Abstract

Piece prosthetic dental fixed preformed for total covering teeth type of crowns completas, which essentially is characterized by an external configuration chord with the anatomy of a crown tooth and internally is hollow configuration cylindrical or conical communicating by the base overseas. It is polyhedral shape with six faces entire surface is curved, separated edges by these difficult romas delimitation. Your mouth as described in placement. The upper face, call oclusas, incisal o masticatory (fig. 1-a), presents elevations or cuspide (fig. 2-k), for piramides quadrangular separate furrow converging in pits and presenting at its front end o mesial and subsequent o distal ridges, flanges marginal (fig. 2-a). The underside or cervical (fig. 1-f), has an opening that leads to a compartment or frusto-cylindrical hollow, to house the prepared tooth stump. Two sides are proximal, mesial (fig. 1-b), which contacts the before and the distal tooth (fig. 1-c), which contacts the later. Sides are free vestibular lip or looking to carrillo o lips (fig. 1-d), and tongue that makes the tongue (fig. 1-e). All these surfaces are mainly convex converging proximal lingually free and cervical and occlusal and distal. Contours in sides are proximal trapezoid with the longest side cervical level of free and in keystone, being the longest-level occlusal side. Walls of part may have an internal structure of a tough and resistant material as a metal (fig. 1 and 4-m), which will support turn at far more aesthetically pleasing as ceramics that gives its external configuration or also be devised entire estetico of the same material as ceramics.
