Direct or indirect veneers?. Overview with a focus on ceramic restorations

Area of Science:

• Dentistry
• Restorative Dentistry
• Esthetic Dentistry

Background:

• Minimally invasive anterior veneer restorations are crucial in modern esthetic dentistry.
• Direct composite resin and indirect ceramic veneers are effective conservative treatment options.

Purpose of the Study:

• To provide a comprehensive clinical and scientific overview of anterior veneer restorations.
• To outline indications, preparation, adhesive procedures, outcomes, and long-term performance.
• To critically review adhesive protocols and discuss long-term survival data.

Main Methods:

• Review of clinical and scientific literature on direct composite and indirect ceramic veneers.
• Detailed exploration of concepts for indirect ceramic veneers: additive design, project-guided preparations, mock-up-driven techniques.
• Critical review of adhesive protocols: ceramic conditioning, silanization, tooth surface treatment.

Main Results:

• Indirect ceramic veneers show superior long-term longevity compared to composite resin veneers.
• Modern composite resin materials offer significant advantages and predictable outcomes.
• Both veneer types, when indicated and used appropriately, lead to high patient satisfaction.

Conclusions:

• Both composite resin and ceramic veneers are viable treatment options for esthetic dentistry.
• Enamel preservation is a key consideration in preparation protocols.
• Appropriate material selection and technique ensure predictable esthetic and functional results.
