ABSTRACT:
A dental restorative pin is provided in three sequential sections, the first intended to penetrate into and to engage in a dentinal pin-hole having a hemispherical indentation surrounding its opening, a second section having a sealing surface curved on a hemispherical locus for mating with the hemispherical indentation when the first section penetrates into said pin-hole, to seal the opening, and to limit penetration of the first section into the pinhole, and the third section extending supragingivally from the second and being embeddable in a surrounding body of restorative material. Means is provided to form an annular open zone surrounding the junction of the first and second sections when the first section is engaged in the pin-hole and the sealing surface of the second section is mated to the hemispherical indentation.
