Comparison of marginal fit of cemented zirconia copings manufactured after digital impression with lava™ C.O.S and conventional impression technique
BACKGROUND Evaluation of the marginal fit of cemented zirconia copings manufactured after digital impression with Lava™ Chairside Oral Scanner in comparison to that of zirconia copings manufactured after conventional impressions with polyvinyl siloxane. METHODS A prepared typodont tooth #36, was replicated 40 times with a vinyl silicone and precise model resin. The dies were randomly divided ...
متن کاملThe effect of various veneering techniques on the marginal fit of zirconia copings
PURPOSE This study aimed to evaluate the fit of zirconia ceramics before and after veneering, using 3 different veneering processes (layering, press-over, and CAD-on techniques). MATERIALS AND METHODS Thirty standardized zirconia CAD/CAM frameworks were constructed and divided into three groups of 10 each. The first group was veneered using the traditional layering technique. Press-over and C...
متن کاملLess Light Transmitted Through Zirconia Copings Translucency of Zirconia Copings Made With Different
Background: There is increased use of all-ceramic crowns in place of ceramo-metal crowns in restorative practices. The difference in properties of different ceramics will affect the final esthetics of the restoration, and we need to consider this, especially when restoring anterior teeth. This article compares and analyzes translucency levels of different zirconia-based ceramic CAD/CAM systems....
متن کاملMarginal and Internal Fit of CAD/CAM and Slip-Cast Made Zirconia Copings
BACKGROUND AND AIMS CAD/CAM systems facilitate the use of zirconia substructure materials for all-ceramic copings. This in vitro study investigated the marginal and internal fit of zirconia copings made with CAD/CAM system and slip-casting method. MATERIALS AND METHODS Sixteen CAD/CAM made zirconia copings and 16 slip-cast made zirconia copings were fabri-cated and cemented with glass-ionomer...
متن کاملMarginal and internal fit of zirconia copings obtained using different digital scanning methods.
The objective of this study was to evaluate the marginal and internal fit of zirconia copings obtained with different digital scanning methods. A human mandibular first molar was set in a typodont with its adjacent and antagonist teeth and prepared for an all-ceramic crown. Digital impressions were made using an intraoral scanner (3Shape). Polyvinyl siloxane impressions and Type IV gypsum model...
