Dental ceramics—an update

Journal of Dentistry, 1990
The application of certain industrial ceramics and processing techniques has facilitated the introduction of a wide range of new dental restorative products including castable glass-ceramics, shrink-free materials and an ion-strengthening paste. However, these recent advances must be evaluated against the well-established materials and techniques ...

Demystifying Modern Dental Ceramics

Primary Dental Journal, 2019
With increasing patient expectation for aesthetic dental restorations, there has been a drive towards developing ceramic materials to meet this expectation. Multiple ceramic systems have been introduced over the past four decades with considerable advances in material properties.

Some properties of dental ceramics

Journal of Oral Rehabilitation, 1975
SummaryThe rather exacting aesthetic requirements of dental restorations has largely dictated the composition of dental ceramic materials. The so‐called dental porcelains have evolved from the traditional whiteware formula of feldspar, clay and quartz. One of the first variables which might be considered is that of chemical composition. It is, however,

Polishing systems for dental ceramics

Acta Odontologica Scandinavica, 1993
The increasing use of ceramic crowns and inlays in posterior teeth has highlighted the clinical difficulties involved in achieving a good surface finish after corrective grinding. In the present work several polishing systems and techniques were compared, initially using only one dental ceramic, Vita Mark I.

Degradability of Dental Ceramics

Advances in Dental Research, 1992
The degradation of dental ceramics generally occurs because of mechanical forces or chemical attack. The possible physiological side-effects of ceramics are their tendency to abrade opposing dental structures, the emission of radiation from radioactive components, the roughening of their surfaces by chemical attack with a corresponding increase in ...

The strength of dental ceramics

Journal of Dentistry, 1991
Considerable changes have taken place in the range of ceramic materials available for dental use. Although the appearance of dental porcelain is good and biocompatibility excellent, its mechanical properties are somewhat limited. As a consequence, a number of distinct developments have taken place primarily to achieve greater strength; other goals ...

Side-Effects of Dental Ceramics

Advances in Dental Research, 1992
Evaluation of side-effects to low-dose exposure of any agent is difficult, especially if the agent exhibits a low toxicity. The most common way to approach such evaluation is to define special groups which are exposed more than others. Studies of such risk groups may facilitate interpretation of information related to those exposed to a low dose.

CERAMIC DENTAL IMPLANT

2003
The invention relates to a dental implant comprising an anchor part (12) for anchoring said implant in the bone and a mounting part (18) for receiving a prosthetic superstructure. According to the invention, the anchor part (12) and the mounting part (18) are configured in one piece from a zirconium oxide-based material and at least sections of the ...

Degradation of Dental Ceramics

2013
Orthodontic appliances and dental ceramics are installed within the oral cavity and this environment presents a series of external factors that can influence the mechanical and physical properties of these devices. The environment of the oral cavity aggravates the low tensile strength of dental ceramics.
