Clinical Study of Fibre- Reinforced Root Posts with a Ten-Year Observation Period: A Retrospective Study

Area of Science:

• Dental Prosthodontics
• Materials Science in Dentistry
• Clinical Dentistry

Background:

• Fibre-reinforced root posts are widely used in restorative dentistry.
• Long-term clinical data (over 10 years) on their survival and influencing factors are limited.
• Understanding factors affecting longevity is crucial for clinical decision-making.

Purpose of the Study:

• To analyze the survival rates of fibre-reinforced root posts from 2007 to 2017.
• To identify key factors influencing the longevity and success of these restorations.
• To provide long-term clinical insights into root post performance.

Main Methods:

• Retrospective cohort study of 1120 fibre-reinforced root posts.
• Data collected from the Department of Prosthodontics, Goethe-University (2007-2017).
• Analysis included patient demographics, periodontal status, and post characteristics.

Main Results:

• A survival rate of 60.71±14.70 years was observed.
• Periodontal condition emerged as the most significant factor influencing root post survival.
• Two types of posts (Cytec Blanco and DT light post) showed comparable ten-year survival rates (approx. 79%).

Conclusions:

• Patient periodontal health is a critical determinant of root post success.
• The indication for root canal treatment also plays a role in post longevity.
• Structural characteristics of fibre posts appear less influential than patient-related factors.
