Made-up double-crown system as holder for tooth implant - uses titanium, precious or non-precious metal with inner crown for given jaw implant heads, prefabricated and screwed or cemented in position

摘要

The choice of occlusal gap size, the convergence angle between inner and outer crowns, the elasicity of the outer crown by means of mass prodn. provides a variable but always definable release force, and the outer crown is either prepared using the plastic or ceramic mxt. techniques. The inner crown for predetermined jaw implant heads which are prefabricated can be screwed or cemented into position (2). The release force can be adjusted via additional prefabricated bolts (3) machined into the outer and inner crowns. The inner crown can be formed as an implant head during the production process and connected to other implanted heads by screwing or cementing. USE - In density, as a prefabricated double crown system system for implanted tooth replacements.
