Clinical Evaluation of Two Post Systems for Single Crown Restoration of Anterior Teeth: A Randomized Controlled Clinical Trial
Sponsor: Cairo University
Summary
This randomized controlled trial evaluates two post systems used to restore endodontically treated (root canal treated) maxillary anterior teeth with 1-2 missing coronal walls. Participants will be randomly assigned to receive either a custom-adapted polyethylene fibers post (Ribbond-type, individually formed) or a prefabricated fiber post, followed by a composite core and crown restoration. The primary outcome is the distance between the post and the remaining root canal filling (gutta-percha), measured radiographically, which reflects how well the post adapts within the canal. The secondary outcome is post and restoration retention, assessed clinically using USPHS criteria. Participants will be followed for 6 months. The study aims to determine whether a custom-fitted fiber post provides better adaptation and retention compared to a standard prefabricated fiber post in teeth with significant structural loss.

Custom-Fit UHMWPE Fiber Post with Composite Core
Participants receive a custom-fit UHMWPE fiber post, individually adapted to the canal at chairside, followed by a composite core build-up and definitive crown restoration.
