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.
