To reduce the cementation line, consequently reducing the reducing luting agent dependence and to promote ideal retention. Composite resin fiberglass post relined are most viable for these cases. Anatomical post (AP), as they are called, undergo an individualization to better adapt them to the conduit according to anatomy of the dental remnant. Firstly, a radiographic and endodontic evaluation of the element was performed. Rubber dam was made. Root Preparation was done after selection and adaptation of the FP. Lubricated the conduit with water soluble gel and surface treatment was performed. Composite resin was applied over the post and leaded to the conduit, to model the conduit, photopolymerized 5 seconds, withdraw from the mouth and performed final photopolymerization for 60 seconds. Reinserted the individualized post to make sure the adjustment is correct. Next, the AP and the conduit were prepared for the correct cementation of the anatomical post. Proceeded with the reanatomization in the core, and correct preparation for the provisional crown and later replace with definitive prosthetic element. Checked the occlusion and aesthetic requirements such as color, anatomy, and preference of the patient. In this case report, we discuss the technique of rehabilitation of a prosthetic element with PA to show an alternative treatment for teeth with broad ducts and weakened roots, an efficient and easily applied technique.
