Microscopes in Restorative Dentistry

Dr. Marco Gresnigt from the Netherlands presents a detailed lecture on the application of microscopes in restorative dentistry. He begins by outlining his academic and research background, including his work with the Biomimala group focused on biomimetic dentistry. The lecture is structured around three key topics: the importance of magnification, practical microscope use, and their benefits in clinical settings. He highlights that 60–80% of dentists experience neck and back pain, and demonstrates how microscopes enhance ergonomics by enabling upright posture during procedures.

Clinical applications include direct vision for anterior teeth, mirror work for upper posteriors, and improved patient positioning for lower teeth. Research findings show that higher magnification aids in detecting restoration defects and achieving better marginal fit in crowns. Dr. Gresnigt also shares case studies on ceramic restorations, illustrating how microscopes help identify glaze contamination that can compromise bonding. For anterior restorations, he explains techniques for achieving seamless margins in laminate veneers by removing excess cement before light curing rather than tack curing.

He concludes that microscopes improve restoration quality, reduce physical strain, and enhance practitioner satisfaction and patient outcomes, though they require additional time and adjustment to integrate into practice.
