Abstract

Continuous research and advancements in material science have significantly influenced restorative dentistry, shifting the focus from conventional restorations to bonded restorations. The introduction of the Sevriton Cavity Seal by Oskar Hagger in the 1940s and Buonocore’s application of phosphoric acid (PA) in 1955 laid the foundation for modern adhesive dentistry. The principle of preserving existing tooth structure over replacing missing portions has driven the adoption of minimally invasive techniques, which enhance prognosis while maintaining tooth integrity. Modern bonding techniques prioritize clinical efficiency while maintaining high bond strength and restoration quality. Improved adhesion enhances conservative tooth preparation, esthetics, and long-term restoration success by minimizing microleakage and expanding versatility. Enamel preservation remains paramount, as its superior bonding properties and higher mineral content contribute to stronger, more durable restorations. Magnification technology, including loupes and microscopes, has further revolutionized minimally invasive dentistry by enhancing precision. In addition, advancements in veneer preparation design emphasize enamel conservation. Veneers as thin as 0.3–0.5 mm, enabled by modern dental ceramics, allow for minimal tooth reduction while maintaining adhesion and biomechanical integrity. Studies indicate that etch-and-rinse adhesives provide stronger enamel bonds than self-etch adhesives, and selective enamel etching with PA enhances bond strength. These innovations not only improve the structural integrity and longevity of restorations but also optimize pressure tolerance in prostheses. With enhanced materials, bonding techniques, and magnification tools, minimally invasive bonded restorations now provide a superior alternative to conventional crowns and bridges. This review article highlights recent advancements in bonding materials, adhesive techniques, and preparation designs.
