effects of liner Bonding of implant supported glass ceramic crown to zirconia abutment on bond strength and fracture resistance
Materials, 2019Co-Authors: Yongseok Jang, Sanghoon Oh, Wonsuck OhAbstract:This study was conducted to test the hypothesis that Heat-Bonding with a liner positively affects the bond strength and fracture resistance of an implant-supported glass–ceramic crown bonded to a zirconia abutment produced by a computer-aided design/computer-aided milling (CAD/CAM) procedure. Lithium disilicate-reinforced Amber Mill-Q glass ceramic blocks were bonded to 3 mol% yttria stabilized tetragonal zirconia polycrystal (3Y-TZP) blocks by Heat-Bonding with a liner or cementation with a dual-cure self-adhesive resin cement for a microtensile bond strength test. CAD/CAM implant-supported glass ceramic crowns were produced using Amber Mill-Q blocks and bonded to a milled 3Y-TZP zirconia abutments by Heat-Bonding or cementation for a fracture test. A statistical analysis was conducted to investigate the significant differences between the experimental results. The mode of failure was analyzed using high-resolution field emission scanning electron microscopy. Chemical Bonding was identified at the interface between the zirconia ceramic and liner. The mean tensile bond strength of the liner-bonded group was significantly higher than that of the cement-bonded group. The initial chipping strength of the liner-bonded group was significantly higher than that of the cement-bonded group, although no statistically significant difference was found for the fracture strength. The mode of failure was mixed with cohesive fracture through the liner, whereas the cement-bonded group demonstrated adhesive failure at the interface of Bonding.

The Production and Performance of Heat Bonded Glass Connections:: an Experimental Study
TU Delft Open, 2020Co-Authors: Eskes A.m., De Krom Diana, Bristogianni T., Rammig L.m., Veer F.a., Nijsse R.Abstract:Connecting glass with Heat bonds is a way to create all-transparent glass structures. Two methods have been researched in theory and practice, glass welding, through local Heating, and glass fusion through global Heating. Both methods have been applied to produce 10 mm thick T-sections of soda lime glass while preventing thermal shock failure and minimizing residual stress. These specimen, and specimen with an adhesive joint, have been tested destructively. It is concluded that it is possible to connect 10 mm thick soda lime glass by welding, if the glass is preHeated and the surrounding temperature remains elevated during the welding process. Additionally, glass fusion of a similar product through global Heating is possible for the applied temperature schedule. The mould has a paramount influence on the quality of the product. For both production methods, the annealing schedule was adequate to reduce residual stress. The average strength of the fused specimen was 44% larger. The standard deviation of the welded specimen was smaller: the standard deviation relative to the mean value was 9% for the welded specimen and 60% for the fused specimen. However, the amount of tested specimen is little. This research is a proof of concept for Heat Bonding soda lime glass of a structurally relevant thickness.Applied MechanicsDesign of ConstrutionStructural Design & Mechanic
