Abstract
An In-situ Tooth Filling System and Method Utilizing External Curing Step. The method and system utilizes the heat-/light-/vacuum-curing process normally available only in a dental laboratory. Like the conventional dental prosthetic production process, the filling is attached to the tooth void utilizing curable cement. Unlike the conventional (indirect) method, however, the instant method is completed totally within a single appointment in the dentist's office. The system utilizes fill stems that are made from curable filling material. These stems will become a part of the filling when the filling is cured. The filling is partially cured and then removed from the tooth for final curing in a vacuum oven that heat- and/or light-cures the filling.
Claims18
A method for repairing a tooth, comprising the steps of:
- creating a void in the tooth by removal of a portion of the tooth;
- inserting a first end of a hollow stem into said void;
- injecting filling material into said void by injecting said material in non-solid form into a second end of said hollow stem and out through said first end until said void is completely filled with said non-solid filling material;
- first curing said filling material in said stem and said void to form a partially cured prosthetic assembly;
- removing said partially cured prosthetic assembly from said tooth;
- second curing said prosthetic assembly;
- and
- re-inserting said prosthetic assembly into said void formed in said tooth.
A tooth filling system, comprising:
- a reservoir of non-hardened filling material;
- a dispenser nozzle extending from said reservoir for dispensing said filling material therethrough;
- a sacrificial stem for inserting a distal end of said nozzle into a second end thereof, said sacrificial stem formed from substantially the same material as said filling material, but in a hardened form.
A method for installing a dental prosthetic into a void formed in a tooth, comprising the steps of:
- inserting a first end of a hollow stem into said void;
- injecting filling material into said void by injecting said material in non-solid form into a second end of said hollow stem and out through said first end until said void is completely filled with said non-solid filling material;
- first curing said filling material to form a partially cured prosthetic assembly;
- removing said partially cured prosthetic assembly from said void;
- second curing said prosthetic assembly;
- and
- re-inserting said prosthetic assembly into said void formed in said tooth.
