ABSTRACT:
The finishing of dental restorations is disclosed with use of dental instruments of the present invention including instruments having concave surfaces shaped to conform to external convex tooth anatomy. External carving and contouring is accomplished by first carving the distal, mesial, lingual and facial convex surfaces using an interproximal carving instrument of the present invention, followed by carving of adjacent marginal ridges and contact areas, and embrasures with an intermarginal carver. Internal carving and contouring is accomplished by first making the areas of fossae and basic occlusal grooves with the ball end of the intermarginal carver, followed by carving and contouring tooth cusps and cuspal inclines, and then supplemental or developmental grooves with an occlusal-incisal carver.
