TLDR
This method takes the sintering shrinkage of alumina into consideration and makes it possible to produce individual dental copings in dense-sintered, high-purity alumina, which is a biocompatible implant material.Abstract:
A method of manufacturing an all-ceramic crown composed of a coping of dense-sintered, high-purity alumina with dental porcelain is described. This method takes the sintering shrinkage of alumina into consideration and makes it possible to produce individual dental copings in dense-sintered, high-purity alumina, which is a biocompatible implant material. The alumina used has density, grain size, and flexural strength within the limits of the values required in ISO 6474-1981, 'Implants for surgery, ceramic materials based on alumina'.read more

Resin-ceramic bonding: a review of the literature.
TL;DR: Available data suggest that resin bonding to these materials is less predictable and requires substantially different bonding methods than to silica-based ceramics, and further in vitro studies, as well as controlled clinical trials, are needed.

Current ceramic materials and systems with clinical recommendations: A systematic review
TL;DR: This article reviews the current literature covering all-ceramic materials and systems, with respect to survival, material properties, marginal and internal fit, cementation and bonding, and color and esthetics, and provides clinical recommendations for their use.

A review of dental CAD/CAM: current status and future perspectives from 20 years of experience.
TL;DR: The use of dental CAD/CAM systems is promising not only in the field of crowns and FPDs but also in other fields of dentistry, even if the contribution is presently limited.

Effect of surface conditioning methods on the bond strength of luting cement to ceramics
Mutlu Özcan,Pekka K. Vallittu +1 more
TL;DR: Bond strengths of the luting cement tested on the dental ceramics following surface conditioning methods varied in accordance with the ceramic types, and hydrofluoric acid gel was effective mostly on the ceramic having glassy matrix in their structures.
