Angelus Metal post serrated or roughened surface is more retentive than a smooth one. Controlled grooving of the post and root canal also increases the retention of the post
It must be cemented passively. Active Screwable posts are harmful to the dental structures
Superior retention is observed in active THREADED POST, but it exerts a greater amount of stress on the remaining tooth structure which increase the potential for root fracture.
Currently there are 3 types of cement available for post cementation Resin cements, GIC & zinc phosphate.
Self cure resin cement is the material of choice for post cementation as it has highest compressive strength along with negligible solubility. GIC bonds chemically with the dentin and is not technique sensitive. The most traditional of all cements is zinc phosphate, which has adequate physical properties, economic and easy to use as of which it remains as choice of material for post cementation for around decades.
The technique of making prosthesis with pre-fabricated Fiber/Metal posts allows for creation of the post/core in a single session, eliminating steps and laboratory costs
