Brief summary

This study investigates the survival and success rates of endodontic posts exclusively fabricated using the CAD/CAM digital method over a period of 5 years of intraoral use. The objective is to evaluate the efficacy and long-term outcomes of the digital approach compared to traditional techniques, aiming to determine the reliability and precision of CAD/CAM technology in the fabrication of endodontic post restorations.

Detailed description

This clinical study aims to evaluate the survival and success rates of endodontic posts exclusively fabricated using the CAD/CAM digital method over a period of 5 years of intraoral use. The study focuses on the utilization of advanced digital technology for the design and fabrication of endodontic posts, which replaces traditional impression-taking and analog methods. Participants in the study will undergo treatment where digital intraoral scanners will capture the post-space anatomy, and CAD software will be used to design custom posts that are then milled using CAM technology. The fabricated posts will be evaluated for fit, stability, and clinical performance over a prolonged period. The primary outcome measures include the survival rate of the posts (absence of dislodgement or failure) and the success rate, which incorporates the functional and aesthetic integration of the post with the surrounding dental structures. Secondary outcomes will assess the incidence of complications such as root fractures, debonding, and endodontic failure. This study distinguishes itself by exclusively using the digital CAD/CAM approach, with no involvement of traditional methods, ensuring precision and consistency in post fabrication. It aims to provide comprehensive data on the effectiveness and reliability of CAD/CAM technology for endodontic applications, offering insights that could influence clinical protocols and materials used in restorative dentistry

Interventions

DEVICELithium Disilicate CAD/CAM Post

Patients in this arm receive custom CAD/CAM posts fabricated from lithium disilicate. All posts are designed, milled, and cemented using standardized preparation, adhesive, and cementation protocols. Clinical follow-up evaluates post survival, success rates, biological response, and the need for repair or replacement over time.

DEVICEActive Comparator: Polymer-Based CAD/CAM Posts

Patients in this arm receive custom CAD/CAM posts fabricated from high-performance polymer materials. Posts are manufactured and cemented using the same standardized clinical workflow applied in Arm 1. This arm allows comparison of survival, success rates, functional stability, and biological outcomes relative to lithium disilicate CAD/CAM posts.

Masking description

This is an open-label trial; no parties are masked in this study.

Intervention model description

This study uses a parallel-group interventional model in which patients are allocated to different treatment arms corresponding to distinct types of indirect restorations or restorative materials. Each participant receives only the assigned intervention, performed under standardized preparation, adhesive, and cementation protocols. The model allows comparison of clinical performance, survival, and success rates among the different restorative approaches. All groups are followed longitudinally using predefined clinical and radiographic criteria to assess restoration integrity, functional stability, biological compatibility, and the need for repair or replacement.

Design outcomes

Primary

MeasureTime frameDescription
Survival Rate of CAD/CAM Endodontic PostsAssessed over a period of 5 years post-placementThe primary outcome measure is the survival rate of endodontic posts fabricated using the CAD/CAM digital method. Survival is defined as the post remaining in situ without any signs of dislodgement, root fracture, or clinical failure necessitating replacement. Posts will be evaluated periodically to monitor their clinical performance and integrity, ensuring that no adverse events such as post loosening or tooth failure occur
