[Cementable and adhesive pulpal pins as alternatives to self-threading screws]

Self-threading retentive pins are to be disputed in case of the possible dentinal damage in form of cracks and craze patterns. For a short time two new pin systems are offered on the german market. The essential retention shall be attained by cementing or otherwise by gluing in the pin channel. It is obvious that the promised elimination of cracking and crazing stands in opposition to a significantly reduced retention in the dentin, compared to self-threading systems. A general dispensation of self-threading pins is therefore not to be recommended.
