Background and Objective: This study investigates the relationship between porcelain-fused-to-metal (PFM) crowns and peri-abutment bone, focusing on restoration success and abutment tooth health. It highlights the role of effective occlusal force transfer and bone remodeling. Cone Beam Computed Tomography is emphasized for its precise post-placement monitoring and diagnostics, improving care standards.
Methodology: The research evaluates buccal and lingual bone height changes around abutments with PFM crowns. Selected patients received single crowns, with CBCT scans taken before (P0) and six months after (P1) crown placement. Measurements from the root apex to buccal and lingual alveolar bone were recorded using CBCT software. Comparative analysis aims to optimize single crown treatments by assessing the impact on bone structures.
Results: Pre- and post-treatment comparisons showed no statistically significant difference in buccal bone height (p>0.05). For lingual bone height, although post-treatment values were higher, the difference was not statistically significant (p<0.01).
Conclusion: The study concludes that PFM crowns do not significantly alter peri-abutment bone height within six months, providing insights for optimizing single crown treatments and understanding bone remodeling in response to prosthodontic interventions.
