🦷 Bevel Design in Crown Preparation — A Quick Clinical Guide
One preparation design does not fit every restorative material.
The functional cusp bevel provides adequate restorative thickness on:
🔹 Maxillary teeth → Palatal cusps
🔹 Mandibular teeth → Buccal cusps
Meanwhile, marginal bevels have more selective indications, particularly with metal-containing restorations, while modern all-ceramic restorations generally require appropriately designed rounded shoulders or chamfers rather than thin beveled ceramic margins.
⚠️ Common preparation mistakes include:
• Missing the functional cusp bevel
• Insufficient occlusal clearance
• Excessive tooth reduction
• Sharp internal angles
• Using the same finish line for every material
💡 Remember:
Preserve tooth structure while creating adequate space for the restorative material.
