Summary
This study demonstrates that post-core retained full crowns effectively restore large posterior tooth defects. This dental restoration technique shows a 97% success rate with excellent functional recovery.
Area of Science:
- Restorative Dentistry
- Prosthodontics
- Dental Materials
Context:
- Restoring posterior teeth with large defects presents significant clinical challenges.
- Traditional methods may not always provide adequate strength or longevity.
- The post-core retained full crown offers a viable alternative for complex restorations.
Purpose:
- To evaluate the efficacy and outcomes of post-core retained full crown restorations for posterior teeth with large defects.
- To assess the clinical success rate, functional capacity, and potential complications of this restorative technique.
Summary:
- Sixty posterior teeth with large defects were restored using post-core retained full crowns with various post (spiral-shifted, spiral pin) and core (light-curing resin, amalgam) materials.
- Follow-up (9-19 months) revealed no crown loosening, dislocation, or secondary decay in 97% of cases.
- One instance of gingival irritation was noted. Restored masticatory force averaged 15.9-26.9 kg, meeting functional demands.
Impact:
- This restorative approach demonstrates high clinical success and functional efficiency for compromised posterior teeth.
- The technique is simple to perform and master, offering practical benefits for clinicians.
- It provides a valuable method for preserving residual roots and crowns, enhancing long-term dental health.
