Area of Science:

  • Prosthodontic Dentistry
  • Dental Materials Science
  • Clinical Oral Health

Context:

  • Assesses crown fractures in tapered crowns after 36 months of use.
  • Examines 841 abutment teeth in 209 controlled cases.
  • Investigates the long-term performance of fixed dental prostheses.

Purpose:

  • To evaluate the incidence and risk factors of crown fractures in tapered crowns.
  • To determine the correlation between abutment teeth number and fracture risk.
  • To assess the success rate of saving fractured teeth with post retention.

Summary:

  • A 36-month study of 209 cases found 29 crown fractures among 841 abutment teeth using tapered crowns.
  • No correlation was observed between the number of abutments and crown fracture risk.

  • Incisors, canines, and premolars exhibited similar fracture rates, with 27 teeth saved via post retention.

    • Impact:

    • Provides data on the clinical success and failure modes of tapered crowns in prosthodontics.
    • Informs clinicians about the fracture risk and management of tapered crown restorations.
    • Highlights the efficacy of post retention in preserving teeth with crown fractures.
