Dental Dentin Bonding System
US Patent:
5639239, Jun 17, 1997
Filed:
Jan 12, 1995
Appl. No.:
8/372036
Inventors:
Jeffrey O. Earle - Milford DE
International Classification:
A61C 508
US Classification:
433218
Abstract:
A method and system for attaching, for example, an artificial dental prosthetic device such as a crown, cap, or bridge to a prepared tooth structure utilizes a fluoride releasing dentin bonding system in combination with a cement layer. The dentin bonding system is first applied to the prepared tooth structure, the dentin bonding system including a primer layer and a VLC microfill composite resin layer in certain embodiments. Then the artificial prosthetic device (e. g. crown) is removably adhered to the prepared tooth structure and the dentin bonding system by way of the cement (e. g. zinc oxide based type). The cement layer sandwiched between the attached device and the dentin bonding system has a shear function less than that of the device and the dentin bonding system but sufficient to permanently bond the device to the tooth and dentin bonding system during masticatory functions and demands, thereby permitting the device to be removed or sheared from the tooth (and dentin bonding system) without destroying either. Thus, the artificial prosthetic device can be removed from the prepared tooth structure in the event that the need to do so arises (e. g. if non-functionality during mastication occurs or if endodontic responses develop).
Teflon-Coated Intraoral Tissue Retraction Cord
US Patent:
5540588, Jul 30, 1996
Filed:
Nov 2, 1994
Appl. No.:
8/334030
Inventors:
Jeffrey O. Earle - Milford DE
International Classification:
A61C 514
US Classification:
433136
Abstract:
A dental retraction cord (or tape) for placement between a tooth and its adjacent gum tissue during dental impression taking and restorative procedures includes a thermoplastic material such as polytetrafluoroethylene (i. e. PTFE or Teflon) so that the cord is resistant to shredding, tearing, and sticking to dental restorative and impression taking materials. Additionally, chemical treatment of the cord may be avoided so as to reduce the risk of harmful side effects in chemically sensitive patients.
