Study Notes
Restoration and Extraction Considerations for Periodontal Disease
- Teeth weakened by periodontal disease require a reliable finish line, which is the chamfer or shoulder at the gingival margin to provide adequate support and prevent further tooth damage.
Crown Margins and Root Furcation
- Crown margins should be kept away from the root furcation to prevent bacteria accumulation, inflammation, and further bone loss.
Restoration Options for Teeth Saved by Periodontal Therapy
- Teeth saved by periodontal therapy often require restorations, such as full-coverage crowns, to protect the tooth from further damage and stress.
Extraction and Implant-Supported Restoration
- In cases where periodontal disease has significantly damaged the tooth, the entire tooth may need to be extracted and replaced with an implant-supported restoration to restore optimal oral function and aesthetics.
Gingival Finish Line Location
- The optimum location for the gingival finish line of a crown preparation is 0.5-1.0 mm onto the root, allowing for adequate crown margin placement and preventing periodontal pocket formation.
