Marco Gresnigt graduated cum laude in 2005 and in 2012 he received his PhD (on laminate veneers) from the University of Groningen. He is currently associate professor in restorative dentistry, conducts practice based research in the field of restorative/adhesive dentistry and teaches aesthetic and reconstructive dentistry at clinic. He has 5 PhD students, 17 master students, 2 internships and publishes in international journals (>65 peer reviewed; h-factor 27) especially in the field of adhesive restorative dentistry. He works at the center for special dental care at the Martini Hospital Groningen where he performs restorative and esthetic treatments using a surgical microscope. He gives keynote lectures and masterclasses (inter)nationally in the field of esthetic and adhesive dentistry ( He has won several awards such as the GC world clinical case award, Smile award, EAED innovation award and numerous scientific awards. He was the president of the international Bio-Emulation group and has a group for innovative restorative dental research





In the first part of my presentation, I will cover the topic of laminate veneers bonded to teeth with existing composite restorations or exposed dentine. When teeth have large exposed dentin and/or composite restorations are present, many dentists tend to make a crown. However, current adhesive systems allow us to bond laminate veneers to teeth with existing restorations or IDS. This lecture will cover both in-house scientific studies and clinical workflow. A step-by-step protocol for reliable bonding of laminate veneers will be given.

OBJECTIVES: At the completion of the course, participants will be able to:

  • How to be minimal invasive in challenging anterior situations

  • How to apply an IDS layer and create an optimal adhesion in the luting appointment

  • If we can leave existing restorations underneath ceramic partial restorations



Missing a tooth in the esthetic region is an emotional burden for young people. Because the tooth-jaw complex is still growing, it is sometimes difficult to create an optimal treatment plan. In this presentation, several treatment modalities will be explained. Our new invention the contact-point bridge will be presented, a full ceramic bonded bridge without any preparation or wings. As this is a non-invasive treatment, it can be a good esthetic alternative for young patients. In this presentation, both science and practical/clinical procedures will be highlighted. 

OBJECTIVES: At the completion of the course, participants will be able to:

  • How to be minimal invasive in trauma cases

  • What the different treatment options are for missing anterior teeth in young patients

  • About auto-transplantations and a novel non prep bridge without wings.
