Investigation of the Bond Strengths of Dental Porcelain Fused to Titanium

摘要

In the early part of the 18th century, Fauchard the father of dentistry, proposedthe use of porcelain for making artificial teeth. Since that time, work has never ceased on this fascinating material; and has lead to the highly sophisticated ceramics that are being used today (McLean, 1991). Over the past 25 years, the development of metal ceramic technology has lead to almost universal acceptance of metal-ceramic systems for the fabrication of fixed partial dentures (Campbell, 1989). Biological concerns over existing restorative metal alloys have led researchers to study titanium as an alternate due to its biocompatibility. Titanium is a key metal used by high technology industries, as well as dentistry. Titanium plays a major role in the replacement of the root portion of a tooth; but, also in the replacement of the coronal portion of the tooth (Chance, 1992).
