This Concept Map, created with IHMC CmapTools, has information related to: RESISTANCE FORM, Small groove placement in root canal wall used in tooth completely lost coronal dentin, Anti-rotational elements such as Preparation of small cavity, Anti-rotational elements such as Auxiliary pin, POST DESIGN with conclusions such as High stress, Glass fiber posts have an elastic modulus (flexibiliy) similar to dentin, lower stresses during in-vitro testing with less catastrophic failures ???? fractures may occur in posts rather than in the remaining tooth structure, Glass fiber posts lead to lower stresses during in-vitro testing with less catastrophic failures, improves resistance to laterally directed forces, Threaded posts can distribute stress evenly if the posts are backed off a half-turn, POST DESIGN with conclusions such as Greatest stress concentrations, POST DESIGN with conclusions such as Parallel-sided post, POST DESIGN with conclusions such as Glass fiber posts, Parallel-sided post may heighten stresses at the apex, ROTATIONAL RESISTANCE prevents Post with a circular cross section from rotation during function, Threaded posts can Heighten stress concentrations, POST DESIGN with conclusions such as Stress reduction, Greatest stress concentrations are found at the apex, Preparation of small cavity finished with condensing the amalgam into the cavity after the post is cemented, Small groove placement in root canal wall located path of placement of the post and core restoration, Heighten stress concentrations during loading
