US Patent:
5705273, Jan 6, 1998
Filed:
Mar 8, 1995
Appl. No.:
8/400362
Inventors:

Assignee:

International Classification:
B32B 1700, C03C 1700, B05D 302, B05D 310
US Classification:

Abstract:
A method for strengthening and increasing the thickness of the strengthened surface layer of a dental ceramic restorative material where the ceramic material is heat treated with a salt composition containing a lithium ion and a metal ion larger than the lithium ion first at a temperature above the strain temperature followed by a second heat treatment with the salt composition at a temperature below the strain temperature. The treatment is especially effective for all-ceramic, high-leucite feldspathic porcelain restorations.
Dental Drill Alignment Indicator
US Patent:
4824367, Apr 25, 1989
Filed:
Oct 17, 1986
Appl. No.:
6/920000
Inventors:
Stephen F. Rosenstiel - Worthington OH
Edwin R. I. Deane - London, GB2
Edwin R. I. Deane - London, GB2
Assignee:
National Research Development Corporation - London
International Classification:
A61C 300
US Classification:
433 75
Abstract:
In dental surgery when a tooth is to be crowned, the tooth has to be prepared by cutting a taper. It has been found that for the successful mounting of a crown the taper must be much more exactly prepared than is possible using currently available equipment. The present invention allows the initial position of the axis of a cutter to be related by means of electronic "spirit levels" to a selected axis. Deviation from this axis by more than a predetermined amount is indicated by light sources which can be seen regardless of the position of a handpiece holding the cutter. By means of a code these light sources indicate how the dentist must move the cutter to return to the correct axis.
