Abstract

The present invention relates to methods for the restoration of a decayed portion of an anterior tooth or re-restoration of a previously filled anterior tooth, and to dental matrices and composite resin dispensers that may be used in the methods for the restoration of a decayed portion of an anterior tooth.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for dispensing composite from a dental composite dispenser, the method comprising;
 loading a source of composite in an end section of the dispenser, the source of composite having a dispensing orifice;   attaching a hollow step down dispensing tip to the source of composite such that the step down dispensing tip is in fluid communication with the dispensing orifice of the source of composite;   heating composite in the source of composite; and   extruding the heated composite out of an exit orifice of the step down dispensing tip.   
     
     
         2 . The method of  claim 1  wherein:
 extrusion of the composite from the exit orifice of the step down dispensing tip is only practicable if the composite is heated. 
 
     
     
         3 . The method of  claim 1  wherein:
 an inside diameter of the exit orifice of the step down dispensing tip is 16% to 64% of an inside diameter of the dispensing orifice of the source of composite. 
 
     
     
         4 . The method of  claim 1  wherein:
 an inside diameter of the exit orifice of the step down dispensing tip is half or less of an inside diameter of the dispensing orifice of the source of composite. 
 
     
     
         5 . The method of  claim 1  wherein:
 an inside diameter of the exit orifice of the step down dispensing tip is in the range of about 0.4 millimeters to about 1.6 millimeters. 
 
     
     
         6 . The method of  claim 1  wherein:
 the source of composite is a capsule. 
 
     
     
         7 . The method of  claim 1  wherein:
 the source of composite is a syringe. 
 
     
     
         8 . The method of  claim 1  wherein:
 the source of composite is a chamber in the end section of the housing. 
 
     
     
         9 . The method of  claim 1  wherein:
 the composite is a paste composite including greater than 30% by volume filler. 
 
     
     
         10 . The method of  claim 1  wherein:
 the composite is a paste composite including greater than 50% by volume filler. 
 
     
     
         11 . The method of  claim 1  wherein:
 the composite is a paste composite including greater than 70% by volume filler. 
 
     
     
         12 . A method for dispensing composite from a dental composite dispenser, the method comprising;
 heating a source of composite having a dispensing orifice;   thereafter loading the source of composite in an end section of the dispenser;   attaching a hollow step down dispensing tip to the source of composite such that the step down dispensing tip is in fluid communication with the dispensing orifice of the source of composite; and   extruding the heated composite out of an exit orifice of the step down dispensing tip.   
     
     
         13 . The method of  claim 12  wherein:
 extrusion of the composite from the exit orifice of the step down dispensing tip is only practicable if the composite is heated. 
 
     
     
         14 . The method of  claim 12  wherein:
 an inside diameter of the exit orifice of the step down dispensing tip is 16% to 64% of an inside diameter of the dispensing orifice of the source of composite. 
 
     
     
         15 . The method of  claim 12  wherein:
 an inside diameter of the exit orifice of the step down dispensing tip is half or less of an inside diameter of the dispensing orifice of the source of composite. 
 
     
     
         16 . The method of  claim 12  wherein:
 the source of composite is a capsule. 
 
     
     
         17 . The method of  claim 12  wherein:
 the source of composite is a syringe. 
 
     
     
         18 . The method of  claim 12  wherein:
 the composite is a paste composite including greater than 30% by volume filler. 
 
     
     
         19 . The method of  claim 12  wherein:
 the composite is a paste composite including greater than 50% by volume filler. 
 
     
     
         20 . The method of  claim 1  wherein:
 the composite is a paste composite including greater than 70% by volume filler.
