Influence of Sandblasting and Chemical Etching on Titanium 99.2-Dental Porcelain Bond Strength.

Materials (Basel, Switzerland)

Lubas M, Jasinski JJ, Zawada A, Przerada I.
PMID: 35009263
Materials (Basel). 2021 Dec 24;15(1). doi: 10.3390/ma15010116.

The metal-ceramic interface requires proper surface preparation of both metal and ceramic substrates. This process is complicated by the differences in chemical bonds and physicochemical properties that characterise the two materials. However, adequate bond strength at the interface and...

Shade variance in ceramic restoration and shade tab: An in vitro study.

Journal of pharmacy & bioallied sciences

Prabu PS, Prabu NM, Kumar M, Abhirami M.
PMID: 23066235
J Pharm Bioallied Sci. 2012 Aug;4:S139-41. doi: 10.4103/0975-7406.100218.

BACKGROUND: In clinical practice aesthetics for any restoration needs to consider the parameters of surface form, translucency and colour. To achieve ideal aesthetics the colour replication process for dental porcelain is the most important step which comprises of a...

Surface treatment of feldspathic porcelain: scanning electron microscopy analysis.

The journal of advanced prosthodontics

Valian A, Moravej-Salehi E.
PMID: 25352961
J Adv Prosthodont. 2014 Oct;6(5):387-94. doi: 10.4047/jap.2014.6.5.387. Epub 2014 Oct 21.

PURPOSE: Topographic analysis of treated ceramics provides qualitative information regarding the surface texture affecting the micromechanical retention and locking of resin-ceramics. This study aims to compare the surface microstructure following different surface treatments of feldspathic porcelain.MATERIALS AND METHODS: This...

Fatigue studies of high-palladium dental casting alloys: Part II. Transmission electron microscopic observations.

Journal of materials science. Materials in medicine
