Product Description
Short tapered chamfer round, depth marking at 1mm - refer to set LD2246
Occlusal Onlays - The innovative alternative to crowns.

The minimally invasive approach:  Occlusal onlays ("Table Tops").  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.

Advantages:
Clearly reduced loss of hard dental substance - and fewer biological risks.

Disadvantages:
The preparation of occlusal onlays used to be difficult without special instruments from a technical point of view.

Pre-Preparation
According to the information currently provided by manufacturers, occlusal onlays made of lithium silicate require a minimum thickness of 1 mm.  Teeth damaged by biocorrosion often have an irregular shape.  It is, therefore ,recommended to unite the steps of depth marking and pre-contouring in a pre-preparation process.  To this end, we have provided an abrasive diamond instrument of a suitable shape with a black laser mark at 1 mm from the instrument tip.  Whenever you wish to remove occlusal substance, apply the instrument 855D to the occlusal surface in a vertical position and prepare guide grooves with depth of 1 mm.  Then, even out the occlusal surface making sure to maintain the correct cusp-fossa relationship and level any sharp burr at the edges of the occlusal surface.  This way, you can control the amount of substance removed already at the pre-preparation stage completely without a depth marker, unless of course the loss of dental hard substance is so extensive that there is no need to create further occlusal space.
