Summary

Modern post-and-core restorations utilize tooth-colored, fiber-reinforced composite posts or titanium posts with resin cement. Long-term studies are needed for fiber posts, but current techniques offer improved outcomes.

Area of Science:

  • Dental materials science
  • Restorative dentistry
  • Prosthodontics

Background:

  • Post-and-core restoration techniques have evolved significantly.
  • Current research favors fiber-reinforced composite posts or titanium alloy posts with resin cement and composite build-ups.

Purpose of the Study:

  • To review current practices in post-and-core restorations.
  • To provide guidance on the selection and application of posts.
  • To highlight promising materials and future research needs.

Main Methods:

  • Literature review of current techniques and materials.
  • Analysis of research supporting resin-based composite posts and titanium alloy posts.
  • Clinical observations and recommendations.

Main Results:

  • Tooth-colored, fiber-reinforced resin-based composite posts and titanium alloy posts cemented with resin cement are current standards.
  • Resin-based composite build-ups are integral to these techniques.
  • Fiber-reinforced posts show promise, but require long-term clinical data.

Conclusions:

  • Current post-and-core techniques emphasize specific material combinations for optimal outcomes.
  • Further long-term clinical evaluation is necessary for fiber-reinforced posts.
  • Guidelines for post selection and usage are provided.
