Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Study Design

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental: Lithium Disilicate CAD/CAM Posts

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.

Group Type EXPERIMENTAL

Lithium Disilicate CAD/CAM Post

Intervention Type DEVICE

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.

Active 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.

Group Type ACTIVE_COMPARATOR

Active Comparator: Polymer-Based CAD/CAM Posts

Intervention Type DEVICE

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.
