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.
An occlusal-incisal dental carving instrument comprising a handle and a flattened head carried by said handle, the head terminating in a concave distal edge and having a pair of concave side edges, the longitudinal direction of said side edges being substantially perpendicular to the longitudinal direction of said distal edge, the length of said distal and side edges being substantially the same, said distal and side edges utilized for carving of a dental restoration on the occlusal surface of a tooth.
A method of external carving, contouring, and finishing a dental restoration of a human tooth, the method comprising the following steps:
