Conservative indirect restorations for posterior teeth. Cast versus bonded ceramic

Area of Science:

• Restorative Dentistry
• Dental Materials Science

Background:

• Practitioners have multiple restorative options for extensively broken down posterior teeth.
• Primary choices include cast gold and bonded ceramic inlays, onlays, and partial veneer restorations.
• Selection criteria involve physical properties, marginal integrity, biocompatibility, and pulpal health.

Purpose of the Study:

• To compare cast gold and bonded ceramic restorations for extensively broken down posterior teeth.
• To evaluate the predictability and long-term success of different restorative modalities.
• To inform clinical decision-making based on material properties and patient needs.

Main Methods:

• Comparative analysis of cast gold and bonded ceramic restorations based on existing literature and clinical experience.
• Evaluation of criteria including physical properties, marginal integrity, tooth structure conservation, biocompatibility, and pulpal health.
• Consideration of technical demands and learning curves for both restorative types.

Main Results:

• Cast gold demonstrates superior physical properties and marginal integrity stability.
• Both modalities offer excellent tooth structure conservation and systemic biocompatibility.
• Long-term pulpal health data for bonded restorations are still emerging, while conservative cast gold shows proven success.

Conclusions:

• Partial-coverage cast gold restorations are the most predictable option for extensively broken down posterior teeth currently.
• Bonded ceramic restorations hold potential but require further research regarding material longevity and technique standardization.
• Informed patient choice, considering esthetics and cost-effectiveness, is crucial for optimal restorative outcomes.
