System For Fabrication Of Indirect Dental Restoratives
US Patent:
6386865, May 14, 2002
Filed:
Aug 10, 1999
Appl. No.:
09/371737
Inventors:
Byoung I. Suh - Oak Brook IL
Patrick L. Roetzer - Benicia CA
Rich Nagel - West Chicago IL

Assignee:
Bisco Inc. - Schaumburg IL
International Classification:
A61C 100
US Classification:
433 27, 433223, 264 16
Abstract:
A process for the fabrication of indirect dental restoratives includes the making of a first, pre-operative impression of a tooth to be restored using a first polyvinyl silicone (PVS) material disposed in a clear tray, followed by the preparation of the tooth. A second, final post-operative impression of the tooth is taken utilizing a second PVS material. A tooth model is then made by pouring a low viscosity and suitably rigid, third PVS material into the final impression. Prior to the complete setting of the low viscosity PVS material, a higher viscosity, fourth PVS material is applied onto the model PVS material to form a completed model with base. The model is then fitted into the pre-operative impression matrix made from the first PVS material. Layers of composite are packed onto the impression in the clear matrix. The model (with attached base) is then inserted into the composite disposed in the first PVS material and the resulting matrix is placed in a single apparatus for conducting both light and heat cure of the dental composite.

Dental Retractor And Fluid Control System
US Patent:
6752630, Jun 22, 2004
Filed:
Apr 9, 2002
Appl. No.:
10/120318
Inventors:
Patrick L. Roetzer - Benicia CA 94510
International Classification:
A61C 500
US Classification:
433140, 600242
Abstract:
A dental retractor system used to manipulate positioning of the cheeks and to control saliva flow. The system includes a handle connected to first and second legs that are extended from the handle in a fork or horseshoe configuration. A pair of flaps distend from the legs and are angularly arranged to lie adjacent inner cheeks of the patient with or without interaction with a dry angle.
Dental Impression Dam System
US Patent:
6817861, Nov 16, 2004
Filed:
Apr 9, 2002
Appl. No.:
10/120292
Inventors:
Patrick L. Roetzer - Benicia CA 94510
International Classification:
A61C 900
US Classification:
433 37, 433 38
Abstract:
A dental impression dam system utilizing an open tray forming a basin for dental impression material. The basin of the tray includes a gap at an extremity of the same. A flexible band of material bridges the gap of the tray basin and interacts with the dental material to form unit. The band adheres to the external wall portions of the tray when in place.
Rapid Adapting Precision Transformer For Occlusal Resins
US Patent:
5779476, Jul 14, 1998
Filed:
Apr 30, 1997
Appl. No.:
8/846793
Inventors:
Patrick Roetzer - Benicia CA
Ron Verner - Scottsdale AZ
Ron Verner - Scottsdale AZ
International Classification:
A61C 306
US Classification:
433166
Abstract:
A self-limiting dental composite restoration sculpting bur particularly adapted for sculpting occlusal resins. Because of the cuspal angle of its cutting surface, the bur will make cuts that closely match the naturally occurring topography of human teeth as well as provide a visual stop that indicates when the desired cutting depth has been reached. The apparatus also includes a diamond coated cutting surface that is of such a roughness that it creates a physical stop that sends a tactile response to the operator when the bur contacts enamel. This tactile response ensures that the operator can avoid overcutting the restoration. In addition, a non-diamond coated annular band can be provided on the cutting head to create a safe zone which serves a further limit stop. The bur is mounted on a straight shaft to allow maximum vertical adjustment when mounted to a standard dental drill. The advantages include a visual depth stop, a physical stop, a shape that matches naturally occurring topography, and using a straight shaft to maximize vertical adjustability.

Dental Bur
US Patent:
6902400, Jun 7, 2005
Filed:
Oct 18, 2002
Appl. No.:
10/274568
Inventors:
Patrick L. Roetzer - Benicia CA, US
International Classification:
A61C003/02
US Classification:
433165, 606 80, 408200
Abstract:
A dental bur structure including a rotatable shaft turned by a motor. The shaft possesses a proximal portion having a fluted surface. The bur also possesses a distal portion with a smooth surface tip which generates heat to melt a composite post matrix upon activation of the shaft. The fluted surface removes a composite material while the smooth tip serves as a guide for the bur.
