Is 'Digital Dentistry' Dangerous for Teeth? Problems Associated with Zirconia and CAD/CAM Restorations

Area of Science:

• Dentistry
• Materials Science

Background:

• Growing patient demand for aesthetic, metal-free dental restorations.
• Increased adoption of modern ceramic and composite materials in dental practice.
• Influence of patient expectations, sometimes described as narcissistic, on treatment choices.

Purpose of the Study:

• To critically evaluate the trend of metal-free dental restorations.
• To identify potential risks associated with tooth preparation for all-ceramic or composite restorations.
• To question the justification for invasive dental procedures driven by cosmetic concerns.

Main Methods:

• Review of current literature on metal-free dental materials and techniques.
• Analysis of clinical case studies and outcomes.
• Discussion of the biological and mechanical implications of tooth reduction for restorations.

Main Results:

• Metal-free restorations, while aesthetically pleasing, often require significant tooth structure removal.
• Procedures for placing these restorations can be inherently destructive.
• The rationale for extensive preparation, particularly for purely cosmetic reasons, is questioned.

Conclusions:

• Dental professionals must carefully consider the necessity and potential harm of destructive preparation for metal-free restorations.
• A balanced approach is needed, weighing aesthetic desires against biological preservation.
• Further research and ethical guidelines are warranted for cosmetic dental procedures.
