Occlusal Onlays
This innovative alternative preparation to crowns by Prof. Edelhoff / Dr. Ahlers simply saves tooth structure. Occlusal onlays have been introduced as a new, minimally invasive alternative for the restoration of occlusal defects in the hard substance of premolars and molars.
The loss of substance involved with the preparation for occlusal onlays* is less than half of that caused by the preparation of crowns. Take a look at the Step by Step Onlay pdf.
