Summary
Resin-based composites are ideal for adhesive luting, offering superior properties and wear resistance. Proper technique ensures excellent clinical performance for indirect restorations, minimizing hypersensitivity and maximizing longevity.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Biomaterials Engineering
Background:
- Adhesive luting is crucial for indirect restorations, demanding careful material selection and application techniques.
- Understanding material characteristics, bonding efficacy, and clinical performance is vital for successful outcomes.
Purpose of the Study:
- To evaluate material properties, film thickness, overhang control, and bonding capabilities of adhesive luting agents.
- To assess wear characteristics, clinical performance, and potential for hypersensitivity with various luting composites.
- To review the possibilities and limitations of adhesively luted indirect restorations.
Main Methods:
- A comprehensive literature review of in vitro and in vivo studies was conducted.
- Studies focused on material characteristics, bonding protocols, and clinical evaluations of luting procedures.
- Analysis included factors such as film thickness, wear, and patient sensitivity.
Main Results:
- Resin-based composites, particularly fine particle hybrid types, exhibit superior properties and wear behavior for adhesive luting.
- Optimal bonding to ceramic and resin composite inlays requires specific pre-treatments like hydrofluoric acid or silica coating.
- Multi-step bonding systems are recommended for robust adhesion to tooth substrates, minimizing hypersensitivity.
- Clinical performance of adhesively luted indirect restorations is promising, with successful outcomes reported up to 10 years.
Conclusions:
- Resin-based composites are the preferred materials for adhesive luting due to their favorable properties and wear resistance.
- Effective bonding and overhang control are achievable with appropriate material selection and application techniques, including the ultrasonic insertion method.
- Adhesive luting procedures, when performed correctly, demonstrate excellent long-term clinical performance and patient comfort for indirect restorations.
