Are e.max crowns better than zirconium crowns for short teeth?
When considering crowns for short teeth, the choice between e.max crowns and zirconia crowns depends on 4 factors. Here is a detailed comparison:
1. Strength and Durability:
e.max crowns: e.max crowns are made of lithium disilicate ceramic, which is known for its strength and durability. They withstand bite forces well and are suitable for most tooth restorations, including short teeth.
Zirconium Oxide Crowns: These crowns are very strong and are often recommended for situations where high strength is required, such as patients with a habit of grinding their teeth. However, they usually require more tooth preparation.
2. Aesthetics:
e.max crowns: These crowns mimic the translucency and color of natural teeth very well, blending seamlessly with natural teeth. They are very aesthetic, so they are popular for visible areas.
Zirconium Oxide Crowns: While zirconia crowns can also achieve good aesthetic results, especially with the help of a skilled technician, they may not be as natural in light transmission as e.max crowns.
3. Tooth preservation:
e.max crowns: generally require minimal tooth preparation compared to zirconia crowns, which is beneficial for preserving natural tooth structure, especially if the teeth are short.
Zirconium oxide crowns: Although they are strong, they generally require more tooth preparation, which may not be ideal for short teeth where natural tooth structure needs to be preserved.
4. Cost:
e.max crowns: generally more expensive than zirconia crowns due to the materials and manufacturing processes involved.
Zirconium oxide crowns: generally more cost-effective, which may be based on budgetary constraints.
Short tooth considerations:
Minimal tooth preparation: For short teeth, preserving natural tooth structure is critical, and e.max crowns generally require less tooth reduction and may be more appropriate.
Aesthetic requirements: For short teeth in visible areas, e.max crowns are preferred because they blend in well with the natural teeth.
Strength requirements: If short teeth are subject to high biting forces, or the patient has habits such as grinding, zirconia crowns may be recommended due to their excellent strength.
In conclusion, the choice between an e.max crown or a zirconia crown for short teeth should be based on a thorough evaluation by the dentist, considering factors such as strength requirements, esthetic goals, tooth protection, and individual dental needs.
