of tetragonal zirconia for dental applications (3Y-TZP). Cylindrical blanks were sectioned into disks (2-mm thick, 25-mm in diameter) and colored by immersion in cerium acetate (CA),(More)
PURPOSE This in vitro study evaluated the 3D and 2D marginal fit of pressed and computer-aided-designed/computer-aided-manufactured (CAD/CAM) all-ceramic crowns made from digital and conventional impressions. MATERIALS AND METHODS A dentoform tooth (#30) was prepared for an all-ceramic crown (master die). Thirty type IV definitive casts were made from 30(More)
STATEMENT OF PROBLEM No studies have evaluated the internal adaptation of pressed and milled ceramic crowns made from digital impressions. PURPOSE The purpose of this in vitro study was to evaluate the internal fit of pressed and milled ceramic crowns made from digital and conventional impressions. MATERIAL AND METHODS Thirty polyvinyl siloxane (PVS)(More)
This in vitro study compared the retentive ability of 11 materials used to cement cast crowns on one implant system. The crowns were cemented to the abutments and the tensile load necessary to remove each casting was measured 30 minutes after cementation in a dry condition at 22 degrees C and after storage for 72 hours in saline solution at 37 degrees C.(More)
PURPOSE Several complications may arise in patients wearing complete prosthetic appliances, including denture-associated infections and mucosal stomatitis due to Candida species. This study evaluated the activity of anti-Candida agents in denture adhesive and the cytotoxicities of these preparations for primary human gingival epithelial (GE) keratinocytes.(More)
The purpose of this study was to evaluate the effect of magnesium content on the microstructure and crystalline phases of glass-ceramics in the system SiO(2)-MgO-CaO-Na(2)O-K(2)O-F. Four glass compositions were prepared with magnesium content varying from 12-18 wt%. The compositions were melted at 1400 degrees C for 2 h and cast into 30 x 8 mm ingots.(More)
Osseointegrated implant support of dental restorations continues to be a popular option for the contemporary patient with missing natural dentition. This article focuses on the two most frequently used methods for attaching final prostheses to endosseous implants. The authors offer practical solutions for minimizing implant screw loosening and describe the(More)
PURPOSE The purpose of this study was to investigate the prosthetic complications of patients with a maxillary complete removable dental prosthesis opposing a mandibular metal-resin implant fixed complete dental prosthesis. MATERIALS AND METHODS This study is a retrospective analysis of an ongoing prospective study. Dental records from 46 patients treated(More)
