TLDR
It was found that 'slow cooling' generated the least temperature difference between inner and outer surfaces of porcelain, and 'slow cool' significantly reduced the formation of residual stress for all pressed ceramics.About:

Journal ArticleDOI
How and when does fabrication damage adversely affect the clinical performance of ceramic restorations
TL;DR: This review will examine the various types of fabrication damage inherent to each technique and attempt to establish a relationship between fabrication defects and clinical performance of all-ceramic dental restorations with particular attention to their longevity in vivo.
Journal ArticleDOI
Residual stresses in porcelain-veneered zirconia prostheses
TL;DR: The findings revealed the presence of a radial tensile stress in the overlay porcelain, which may contribute to the large clinical chip fractures observed in these prostheses.
Journal ArticleDOI
Intraoral treatment of veneering porcelain chipping of fixed dental restorations: A review and clinical application
TL;DR: In this paper, the authors compared different methods to repair fractured porcelain restorations (porcelain-fused-to-metal and all-ceramic) and explained the basic principles of adhesion in these systems.

Thermal-induced residual stresses affect the lifetime of zirconia-veneer crowns.
Renan Belli,Roland Frankenberger,Andreas Appelt,Johannes Schmitt,Luiz Narciso Baratieri,Peter Greil,Ulrich Lohbauer +6 more
TL;DR: Investigating the effects of thermal residual stresses on the reliability and lifetime of zirconia-veneer crowns showed a low sensitivity to detect reliability variations regarding thermal stresses created within the veneer layer of tested crowns.
Journal ArticleDOI
Zirconia abutments and restorations: From laboratory to clinical investigations
TL;DR: The objective of this review was to evaluate the basic science knowledge on zirconia and to discuss some aspects of the clinical behavior of zIRconia-based restorations, highlighting the possible correlation between in vitro and in vivo studies.

Introduction to Ceramics
TL;DR: In this paper, the authors present a model for the development of the MICROSTRUCTURE in CERAMICS based on phase transformation, glass formation and glass-Ceramics.

TL;DR: Zirconia offers sufficient stability as a framework material for 3- and 4-unit posterior FPDs and the fit of the frameworks and veneering ceramics, however, should be improved.
Journal ArticleDOI
Unstable cracking (chipping) of veneering porcelain on all-ceramic dental crowns and fixed partial dentures.
TL;DR: The central argument of this study is that residual stresses developed during the preparation of all-ceramic crowns and fixed partial dentures coupled with contact-induced cracking are the origin of the excessive chipping observed in clinical applications.
