the crown 100 the spatula type end can either be a grooved spatula 32 as seen in fig5 or a perforated spatula 34 as seen in fig6 the carrier 10 is connected to the post 20 by a thin connector 40 the thin connector 40 is made of the same material as is the carrier 10 and can be integral with the carrier 10 this thin connector 40 defines a break point the thin connector 40 by being smaller in diameter than the carrier 40 will break and thereby sever the connection between the post 20 and carrier 10 should undue pressure be applied to the post 20 if excessive pressure is applied to a crown 100 after completion of the buildup and crown procedure that excessive pressure is transferred to the post 20 within the root the post will in turn transfer the pressure to the carrier 10 that is located within the root by being in contact with the root the carrier 10 would transfer the pressure to the root this pressure if sufficient would result in root breakage the thin connector 40 will break if undue pressure is applied to it therefore any pressure that is placed upon the tooth.
