Fiber-reinforced fixed partial dentures: a preliminary retrospective clinical study

Area of Science:

• Dental Materials Science
• Prosthodontics
• Biomaterials Engineering

Background:

• Fixed partial dentures (FPDs) are crucial for restoring missing teeth.
• Traditional FPDs can be invasive; fiber-reinforced composites offer a less invasive alternative.
• Evaluating the long-term clinical performance of novel materials is essential.

Purpose of the Study:

• To assess the clinical performance, specifically the retention rate, of fiber-reinforced composite FPDs.
• To investigate the durability of FPDs fabricated with polyethylene fiber (Ribbond) and composite resin.
• To provide preliminary data on the survival of these advanced dental restorations.

Main Methods:

• Nineteen polyethylene fiber-reinforced composite FPDs were fabricated and placed in thirteen patients.
• Pontic materials included extracted teeth, acrylic resin teeth, or composite resin.
• Clinical evaluation focused on retention rate, categorizing outcomes as Complete Survival (CS), Survival with Rebonding (SR), or Failure (F).

Main Results:

• A high retention rate was observed, with 94.75% of FPDs classified as Complete Survival (CS).
• Only one FPD (5.25%) required rebonding (Survival with Rebonding, SR), with no complete failures reported.
• The mean survival time, estimated using the Kaplan-Meier method, was 42.3 months.

Conclusions:

• Polyethylene fiber-reinforced composite FPDs demonstrate a favorable retention rate and promising clinical performance.
• These findings suggest that fiber-reinforced composite FPDs are a viable, durable option for dental restoration.
• Further long-term studies are warranted to confirm these preliminary positive results.
